1. Rigoglioso Air Purifier – The Cheap Choice


Rigoglioso is not a well-known brand name, and although it sounds Italian, it is actually a Chinese company selling on Amazon. This model is probably the definition of what we would call an “entry-level” pick. Cheap, yet well-designed and energy-efficient, it will do what it’s meant to – nothing more, nothing less.

    HEPA Air Purifier, filtering 99.97% of particles as small as 0.3 microns, including dust, pollen, cigarette smoke, odours, mould spores, and pet dander
    Portable Air Freshener
    Ionic Air Purifier
    One-touch Switch
  • Package Contents:
    1 x Air Purifier
    1 x The Manual
    1 x USB cable (plug adapter not included)
    1 x Filter (In the air purifier)

Design & Features

Compact and lightweight, Rigoglioso is obviously designed for small rooms and apartments, as well as offices. Its design could not have been simpler: with a single fan speed setting, it does not require much reading or experimenting to learn how to use it. The button on the top has a knack to it: pressing it once turns the unit on and pressing it twice places it into sleep mode.

The power is supplied by a USB data cable which is included, but you need to plug it into something like a phone charger plug. The built-in nightlight is dimmed on sleep mode, and the unit turns itself off automatically after 8 hours. The dimmed light stays on, which is a pity, especially for a light sleeper.

The Rigoglioso removes odours efficiently and is ideal for small rooms. This unit has a True HEPA (High-Efficiency Particulate Air) filter as well as an activated carbon filter, which ensures proper air filtering. Still, people with serious respiratory problems or allergies should opt for a more powerful unit, which will be able to filter the air much faster.

As to the noise, you can expect some, but nothing too disturbing, not because of some advanced technological feature, but because of its small suction power.

  • Cheaply price
  • Compact and lightweight, easy to move around
  • Ideal for small spaces
  • Value for money
  • Although dimmed, nightlight stays on
  • Turns itself off on night mode after 8 hours
  • Small power

Our Opinion

The Rigoglioso air purifier does an efficient job of removing odours and is ideal if you are on a budget and just need it for a small room. It is definitely one of the best entry-level air purifiers on the market.

2. TaoTronics HEPA Air Purifier


The TaoTronics HEPA Air Purifier is designed for medium-sized rooms, but when used in such, it proves extremely powerful and efficient. Offered at an extremely appealing price and coming well-featured, TaoTronics will not let you down.

    1 x 3-in-1 True HEPA Air Filter
    1 x User Guide
  • 4 Fan Speeds
  • Average Filter Replacement: 3 to 6 Months
  • Warranty: 3 Years Months

Design & Features

The unit arrives fully assembled. The only thing you have to do is take off the covers of the filters before activating for the first time. The first thing that catches the eye in this unit is, of course, its surprisingly small size (a mere 10.6-inch height and 7.6-inch diameter) and cylindrical design, which allows you to place almost anywhere – even upon your office, table or bedside table. Besides, it is extremely lightweight too; you can easily change its place at will.

Drawing in the air from its base and releasing it filtered through spiral vents from top, which effectively diffuse the air evenly to a greater distance. Just make sure it has plenty of room around it, to optimize airflow. All controls are on the top too. Everything pretty standard and straightforward, among which the button activating the Sleep Mode, the fan speed selection, as well as the filter replacement indicator. Replacing the filter is a breeze; just unscrew the unit in the middle and you will have immediate access to the filters.

Now let’s move to its operation. The TaoTronics HEPA Air Purifier utilizes a three-stage filtration system: first, the air is filtered through a mesh pre-filter, designed to catch large particles, like pet hair and allow the inner filters to tend to small air particles without getting clogged – thus saving you money from having to replace them too often.

Next comes the true HEPA filter, designed to remove the majority of the air contaminants – hence the one that needs replacement more frequently. The manufacturer’s claim of it being able to remove 99.97 per cent of particles as small as 0.3 microns in diameter (including allergens) seems genuine enough. The air we tested it in was filled with dust and ash and we saw a clear difference in less than a quarter of an hour.

The third filter is that of the activated carbon, designed to rid the air from odours, chemical contaminants, and VOCs. According to the manufacturer, the last two filters require replacement every 3 to 6 months, depending on the quality of the air in your area. Unfortunately, the unit lacks the most advanced feature of air quality detection and automatic adjustment of the fan speed and mode of operation – something that would extend considerably the life of the filters.

With four different fan speed options and mastering a maximum capacity of 150 square meters per hour, it is more than capable of filtering the air rooms of up to 161 square feet in size, in around 10 minutes. So, for such spaces, it is rather powerful. The noise level range is more than acceptable, reaching a maximum (according to our readings) of 50 dB – amounting to a relatively loud white noise. On the contrary, the Sleep Mode turns the unit’s operation to almost silent. What’s best in this mode, which is not always found in other air purifiers of this price range, is that total deactivation of the LED lights – a thoughtful addition to people who are rather sensitive to light during their sleep.

We would not expect smart technology from a unit of this price, but a remote control would surely sweeten the deal even more.

  • Compact and lightweight, easy to transfer from one room to another
  • Easy to use
  • Great power and efficiency when used in the space it is designed for
  • Almost silent sleep mode
  • Optional night light
  • No automatic air detection
  • No remote control

Our Opinion

Small yet mighty for its size, the TaoTronics HEPA Air Purifier is affordable, proved reliable, and is an elegant addition to any room.

3. Levoit Air Purifier LV-H132


The Levoit LV-H132 is a smaller sized air purifier which is ideal for a bedroom, workroom, office, studio or could even be used in a hospital room.  It is small enough to place on a nightstand.

  • Package Includes:
    1 x LV-H132 Compact HEPA Air Purifier
    1 x Three-stage Filtration Filter (Fine Preliminary Filter, True HEPA Filter, Activated Carbon Filter)
    1 x User Manual
    1 x UK 3-Pin Mains Power Cable
  • 2-Year Warranty & Lifetime Support

Design & Features

Designed to filter the air of small rooms of up to 86 square feet, the Levoit LV-H132 and is light and compact – hence easy to move and place anywhere.  It stands 14.5 inches high and is cylindrical in shape with a diameter of 8.5 inches and weighs 6.6 pounds. It requires about 14 inches free space from walls, radiators or anything that could interfere with its airflow.

It is very easy to set-up: just remove the plastic protective wrapping then give a half-turn of the base to remove the bottom plate, giving access to the filter.  Remove the plastic wrapping, place the filter back to its place, reattach the base and plug it in – and you are done. There is a manual and instructions for setup which are easy to understand and clear.

For its dimensions and price, the LV-H132 proved surprisingly powerful. There are 3 modes for use: one for nighttime use, one for continuous use throughout the day, and a high mode for extreme conditions. It features with a 3-Stage Filtration System, the so-called “Pre-Filter”, the “True HEPA Filter”, and the high-efficiency activated carbon filter. Its promise for eliminating 99.97% of all contaminants down to 0.3 microns, including allergens, smoke, dust, mould, pet hairs and odours surely seems a bit of an exaggeration for an entry-level air purifier of this sort, but we saw nothing in our tests that gave us any reason to doubt it.

Fan Speed settings are three, namely low, medium, or high. The two higher levels produce some discernable noise – but I am not the best judge on these stuff since I often use white noise sources to sleep. The unit does come with an Ultra-Silent Operation, which, according to the manufacturer reduces the noise to 25dB. We found it to be a little higher – but still within the “silent-quiet” radius. Besides, the unit is not powerful enough to cause a problem during your sleep even at a medium or high level. On the other hand, do not expect it to be as efficient in the Ultra-Silent mode in air filtering.

Light sleepers would also like to know that there is a Night Light & Display Off Function, allowing you to choose between 2 brightness settings and pick the one that will not disturb you at night. Unfortunately, even the dimmer setting may prove a bit too bright for someone who has a high level of sensitivity.

The unit has a Filter Change Reminder, which is handy but something that is pretty standard nowadays. According to the manufacturer, you will have to replace the filter every 6 – 8 months, depending on use and air quality. Generally speaking, LV-H132 proved very easy to use. To access each setting, you just need a light touch of the fingertip.

Also note that the LV-H132 is 100% ozone free, which means is a great pick for families with toddlers and or people who suffer from asthma.

  • Highly effective in a small space
  • Quiet
  • Will fit anywhere
  • Light, easy to move & operates
  • Nightlight
  • Blue nightlight is a little too bright

Our Opinion

If you only have a small area in which you need an air purifier, this one is excellent.  It will even remove the strong smell of paint in a studio.  It is efficient, quiet, easy to set up and use.

4. RENPHO Air Purifier


Another stylish air purifier, yet much more powerful unit, the Renpho air purifier is designed for rooms of up to 240 square feet – ideal for small apartments and houses. Offering a decent number of handy features, reliability and efficiency, it easily crept in our 7 best list.

  • 3 Fan Speeds with Sleep Mode and Whisper-Quiet Operation

  • Two light modes
  • Included in the Package:
    1 x RENPHO Air Purifier
    1 x True HEPA Filter (Pre-Installed)
    1 x User Manual

Design & Features

Contrary to older models of this brand, this unit features a really extravagant yet elegant design. Cylindrical, with a matt black hue, with the controls on the top and a nice, orange backlight that makes a fiery contrast with the black casing, it surely is the kind of appliance that you will either hate or fall in love at first sight. As to its size, it will certainly not be an issue even for relatively small rooms.

All controls are located on the top of the purifier, including the Adjust Fan Speed (high, medium, low), modes of operation, and filter life indicator, which flashes when the filter needs to be replaced.

It is very easy and simple to use, so we best move to things that really matter especially the air filtering process. This one utilises a five-stage process that includes a Pre-filter (designed to capture larger particles, like pet dander and dust), the True HEPA filter (for allergens particles as small as 0.3 microns), the activated carbon filter, which is essential for eliminating odours and smoke, as well as a Net filter.

Overall, its performance was excellent, especially when compared to its predecessors, who were entry-level picks. Indeed, we found it to be efficient, with good airflow, even when we tested it in a room slightly bigger from the one designed for.

The air is distributed exclusively out the top of the unit; actually, it would be nice, since we go up the price scale, to see a different air distribution pattern. Still, this does not affect the efficiency of the machine.

A nice addition is the auto shut-off, which can be set after 2, 4 or 8 hours. Unfortunately, this unit also lacks an automated air quality monitoring function, but this is hardly a deal-breaker since it is a feature we usually see at pricier models. It is also not smart tech compatible, nor does it have a remote control.

As to the noise, it surely proved one of the quietest air purifiers of this price range we have tested – when set in the Whisper-Quiet mode. When operating in full power, you should expect some white noise that is barely noticeable. It would be nice if all the lights went off in the sleep mode, but those that do remain on are pretty dim and discreet.

  • Nice design
  • Easy to use
  • 5-stage filtration
  • Compact body style
  • No Wi-Fi connection
  • No automatic air quality detection

Our Opinion

Designed for small offices and apartments, the new Renpho air purifier is certainly a great upgrade. Compact, reliable, much more powerful and with a 5-stage filtration process, it will keep the air clean – as long as it is used in rooms of the dimensions it is designed for.

5. Pro Breeze 5-in-1 Air Purifier – Value-for-Money


The Pro Breeze 5-in-1 air purifier takes it up a notch, featuring a five-stage purification system and promising people suffering from allergies the best breathing of their lives. Let us see if it lives up to this promise.

  • Features:
    Negative Ion Generator
    Built-In Timers
    Night-time mode for undisturbed sleep
    Negative Ion Generator
  • Fully Complied with CE and RoHS

Design & Features

Design-wise, Pro Breeze is a truly compact and beautiful unit. Solidly built and featuring a minimalistic and futuristic simplicity, it stands out with its with a silver mid-front circle with a stylish blue backlight surrounding the touch panel, which allows you to adjust the airspeed and set the timer and sleep mode.

Being far more powerful than our first pick, the Pro Breeze is suitable for spaces of up to 430 square feet, making it a great pick for large apartments and small to mid-sized houses.

Adequately equipped, it comes with the standard features of a contemporary air purifier, including automatic timers (allowing you to set it to switch on or off after 1.2 or 4 hours), while the nighttime mode ensures you can enjoy a peaceful sleep.

Now, let us check its air filtering performance. As already mentioned, Pro Breeze uses a five-stage filtering system, which rids the air of allergens, dust, mould, hairs and odours. According to the manufacturer its can capture up to 99.97% of air particles measuring even as low as 0.3 microns – and we saw nothing that proved otherwise.

The Pro Breeze 5-in-1 air purifier consists primarily of a Pre-Filter, this is the first stage which air passes through and will trap large airborne particles like pet hair and dust. The next stage is when the air passes through a True HEPA (High-Efficiency Particulate Air) Filter, which captures smaller particles like dust mites, pollen and pet dander, which is skin shed from pets that can cause allergies.  By this stage, 99.97% of 0.3-micron particles have been captured by the filter. Following is an Activated Carbon Filter which will absorb odours from the home, contaminants and pollutants. The last filter is a Cold Catalyst Filter where any remaining impurities are captured.

The unit has a negative ion generator which neutralises and cleans any pollutants from the air with the negative ions. These negative ions attach themselves to unwanted positive ions in the air, thereby purifying the air and thereby enhancing your mood. Negative ion units are very efficient at getting rid of airborne bacterial infections.  They also reduce static electricity build-up in electronic equipment. The large surface areas of the filters ensure that the air is purified to the highest degree possible.

Also, note that there is an option to turn off the ionizer if you are concerned about the negative effects of the small number of ozone ionizers produce.

The Pro Breeze also deals with Volatile Organic Compounds (VOCs) which can prove harmful, (such as formaldehyde).  This is especially useful in an office where there are photocopying machines.  This air purifier can actually eliminate many carcinogens.

One of the most important characteristics, though, is its Clean Air Delivery Rate (CADR), which rises to a little less than 220 m3/h – amazing for a unit of this price range.

Now, whenever you see comments about the great power of an air purifier, then you should worry about their noise levels. Fortunately, the Pro Breeze is indeed on the quietest air purifiers of its price range. In fact, it has been awarded an internationally renowned “Quiet Mark”, given exclusively to the quietest units on the market. This makes it perfect for light sleepers as well as bedrooms, living rooms and offices.

Still, please note that the whole “Quiet Mark” thing applies only to the Silent mode. Otherwise, the noise is discernible and – when operating on the highest possible setting – easily discernible.

Unfortunately, the unit itself lacks the ability of automatically adjusting its operation by monitoring the quality of the air. This feature, however, is hardly expected in units of this price. It would be nice, though, if it could be operated through a smartphone or at least through remote control.

  • 5 Air filters for the highest possible degree of pure air
  • Ideal for up to 500 square feet
  • Perfect for anyone with allergies
  • Will keep you healthy
  • No smart technology or remote control
  • No automatic air quality monitoring

Our Opinion 

Well-designed and constructed, efficient and budget-friendly, the Pro Breeze 5-1 lives up to its reputation as one of the most efficient air purifiers of its price range.

6. Levoit LV-PUR131 Air Purifier


We have already spoken of one of Levoit’s cheaper models, but now we come to a pricier one – and one of the most successful air purifiers of the last years, the LV-PUR131. Built to last, with unrivalled efficiency and with plenty of automated features, Levoit LV-PUR131 is certainly worth your consideration.

  • 1 – 12 Hours Timer Function

Design & Features

As usual, the unit comes fully assembled – the only thing you have to do is uncover the filters. One thing is for sure: LV-PUR131’s design is a lot different than the rest of our picks. It features a rectangular shape, with an almost flat top panel, where also you will find a single air outlet. This design has its advantages and disadvantages: it affords more space inside the unit, thus allowing a more thorough filtering of the air, as well as a bigger quantity of it being filtered much faster.

On the other hand, this design affords more weight (around 11 lbs) to the unit and makes it considerably less comfortable.

As to the filtration system, it utilizes three different stages: the Pre-filter stage, ridding the air of dust, pet dander and hair, mould and fungi; the True HEPA filter, capable of filtering out 99.97% of air contaminants of diameter as small as 0.3 microns (including viruses, pollen, and bacteria); last but not least, the activated Carbon Filter, eliminating the odours and smoke. Our tests indeed showed excellent performance, at an impressive speed: it cleaned the air of a 500-square feet room in a little more than an hour.

Considering the combination of this rate with considerably less loud fan operation at maximum speed, it is a great result. Indeed, Levoit has improved a lot the noise level of its more powerful models. To be sure, at maximum speed the noise is considerable (almost 55 dB), but at a suction power of this sort, anything less will come at a premium.

Something we missed in our previous picks was the lack of an automatic adjustment of the purifying operation based on air quality detection. Well, no reason to complain about this unit. Levoit LV-PUR131 is equipped with such an amazing feature, which not only ensures optimum air filtering, but also energy efficiency and cutting expenses on the replacement of the filters.

A great advantage of the Levoit LV-PUR131 is its ozone-free operation, ensured by the absence of ionic or UV-Light filter. Another one is its energy class. Designed for big households and large apartments and taking into account that it will probably operate for several hours each day, being rated as an A+ energy efficiency ensures that it will not prove a burden to your energy bills.

Last, we should mention the handy 12-hour timer, which affords great versatility to the use of the unit.

My only complaint, aside from the lack of portability (which is not really a problem), is the lack of smart-friendly features. I would really like to be able to control the unit through my table or smartphone. Levoit actually has recently launched a version of the LV-PUR131 (named LV-PUR131S) with Wi-Fi connectivity – offered though at a premium.

  • Great power
  • Ideal for large apartments and households
  • High filtering efficiency
  • Low noise levels
  • Energy efficient
  • Reasonably priced
  • Automated air quality detection and adjustment
  • Not so portable
  • No Wi-Fi connectivity

Our Opinion

Levoit LV-PUR131 offers a rather convincing combination of power, speed, energy-efficiency, reliability and relatively quiet operation that more than justifies its price. Its lack of Wi-Fi connectivity is certainly not a deal-breaker.

Design and Features

This is not a cheap Air purifier. Still, this does not mean that it is expensive. In our opinion, it is more than reasonably priced, after taking into account both its construction quality, efficiency and features.

First things first:  the unit arrives fully assembled except the filters (which are installed) must be unsealed and uncovered.

Philips AC3259/60 air purifier is a pretty large unit (70 x 35.5 x 24.5 cm) – understandably so since it is designed for rooms of almost 100 square metres. So, for its power, we would consider it compact. It comes with a solid plastic casing, and the elegant colour combination features in the 3000i series. Its castors make it easy to move around, while the six-feet wire affords you plenty of manoeuvrability.

All controls and buttons are on the top (On/off, Light on/off, Auto Mode, Fan speed, Timer and Reset/Child lock, plus a circular display), which is nice for the elderly or people that don’t wish to strain their backs.

Now, let us cut to what’s more important. The air filtering process relies on a three-filter system and the eminent AeraSense technology, which constantly monitors the air inside the room, adjusting the function of the unit and – the best of all – letting you know about it. As soon as you activated it, it will check the quality of the air and assess with a numerical value and a colour indication (blue for good, red for poor). We found this feature to be amazingly efficient and reliable. It could even a sense the entrance of a couple of sweaty kids around it, instantly altering its air quality assessment, which returned to normal only when the kids went and washed up!

Indeed, we do believe its claim of removing 99. 97% of ultrafine particles (PM2. 5), allergens, gases, bacteria and viruses – making it an invaluable ally for people with breathing problems and allergies.

As we would expect from an air purifier of this quality (and price), there is a timer, which allows you to operate the unit at will even when you are out of home, as well as a night mode, adjusting the settings (silent mode and with its lights off) in a way that will not disturb your sleep while keeping the air clean.

Note that the lack of a remote control is not an issue, since you can pair with your smartphone and control remotely from there.

  • Reliable, great construction quality
  • Smart tech-friendly
  • Value for money
  • Excellent efficiency
  • Great air quality monitoring
  • Not budget-friendly

Our Opinion

Sure, this is not a budget-friendly air purifier, but it is not an entry-level choice either. With advanced air filtering and air quality monitoring technology, exceptional design and the reliability of one of the greatest brands in the market, this is a truly excellent pick for people that wish something more from their air purifier.

Health Benefits of Air Purifiers

All houses contain harmful particles, posing a threat to human health even of the residents do not suffer from allergies. From shielding your respiratory system to enhancing your mood, air purifiers are indeed necessary for those among you that seek a healthy everyday environment.

  • They minimise asthma incidents, making them absolutely necessary for people suffering from asthma.
  • They eliminate allergens, the substances that cause and trigger allergic reactions and shocks, including dust and pet odour. Air purifiers that do not release ozone are even better.
  • They purge the air from tobacco and cigarette smoke, thus reducing the risk of developing some kind of lung disease and minimising secondary smoking. This is very important for children and elderlies, whose respiratory systems are very sensitive.
  • Air purifiers extract airborne asbestos particles, reducing the risk of developing mesothelioma., True, asbestos is now used any more in building materials, but old houses may have components with this poisonous They also eliminate radon gas, that causes lung cancer.
  • They also remove urban fumes and pollutants coming from outside, as well as carbon dioxide and the highly carcinogenic Volatile Organic Compounds (VOC).
  • Air purifiers also get rid of mosquitoes and other similar insects, often associated with dangerous infections.
  • Clean air improves mood levels, and air purifiers with ionisers are even more effective from this point of view. In addition, inhaling air free from pollutants alleviates stress.
  • Air purifiers produce gentle white noise, known to improve sleep

Air Purifier Buyers Guide

What exactly is an Air Purifier?

An air purifier is a device designed to clean the air circulating in a certain room or closed environment. It uses a filtering process targeting specific harmful or potentially harmful particles, including

  • pollen, plant spores and fungi;
  • dust, pet dander and hair;
  • mould spores, bacteria and viruses;
  • tobacco, cigarette and wood smoke;
  • household smells and odours;
  • toxins from pesticides;
  • VOCs (Volatile Organic Compounds), found in products such as paint, varnishes and cleaning supplies.

Why Should I Consider Buying an Air Purifier?

Aside from keeping the air around you as clean as possible, there are several other reasons that may necessitate the purchase of an air purifier, such as:

  • minimising allergic symptoms and incidents;
  • reducing asthma triggers;
  • ridding the air from dust;
  • eliminating mould;
  • reducing pet dander and hair;
  • removing or at least minimising smoke and all related odour.

What Types of Air Purifiers Are Available in the Market Today?

While there are numerous models and brands available in today’s market, they all fall into four basic categories, based on the filtration technology they use to clean the air around you.

  • High-Efficiency Particulate Air Filtration (HEPA)

HEPA is currently one of the most advanced air filtering processes, using a highly dense paper filter designed to trap airborne contaminants and a strong driving mechanism.

While numerous air filters use the HEPA sign, only the ones labelled with the phrase “True HEPA Filter” are worth your consideration, since they are the only ones certified as capable of removing 99.97% of all particles of at least 0.3 microns. The rest, using signed as “HEPA-type” or “HEPA-like” can only filter particles of 2-5 microns in size, which translates in a stunning 600% efficiency decrease.

Air purifiers with HEPA filtration technology are highly efficient and are considered the best possible option for people with respiratory sensitivity and severe allergies. On the other hand, they require regular filter replacements, which, sometimes are a bit pricey. Keep also in mind that they cannot rid the air from all unpleasant smells and chemical fumes.

  • Ionic Filtration

Ionic filtration emits a cloud of charged ions into the air, which in turn attach to airborne contaminants, thus adding weight to them and causing them to drop down to the floor or other intervening objects. Some models also make use of an electrostatic collection plate in order to attract fallen particles and remove them from the room.

The efficiency of ionic filtration is overwhelming; it can filter out particles as tiny as 0.01 microns! As an added advantage, they basically require zero maintenance and need no filter replacements. In addition, since they use no fan, they are much quieter.

On the other hand, the particles and pollutants remain inside the room (except in air purifiers equipped with an electrostatic plate), which means you will have to clean it thoroughly and frequently. Bear also in mind that they cannot remove odours, and they produce some ozone while operating, which is not the best thing for people suffering from asthma and other respiratory maladies.

  • Carbon Filtration

Carbon filtration uses a specific type of activated carbon consisting of numerous microscopic absorbent pores, designed to trap fumes, gases and odours – not particles though. Hence, carbon filtration is ideal for refreshing the air smell, not for purifying it. That explains their low price.

  • Ultra Violet (UV) Light

Last, we have air purifiers using ultraviolet light (the UV-C band in particular), which destroys pollutants instead of filtering them out. Note that the UV light is not emitted inside the room but within the air purifier. The band used is totally safe for humans but not for bacteria and viruses, since it destroys their molecular DNA structure, thus sterilising the air around you.

While capable of eliminating bacteria, viruses and germs, UV light air purifiers can only do that. They cannot remove particles. That is why UV light technology is often integrated within the air purifier with one of the other three filtering technologies.

Is There Any Other Type of Classification?

Yes, all air purifiers regardless of the filtration technology they use can also be classified in two “versions”, the Classic and the Smart Enabled ones.

  • Classic Air Purifiers

Classic air purifiers basically do the job without letting you know anything about the cleaning process. You just hear their humming and see the dirty filters and realise they are actually working. Certain models are equipped with air quality sensors, but again do not share any of these data with the user.

  • Smart Enabled Air Purifiers

As you have probably guessed, smart-enabled air purifiers are designed to share all sorts of data through a dedicated application in your mobile device or tablet. These data may include the specific pollutants that are being removed (for example pollen, hair or dust), and notify you of the current air quality. Naturally, smart-enabled air purifiers are a bit more expensive than the classic ones.

What are ACH and CADR Ratings?

These are two ratings commonly used in air purifiers specifications and is best to know what they mean before making your pick.

  • ACH (Air Changes per Hour)

Usually overlooked, the ACH rating actually tells you a lot about the air purifier’s efficiency. It reveals the number of times it can clean and refresh the air in your room every hour; a 5x rating, for instance, means that this specific device can clean the air in your room five times within 60 minutes.

Of course, the rating largely depends on the maximum surface (measured in square footage or square metres) the air purifier is designed to handle. If, for example, it is designed to manage a surface of 100 square metres, and your room is smaller, then its ACH rating gets even bigger. If, on the other hand, your room is bigger, than the actual number of air changes per hour will be smaller.

  • CADR (Clean Air Delivery Rate)

This rating reveals how well (not how many times) an air purifier cleans the air within a room of certain dimensions; it basically tells you about its effectiveness, and it is very useful when comparing air purifiers.

The CADR rating is measured using certain common pollutants, namely dust, tobacco smoke and pollen. Measurements usually range between 10-450 and are displayed in three consecutive numbers, for instance, 200/220/190. Naturally, the higher each number, the more effective the device is for this particular particle.

Unfortunately, not all air purifiers have a CADR rating on their specifications. Still, you should look for it anyway.

Choosing the Right Size of your Air Purifier

One of the most important specifications of an air purifier is its covered area. Make sure you check the square footage (or metre) rating of the air purifier that caught your eye and make sure whether it will meet your needs.

Additional Features

All models have some extra features, designed to augment efficiency and effectiveness as well as impress the consumer. The most common are:

Portability and Design Features

  • Digital Controls 

Digital controls can be found both in classical and smart-enabled air purifiers, allowing for more precise settings.

  • Adjustable Fan Speeds 

This feature is by now standard to all new models, which have 2-5 different fan speeds. More advanced models designed to clean the air faster than usual, also have a turbo speed mode.

  • Filter Replacement Indicators 

These also tend to become a standard feature. Filter replacement indicators basically notify you that the time has come to replace all or certain filters of the device. This is very handy since it ensures the proper operation of your air purifier. Otherwise, you would consume energy but still inhale unclean air.

  • Programmable Timer 

This feature allows you to deactivate the air purifier at a specific time or at a pre-set time interval – usually ranging from 2 to 8 hours. Saving energy and time, programmable timers are ideal for people that need their purifier to run even when they are out of home.

  • Handle & Casters

Obviously, for easier transportation. Some air purifiers with multiple filters and mechanisms can get quite heavy. Casters, on the other hand, add portability, enabling you to move the device around the room without lifting it.

  • Nightlight 

This handy feature allows you to locate the air purifier more easily in a dark room.

  • Remote Control 

  • Mobile App 

A standard feature for all smart enabled air purifiers, it affords you full control of all features of your air purifier through your smartphone or tablet, along with important data about the air quality and pollutants.

Filtration Features

  • Pre-filter 

Air purifiers with this feature have an extra filter designed to capture large particles, like hair or dirt and prolong the operational life of the rest of the filters, which are usually more expensive. The best thing about pre-filters is that they can be washed and reused, thus reducing maintenance cost even more.

  • Antimicrobial Treatment 

Antimicrobial treatment is actually a coating designed to prevent the accumulation of bacteria and microorganisms on internal filters. This feature not only improves the air quality but also prolongs the operational life of each filter.

  • Air Quality Sensors 

Designed to monitor the air for certain particles and pollutants, the air quality sensors constantly optimise the settings for more efficiency.

  • Plasma Wave Technology 

Plasma Wave Technology is an advanced ionisation method that uses water vapour instead of negative ions, making it even safer and ozone-free.

  • Photocatalytic Oxidation (PCO) 

This advanced filtering method is usually combined with UV Light technology. It oxidises chemicals and eliminates VOCs, bacteria, mould and fungi more effectively.

You Should Also Consider…

  • Maintenance Costs

Most air purifiers require some kind of maintenance to preserve their efficiency. Before getting impressed by an array of features, you should also check the corresponding maintenance cost, especially regarding filter replacement. As mentioned, ionic air purifiers are the most economical when it comes to maintenance, but this usually makes them more expensive to purchase.

  • Noise

Air purifiers produce some level of noise, and if you are light sleepers or a member of the family has trouble sleeping and wakes up easily, you should make sure the noise will not be a problem.

Naturally, air purifiers with adjustable fan speeds produce louder noise while operating in their top speed or turbo mode. However, you can probably use this speed during the day, so, better check the noise produced at the lower speed.

  • Energy Consumption

Most air purifiers consume around 5-200 watts, and models with Energy Star rating are preferable.

  • The Offered Warranty

Last, you should also check the warranty, that is the time span and issues it covers, thus avoiding issues with problematic components – which are always possible even with the most reputable manufacturers.

Remember, an air purifier is a device that you should be able to use for many years to come. It is nothing less than a small investment, aiming at protecting your health and the well-being of the people you love. It would be wise to devote some time to find the one that meets your needs and wishes.
