If you’re looking for the best air purifier for your home or office that you can buy, you’ve come to the right place. We’ve tested all the top models – at a range of different prices – to help you find the best air purifier for your budget.

We spend a lot of our time indoors. But the air inside might not be as clean as you think. Allergens and dirt can cause health problems, with typical indoor pollutants including pollen, dust, mold or fungi spores, bacteria, cigarette smoke, fumes from cleaning products, and volatile organic compounds (VOCs) from things like your carpet, furniture or paint.  

A good air purifier will quickly clean your air, removing harmful pollutants and increasing the overall pleasantness of your environment. Whether you’re looking for an air purifier for allergies or smoke, you have pets, or you live in an area with polluted outdoor air – or, indeed, for any other reason – we’ve got you covered in this guide.  

What’s the best air purifier?

We think the best air purifier you can buy right now is the Rabbit Air MinusA2. It uses a six-stage air filtration system to effectively and efficiently clean your air – plus it’s quiet and has a long filter lifespan. The right air purifier for you, though, will depend on why you want it, and the size of the room you need to purify. 

Check the room coverage stats and filter type before investing in a model. Ideally, you want a True HEPA Filter: these capture 99.97% of all allergens, virus particles, pollen, mold and fungi particles down to 0.3 microns. A carbon filter will reduce odors, smoke and chemical vapors – great for open-plan kitchen/diners, or rooms with log burners – while an ionizer will help suck in the tiniest pollutant particles. 

Finally, the best air purifiers for allergies – or if you have pets in your home – will be good at removing pet dander (flecks of skin shed by cats, dogs, rodents, birds and other animals with fur or feathers). Here's our pick of the best air purifiers you can buy right now.

The best air purifiers for your home or office

1. Rabbit Air MinusA2

Exceptionally quiet, efficient and versatile, we think this is the best air purifier you can buy

Filters: 6 - including pre filter, True HEPA filter, carbon and pet filters | Ionizer: Y | Auto mode: Y | Power consumption: 7-61W | Noise: 20.8-51.3 dB | Warranty: 5 years | CADR: pollen removal - 200, dust - 193, smoke - 180 | Coverage (sq ft): 700-815

Very energy efficient
Handy change filter indicator
Great for houses with pets
Expensive

The Rabbit Air MinusA2 is one of the best air purifiers you can buy, with great performance and plenty of smart features. That isn’t surprising: Rabbit Air is one of the leading companies in the air purifying industry. But it is impressive. Firstly, it's the most efficient air purifier we looked at: it only uses 62 watts while running, so it won't affect your electricity bill too much. It also has a unique aesthetic that makes it more attractive than the competition. 

This air purifier is suitable for rooms up to 300 square feet, and comes with a six-stage air filtration system, making it particularly great for allergy and asthma sufferers. The Rabbit Air MinusA2 also has a built-in air quality sensor, which means this unit works automatically and informs you when the filters need to be replaced. 

You can mount this air purifier on the wall, which is unique among the products we reviewed. Furthermore, Rabbit Air lets you choose from a variety of artwork for the front panel, effectively turning the unit into a decoration that doesn't detract from your home's décor. At nearly $600, it's more expensive, but the Rabbit Air MinusA2 is easily one of the best air purifiers out there.

best air purifier: Honeywell HPA300

2. Honeywell HPA300

A competitively priced air purifier with no extra features but great filtering capabilities and a five year warantee

Filters: 2 - pre-filter, HEPA filter | Ionizer: N | Auto mode: N | Max power use: 127W | Noise: 63 dB | Warranty: 5 years | CADR: pollen removal - 300, dust - 320, smoke - 300 | Coverage (sq ft): 465

Excellent filter effectiveness
Five-year warranty
Simple design
No timer, sleep mode or remote
No ionizer

When it comes to value for money, we consider the Honeywell HPA300 to be the best air purifier right now. Despite retailing for less than many rival systems, the HPA300 delivered an impressive Clean Air Delivery Rate (CADR) in our tests. The Honeywell HPA300 is also effective in rooms up to 465 square feet, circulating the air once every 12 minutes (which is five times every hour). It was the second most powerful air cleaner we tested.

As you would expect, this air purifier’s lower price does mean that it isn't as feature-packed as other units. (For example, it doesn't have an auto mode, shut-off timer or remote control.) However, if you want good core functionality and a generous five-year warranty at a very competitive price, then the Honeywell HPA300 is one of the best air purifiers out there.

best air purifier: Dyson Pure Cool (TP04)

3. Dyson Pure Cool Tower purifying fan (TP04)

A powerful air purifier with voice control that doubles as a fan

Filters: 2 - Sealed HEPA filter and activated carbon filter | Ionizer: N | Auto mode: Y | Max power use: 52W | Noise: 62.2dB | CADR: pollen removal - none provided | Coverage (sq ft): 500

 Well-respected brand 
 Great air quality feedback 
 Fan functionality 
Expensive
No ionizer

The Dyson Pure Cool offers a plethora of feedback about your air quality through its LCD display and its accompanying app. It covers overall air quality, temperature, humidity and reports on four specific particle types so you can monitor what activities cause the levels to fluctuate. In auto mode, the air purifier will automatically adjust its filtering power according to the air quality it detects, making it very efficient.

Its 350 degrees of oscillation, which you can also control via the app, allows you to direct the airflow and intake for greater control of air purification.

The other big feature of this air purifier is that it doubles up as a fan. Set to forward airflow, it will circulate cool air as it purifies, while switching to a backwards airflow effectively turns off the fan functionality.

Air Purifier: Blue Air Pure 211+

4. Blueair Blue Pure 211+

A stylish air purifier with the power to clean large rooms

Filters: 3 - Pre-filter, particle filter and activated carbon filter | Ionizer: N | Auto mode: N | Max power use: 60W | Noise: 56dB | CADR: 350 Dust 350 Smoke 350 Pollen | Coverage (sq ft): 540

Great room coverage
Good CADR rating
Well built
No true HEPA filter
No sensor

The Blueair Blue Pure 211+ is a well-designed air purifier, made for large rooms, with great purification performance. It’s 3 stage filter system doesn’t include a True HEPA filter, which is quickly becoming the standard for air purifiers, but it does include its own particle filter that uses HEPASilent technology to combine mechanical and electrostatic filtration, still capturing minute particles.

Combined with 360 degree air intake and its powerful motor, the Blueair Blue Pure 211+ is an air purifier that performs brilliantly and has the CADR ratings to back it up.

It is a relatively expensive system, which means its lack of air quality sensor and auto mode is disappointing, but it's still a great air purifier that shouldn’t be overlooked.

Best air purifier: Winix HR900

5. Winix HR900

The best air purifier for pet owners

Filters: 5 - Ultimate Pet Pre-filter, pre-filter, Activated Carbon filter, True HEPA filter, Winix PlasmaWave ionizer | Ionizer: Y | Auto mode: Y | Max power use: 46.6 watts | Noise: 55.2 DB | CADR: 194/200/220 (smoke/dust/pollen) | Coverage (sq ft): 300

5 step cleaning system
Quiet
Air quality indication
Small room coverage
Low airflow in sleep mode

We think the Winix HR900 is the best air purifier for pet owners. Larger particles, such as pet hair and dander, tend to be a particular problem when you share your home with pets. Most air purifiers tackle these particles with a pre-filter, which also helps protect the more delicate inner filters, but the Winix HR900 has two prefilters including an Ultimate Pet Pre-filter for an extra layer of protection against pet-related dust and dirt.

Its color-coded system of lights offers real-time feedback on your air quality at a glance and in auto mode it will automatically adjust the fan speed, ramping up when poor air quality is detected and dropping down to save energy when air quality is good.

 best air purifier: Coway AP1512HH

6. Coway AP1512HH

This lightweight, portable air purifier is very energy efficient

Filters: 4 - pre-filter, odor filter, True HEPA filter, Vital Ion | Ionizer: Y | Auto mode: Y | Max power use: 79W | Noise: 58.3 dB | Warranty: 3 years | CADR: pollen - 240, dust - 246, smoke - 232 | Coverage (sq ft): 360

Lightweight and portable
Energy efficient
Automatic filter controls
No sleep mode
Shorter warranty than competition
Air filtering could be a little better

The Coway AP1512HH is an excellent all-round air purifier, delivering fresh, clean air, while remaining portable – and it's competitively priced too. It has an effective four-stage filtration process, with a washable pre-filter for large particles, and a carbon filter that catches odors. There's also a HEPA filter to suck in tiny particles like cigarette smoke and pollen, while the final fourth stage is an optional ionizer. 

The Coway AP1512HH is quiet, producing just 58dB of sound. It comes with an auto mode that automatically detects the quality of the surrounding air and operates accordingly, plus it boasts an Energy Star certification, meaning it's energy efficient. The AP1512HH also comes with a decent (if not generous) three-year warranty and weighs just 15 pounds, making it highly portable..

This combination of effective purification, portability and energy efficiency, along with a very affordable price, makes the Coway AP1512HH one of the best air purifiers you can buy – whatever your reason for wanting one.

best air purifier: Whirlpool Whispure

7. Whirlpool Whispure

The best air purifier at filtering pollutants – but it's heavy than others

Filters: 2 - carbon filter, True HEPA filter | Ionizer: N | Auto mode: N | Max power use: 102W | Noise: 55.1 dB | Warranty: 5 years | CADR: pollen removal - 401, dust - 325, smoke - 316 | Coverage (sq ft): 490

Exceptionally effective filter
Quieter than competition
Five-year warranty
No automatic filter controls
Not as energy efficient as top pick
Heavier than other models we tested

If you’re looking for a filtration powerhouse capable of handling even large rooms with ease, the Whirlpool Whispure AP51030K is one of the best air purifiers you can buy. (And, when we say large, we mean large: the AP51030K can handle rooms up to 490 square feet in size.)

The Whispure’s Clean Air Delivery Rate (CADR) is the highest of any air purifier we’ve tested here at TopTenReviews, meaning that it removes smoke, dust, pollen and more from indoor air with ease. If air quality is the sole aspect you're interested, we'd strongly recommend this model.

It isn't light, weighing in at 20 pounds – so it's less portable than the other options on this list. But if you think that means lots of noise, think again. As we discovered, the WAP51030K only produces 55 decibels (dB) of noise on its highest setting. It's an excellent choice of air purifier.

best air purifier: Kenmore 83396

8. Kenmore 83396

Another very good air purifier at a lower price

Filters: 2 - pre filter, HEPA filter | Quiet mode: N | Ionizer: Y | Auto mode: N | Max power use: 101W | Noise: 62.4 dB | Warranty: 1 year | CADR: pollen removal - 251, dust - 229, smoke - 205 | Smoke removal: 205 | Coverage (sq ft): 318

Good for smaller rooms
Cheaper
Less effective filtering than some

The Kenmore 83396 doesn't have the same filtering performance as larger air purifiers, but it's an excellent and affordable option for rooms up to 318 square feet. It has lower CADR scores and a lower number of air changes per hour than most of the other air purifiers we reviewed, though you can offset these deficiencies by using the unit in smaller rooms. 

The Kenmore 83396 only weighs 17 pounds, making it one of the lightest and most portable air purifiers that we reviewed. This means you can move it between rooms without much trouble. Although it's not particularly efficient compared to the competition, this unit does have an Energy Star certification, which makes it better than many cheaper units on the market. There are only basic timer settings, which means you don't get sleep or automatic modes, but this simplicity helps make the unit easier to use. The one-year warranty is disappointing compared to the five-year warranties we found on most of the units we reviewed.

How to buy the right air purifier for you

When buying an air purifier the most important question you need to ask yourself is what exactly do you want the system to do? Specific air purifiers, often because of how they have been designed, are expert at certain types of purification, while others have a focus on cleaning specific room sizes.

For example, if you have pets in your home and have one or more family members who suffer from allergies, then you should probably be looking for an air purifier that scores well in the removal of pet dander (flecks of skin shed by cats, dogs, rodents, birds and other animals with fur or feathers).

Equally, if you’re looking to outfit an open-plan kitchen-diner apartment then you should be looking for a different air purifier than if you are trying to clean the air in a house bedroom - after all, you’re going to want to consider smoke in the former far more than in the latter.

Obviously, price and portability are also factors to consider. Here at TopTenReviews we think you should be ideally looking to spend a couple hundred dollars on an air purifier if you can, however that doesn’t mean you should discredit models that are cheaper or more expensive, either. Evaluate what you need and what you can spend, do your research, browse the best air purifiers going, and then pull the trigger - by following this course we’re confident you’ll find the perfect air purifier for you.

What are the best air purifier makers?

Naturally, the maker of our all round best air purifier, Rabbit, makes the list of top makers. However, there are plenty of other great air purifier brands in business today, including: Whirlpool, Honeywell, Winix, Philips, Coway and Dyson. These air purifier makers have proper pedigree and heritage, as well as a track record of reliability and quality in terms of product testing here at TopTenReviews.
