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 Coway AP1512HH. It uses a four-stage filtration process to effectively and efficiently clean your air – plus it’s portable, quiet and one of the cheaper models to run too. 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
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.

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 low 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.

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.

The Rabbit Air MinusA2 is the most efficient air purifier we looked at, it only uses are 62 watts while running. It also has a unique aesthetic that makes it more attractive than the competition. The low energy consumption of the MinusA2 means it won't affect your electricity bill too much. However, this unit's mobile app controls make it an expensive product at nearly $600.
There are six cleaning stages that clean air in rooms up to 300 square feet, which is lower than average, but sufficient for most rooms in a home. The filters aren't as effective as with more affordable units, which is disappointing. A built-in air quality sensor 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. It's more expensive, but this is one of the best air purifiers out there.

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.
