The Best Rated Air Purifiers
We have tested 133 HEPA air purifiers and share all our data on sound levels, energy usage and performance at different fan speeds.
Don’t get duped into buying an overpriced, under-performing air purifier.
Our current top pick is the Levoit Vital 200S because it offers the best performance for value. But you have options to consider, so read on and we’ll help you find the right air purifier for your home.

Levoit Vital 200S
Max room size (5 air changes per hour) : 390 sq.ft.
CADR (top speed) : 249 CFM
Helps with : Dust, allergens, smoke, odors, pet dander
Biggest pro : It outperforms units that cost twice as much.
Main highlights
The Levoit Vital 200S the air purifier I recommend for most people. And a big reason why that’s the case is the fact that you can buy it for less than $200 — and it regularly goes on sale, so you may find it as low as $149.
It also also offers excellent value, with enough CADR to clean medium sized rooms well at top and sub-45 dB speeds and pretty low running costs.
Plus, it comes with an onboard sensor, auto mode and one of the best apps I’ve tested, with new smart features being rolled out regularly.

Blueair Signature
Max room size (5 air changes per hour) : 645 sq.ft.
CADR (top speed) : 400 CFM
Helps with : Dust, pollen, smoke, odors, pet dander
Biggest pro : Excellent performance and doubles as a table.
Main highlights
The Blue Signature looks like a piece of furniture and also has the benefit of being another surface to keep things on.
Performance is top tier at both top speed and quiet fan speeds – to match this with a traditional air purifier you would need to spend a lot more and also have a much larger machine like the Coway Airmega Pro X or spend over $1200 with the IQAir Atem X.
Unlike previous Blueair models, this Signature model uses pelleted activated carbon and a decent amount.
Running costs are fair and whilst the initial price is higher than other mid size models on the market you do get a laser sensor something that is rare at this price point.

Winix 5510
Max room size (5 air changes per hour) : 373 sq.ft.
CADR (top speed) : 249 CFM
Helps with : Dust, pollen, smoke, odors, pet dander
Biggest pro : A budget unit with smart features and separate filters.
Main highlights
The 5510 is the next generation of the popular Winix 5500-2.
It provides a small package with a modern design with smart phone app support.
When testing it’s performance at sub 45 decibels it was able to clean our test room in 47 minutes at 40.8 dBA which was only 1 minute slower than our top pick (Levoit Vital 200S.)
The big benefit of the Winix 5510 is it’s non-bonded filter which mean that when your carbon runs out you can just remove it and still run your HEPA filter which can help reduce running costs.

Alen 35i
Max room size (5 air changes per hour) : 250 sq.ft.
CADR (top speed) : 162 CFM
Helps with : Dust, pollen, smoke, odors, pet dander
Biggest pro : Small size but still good air cleaning performance.
Main highlights
The Alen BreatheSmart 35i is quieter at top speed than every other small air purifiers we have bench-marked it against.
The laser sensor inside makes the auto-mode more responsive, more accurate and more useful than what you’ll get with other small air purifiers.
Alen offers a choice of 3 filters when you buy from Pure (Medical HEPA only), Advanced (includes pelleted carbon) and Ultimate (also includes a proprietary carbon catalyst designed for odors.)
Finally Alen has a lifetime warranty as long as you only buy Alen filters or have an active filter subscription.

AirFanta 3 Pro
Max room size (5 air changes per hour) : 529 sq.ft.
CADR (top speed) : 353 CFM
Helps with : Dust, pollen, smoke, odors, pet dander
Biggest pro : The most affordable high-CADR air purifier.
Main highlights
A air purifier with a CADR of 436 cfm for less than $150! If you had told me this before, I would have assumed it was some sort of scam.
But the AirFanta 3 Pro can provide multiple air changes to large rooms and for a initial price that is nearly 3 times cheaper than what you will normally pay with a standard HEPA retail device.
Whilst it’s not totally plug and play as you do need to fit the filters and put the fans in place, it’s much easier than a standard PC fan air purifier kit.
For those wanting to travel and bring along a high CADR device, there really isn’t anything else on the market to match this.

Austin Air HealthMate
Max room size (5 air changes per hour) : 169 sq.ft.
CADR (top speed) : 160 CFM
Helps with : Serious odors, chemical gases, VOCs, dust
Biggest pro : The best at removing VOCs thanks to 15 lbs of carbon.
Main highlights
While most standard air purifiers have small amounts of carbon in their filters, Austin Air packed their unit with a massive 15lbs of carbon and zeolite mix.
In our VOC test, the HealthMate was the most effective at removing gas pollutants from our grow tent among all the other air purifiers we tested.
Another thing that makes Austin Air unique is that they manufacture their devices at their factory in Buffalo, NY. So if you’re looking for an air purifier made in the USA, then this might be it.

CleanAirKits Luggable Ultra
Max room size (5 air changes per hour) : 472.5 sq.ft.
CADR (top speed) : 315 CFM
Helps with : Dust, pollen, smoke, pet dander
Biggest pro : The most energy efficient air purifier we've tested.
Main highlights
It achieves outstanding air cleaning performance with a relatively small footprint, it’s highly energy efficient, and is one of the most cost-effective devices to run in the long term, thanks to its use of PC fans and HVAC filters.
Sure, the design is very different from the usual cylindrical or boxy air purifier you might be used to seeing, the hardboard body isn’t as durable as plastic or metal, and it lacks smart features and other bells and whistles you find on traditional models.
But for those wanting to achieve the very best particle removal performance with low running costs, this is an incredible machine for less than $400.

Levoit Core 600S
Max room size (5 air changes per hour) : 562 sq.ft.
CADR (top speed) : 375 CFM
Helps with : Dust, pollen, smoke, odors, pet dander
Biggest pro : Durable, smart, high CADR and cheaper than $300.
Main highlights
After re-testing everything about this unit, I can confidently say that it can hold its own against newer models – especially when you consider its price.
The big standout benefit and a big win for existing owners has been the investment that Levoit has made to the app.
You now can adjust the way the Auto mode works, which was one of my main bug bears around auto-modes in general.
For those who value app connectivity and raw air cleaning power at a low initial price, then the Levoit Core 600S is well worth considering.

What to look for when buying an air purifier
The right air purifier will clean your air for years to come, but the wrong one will just waste your money. Read our tips before you buy.
Calculate the CADR needed for your room size
The higher the CADR (stated in CFM, or cubic feet per meter). the higher the air cleaning power. Use our CADR calculator to find out how powerful an air purifier needs to be based on the size of your space.
Choose the right filters for the job
If you've got hairy pets, look for a removable pre-filters. If you want to tackle allergens like dust, pollen and mold, you'll need a HEPA or MERV filter. And if you want to remove odors and chemical gases, you'll need pelleted carbon.
Factor in how noisy the air purifier will be
For quiet rooms like a home office or a bedroom, you'll want an air purifier powerful enough to clean the air while generating less than 45 dBA. Read our full reviews to find out if the model you're considering is a good option for your quiet space.
Calculate the long-term running costs
Your air purifier will need its filters replaced eventually, so take your time to find out how much the replacements will cost you over a year. There are models that will be cheap to buy but expensive to run!
Consider if you need smart features or an app
Special features like smart functions, app connectivity, onboard air quality sensors or remote controls are handy perks that can make life easier. However, you shouldn't sacrifice CADR or performance over nice-to-have features - if your budget is tight, drop the fancy functions.
