After eight years, during which we’ve checked 47 different air purifiers, we believe the remarkable Coway AP-1512HH Mighty is the best air purifier for allergies among them– as we have since 2015.

Our pick
Coway AP-1512HH Mighty
Reliable, efficient, and inexpensive
Perfect for rooms, game rooms, and living areas, the Mighty is one of the best-performing, most long lasting, as well as many cost-effective purifiers we have actually checked.

Within half an hour, the Coway AP-1512HH Mighty lowered hefty smoke contamination in a 135-square-foot, 1,215-cubic-foot New York workplace by as much as 99.6%. In previous examinations, it carried out just as well in a 200-square-foot, 1,600-cubic-foot New York City room. As well as when we checked it during continuous smoke conditions in a huge Los Angeles meeting room of nearly 10,000 cubic feet– more than two times as huge as the Mighty’s specifications would apparently permit– it cut particle contamination by almost 70% in an hour. It’s an excellent worth, at an up-front cost often lower than $200 (as well as about $470 over 5 years, including electrical energy and also replacement filters). The Mighty’s compact kind, quiet operation, as well as ability to shut off its display lights make it particularly well suited to rooms. In long-term usage, we’ve repeatedly validated that it performs like new despite having filters used continuously for a year or longer.

Coway Airmega 200M.
Various appearance, exact same piece de resistance.
The 200M and the Mighty are basically similar in performance, yet the 200M has an appearance that you might like, and also it’s a good option if you discover it at a reduced cost.

$ 230 from Coway.
The Coway Airmega 200M is made by the exact same business as the AP-1512HH Mighty as well as is basically identical to that version in every crucial respect, namely the controls, noise, and performance. Their filters as well as also their faceplates are compatible. And like the Mighty, the Airmega 200M has a display-shutoff function that allows you dim its lights, something we value extremely for bedroom use. The Airmega 200M has a square grille as opposed to a round one– but that’s the only major physical difference. If you choose the Airmega 200M’s appearances or if you discover it at a much better cost, we suggest it just as highly.

Likewise terrific.
Winix 5500-2.
Extraordinary efficiency, brutalist layout.
The Winix 5500-2 is a phenomenal performer, however its raw look, absence of a screen shutoff, and also slightly greater electrical usage are (small) shortcomings.

$ 160 from
The Winix 5500-2 is a remarkable performer on particulates, recording 99.9% of the smoke in our examination space in just 30 minutes over as well as 97.2% on its medium-high setup, where it discharges an easy-to-live-with 40 decibels. In both cases, that’s a bit better than the outcomes we obtained from the Coway AP-1512HH Mighty, though in practice the differences are irrelevant: Both devices, when utilized continually as they remain in most houses, will certainly go down particulates to near zero in under an hour– as well as keep them there. We still prefer the Mighty for its reduced power intake, smaller sized aesthetic footprint, display-shutoff attribute, as well as extra eye-catching look, yet it’s a close race.

Likewise fantastic.
Winix AM90.
Remarkable efficiency, contemporary style.
Essentially a 5500-2 in a sleeker housing, the AM90 also shares that version’s few drawbacks, particularly no display screen shutoff as well as greater power consumption.

$ 209 from
An additional Winix, the AM90, uses the exact same HEPA filter as the 5500-2 and delivered essentially similar performance in our screening. It has a much more contemporary style that lots of people are most likely to discover extra appealing (if you favor white– the only shade option). It includes Wi-Fi capacity and also a rudimentary application, and it commonly costs a couple of bucks more than the 5500-2. The almost the same Winix AM80 lacks the AM90’s Wi-Fi ability as well as comes just in dark grey.

Also fantastic.
Blueair Blue Pure 311 Vehicle.
Blueair Blue Pure 311 Car.
Top efficiency, pleasing kind.
Delivering phenomenal performance in an appealing type, the Blue Pure 311 Auto endures only from a lack of a screen shutoff as well as higher running costs.

$ 250 from Amazon.
The Blueair Blue Pure 311 Vehicle is similar in abilities to the Coway AP-1512HH Mighty and the two Winix versions. It reduced smoke degrees by 99.9% in half an hour above and also by 94.2% on medium. Its automobile feature, which Blueair presented to the Blue Pure lineup in late 2020, checks your room’s air top quality and adjusts the follower rate as necessary. And also it has various other attributes we like, including significantly silent performance, great energy effectiveness, and also a control board that automatically dims after you readjust the setups. This design is likewise especially appealing, with a tweedlike, cleanable cover that’s readily available in numerous muted shades (it shows up in gray; you can acquire the various other shades independently). Two minor knocks against it: The air-quality indicator light, a bright blue LED, turns off only when the device is on its slowest setup, and also Blueair recommends replacing the filters every six months, pushing annual expenses to $80 (versus concerning $50 for the Coway as well as Winix models).

Also wonderful.
Levoit Core 400S.
Levoit Core 400S.
Piece de resistance plus voice control.
As effective as our leading pick, the Coway Mighty, however usually a bit more pricey to run, the Levoit Core 400S includes voice control via an application, Alexa or Google Aide.

$ 189 from
Levoit’s Core 400S provided strong efficiency in our screening, eliminating 99.1% of smoke particles in thirty minutes on high and also 96.3% on its third of 4 speeds– the highest at which it creates less than 50 decibels of sound. If you desire a fundamental smart air purifier, it’s an attractive choice, as it connects with Amazon Alexa and also Google Aide for voice control, along with having its very own application. But it’s typically a lot more expensive than our top choice, the Coway Mighty, in advance.

Update choice.
Blueair Blue Pure 211+.
An excellent entertainer for bigger spaces.
The Blue Pure 211+ aced our examinations, and its capability to move incredibly high volumes of air makes it our pick for large rooms.

$ 320 from
$ 320 from Home Depot.
$ 300 from Bed Bathroom & Beyond.
The Blueair Blue Pure 211+ is our selection among air purifiers for large rooms of up to 650 square feet, particularly when the space entails open layout or high ceilings. With the ability to filter extra air per hr than our leading choice, the Coway Mighty, it works much faster to achieve and also keep reduced particulate degrees in such challenging rooms. The up-front cost and also running costs of heaven Pure 211+ are much higher than those of the Mighty (totaling regarding $1,150 over five years), yet that’s comparable to the expenses of many other large-space purifiers we have actually checked out. It was a phenomenal entertainer in our testing, as well as it’s quiet and appealing too. All that said, unless you truly require to clean a specifically huge room, the quieter, smaller, and extra economical Coway Mighty is typically a better option.

Budget plan choice.
Levoit Core 300.
Levoit Core 300.
Small, efficient, and also attractive.
In a small bed room, dormitory, or office, the compact and affordable Levoit Core 300 does very well as well as looks great.

$ 100 from Amazon.
$ 100 from Residence Depot.
If you need to clean up the air in a space of about 200 square feet, the Levoit Core 300 is a solid as well as low-cost purifier. It was impressive in our tests, lowering particulates by more than 97% on its high setting in thirty minutes in a 135-square-foot New York City office. On tool, it reduced them by greater than 92%. It’s eye-catching and portable, gauging just 14 1/2 inches tall as well as 8 1/2 inches in diameter, and also its display-shutoff attribute means it won’t interrupt sleep with intense lights. At around $100 to buy, it’s also the most affordable in advance of all our choices. But it’s not extremely power effective: Running it 24/7 on tool eats regarding $300 of electrical power over 5 years, and also 7 brand-new filters in that period set you back $180, making this design somewhat a lot more costly than the Coway Mighty over the long-term. And also it doesn’t equal the Mighty or the Blue Pure 211+ in larger areas.
