Best Small Room Air Purifier

Best Small Room Air Purifier – A great air purifier for  small room can really improve your life—reducing allergens such as pollen and mold spores, and protecting against wildfire smoke and other kinds of smoke.

But to qualify as great, an air purifier needs to be powerful enough to clean the air in a large living room or playroom, quiet and dark enough for you to sleep near it in a bedroom, and inexpensive enough that it’s reasonable to have several spread throughout your home.

ROUND UP

1.Coway Airmega AP-1512HH

Within 30 minutes, the Coway AP-1512HH Mighty reduced heavy smoke pollution in a 135-square-foot, 1,215-cubic-foot New York office by as much as 99.6%. In past tests, it performed equally well in a 200-square-foot, 1,600-cubic-foot New York City bedroom.

And when we tested it during ongoing smoke conditions in a vast Los Angeles conference room of nearly 10,000 cubic feet—more than twice as large as the Mighty’s specs would seemingly allow—it cut particulate pollution by almost 70% in an hour. It’s a great value, at an up-front price often lower than $200 (and about $470 over five years, adding in electricity and replacement filters).

Pros & Cons



2.Winix 5500-2

The Winix 5500-2 is an exceptional performer on particulates, capturing 99.9% of the smoke in our test room in just 30 minutes on high and 97.2% on its medium-high setting, where it emits an easy-to-live-with 40 decibels. In both cases, that’s a bit better than the results we got from the Coway AP-1512HH Mighty, though in practice the differences are insignificant:

Both machines, when used continuously as they are in most homes, will drop particulates to near zero in under an hour—and keep them there. We still prefer the Mighty for its lower energy consumption, smaller visual footprint, display-shutoff feature, and more attractive look, but it’s a close race.

Pros & Cons



3.Winix AM90

Another Winix, the AM90, uses the same HEPA filter as the 5500-2 and delivered virtually identical performance in our testing. It has a more contemporary design that many people are likely to find more attractive (if you prefer white—the only color option).

It adds Wi-Fi capability and a rudimentary app, and it typically costs a few dollars more than the 5500-2. The almost identical Winix AM80 lacks the AM90’s Wi-Fi capability and comes only in dark gray.

Pros & Cons



Most Honorable Mentions in the post

4.Blueair Blue Pure 311

The Blueair Blue Pure 311 Auto is similar in capabilities to the Coway AP-1512HH Mighty and the two Winix models. It reduced smoke levels by 99.9% in 30 minutes on high and by 94.2% on medium. Its auto function, which Blueair introduced to the Blue Pure lineup in late 2020, monitors your room’s air quality and adjusts the fan speed accordingly.

And it has other features we like, including notably quiet performance, terrific energy efficiency, and a control panel that automatically dims after you adjust the settings. This model is also particularly attractive, with a tweedlike, washable cover that’s available in several muted colors (it arrives in gray; you can purchase the other colors separately).

Pros & Cons



5.LEVOIT Air Purifiers

Levoit’s Core 400S offered solid performance in our testing, removing 99.1% of smoke particles in 30 minutes on high and 96.3% on its third of four speeds—the highest at which it produces less than 50 decibels of noise.

If you want a basic smart air purifier, it’s an attractive option, as it connects with Amazon Alexa and Google Assistant for voice control, in addition to having its own app. But it’s typically more expensive than our top pick, the Coway Mighty, up front.

Pros & Cons



6.Holmes Desktop

You’d be forgiven if you gave this a quick glance and mistook it for a clock or radio, but this air purifier’s slim design makes it suited perfectly for desks and other workspaces, whether you need it to sit horizontally or vertically to accommodate laptops or other belongings.

Mold, smoke, bacteria, pet dander and other contaminants are no match for the powerful HEPA filter and ionizer duo, working in tandem to keep the air from being dirty and stale.

Pros & Cons



7.Molekule Air

This mini air purifier by Molekule may be significantly more expensive than the others mentioned on our list, but that’s because it’s more powerful. By using a process known as Photochemical Electrochemical Oxidation (PECO) nanotechnology to destroy contaminants in the air. In short, instead of trapping things like dust, mold and viruses, this air purifier actually destroys them.

But don’t worry, you don’t have to be Bill Nye the Science Guy to use this; in fact, this air purifier’s settings are extremely customizable.

Pros & Cons



WRAP UP

Best Small Room Air Purifier –  Strong as the Mighty is, its performance is not as singular as it once was, and in recent years many other machines have closely approached our high standards.

If you prefer the looks, cost, or other features of our also-great picks, know that they match the Mighty in purifying performance.
