Best Air Purifier for Small Bedroom

Best Air Purifier for Small Bedroom – According to the EPA, we spend up to 90% of our time indoors (alongside the 2x to 5x more polluted air than outdoors). At least 8 hours per day is spent in the bedroom (if we’re lucky). That’s why bedroom air purifiers are the ones most people want to get.

All air purifiers can be placed in the bedroom, but not all air purifiers are best equipped to be bedroom air cleaners.


1.Coway Airmega AP-1512HH

After a sixth round of testing, encompassing 47 different air purifiers and more than 200 hours of lab and real-world trials, the Coway AP-1512HH Mighty remains our pick as the best air purifier for most people. It has kept its place for so long for many reasons. In raw performance, it stands among the best purifiers we’ve ever tested, achieving as much as 99.1% removal of airborne particulates in just 30 minutes in our latest test—and that was on year-old filters. It has maintained its high performance for years:

We’ve tested the same machine four times starting in 2017, and it has always delivered similar results. The Coway Mighty is also unusually easy to live with, as it’s quiet and compact, and its display can go dark at night, making it a good fit for master bedrooms, playrooms, and living rooms or dens. Finally, it’s easily the most affordable purifier of its capabilities we’ve ever found: Adding up the purchase price, the costs of 24/7 operation on medium, and the costs of annual filter changes, you’re looking at about $470 over five years. (Or less: We calculate electricity costs at New York’s rates, which are 50% above the national average.)

Pros & Cons

2.Winix 5500-2

The Winix 5500-2 is a direct competitor to the Coway AP-1512HH Mighty, as it has a nearly identical clean air delivery rate (CADR) and offers 5.1 air changes per hour (ACH) in a 350-square-foot space. Most important, it performed just as well as the Mighty in our testing. In fact, it did a bit better: In our October 2020 test, on brand-new filters, it removed 99.9% of 0.3-micron smoke particles when set on high. On medium, it removed an impressive 97.3%.

The Mighty, on year-old filters, removed 99.6% and 89.2%, respectively—in line with all our past test results, on new or old filters. Currently the 5500-2 is also cheaper than the Mighty. It’s not our top pick for several reasons: It’s larger and (to most eyes) not as attractive, it lacks a display-shutoff feature except when it’s on its lowest fan setting, and it draws more electricity, contributing to slightly higher running costs. But simply put, the Winix 5500-2 is an impressive purifier.

Pros & Cons

3.Blueair Blue Pure 311

The Blueair Blue Pure 311 Auto is another stellar purifier. It’s from the same company that makes our large-space pick and uses the same technology, combining a non-HEPA (but very efficient) filter with a system that imparts an electrical charge to any particles that pass through, helping them stick to the filter the next time around—essentially through static cling.

On high, it reduced a heavy load of 0.3-micron smoke particles by 99.9% in 30 minutes; on medium, it reduced them by 94.2%. Both results indicate that it’s a highly efficient purifier, in the same league as the Coway AP-1512HH Mighty and our Winix picks. In a 350-square-foot room, it can deliver 5.3 air changes per hour (ACH) based on its CADR measurements, nearly identical to the results from the Coway Mighty and slightly more than what the Winix models can achieve.

4.LEVOIT Air Purifiers

A compact purifier similar in performance to the Coway AP-1512HH Mighty and our other also-great picks, the Levoit Core 400S adds voice control via Amazon Alexa or Google Assistant, along with remote manual control through an app.

Although most people are likely to be well served by purely manual or basic automatic purifiers (those that have a built-in air-quality sensor and adjust to changing conditions), if you are an avid smart-home proponent, or if mobility, dexterity, vision, or other issues make it difficult for you to adjust appliances, the Core 400S is a highly capable and relatively affordable option.

5.Alen 45i Air Purifier

Alen BreatheSmart is the only dedicated series of air purifiers, specialized to be used in bedrooms. It’s made by Alen, one of the most reputable companies in the air purification industry. The 45i model is the best BreatheSmart unit and it’s easy to see which is the best bedroom air purifier.

Specs-wise it’s obvious that if you would set your engineers to design air purifiers specifically for bedrooms, they would come up with a silent, 200+ CADR rated, HEPA filter air purifier for a standard-sized bedroom. Alen BreatheSmart 45i is all that.

Pros & Cons

6.HATHASPACE Air Purifier

Hathaspace HSP001 has an extensive 5-stage filtration. In addition to the basic 3-stage filtration (pre-filter, activated carbon, and HEPA filter), the Hathaspace HSP001 has a secondary pre-filter as well as a cold catalyst filter for the last stage filtration.

A secondary pre-filter is especially useful if you have pets. Cats and dogs will leave pet dander, fluff, and all kid of hair all over the bedroom. Pre-filters are designed to catch these larger airborne particles. You can read an in-depth review of Hathaspace air purifiers here.
