The Blueair ComfortPure 3-in-1 improved my breathing inside my home and helped clear my room from wildfire smoke late last year.

As an asthmatic, I know the air quality is ideal when I'm not regularly coughing or sneezing indoors. On the flip side, if my sinuses act up when I'm home (but seem to be fine otherwise), then there's a good chance that the air around me could use some attention. A good first step to address this is to use an air purifier. These fundamentally simple appliances not only trap airborne allergens like dust mites, pollen, and even bacteria, they remove smoke and other unpleasant odors from the air. In my home, the is the saving grace that frees me from all of the above. Most air purifiers on the market solely focus on filtering airborne particles and toxins. But as the product name implies, Blueair's "3-in-1" does more than your average air filter. Along with keeping my air quality in tip-top shape with its boosted purification setting, it also has cooling and heating, both of which have come in handy when facing New York City's unpredictable weather head on. The Blueair ComfortPure also features a proprietary HEPA filter which uses electrostatic and mechanical filtration technology to automatically detect and remove 99.8 percent of airborne pollutants. According to the company, air is filtered faster and more quietly than the average HEPA filter. The unit I have is recommended for spaces up to 175 square feet. My room is about 85 square feet and I can attest that the air is noticeably clearer within an hour. As for the noise, the unit is 24 dB on the lowest setting—that's whisper-quiet—and 52 dB on high, about as loud as a low refrigerator hum. The model I own launched in October 2024 and I received mine pretty soon after its release. So, as one of the first to experience the Blueair 3-in-1, I have a pretty solid idea of how well it works. There's lots I appreciate about it, but there are also some drawbacks…
