Honeywell’s True HEPA Air Purifier uses an activated carbon pre-filter to help capture large airborne particles and reduce odors and VOCs. The filtration helps capture up to 99.97% of the following microscopic airborne allergens and particles: Dust, pollen, pet dander, dust mite debris, and smoke. It has three cleaning levels (high/medium/low) with a turbo setting that is supposed to be excellent for people with allergies, so essentially our entire household. I especially appreciate the silent operation and dimmer option, this is critical in the evenings.
The bottom line: Honeywell is an OG air purifier and air conditioner brand, I would highly recommend any of their products. Did I forget to mention that they offer a five year warranty? Doesn’t get classier than that. Also, this model earned the ENERGY STAR label by meeting strict energy efficient guidelines set by the U.S. EPA so seems pretty legit! The Gore family swears by it, what other approval do you need?

My space: I’m always looking for ways to protect myself from anything that could flare up my eczema and dust allergies, but once pollen gets thrown into the mix, all bets are off. While I do a pretty good job of catching the visible aggressors with dusting and vacuuming around my house, it’s difficult to monitor microscopic allergens and airborne contaminants, so I’m usually left sniffling or itching during transitional seasons.
Area coverage: Dyson’s Purifier Hot+Cool is great for medium to large rooms and can easily cover an area of up to 315 square ft (2860 cubic feet) if not more, according to tests conducted by Dyson. I kept mine in my bedroom, which is about 170 square feet.
Filter replacements: Filter replacements run about $80 from Dyson, though cheaper alternatives do exist from outlets like Amazon (just know these off-brand versions have been reported to work to varying degrees). The filters easily snap into the chamber-like base of the purifier and Dyson recommends replacing your filters when you’re alerted by the app or every 12 months, whichever comes first.
My experience: In addition to a small remote control, there’s also the Wifi-enabled Dyson Link app, which you can download to your smart device. I usually detest having to download an app to get the most out of my tech and appliances, though the Link app made setup a breeze; plus, if you own more Dyson home products it’s easy to manage them all in one place.
The purifier itself works like a dream, and I noticed within a week of use that I felt noticeably less congested. The intuitive device uses a 360° filtration system that implements a combination of activated carbon to remove potentially harmful gases and odors from the air and a HEPA H13 filter to capture 99.97% of particles. I appreciated that the Hot+Cold has an auto mode, which continuously monitors room temperature and indoor air quality, while also running the fan or heat to the degree of your choosing.
When you first turn on the purifier, it immediately starts assessing the surrounding air quality, and you can monitor any fluctuations in general air quality, particles smaller than 2.5 microns (PM2.5), particles smaller than 10 microns (PM10), volatile organic compounds usually from air sprays or aerosol (VOCs), nitrogen dioxide (NO2), as well as temperature and humidity. I was particularly fond of this feature and frequently looked at these charts to see how the levels would rise or decrease over long periods of time.
