Coway Airmega 400 True HEPA Air Purifier with Smart Technology ($649)
When you're allergic to pet dander, dust, and pollen, a simple air purifier from the drugstore won't do. This Coway Airmega 400 Air Purifier is so powerful that it can capture 99.999 percent of nano-sized particles down to 0.01 microns — including the aformentioned allergens, as well as most bacteria and mold. It also has smart technology features with three modes — Auto Mode, Eco Mode, and Sleep Mode — that you can adjust based on your immediate needs. Get full details in my complete review of the Coway Airmega 400 True HEPA Air Purifier with Smart Technology.
Editor Quote: "I can say it's actually made a difference for me during allergy season and beyond. It's also pretty effective for any kind of air pollution, whether released from wildfires, factories, cars, or construction. I noticed right away that my breathing isn't as labored and I feel less congested. It's also pretty convenient to operate: I can change the settings manually based on air quality or leave it in Auto mode to do the work for me. Overall, in terms of function and ease, this air purifier actually impressed me. Most importantly, it helped alleviate my symptoms during allergy season in a way I didn't think was possible." — Jessica C. Andrews, senior style director
