The air purifier features a high-efficiency particulate air (HEPA) filter that removes 99.97 percent of airborne particles and dual protection activated coconut carbon filters that absorb gaseous particles like smoke and odors. When set to auto mode, the air purifier uses air quality sensors to adjust the fan speeds depending on the needs of your room. Not only does the machine have smart sensors, but it also connects to WiFi, the brand’s mobile app, and smart devices, so you can monitor it via voice control, too. More than 850 shoppers have given it a five-star rating because it’s ultra-quiet, easy to use, and most importantly, removes dust, dander, mold, and pollen from the air. One shopper with allergies said, “Finally, I sleep well and wake up refreshed,” and another reviewer wrote that they no longer have to clear their throat from allergies after using the air purifier. “This unit completely removes the smoke scent and irritants,” a shopper who lives in a community impacted by wildfires added. “It makes living with mold and dust allergies easy.”
