Moving top, The easy-to-use control panels are well lit where you can cycle between the four fan speeds and enable Auto mode. Auto mode will use a higher fan speed when a large concentration of airborne pollutants is detected. Otherwise, it will remain at low speed.

Filters And Performance

Winix A231 4-Stage HEPA Air Purifier with PlasmaWave Technology says it all. Drawing air pollutants at a 360° angle, the outer fine mesh pre-filter traps large particles like dust, hair, fiber, and lint from passing through. The activated carbon filter absorbs smoke, and odors coming from cooking, pets, food, chemical fumes e.g. cigarettes, VOCs, radon, asbestos, formaldehyde. It will also prolong the HEPA filter life from being damaged by smoke particles. The True HEPA filter capture 99.97% of airborne allergens including mold, pollen, and pet dander as small as 0.3 microns. PlasmaWave Technology electrically discharges dual polarity ions Hydroxyls to neutralize bacteria and viruses including influenza strain H3N2.
