A true HEPA air purifier best for small rooms! This purifier is AHAM certified for rooms up to 230 square feet. Winix uses a 4-stage filtration system with this purifier. First, a fine mesh pre-filter catches large contaminates and prevents them from clogging the downstream filtration. Then, a true HEPA filter captures 99.97% of airborne allergens down to 0.3 microns in size; this takes care of most dust, smoke, pollen, or pet dander. Then, your air is filtered through an activated carbon filter to reduce odors and capture VOCs. Finally, the air passes through the Winix Plasma Wave filter which creates hydroxyls to generate positive and negative ions to separate hazardous contaminates at a molecular level (without generating ozone!). This filtration method meets the California Air Resource Board's AB2276 standard for ozone emissions with less than 0.05 parts per million. A smart sensor with an auto mode, a sleep mode, an air quality indicator, and a 2-year warranty top off this high-end yet budget-friendly small room purifier.

Small to medium sized spaces that need better air filtration than what a basic air purifier can handle and for people who want elegant simplicity.
