Coway Air Purifier Airmega 200M True HEPA with 361 sq. ft. Coverage in White

4-Stage filtration system (Pre-filter, deodorization filter, true HEPA filter, vital ion) captures and reduces up to 99.97% of 0.3-micron particles in the air, including pollen, pollutants, and other allergens. It also reduces volatile organic compounds and reduces odor. Coway airmega's real-time air quality monitor keeps you informed of the quality of your air. In auto Mode, the fan and purification levels adjust to the space as needed. Fan speeds are available in 1, 2, and 3 stages by manually setting up. While auto mode automatically optimizes the speed setting 1 through 3 based on the level of indoor air quality. Filter replacement indicator checks both pre-filter and HEPA filters respectively to let users be aware of when to wash or replace the filter.
