The HEPA Filter in your Coway AP-1512HH Mighty air purifier captures microscopic particles like dust, pollen, pet dander, and mold spores to keep your air clean and healthy. Over time, the filter accumulates these particles and becomes less effective, reducing air purifier performance. Replacing it regularly ensures continued optimal air quality.
