• Highly efficient filtration system: 3-stage air filtration system (pre-filter, activated carbon filter, and true HEPA filter) effectively removes 99.97% of airborne particles smaller than 0.3 microns
  
• Compatible air purifier: The 3-in-1 HEPA replacement filter is designed for use with your TaoTronics TT-AP001 air purifier (sold separately) to extend the life of your air purifier
• Before use: The filter is sealed to preserve its shelf life. Remove the filter from the plastic bag before placing it in the TaoTronics air purifier
• Note: For optimal cleaning efficiency, we recommend replacing the filter at least once every 3 to 6 months, depending on the intensity of use and the air quality in the room.
