Smart Air Purification

Purify your home air quality with the Keen Home Smart Filter. This seamless, snap-in filter fits between the Keen Home Smart Vent and its removable faceplate for instant air purification. The smart vent filter's simple design and easy installation make it an attractive cost-effective alternative to standard air filtration units.

  • Neutralizes odors, germs, and harmful pollutants before entering a room
  • Antimicrobial coating prevents growth and spreading of mold and mildew on the filter
  • Guarantees air filtration without reducing heating/cooling performance

3M High Air Flow Technology allows the smart vent filter to continually clean ventilated air without blocking and reducing heating/cooling in a room, saving you time, energy, and money whenever you use your HVAC system. Placing multiple Keen Home Smart Filters in a home increases whole home air quality while still saving costs compared to stand-alone air purifiers.

Installation Details

Remove the faceplate from the Smart Vent and simply place the Smart Filter over the Smart Vent. The filter uses a magnetic frame to quickly adhere to the Vent.
