When installed into your home’s ceiling or wall return grille(s), Honeywell’s High-Performance Return Grille Filters provide air filtration equivalent to typical four-inch media filters in a one-inch return grille space.

The Return Grille Filter is up to 10 times more effective than standard one-inch filters at trapping and filtering dust, as well as reducing pollen, mold spores, bacteria and other allergens passing through your HVAC system. This ensures that cleaner air is distributed throughout your home. Additionally, Return Grille Filters from Honeywell last up to three times longer than standard one-inch filters, which mean less maintenance for improved indoor air quality.


  • Mounts in most return filter grilles.
  • Pleated for greater media capacity.
  • Low pressure drop provides a comfortable air flow.
  • Maintains equipment efficiency longer than standard filters.
