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.

*Based on initial efficiency analysis of new filters tested at 3-10 micron particles at 295 feet per minute of airflow.
