Honeywell® 16" x 25" x 4" High Performance Return Grille Filter Merv 10
About This Product
Provides air filtration equivalent to typical four inch media filters in a one inch return grille space. Up to 10X 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 the HVAC system. Additionally, these filters last up to 3X longer than standard 1 inch filters, which means less maintenance is required for improved air quality.
