DonÕt be fooled by other vendors that offer ÔreplacementsÕ but are just cheaper box filters with a gasketing applied in order for a tight seal. Our frames are manufactured specially to fit for an air-tight seal.
This AFB Gold MERV 11 replacement filter is designed to last 6 months. The filters ship directly from the manufacturer to your doorstep, allowing AFB the ability to offer a premium product at a reasonable price.
Each quantity purchased is for a Pack of 4 MERV 11 filters.
Note that Trane 21x23.5x5 replacement filters come in AFB Silver (Merv 8), AFB Gold (Merv 11), and AFB Platinum (Merv 13). We recommend the MERV 11 filters for home or business use for people with pets or allergies. If you have asthma or other respiratory illness, we recommend the Merv 13.
