This Aprilaire Spaceguard 20x25x6 replacement furnace filter is a MERV 11 (AFB Gold) aftermarket replacement manufactured by FilterBuy. It is designed to fit Aprilaire 2200 and 2250 air cleaners.

Note that unlike the replacement media, this filter is a boxed cardboard frame that is designed to drop directly into the existing plastic housing, not requiring additional fingers for support.

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 2 filters.

Note that AFB 20x25x6 Apriliare-Spacegard replacement filters come in AFB Silver (Merv 8), AFB Gold (Merv 11), and AFB Platinum (Merv 13). The AFB gold is a premium quality replacement filter that provides superior filtration for dust and other allergens. We recommend the gold for pet owners or people with allergies.
