16x25x5 MERV 13 Replacement Furnace Filter

Keep your compatible heating and cooling system supplied with a properly sized replacement filter using the Nispira 16x25x5 MERV 13 furnace filter.

The pleated filter media helps capture dust, pollen, pet dander, and other common airborne particles as air passes through the filter. A laminated diamond-pattern support grid helps stabilize the pleats and maintain the filter’s structure during normal HVAC system operation.

For convenient shipping and storage, the filter arrives in a compact folded form. Before installation, fully unfold the filter media, position the two side panels, and secure them using the included plastic rivets.
