MERV 11 Pleated HVAC Air Filters with MPR 1000 Electrostatic Media, 4-Pack – Filtrete 16x25x4 or 20x25x4
MERV 11 Pleated HVAC Air Filters with MPR 1000 Electrostatic Media, 4-Pack – Filtrete 16x25x4 or 20x25x4
These MERV 11 pleated HVAC air filters use MPR 1000 electrostatic polypropylene media to capture unwanted particles from air passing through a residential furnace or air conditioner. Filtrete construction targets household dust, lint, pollen, mold spores, pet dander, smoke, and smog while allowing filtered air to continue through the heating and cooling system.
Each option contains four filters, giving households several scheduled replacements in one package. Choose the 16x25x4 or 20x25x4 nominal size to match the installed media air cleaner, and verify the system opening before ordering because nominal and actual dimensions can differ. The source recommends replacing a 4-inch filter at least every 12 months for optimal performance, making this multipack practical for planned annual maintenance.
