Breathe easier with these Filterbuy MERV 11 air filters! This 3-pack is perfect if you have pets, allergies, or just want cleaner air in your home. The MERV 11 rating means they trap up to 95% of airborne particles like pollen, mold spores, pet dander, dust, and even smoke – comparable to filters labeled MPR 1000-1200 or FPR 7. They're designed with an electrostatic charge and 14 pleats per foot to capture more junk without restricting airflow in your HVAC, furnace, or AC system. The frame is made from industrial-grade beverage board (which is recyclable) with a dual wire backing, making it way sturdier than flimsy cardboard; it can handle temps up to 200°F and moisture. Actual size is 17.5\ x 24.5\ x 0.75\ (so they fit a nominal 18x25x1 slot). Arrows on the frame show you which way the air flows for easy installation. Plus, they're made in the USA and last about three times longer than cheap fiberglass filters. A quick note: packaging or labels might look different sometimes, but the filter inside performs exactly the same. Keep your system running efficiently and your air fresh with these reliable filters.
