14x20x1 These MERV 8 air filters effectively reduce pollen, dust, pet dander, and other fibers from your indoor air. Removing these airborne particles can help alleviate allergies and sinus irritation that can cause watery eyes, itchy throat, coughing, and sneezing. Aside from the health benefits, this HVAC air filter in your home will also extend the life of your heating and cooling system by making it work more efficiently. These MERV 8 filters contain 14 pleats per linear foot which creates a greater surface area to catch airborne particles. The MERV 8 filter media is electrostatically charged and constructed with spun micro-fiber that also will not retain moisture, which can lead to microbial growth. These HVAC filters should be changed every 1 to 3 months for optimum performance. (Actual Size: 13.75"x19.75")
