15x20x1 MERV 11 Allergen Air Filter (4-Pack) | Electrostatic Pleated HVAC Furnace Air Filter | Replacement Filter for Home Use | Made in USA

TRAP AIRBORNE CONTAMINANTS: The Allergen Air Filter is rated as a MERV 11, meaning it can trap up to 79% of the particles sized 3.0-10.0 microns. This filter effectively reduces airborne allergens, including dust, dirt, pollen, pet dander, microscopic allergens, smoke and smog.

DESIGNED FOR FAMILIES WITH PETS AND ALLERGIES: Better protect your indoor air with electrostatic charged media to improve and prolong filter performance by using static electricity to attract and trap smaller airborne particles. This technology outperforms 1-inch standard fiberglass home air filter models.

REPLACE EVERY 4 MONTHS: To maintain optimal filtration performance, change your home air filter at least every 4 months. Regularly replacing air filters can potentially prevent costly repairs and help reduce monthly energy use. A dirty air filter restricts air flow and forces your heating and cooling or HVAC system to work harder to keep your home at the desired temperature.
