16x20x1 MERV 11 Allergen Air Filter, 4 Count

CLEANER INDOOR AIR: The True Blue MERV 11 Pleated HVAC Furnace Air Filter is designed for residential use to improve and freshen indoor air quality by reducing airborne contaminants and intruding microscopic particles. This filter is compatible with almost any brand and is appropriate for use in air conditioners, furnaces, heat pumps, and HVAC units.

TRAP AIRBORNE CONTAMINANTS: The True Blue 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, dust mite debris, microscopic allergens, smoke, and smog.

DESIGNED FOR FAMILIES WITH PETS AND ALLERGIES: Enhance indoor air quality with electrostatically charged media. This technology improves and prolongs filter performance by attracting and trapping smaller airborne particles using static electricity. The True Blue MERV 11 filter outperforms 1-inch standard fiberglass home air filter models.

REPLACE EVERY 4 MONTHS: Maintain optimal filtration performance by changing 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, cooling, or HVAC system to work harder to maintain your home's desired temperature.

PROUDLY MADE IN THE USA: Each air filter is manufactured and assembled in the USA. Replacing or installing the filter is quick and easy! Simply follow the instructions on the packaging. To ensure a proper fit, measure your current air filter for the exact size and compare it to ours.
