True Blue 20x25x1 Air Filter, MERV 11, 4-Pack

The True Blue Allergen Air Filters have a MERV 11 rating, making them highly effective at trapping dust, dander, pollen, and other allergen particles. These filters are made of electrostatically charged material, providing healthier breathing and resisting bacteria and mold growth. Specifically designed for families with allergies and pets, the True Blue Allergen air filter is 53 times more effective than fiberglass filters and can last up to 4 months.

During the manufacturing process, the filter media is charged with an electric current, allowing it to attract very small particles much like magnets attract metal. This results in a far more effective filter that can trap sub-micron airborne allergens like dust, dirt, pollen, pet dander, dust mite debris, microscopic allergens, smoke, and smog. The 100% synthetic filter media will not support the growth of bacteria, mold, or fungi in normal use.

The True Blue MERV 11 Pleated HVAC Furnace Air Filter is designed for residential use to improve indoor air quality by reducing airborne contaminants and microscopic particles. Compatible with almost any brand, this filter is suitable for use in air conditioners, furnaces, heat pumps, and HVAC units.

With a MERV 11 rating, the True Blue Allergen Air Filter can trap up to 79% of particles sized 3.0-10.0 microns, effectively reducing airborne allergens such as dust, dirt, pollen, pet dander, dust mite debris, microscopic allergens, smoke, and smog.

Designed for families with pets and allergies, the electrostatically charged media provides better protection for indoor air, improving and prolonging filter performance by using static electricity to attract and trap smaller airborne particles. This technology outperforms 1-inch standard fiberglass home air filter models.

For optimal filtration performance, it is recommended to replace the home air filter at least every 4 months. Regularly replacing air filters can potentially prevent costly repairs and reduce monthly energy use, as a dirty air filter restricts air flow and forces the heating and cooling or HVAC system to work harder to maintain the desired temperature.

Proudly made in the USA, each air filter is manufactured and assembled locally. Replacing or installing the filter is quick and easy, with instructions provided on the packaging. To ensure a proper fit, measure your current air filter for the exact size and compare it to the True Blue Allergen Air Filter.
