20x20x1 Air Filters for Furnace & AC

When you don’t change your HVAC’s air filter on a regular basis, dirty air filters make your system’s job more difficult and works harder, which leads to an increase in the energy bill. This isn’t just hitting your pocketbook, but your health as well. The air filter clogged with airborne pollutants and allergens keeps harmful contaminants in the air that you breathe.

Consider replacing your air filter and protect yourself from potential adverse health effects. Merv Filters LLC stocks a variety of air filters with a range of MERV ratings.
