25x29x4 Air Filters for Furnace & AC

Your HVAC’s air filter work to pull harmful pollutants or allergens out of the air as it passes through the system. When the filter turns black, full of dirt, they no longer work. All impurities stay in your indoor air that you breathe. Some expert says that indoor air is more polluted than outdoor, especially when you have kids, pets or allergy sensitive occupants in your family. When you change the air on a regular basis, you protect your family’s health.

The other benefit is you save your system from expensive repairs and your electric bill will stay slightly lower. Before you buy air filters, look for the MERV ratings and choose the one that suits your residential and commercial requirements.
