A mechanical filtration system inside your home’s HVAC unit removes dirt, dust and other airborne pollutants that can clog your system and build-up on the coils and other components. This build-up then makes the system work harder and raises your utility bills. It also increases the likelihood of a breakdown.

The filtration system on your HVAC uses a filter to remove these particles before they can spread throughout the system, thus preventing this build-up. Filters become clogged over time and must be changed on a regular basis. These discount filters are easy to install and have the same high quality as pricier filters, but at a lower cost.

High-capacity pleated filters capture more particulates and last longer than traditional panel fiberglass filters. They will last up to three months, though the amount of dust and other irritants present in your home will affect this. These MERV 8 and MERV 11 rated filters also do a lot to improve indoor air quality by removing pollen and mold spores. The MERV 11 filter also removes some odors. They come in a package of four.

If you prefer a non-disposable alternative, you can select the Blue Hog Hair Washable filters. These MERV 4 filters are indefinitely reusable, provided they are washed and allowed to dry between uses.

Check your filters often and replace them when they become dirty to keep your HVAC system in good working order. Clogged filters reduce the efficiency of the system and make it work much harder.
