Air filters have but one common goal which is to maximize functionality of either the heating or air conditioning system, regardless of brands and types, while achieving distinctive indoor air quality.

These filters all help to make the heating or air conditioning system work efficiently, made possible by removing or avoiding accumulation of dust, dirt, and other tiny air particles. Air particles are captured in these air filters therefore clogging is reduced, if not avoided. Consequently, clogging may result for possible damage on the equipment, which can result to work inefficiently, time-consuming, or labor- and cost-intensive repairs.

Replacing or cleaning of filters is significantly emphasized. It is not surprising since having failed to do any of these tasks can result to losing of the equipment?s functional efficacy. HVAC filter media are available in various types depending on the medium used for production. These HVAC filter media include fiberglass filter media, polyester filter media, dog hair filter media, blue/green filter media, charcoal filter media, and others more. Although many are less expensive, most of these are not much efficient.

For instance, most of the designed induct filters specifically for home forced heating and air conditioning systems are completed from sloppily -spun fiberglass. Such filters happen to be come in a range of sizes and densities, are disposable, and less expensive. Unfortunately, filters that are less-dense may allow higher airflow but do not efficiently remove as much dust. In contrast, filters with higher density are able to take out further air particles may be more restraining with airflow. Higher dense filters also can be that instantly loaded with dust and other particles.
