HVAC filter is an important component of an HVAC system. It is used in furnaces, air conditioners, heat pumps, etc. HVAC filters are made of a fiberglass material or from pleated paper enclosed in a frame. This apparently minor component is very critical for the heating and cooling systems of any place. It cleans the air that circulates through the system by trapping dust particles and other contaminants. 

HVAC filters prevent bacterias, particulate matter, etc. from mixing with the indoor air hence giving clean air which is crucial for our good health and comfort. It is considered one of the most important components of the HVAC system and is yet overlooked.
