What are HVAC Filters?
Appliances like Air conditioners and heaters take in air from the surrounding and give out cold or hot air respectively. The outside air contains many minute particles called pollutants. If these pollutants are allowed to enter the internal part of these appliances, they may have adverse effects on their working. To prevent these pollutants from entering inside, there are filters attached. These filters used within Air conditioners or Heaters are called HVAC filters.
An HVAC filter is a filter that is used in a heating, ventilation and air conditioning system. The filter increases the efficiency and longevity of the HVAC system by protecting it from dust and airborne particles. It is therefore an integral, yet often overlooked part of the system. In addition to protecting the HVAC system from damage, some HVAC filters are designed to improve the quality of the interior air. Whether providing air conditioning or heating, an HVAC system works by drawing air into it, heating or cooling the air and then forcing the air out into the areas requiring heating or cooling through a series of ducts. The interior air of a building is a mixture of human skin particles, microscopic insect droppings, pet dander, pollen, fabric particles, and any other of a wide variety of pollutants. As air circulates through the HVAC system, these interior pollutants are drawn through the system and can cause damage to an HVAC if the system were left unprotected. HVAC filters wo
