What is HVAC filter? As the name suggests a HVAC filter is a filter that is used in a heating, ventilation and air conditioning system. The HVAC filter is used to increase 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.
What is HVAC filter? The most economical HVAC filters are made of spun fiberglass. Spun fiberglass filters are able to filter only larger sized particulates and should be changed at least once a month. Disposable pleated HVAC filters are more expensive than spun fiberglass filters but are also more effective at removing air particles because of the greater surface area created by the pleats. Pleated filters do not need to be replaced as often as spun fiberglass filters do. Electrostatic Filters are more effective at capturing small and large particulates than either disposable spun fiberglass or pleated filters. As air passes through, a static charge is created that attracts and holds both smaller and larger sized particulates. Electrostatic filters are typically reusable and need to be washed regularly to stay effective. They are also more expensive than disposable filters.
To know what HVAC filter is, you'd better know the working principle of it. 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. You know that the interior air of a building is always 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 Air filter system were left unprotected.
HVAC filters work by providing a physical barrier between the air intake and the moving parts of the HVAC system. As air is drawn in, particulates are caught by the filter and prevented from entering while the air is allowed to pass through. Some HVAC systems have a filter at the air intake and also at the air exhaust, further preventing any pollutants from being blown back into the interior environment. HVAC filters have been widely used in our daily life. If you are in need of HVAC filter, you can visit www.hefilter.com for further information.
