High Efficiency Filter for Ventilation and Air Conditioning

Views: 0     Author: Site Editor     Publish Time: 2022-09-14      Origin: Site

An HVAC filter is a filter used in heating, ventilation and air conditioning systems. Filters improve efficiency and longevity by protecting HVAC systems from dust and air particulates. Therefore, it is an integral part of the system, but often overlooked. In addition to protecting HVAC systems from damage, some HVAC filters are designed to improve indoor air quality.

Whether providing air conditioning or heating, HVAC systems work by drawing air in, heating or cooling it, and then draining it through a series of pipes to the area where it needs to be heated or cooled. The air inside buildings is a mixture of human skin particles, insect droppings, pet dander, pollen, fabric particles and a variety of other pollutants. As air circulates through the HVAC system, these internal pollutants are drawn into the HVAC system and can cause damage to the HVAC system if it is not protected.


BS1063(1)

The HVAC filter works by providing a physical barrier between the air intake and the moving parts of the HVAC system. When the air is sucked in, the particles are trapped by the filter, and when the air is allowed through, the particles are prevented from entering. Some HVAC systems have filters at both the intake and outlet ports to further prevent any contaminants from being blown back into the indoor environment.

The most economical HVAC filters are made from spun glass fibers. Spinning fiberglass filters can only filter larger particles and should be replaced at least once a month. Disposable folding HVAC filters are more expensive than spun fiberglass filters, but are also more effective at removing air particles because folding filters have a greater surface area. Folding filters do not need to be replaced as often as rotating fiberglass filters.

BS049 (5)

Hepa filters capture at least 99.7 percent of air particles and remove almost all allergens that can enter HVAC systems. People with asthma and severe allergy problems often use HEPA filters because these actually improve indoor air quality. Hepa filters are among the most effective and expensive filters on the market and are often reusable.
