What You Need to Know About the Air Filter in Your Home’s HVAC System
Today’s HVAC equipment typically come with their own air filter, which HVAC professionals recommend replacing every two months or so to help ensure the indoor air quality delivered by system. Since this material’s job is to prevent dust and other airborne allergens from getting into the home through heating and air conditioning units, it tends to accumulate a lot of dirt over time. If not replaced or even cleaned, it’s likely to be the cause of the system’s failure.
What normally happens is that a dirty air filter prompts the unit’s fan motor to work extra harder and consume more energy; with the system constantly overworked, the proper functional life span of the unit will be reduced significantly. Aside from this, over time, the unit will simply not be able to achieve the most ideal interior temperature no matter how hard it works. These only prove how crucial it is to heed the advice of HVAC specialists regarding the cleaning or replacement of the filter in order to maintain the good working condition of the AC.
Air filters come in different types, and it’s to everybody’s advantage to know what type they’re currently using so they can effectively be guided on how well the filter works to prevent tiny particles from passing through the system, when it should be replaced, and even what to replace it with for better performance.
This is the most common type of home air filter; it’s made up of layered fiberglass fibers which are laid over each other to form the filter media. It is reinforced with a metal grating that supports the fiberglass so it would not collapse. This is what HVAC experts require to be changed every two months or so.
Polyester and pleated filters
They are quite similar to the first type; however, they have a much higher resistance to airflow and they offer superior dust-stopping ability. If you don’t want compromised airflow, these filters are perhaps not the best option.
High efficiency particulate arrestance (HEPA) filters
These have the ability to filter the air passing through them at a very fine scale. The best HEPA filters, which are used by the US Department of Energy contractor, can effectively filter 99.97 percent of all particles 0.3 microns or larger. This then means that the buildup of dirt on these filters can be more than the two previous types.
Washable air filters
As the name implies, these filters are washable so they can be used for a much longer time. To improve the cooling or heating performance of the HVAC unit, it just needs a thorough wash.
Air filters certainly can contribute to the interior environment of homes; with the information provided here, you can make sure these materials do their job well in maintaining the right air condition within your home, as well as in extending the functional lifespan of your HVAC unit so you won’t have to replace your unit much earlier than you want to.
