What is AC filter material?

AC filters are mostly made out of a fine fiberglass thread, which is then spun on a frame or from fine paper or cloth wrapped on a cardboard frame. Some particles which an air conditioner filter can help protect you against include: Pollen. Mold.

Why are AC filters pleated?

A pleated air filter uses screens of polyester, plastic fibers, or cotton to remove dust and other particles from the air that enters the HVAC system. Unlike standard filters, they have pleats, or folds, that offer more surface area for filtering more debris that could otherwise destroy the AC coils or blower fan.

Are pleated AC filters better?

While fiberglass air filters will do the job in the most basic way, in most cases, pleated air filters are much better. They can filter out smaller particles – important for people with airborne sensitivities. They are less likely to clog in a short amount of time, and they can last up to 90 days.

What happens if you put an HVAC filter in upside down?

If you set your filter up backwards, the normally collective end of the device will not face the air supply. In effect, your filter will help keep debris in the air. This results in a clogged filter and improperly cleaned air when it reaches your lungs.

Can AC filter be washed?

Wash the Filter Rinse it off with fresh water and let it fully dry before returning it to your AC unit. If the filter is too large to fit in your sink, you can also wash it with a garden hose outside. Do not use a pressurized setting on your hose because you might accidentally damage the filter.

Do pleated filters restrict airflow?

Because they restrict airflow to your HVAC system. Pleated, high-MERV filters definitely capture a lot of pollutants, but they also restrict the movement of air into your blower or furnace. As a result, the fan has to work harder to heat and cool your home, reducing efficiency.

Do pleated filters last longer?

Pleated air filters have more surface area allowing them to capture more airborne pollutants and allergens such as pollen, pet dander, and mold spores. Pleated filters are stronger and can last up to 90 days, three times longer than fiberglass filters. Fiberglass air filters are not as strong as pleated filters.

How do you know if your air filter is backwards?

So be sure to look for the arrows that are printed on the sides of the filters because they show you which way the filters are supposed to be installed. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling.
