Fiberglass Filters

The most standard type available is fiberglass filters. It’s composed of fiberglass strands that can trap dust and big airborne particles.

You could use fiberglass filters in both air conditioners and furnace units. These filters are cheap, disposable, and effective but lack air-purifying qualities.

HEPA Filters

HEPA filters, or high-efficiency particulate air, are part of freestanding air purifiers that offers high-end filtration. Some houses installed HEPA filters as part of the central air system to clean the air around the furnace. HEPA filters have ultraviolet lights that neutralize and denature cellular organisms. 

Moreover, some maintain their effectiveness by using activated carbon filters. Though they are ideal for stopping indoor impurities and improving air quality, they can lower your system’s airflow. 

Polyester Filters

Polyester filters are median size and have the highest grade materials. They kill and trap eighty to ninety-five percent of particles five microns or bigger. A polyester filter can be more pricey than a fiberglass filter, but it gives more protection against impurities. 

Pleated Filters

Pleated filters are more step-up fiberglass filters that stop and trap dust particles and allergens. You can pick between a disposable or washable type for your HVAC system. Furthermore, a pleated filter is a bit more secure than a fiberglass one.

So if you pick a pleated filter, your HVAC system will have to operate harder to draw air using the unit. As a result, the air quality in your home can improve, but your HVAC system might lose efficiency. 

Media Filters

Media filters have a paper-like textile creased into folds in a metal cabinet. While the filter is about five to six inches wide, it can cover seventy-five square feet if unfolded. It means media filters are seven times more efficient than common air filter types.
