If you have an air conditioner, heat pump or furnace, your choice of air filter matters. Filters can have a significant impact on the indoor air quality in your Fayetteville, NC home, as well as system efficiency. Here are the three main types of air filters:
Fiberglass Filters
This type of filter consists of layered fiberglass fibers laid over each other. Typically, the fibers are then reinforced with metal grating, preventing failure and collapse. Fiberglass filters are typically the least expensive and least efficient type of filter. They are usually disposable, meaning you will have to replace the filter about once a month while the system is in use.
Pleated Air Filters
A pleated or polyester filter is usually a significant step up from a fiberglass filter. These filters have similar construction but generally provide superior dust-stopping ability.
HEPA Filters
HEPA (High-efficiency particulate air) filters are the “gold standard” in the world of air filtration. The term HEPA is strictly defined by the American Society of Mechanical Engineers. A true HEPA filter must remove at least 99.97% of airborne particles measuring at least 0.3 microns in diameter. Note that the HEPA standard does not apply to particles smaller than 0.3 microns; many HEPA filters can remove smaller particles as well, but that has no bearing on their HEPA status.
It’s important to recognize that while HEPA is a well-defined industry term, other terms such as “HEPA type” and “HEPA-like” are not. Air filters marketed with these terms may be significantly less effective than true HEPA filters.
When it comes to improving indoor air quality in your home, you can’t neglect your air filter. Choosing the right filter can have significant implications for your family’s health and comfort, so the best option is to talk to a professional.
