Get to Know the 7 Types of AC Filters

Air filters are the key part of an air conditioning system. AC filters protect the air you breathe from contaminants as well as safeguard AC systems. They can catch human hair, fine sand, and even fine particles.

There is nothing wrong with choosing any AC filter; however, some AC filters work better in some applications than others. Before buying a new air filter, pick the right one.


You probably have seen a fiberglass filter before. They are made up of spun glass layered one on top of the other. This type of filter keeps dust and small insects out of the system. It’s most efficient when replaced every 30 days.


A fiberglass air filter is one type of disposable air filter, but this one is a step-up since it is moisture-resistant, can trap small particles, and has a coated frame for extra stability.

You will save plenty of money by using a washable air filter. The investment may be more expensive; however, it will pay for itself quite quickly. This type of filter must be cleaned carefully to prevent bacteria buildup or mold from developing. It should be left totally dry before it’s installed, or it could eventually lead to decay. Taking proper care of a washable air filter can extend its life five years.
