Pleated air filters are made with material that has been pleated or folded to provide more surface area.
These pleated air filters are often the most efficient of all the media air filter types and are a whole house air filter.
By increasing the surface area for collecting dust, airflow through the pleated air filter is less restricted. It is important to monitor pleated air filters and change them when required so they do not become plugged with too much dust and restrict airflow through your heating or cooling equipment.
The Real Cost Of Inefficient Media Air Filters
There are many different types of media air filters but most are not worth using in your equipment because they are very inefficient. A good way to decide if a media air filter is worth using is to hold it up and look through it. If you can easily see through it don't waste your money.
The purchase price may be lower but the real cost is in the poorer air quality and higher equipment maintenance costs.
The dust that passes through this type of media air filter will end up on your furniture and in the duct system. If this media air filter is in an air conditioner or heat pump system, dust will eventually build up on the surface, and between the fins of the heat exchanger coil and restrict airflow.
Under some conditions this could actually lead to equipment failure.
