HVAC pleated air filters are one of the three best performing panel type furnace filters available for you to choose from. These filters are made with a material that is folded into pleats. This pleated filter material is used to produce 1 inch, 2 inch, 4 inch and even 6 inch deep, pleated panel filters. The most common sizes used are 1 inch and 2 inch.
Folding the filter material into pleats increases the surface area of the filter and extends the useful life of the filter. If the material were used as a flat surface without being pleated it would clog with dust in a matter of days. This would lead to a decline in system performance.
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.
Most pleated air filters are 20 – 30 percent efficient. This of course depends on the material used in the construction of the filter. Pleated air filters can be up to 60 percent efficient and some manufacturers claim over 85 percent efficient if the filter surface is treated with an oil like substance that is very sticky.
Some pleated air filters have a wire mesh on the backside of the filter. This is to help the filter maintain its shape and not collapse under the pressure from air passing thru it. The more efficient types do not always have this wire mesh because the filter material is rigid enough to hold their shape.
Unless you suffer from allergies, a pleated air filter will do an adequate job of filtering the air that passes through your heating and cooling equipment.
There are many different types of panel air filters available but many are not worth using in your air conditioner or furnace because they are very inefficient. A good way to decide if a panel 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 poor air quality and higher equipment maintenance costs.
The dust that passes through this type of 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 certain conditions this can actually lead to equipment breakdown.
Although pleated air filters will do an adequate job of reducing dust in your home they do not work as efficiently as media air filters or electrostatic filters.
