What Type of Filter to Use.

Posted on: February 9, 2012

Air filtration on air conditioners was started in order to keep the coil clean. Many old central heating-only systems had no filters installed because it was thought to serve no purpose. Now the primary reason people are interested in filtration is for air quality. There are a variety of filters that can be used on central heating and air conditioning systems. The spun fiberglass, which is probably the least expensive, also probably does the least for keeping the air and your equipment clean. It will probably cost you more money in the long run using those filters. What dirt the filter doesn’t catch is usually caught in the evaporator coil. Cooling your house with a dirty coil costs more that cooling with a clean coil. The cost of an extensive coil cleaning can be avoided by using a good filter. A polyester filter costs a little more but will save you in the long run. Other types of efficiency filters or letting you filters get too dirty can cause additional problems.
