Air Conditioning System Filters: An Intro to Maintenance and Selection

On a hot and humid day, central AC helps you to feel more comfortable by cooling the air and reducing humidity. It also benefits your body in other ways. An important component of the system is the air filter.

Breathing Is Better

Central AC improves indoor air quality by trapping pollutants and helping to prevent the buildup of mold and mildew. Impure air has been linked to asthma in some people, and it is your system’s air filter that traps the pollutants in the air. It acts as a mesh screen that stops particles larger than a certain size in the air intake path.

Ratings for Air Filters

Many kinds of air filters are on available. The standard type captures dust. Those with the higher MERVs (Minimum Efficiency Reporting Value) remove a greater amount of pollen, dust mites and other unwanted airborne matter. They are often categorized by mesh size. Air filters for residential use have a MERV that ranges from 1 to 13. The higher numbers mean that the filter can remove smaller contaminants from the air.

If you don’t know the MERV rating your manufacturer suggests for your system, speak to an AC technician. The age of your system, energy costs and other factors may affect the choice of the air filter that’s right for your cooling system. The incorrect air filter could end up causing you to call for AC repair in Naperville.

Air conditioning is no good if the air filter is not kept clean by changing it regularly. If you don’t know what your manufacturer’s interval recommendation is, ask an HVAC technician.
