The work of the air filter in an air conditioning system is to keep the cooling coils and air inside the home clean and free from all forms of air contaminants such as pet dander and ozone emissions. In the market these days, you will come across different types of air filters such as HEPA, standard, pleated, electrostatic and electronic filters. The popular ones out of these and which can be used to remove air pollutants from air conditioners are the standard, pleated and electrostatic filters. You will find these filters situated in walls, ceilings, furnaces, or right in the air conditioner. The standard air filters, which are made of spun fiberglass with cardboard frames, have the ability to remove 10 percent of the airborne contaminants.It must be changed once every month.

About 35% to 40% of airborne contaminants is usually captured by pleated air filters. Because of their greater surface area with filter material folded back and forth like a paper fan, manufacturers assert that these filters can last between two to four months. You will be expected to part with between $5 to $20 in order to get these filters and this is slightly more than that of standard filters.

Electrostatic filters make use of filter media that use an electric charge to attract the airborne particles. These filters cost range from $20 to $100 each. You only need to change these filters once in every year. But people with allergies consider the use of electronic air filter in air conditioner which functions in the same way as the electrostatic air filters. However, it is more superior to electrostatic air filters because the air flow inside the air conditioning system is not obstructed. Whatever type of air conditioner you have, ensure that a contractor is contracted to check the cleanliness of the filter’s coils at least once in a month.

You should make sure that the air conditioner’s filter is changed on regular basis as clogged and dirty filter will hamper the airflow in the system and reduce its efficiency by harming the coils’ heat-absorbing capacity.
