Do Air Conditioners Filter the Air?

Air conditioners cannot purify air, but they do filter dust, pollen, and other allergens. The air filter is part of the entire HVAC system, and all air conditioners have a dust filter in the indoor unit. This traps dust in the air as it circulates, mainly to prevent it from obstructing the inner workings. Most central air conditioning units have two or more filters that clean the air and ensure good air quality as the unit circulates between indoor and outdoor air.

HVAC air filters do exactly what their name suggests. People from the north might call it an oven filter, and from the south an air conditioner filter. No matter what you call it, it's simply an air filter. Factors such as the type of filter you have, the size of the house, the quality of the air, the number of pets in the house, how often you use your unit, and if you or someone in your family has allergies or certain medical conditions can affect how well your filter works.

The air conditioning filter in the home or office is used to remove solid contaminants such as smoke, pollen, dust, grease and pollen to ensure better air quality for occupants. Electrostatic air filters are commonly placed in the return air of the air conditioning unit, where the air is subjected to a high voltage of up to 12 kV between two plates. Preventing these problems and ensuring that you enjoy the best indoor air quality is as simple as changing the filter. However, there are some types of air conditioning filters that could be useful to help keep indoor air clean.

Your oven and air conditioning system use the exact same filter, so there's no need to worry about buying separate filters for each piece of equipment. If you need to install a new filter in your HVAC system or need assistance with maintenance, call Cape Fear Air Conditioning, Heating, & Electrical Company, Inc. If you've noticed a sudden increase in your home's energy bills without a corresponding increase in usage, it could be the air cleaner. While they can provide filtration as claimed, it is highly unlikely that they have been extensively tested with all brands of air conditioners, and the use of non-genuine parts can reduce the performance of the air conditioner, cause damage, and void the warranty.
