How to Clean Your AC Filter

Clean Your AC Filter

If your air conditioner is buzzing, using large amounts of energy, and/or working to very little effect, it might be time to clean or even replace its filter. This brief guide will help explain the ins and outs of this simple process.

Who Doesn’t Like Clean Air

The air conditioner’s filter is what keeps the air quality above an acceptable minimum by catching all of the particulates that would otherwise be pumped into the home and breathed in by the occupants. With a dirty filter, less space is available for good air, decreasing the airflow.

The Actual How To

First and foremost, turn off the AC. You do not want it to be running while you work on the parts nor while the filter is removed. If you try to work on an air conditioning unit while the power is still on, the fans could cut you, you could be electrocuted, or you could simply break the machine.

Next, you’re going to take a vacuum and begin detailed work vacuuming the particulates and fuz-like buildup off of the filter. If vacuuming doesn’t render the filter sufficiently clean, you’ll have to wash it.

To wash the filter, fill a sink with equal parts vinegar and water. Rinse thoroughly and softly scrub the buildup off until the filter has been cleaned. If you notice that the filter is worn and torn in places, it might be time to replace it.


A clean air filter leads to clean air, which in turn leads to a happier, healthier life. By vacuuming and washing the filters in your air conditioning unit, you’ll be able to experience noticeably better performances from your AC unit.
