Cleaning your home’s air filter is one of the easiest and most important steps you can take to protect your heating and cooling system. Without an air filter, dust can stay with the working unit. Dirty units can result in anything from inefficiency to fire, so never be lazy in cleaning them!
Your home’s air filter is usually found behind a vent. A flat wall cold air filter is usually near or on the ceiling. A baseboard cold air filter is typically located at or near floor level. Some air filters are made to be cleaned, while others are disposable and should be replaced. If you are unsure which type you have, a quick internet search for the brand will clue you in; however, it’s safe to assume that filters with cardboard frames are not meant to be reused.
Cleaning Home Air Filters
If you have a reusable air filter, cleaning it is actually quite simple. You will need:
-Ladder or stool
-Brush for cleaning
The Cleaning Process
Start with using a ladder or stool to reach your filter. Open the vent. Usually there is a screw to remove or a simple latch that just requires a flip to the opposite position.
Then, remove the filter. Take the filter outside for cleaning if possible, as this can get dirty! Use the brush to remove dust and debris. Next, turn the vacuum on and use the hose to suction remaining loose material from the filter.
Once the loose dirt is removed, turn the filter over and let water run through the filter in the opposite direction of air flow. It’s best to use a low pressure spray for this type of project. Make sure the air is dry completely before reinstalling.
