how to clean AC filter

A clean air conditioner filter is essential for two reasons: it ensures that your AC unit runs efficiently and protects you and your family from harmful airborne particulates. This blog post will show you how to clean AC filter in just a few minutes.


With a bit of regular maintenance, you can prolong the life of your AC unit and breathe easily, knowing that your family is protected from harmful pollutants.


Importance of Cleaning AC Filters

There are two main reasons you should keep your AC filters clean: to improve efficiency and prolong your unit’s life


When air conditioning units run, they draw in air from the surrounding area and circulate it through the AC unit. The filter’s job is to catch any dirt, dust, or other contaminants that may be in the air before it has a chance to enter the unit. Over time, however, the filter will become clogged with these contaminants, reducing the airflow that can pass through it. This decrease in airflow will cause the unit to work harder to cool your home, leading to increased energy usage and higher utility bills. In addition, all that extra work will strain the AC unit, leading to premature failure. 


Fortunately, cleaning your AC filter is a quick and easy process that does not require special tools or skills. We recommend doing it every month or two, or more often if you have pets or live in an area with a lot of dust in the air.


How to Clean The AC Filter?

Turn Off Your AC Unit and Unscrew the Filter Cover

Before you begin, turn off your AC unit at the thermostat. Then, locate the filter cover and unscrew it. Depending on your AC unit model, the cover may be found on the front or side of the unit. After removing the cover, you should see the filter itself. If your filter looks especially dirty, it’s probably time to replace it. However, proceed to step two if it just looks like it could use a good cleaning.


Vacuum Both Sides of the Filter with the Brush Attachment

Using the brush attachment on your vacuum cleaner, gently vacuum both sides of the filter to remove any surface dirt or dust. Be careful not to bend or damage the filter as you vacuum. Otherwise, you’ll need to replace it. 


Soak the Filter in Warm, Soapy Water

After vacuuming both sides of the filter, it’s time to clean it. Fill a sink or bucket with warm water and add mild dishwashing soap. Then, submerge the filter in the soapy water and let it soak for 15-20 minutes.


Rinse Thoroughly

After that time has elapsed, rinse off the filter with clean water until all soap residues have been removed. Let the filter dry completely before putting it back in your AC unit.


Reinstall The AC Filter

Once the filter is dry, put it back in your AC unit and screw on the cover. Then, turn on your AC unit at the thermostat and enjoy the cool, refreshing air.



Cleaning your AC Filter is an essential part of maintaining your air conditioner. It is a quick and easy way to improve the efficiency of your unit and prolong its lifespan. We recommend doing it every month or two, or more often if you have pets or live in an area with a lot of dust in the air. With this easy-to-follow guide, you can clean your AC filter in just a few minutes and keep your home cool and comfortable all summer!
