How to clean your AC air filters may vary according to the type of unit and air filters your AC has. So, check your unit's manufacturer manual just to be sure. Another factor to consider is the material you'll use. Avoid using abrasive materials to clean your AC parts. They may cause tears or damage and that's the last thing you'd want to happen with your AC. 

And above all, remember safety first! Always turn off your AC and remove the plug from the power outlet before cleaning. This seems like an obvious first step, however, there may be instances that we can overlook this especially if there's too much going on around us. So, when it comes to appliances, the golden rule is to always unplug first!

Split High Wall

Inverter Hi Wall split systems are powerful, compact air conditioning units that use technology to both heat and cool rooms. These systems are usually mounted high on the wall. They also use inverter technology: the latest and most efficient air conditioning technology on the market. 

Moreover, having a split type unit means that the AC system consists of two units⁠—one inside and one outside. These systems cool your space by expelling hot air using the outside unit and replacing it with circulated cool air using the inside unit. Before cleaning, refer to your unit's manual if possible.

What are the types of AC filters?

The types of AC filters available on the market include:

Fiberglass AC filter

These filters are less costly with a basic filtration level. While they only cost a few bucks, they are not recyclable so you have to change them often. Since fiberglass filters are disposable, it's best to check or change them every month.

They may be more expensive than fiberglass ones, but pleated filters can be reused and don't require too much replacement. If you want to get what you pay for, then you can go with pleated filters.

What materials should I use for AC filter cleaning? 

To ensure that your AC filter will be clean, here are some materials you can use for cleaning: 


For DIY regular maintenance, you may vacuum your AC filter and fin. There are handheld vacuums available and are perfect for cleaning appliances. Use an attachment without a brush, as this could damage the filter. If you own pets, go over the filter a few extra times to get out as much hair as possible. Remember not to push too hard on the filter as you vacuum because you may end up tearing or denting it.

Basin, Water, and Liquid Detergent

Fill up your tub or basin with room-temperature water. Then, add a little bit of regular liquid detergent and mix it well, so the water lathers up. Place the filter in the container. Make sure it’s submerged. Don’t use brushes or other sharp tools on the filter, as they may cause tears and damage.

Vinegar Solution

Mix up a one-to-one solution of vinegar and water, and add it to a spray bottle. Spray both sides of the filter, and give it 10 minutes for the solution to kill bacteria. Rinse the filter afterward. 

Dry Microfiber Cloth or Newspapers

AC filters need to air dry, and it can take several hours to become completely free of moisture. To help the process, you can put microfiber cloth, or newspapers on the ground underneath the filter. Lean the filter up against the wall on top of the cloth or newspapers. Once dry, you can re-install the filter in your air conditioning unit.
