How To Clean An Air Conditioner Filter

Cleaning your air conditioner’s filter is necessary for it to operate effectively. A neglected and dirty air conditioner filter covered with grime and dust obstructs the airflow, causing the unit not to cool as it should. However, you might have wondered how to clean an air conditioner filter by yourself and how frequently the cleaning should be.  

It is preferable to clean the air conditioner filter once before summer and at least once every month when you are utilizing it. Using running water alone can’t remove the dirt from your unit’s filter, so you must consider some steps. 

This article can help you achieve your clean air filter at home and get your air conditioner working as if it’s brand new. 

5 Simple Steps to Clean an Air Conditioner Filter

An air conditioner is such as lifesaver, especially during hot weather, as long as it is functioning well. If you have noticed a performance drop on your unit or a strange odor when you turn it on, it requires some cleaning. 

However, before cleaning your aircon conditioner filter, make sure you can wash and reuse it because other AC unit filters should be disposed of and changed. 

Here is a step-by-step guide to ensure that you get your aircon filter well-cleaned:

Step 1: Remove the filter

First, turn off your air conditioner and remove its cover. There are screwed aircon covers, while others contain push tabs, depending on your AC unit type. Set aside the AC cover and remove the filter’s clips that lock it in fix position or slide your filter out. 

Check and ensure that your aircon’s filter is washable and not disposable because disposable filters need replacement after a specific time frame. You can review your manual to identify what type of filter your unit has before going to the next step.

Step 2: Use a vacuum for the filter

To prevent dust from outspreading in your room, take your air conditioner filter out. Utilize a vacuum at a low or medium setting, and then run it in an upward and downward motion to get rid of visible grime and dust from the filter. 

Remember not to press too hard on the frail filter because it may have a tear or dent. Carefully hold the filter in one hand as you use the vacuum with the other one. 

Step 3: Plunge the filter into the water

After you vacuum the filter, fill a container or tub with lukewarm water, and then put some liquid detergent in it. Mix the solution well to make it foamy, and plunge the filter into the water. To completely cover it with soap and foam, move the filter around the container. 

It is not advisable to utilize abrasive tools like wires or brushes to scrub your air conditioner filter because it is delicate and may get damaged. Wait for around 10 to 15 minutes before getting the filter out from the container.

Another option for this method is to hose the filter’s one side entirely until the dirt falls out. Do the same way to the filter’s other side until clean water already drips out of the filter. 

Spray the solution into the filter

Step 4: Spray the solution into the filter

Create a solution by mixing equal parts of water and vinegar, then put it inside a spray bottle. Spray the water and vinegar solution to both sides of the AC filter. Set the filter aside for about 10 minutes to eliminate the harmful bacteria before putting it under running water. 

Step 5: Air-dry the filter

Put several dry newspapers on a clean surface or ground, and then place the filter on top of them against the wall. Air-dry it first for some hours before installing it back on the air conditioner, then close the AC cover. Lastly, turn on the unit and enjoy a cool airflow.

When the AC filter is too large, it will not fit, and if it is too small for the system, there will be gaps where small particles can go through. Get the depth, length, and width to identify the right size, and then round up to its nearest inch.

  1. MERV rating

Another factor you can consider is the MERV rating on your air conditioner filter. MERV stands for Minimum Efficiency Reporting Value, which is the primary rating system in the HVAC industry. Generally, the lower the MERV rating, the cheaper the aircon filter. 

MERV rating ranges from 1-16. You may want to search for a rating between 7 and 13 to obtain optimal efficiency in your residence.
