What Dirty AC Filters Bring and How to Clean Them

To maintain healthy indoor air quality, you need to have your air conditioning unit cleaned regularly. And the easiest task homeowners can do in maintaining their AC unit is cleaning or replacing its filters. 

Regular filter upkeep is crucial in keeping the good air quality in the room and keeping the unit in good condition. Air conditioner services are also a must to maintain the unit and avoid serious problems in the long run.

But what makes the AC filter get easily dirty? Why will a dirty AC filter potentially become a big problem to homeowners? In this article, you’ll discover things you need to know about dirty AC filters and all the ways you can clean them. Read on.

How Filters Work in An Air Conditioning Unit

It is commonly known that an air conditioner can trap many harmful substances inside it as its system regularly works. These harmful elements can affect and mess with the operation of any of the unit’s components. The filters serve as the controlling component of the AC unit that protects the system against these contaminants, and they are why your unit keeps working smoothly and efficiently.

As the filter catches dust, dander, hair, and other allergens to keep the system going, all of these elements accumulate on it as time goes by. And once it gets dirty, an aircon filter can start causing problems to the entire unit. 

For one, it will force the system to work doubly hard to produce cool air to keep your home at the desired temperature level. In effect, homeowners will get a higher electricity bill since the unit consumes more energy. This also strains the entire system, leading to a component breakdown and other similar issues. The AC unit will likely have a shorter life span if the system is continually strained in the long term.

Why You Need to Clean Your AC Filter Regularly

As mentioned above, dirty filters cause strain to the unit, higher electricity bills, and shorter AC unit lifespan. To avoid these consequences, cleaning the filter regularly will keep your AC unit functioning well without problems. 

But aside from the integrity of your unit, there are other important reasons why cleaning your aircon filter regularly is necessary. A clogged filter can potentially cause several health problems to your household. Harmful elements trapped in the filters can mix with the air. The indoor air quality will significantly drop, and health risks will start to loom larger. 

Allergies, skin rashes, and respiratory ailments are some health issues homeowners can get from a dirty filter. With this in mind, you should be mindful of keeping the AC filters clean and free from harmful elements, securing clean and safe indoor air quality.

Factors to Consider in Changing Your AC Filters

Now the question is: what are the things you should know and consider when changing your AC filters? 

Your aircon manufacturer can give you ideal recommendations as to which filter to use—many different kinds can be bought in the market for a certain price.

Filters are used for different functions. Some are designed to filter out some allergens, while others are developed for multiple uses to have an easier AC filter cleaning and maintenance. Another type of filter is one that traps smaller particles that regular filters do not catch. Based on your unit’s model, decide which is best for you and your needs.


Regular aircon filter maintenance is crucial in keeping the unit properly working, keeping your room cool, and avoiding potential health risks. With this guide, you can keep your AC filter clean and your family healthy!
