In this post, I’ll show you how to clean an activated carbon air conditioner filter by using baking soda and dish soap.
I have been using this method ever since I bought my Carrier Optima A/C. That was more than 2 years ago already, and the filter is still working as it should.
So let’s dive right in.
What you’ll need:
Baking soda
Dish soap
Warm water
Soft brush
Laundry basin or sink
Steps on How to Clean your Activated Carbon A/C Filter with Baking Soda
Step 1: Brush off dust build-up
Remove dust build-up by scrubbing the filter with a clean brush. You can also use your vacuum cleaner for this.
Step 2: Make the Baking Soda and Dish Soap Solution
Mix 3 tablespoons of baking soda and 1 tablespoon of dish soap per liter of water. Make sure the water is warm and NOT hot. Stir them together until you create some suds.
Step 3: Soak the a/C filter in the solution
Let the filter soak for 30-40 minutes. This will give the solution enough time to soften and remove some of the dust build-ups.
Step 4: Scrub the filter with a brush
Use a brush to remove any remaining dust. Scrub gently so you don’t destroy the fibers of the filter.
Step 5: Rinse with water
Put the filter under a running faucet and rinse well. You can also use a water hose. Make sure to rinse off any remaining traces of soap and baking soda.
Step 6: Air-dry the filter
Finally, air-dry the filter. You might be tempted to use the dryer, but don’t do it. Exposing the activated carbon filter to high heat can make it brittle.
How Often Should You Replace An Activated Carbon A/C Filter?
According to Mr. Raul Santos, an air conditioner technician, you should replace your air conditioner filter every 2-3 years, depending on how often you use your A/C. If your air conditioning is turned on for more than 8 hours every day, replace the filter every 2 years.
Another factor that also affects the lifespan of your A/C filter is how dusty the place you live in. As a rule of thumb, if your filter starts to look worn out and the air coming out of your AC smells strange, then it’s time to replace the filter, according to Mr. Santos.
4 Reasons why You should keep your air conditioner filter clean
- You Save Power. A clean filter makes your air conditioner run more efficiently lowering your power consumption. Lesser power consumption equals lower electricity bills.
- Fewer Allergies. A dirty air conditioner filter can spread air-borne allergens.
- Longer A/C life. The back of the aircon gets too hot when the filter is dirty. This can shorten the lifespan of your air conditioner.
- Cooler Air Coming Out of Your Air Conditioner. Dust build-up on an A/C filter can block the airflow, so it’s essential to keep the filter clean if you want to maximize your A/C’s cooling power.
