Step by Step Guide To Clean Ducted Air Conditioner Filter

Step 1: Switch the Power

First, switch off the power to ensure no one will be injured during this procedure. Then, using a flat head screwdriver, push it upwards into the slot above your switchboard. After that, just go around and flick all the switches from “On” to “Off.”

Step 2: Remove the Filter Cover

After that, it’s time to remove the filter cover. It won’t be too difficult since all you need is a flat head screwdriver and a pulling tab by your side (which you can attach with tape since usually, they are pretty stuck). You should see something like this once you’ve removed the filter cover.

Step 3: Remove the Filter Enclosure

It’s time to remove your filter enclosure by pushing on those four tabs, as shown in the picture below. They should come off quite quickly, so if they don’t, just make it a bit harder until it pops out as mine did. It looks something like this once you’ve removed it.

Step 4: Wash Out the Dust & Dirt

Now, all you have to do is wash out the dust and dirt accumulated inside your filter enclosure. You can use some water pressure; a hose or even a bucket will work. Usually, most of the dirt gathers around all edges, so try to get in there with your hose. Once you’ve washed it out, simply put everything back together in the reverse order and switch on the power.

Step 5: Clean the Shaped Fiberglass Filter

Now, this step is optional; if you only have the fabric filter, you can skip this part. If, however, you have one of those shaped fiberglass filters, it’s time to clean it with water pressure again by using a bucket or hose-like. Just ensure that no little bits are getting into the air duct that goes into your house.

Step 6: Clean the Stove Duct

If you have a stove duct, clean it with water pressure again by using a bucket or hose, but don’t get any bits of fiberglass dust running inside your home because they stick to carpet and furniture like glue!

Step 7: Close Up

Now, all you have to do is put your filter enclosure back in place, ensure the sealing clips are attached and close up your filter cover. After that, it’s time to enjoy an excellent clean filter! Mind you, most of the time, it only takes 5-10 minutes from start to finish.

Step 8: Enjoy A Cleaner Home

Enjoy the fact that your filter enclosure is all clean, and enjoy your cleaner home. Now, if you own an air conditioner, then this is done slightly differently than when you own a heater. Usually, the filter is located behind your air conditioning unit and situated at about head level. So now that you’ve got your filter clean, enjoy cleaner air flowing through all the time!
