A clean filter is the easiest way to keep your AC cooling well. It takes about ten minutes and needs no special tools. This guide covers a typical split AC; always check your user manual for your model.
Before you start
- Switch the AC off and unplug it or turn off the MCB.
- Keep a soft brush, a vacuum cleaner with a brush attachment, lukewarm water and mild soap ready.
- Use a stable stool so you do not have to stretch.
Step by step
- Open the front panel of the indoor unit by lifting it gently from the sides.
- Slide the filters out carefully, noting how they fit back in.
- Remove loose dust with a vacuum or by tapping gently outdoors.
- Wash in lukewarm water with a little mild soap. Use a soft brush for stubborn dirt.
- Rinse and dry fully in the shade. Do not use hot water, and do not refit a wet filter.
- Refit the filters and close the panel properly.
How often?
When the AC is in daily use, check the filter every two to four weeks. In dusty surroundings or near construction, check it more often. Learn more about servicing frequency in how often you should service your AC.
What not to do
- Do not spray water inside the unit.
- Do not touch the cooling fins; they bend and cut easily.
- Do not run the AC without the filter fitted.
When to call a professional
A clean filter will not fix dirty coils, a blocked drain or a bad smell. If your AC still cools poorly or smells musty after the filter is clean, a deep clean is the next step. You can book AC cleaning in Greater Noida to have the indoor and outdoor units cleaned properly.
Frequently Asked Questions
How often should I clean my AC filter?
During heavy use, every two to four weeks is a good habit. In very dusty conditions, check it more often.
Can I use hot water or a brush on the filter?
Use lukewarm water and a soft brush at most. Hot water and harsh scrubbing can warp or damage the mesh.
Is cleaning the filter the same as AC servicing?
No. Filter cleaning is basic upkeep. A full service also cleans coils and the drain, and checks the electrical parts.
