Why Cleaning Your AC Filter is Important

A dirty air conditioner filter can reduce airflow, increase energy consumption, and circulate dust and allergens. Regular cleaning improves efficiency and indoor air quality.

How Often Should You Clean Your AC Filter?

• Every 2 weeks if you use your AC frequently.
• Once a month for moderate use.
• More often if you have pets, allergies, or live in a dusty environment.

Step-by-Step Guide to Cleaning Your AC Filter

Step 1: Turn Off the AC

For safety, always switch off your air conditioner before removing the filter.

Step 2: Locate and Remove the Filter

• Check your user manual if unsure.
• Most filters are behind the front panel of a wall-mounted unit or inside a return vent for central AC.

Step 3: Vacuum the Dust

• Use a handheld vacuum or brush attachment to remove loose dust and debris.

Step 4: Wash with Water and Mild Soap

• Rinse under lukewarm water.

Step 6: Reinstall and Turn On the AC

Once the filter is dry, place it back in its slot and turn on your AC.
