Cleaning an air filter fan involves cleaning the filter itself. The cleaning method depends on the type of filter.

Understanding Your Air Filter

Before you start, identify what kind of filter you have:

  • Washable Filters: These are designed to be cleaned and reused.
  • Non-Washable Filters (e.g., Permanent HEPA filters): These should not be washed with water, as it can damage them.

Cleaning Washable Air Filters

  1. Remove the Filter: Turn off and unplug the air filter fan. Carefully remove the filter according to the manufacturer's instructions.
  2. Vacuum Loose Debris: Use a vacuum cleaner with a brush attachment to remove any loose dust and debris from the filter.
  3. Wash the Filter:
    • Rinse the filter with clean, lukewarm water.
    • If the filter is extremely dirty, you can soak your filter in hot water.
    • You can also use a mild detergent, but be sure to rinse thoroughly to remove all soap residue.
  4. Dry the Filter Completely: Allow the filter to air dry completely before placing it back in the fan. Never put a wet filter back into the unit.
  5. Reinstall the Filter: Once dry, reinstall the filter according to the manufacturer's instructions.

Cleaning Non-Washable (Permanent HEPA) Air Filters

  1. Remove the Filter: Turn off and unplug the air filter fan. Carefully remove the filter according to the manufacturer's instructions.
  2. Vacuum the Filter: Clean non-washable, permanent HEPA filters using a vacuum to remove dust and debris. Use a brush attachment to gently vacuum both sides of the filter.
  3. Reinstall the Filter: Reinstall the filter according to the manufacturer's instructions.
    *It is important to know that cleaning these permanent HEPA filters with water can cause damage, as these types of filters are not designed to come into contact with water.

Important Considerations:

  • Frequency: Check your air filter regularly (e.g., monthly) and clean it as needed. More frequent cleaning may be necessary if you have pets or live in a dusty environment.
  • Replacement: Even washable filters have a lifespan. Replace your filter according to the manufacturer's recommendations.
  • Manufacturer's Instructions: Always refer to your air filter fan's manual for specific cleaning instructions.
