Instructions

Access The AC Filter: First, locate where your car’s air conditioning filter is located. This may vary depending on the model of vehicle you have. Once found, unscrew or unclip the filter and remove it with care.

See Manual First: It is always best to refer to the car’s user manual before cleaning. Most newer model AC filters are washable and must be removed from the unit for a thorough cleaning.

Brush Away Dust & Dirt: Remove dust and dirt using an old brush or soft-bristled toothbrush. Keep the filter upside-down, so the dirt falls into a container or bucket. This will ensure that no dirt flies back into the AC unit and leaves it clean while brushing away dust and debris.

Vacuum: Using a vacuum cleaner, suck up any remaining dust and debris from the filter and the unit itself.

Clean The Filter:

• Use a microfiber cloth to remove any remaining dirt from the filter.
• Take your mild detergent or antibacterial soap, add it to a bucket of warm water and submerge the filter in it for 10-15 minutes.
• Do not use abrasive products or harsh chemicals, as this could permanently damage the filter.

Rinse And Dry: Once the filter has been submerged in soapy water, use a hose to rinse off any soap residue. Make sure to completely dry the filter by patting it down with a microfiber cloth or towel.

Replace: Replace the filter into its slot and secure it with the screws or clips. Check the user manual for instructions on securely installing your air conditioning filter.
