Fill a bucket with water at a temperature between 50 to 65°C (between 122 to 149°F).
Add the laundry detergent to the water according to the manufacturer's directions.
Immerse the dirty filter in the bucket.
To let the water flow through the filter, gently agitate the filter for approximately two minutes.
Let the filter soak in the water for 15 minutes.
Turn the filter upside down.
Agitate the filter again for approximately two minutes.
Remove the filter from the water.
Follow local guidelines to dispose of the dirty detergent solution.
Using the empty bucket or a new bucket, fill it with clean hot water.
Rinse the filter in the bucket by agitating the filter for one minute.
Remove the filter.
Air dry the filter, making sure it is protected during the drying process. It may take the filter three to four hours to completely dry.

Cleaning the pleated filter
Follow these steps to clean the pleated filter.
Remove the pleated filter from the product.

If the filter has any damage such as bad gaskets, dented metal parts, or torn media, dispose of it.
Using compressed air (100 psi maximum), blow the loose surface dust off the filter, blowing from the inside out in the opposite direction of the arrow to prevent forcing the dust into the media pores.
