3.5 Cleaning the filters
Remove filter from machine by following the steps in “Replacing the Filters”.
Note:
HEPA filters are NOT washable.
Gently tap filter to dislodge loose contaminants. Use a garbage bag or other suitable container to
catch the material, keeping in mind the type of material that was picked up during operation.
Rinse filter with warm, running water from the inside out.
Let filter soak for 10-20 minutes in warm water with a mild dishwashing soap.
Gently wash filter by rolling it through the water. A soft brush can also be used to clean the pleats,
but be careful to not tear the filter.
Rinse filter with clean, running, warm water and let air dry.
Note:
The filter must be completely dry before using again. Do NOT use compressed air to dry the
filter.
When filter is completely dry, re-install it on the machine.
Keep in mind that filters do have a life span and washing won’t get them back to like-new performance;
however, it will be better than using dirty filters. Inspect filters regularly for any damage to the filter
media. If the media is damaged, replace the filter.
