Recommended cleaning methods
The following methods (listed in order of ascending efficiency) can be used to
clean air filters:
1. Vacuum clean: A few passes of a vacuum cleaner remove accumulated
dust and dirt in seconds. Point the air nozzle in the direction of operating
airflow (vacuum from intake side toward exhaust side).
2. Blow with compressed air: Point a compressed air nozzle in the opposite
direction of the operating airflow (blow from the exhaust side toward the
intake side).

:
Oily residues and moisture reduce cleaning efficiency
of the above methods; in such cases, clean the filter using
method No. 4, or replace the filter.
3. Cold water rinse: Under normal service conditions, the foam media used
in the filters require no oily adhesives. Therefore, collected dust and dirt
can be washed away using a standard hose nozzle with plain water. Stand
the filter until completely dry and free of moisture, and return to service.
4. Immersion in warm soapy water: Where stubborn airborne dirt is present,
the filter may be dipped in a solution of warm water and mild detergent.
Then simply rinse in clear water, stand until completely dry and free of
moisture, and return to service.
The recommended method is No. 4, as it ensures thorough cleaning of all types
of contaminants under any reasonable service conditions.
