How to Clean a Holmes HAPF30 HEPA Filter

Updated November 21, 2016

The Holmes Company manufactures a variety of heating and cooling supplies and equipment, including humidifiers, heaters, fans, air purifiers and filters. The Holmes HAPF30 HEPA filter is meant for use with Holmes brand or Bionaire air cleaners. These filter out impurities from the air that is drawn inside the machine. The HAPF30 air filter can be purchased online or in many hardware or home repair stores and should be cleaned every 12 to 18 months, in order to keep the machine working at peak performance.

Turn off the air cleaner and unplug from the electrical power source. Open the front access panel, unhook the clasps holding the filter in place and slide it out of the HAPF30 filter.

Shake the filter over a waste bin and use a soft bristled brush to gently brush excess dirt and debris from both sides of the filter. Be cautious. Do not rip or damage the filter.

Place the filter in a large sink and rinse it with lukewarm water. Rinse well until no dirt or debris is evident. A garden hose can also be used, as long as care is taken not to blast the filter with a strong spray of water, thereby damaging it.

Allow the filter to air-dry completely, which typically takes several hours.

Slide the filter back in to the air cleaner and clip back into place. Close the front access panel and plug the unit back into the power supply.


Replace the HAPF30 filter if the filter is torn, cracked, damaged or excessively dirty and cannot be cleaned.
