High energy particulate air (HEPA) filters are used to collect the fine particles of dust, dander and other allergens that other filters cannot. This improves the air quality in your home and reduces allergy and asthma symptoms.

Many vacuums have a HEPA filter.

These filters can be used on vacuums, air purifiers and in the central heating and air conditioning of your home. From time to time, you need to replace or clean HEPA filters in order for them to function properly. It is important to know how to was a HEPA filter properly, otherwise you may damage it.

  1. Put on an air filtering face mask before you clean your HEPA filter. This is of particular importance if your have allergies and/or asthma.

  2. Remove your HEPA filter from your vacuum or air purifier. If you are cleaning your vacuum HEPA filter you will need to empty the dust cup for your vacuum.

  3. Rinse the other removable parts of your vacuum or air filter. You can also wipe the housing of your air filter with a moist paper towel to remove any surface dust and grime.

  4. Rinse your HEPA filter under a steady stream of water. Turn and rotate the filter under the water to remove the loose surface layer of dust and grime.

  5. Scrub your HEPA filter gently with a scrub brush, while holding it under the stream of running water. This will help remove any dust or grime that is more stubborn and set in.

  6. Wipe away any excess moisture on your filter when you are done scrubbing it. Sit it on a layer of paper towels and allow it to air dry before putting it back in your vacuum or air purifier. Turn it over mid-way through drying, so both sides dry evenly.
