Can the medium efficiency filter be repeatedly cleaned?
Can I clean the filter?
Permanent or washable HEPA filters can be cleaned and reused many times, as long as it is done correctly and does not damage the filter.
The most permanent HEPA filters can be gently vacuumed, while washable HEPA filters can be cleaned with a cold water rinse.
The most common method of cleaning HEPA filters is to use a vacuum cleaner brush attachment. The speed is set to minimum and the vacuum gently vacuums the surface of dust, hair and mites without applying pressure to the filter material. Another method is to rinse it with cold water to relax all the trapped particles. Allow the HEPA air filter to air dry completely (usually one day) before inserting it back into the unit. You can also get rid of excess moisture to reduce drying time. Ultimately, follow whichever manufacturer's recommended method includes any special instructions on how to clean the HEPA filter. If not, the general guideline is that a true HEPA filter should be disposed of and replaced rather than cleaned.
When you do, remember:
Wear a mask to reduce your risk of directly inhaling contaminants that have escaped.
Getting the outside filter cleaned is the best way to reduce the amount of air pollutants being introduced into your home.
Permanent HEPA medium efficiency filters rarely come in. Usually pre-filters and activated carbon filters. These should be removed and cleaned.
Pre-filters can be rinsed with water, under a faucet, and continued until the water runs clear. The fine line filter should be cleaned gently with a soft brush. You can also use a damp sponge to wipe both sides of the filter.
Activated carbon filters should be gently cleaned with a vacuum cleaner to remove dust and dirt. Clean both sides with a vacuum using a horizontal motion. If the carbon filter absorbs a lot of odor, you can leave it in direct sunlight for an hour or two.
If you wash the foam or carbon carry out towel drying and allow 24 hours to dry completely
