Things You'll Need
Pollen mask or respirator
High efficiency particulate aerosol (HEPA) filters are used in a variety of ways to remove particles, dirt, dust, allergens and even some forms of bacteria from the air. HEPA filters have become common in household vacuums and carpet cleaners, as well as in construction, air purifiers and other units that filter air in a home or business. Most HEPA filtration systems also use other filters as well to remove as many particles as possible from the air. HEPA filters should be replaced on a regular basis and the old HEPA filter should be discarded properly.
Wear protective clothing, gloves and a pollen mask or respirator, since the used HEPA filter may be extremely dirty, dusty or even toxic.
Turn off and unplug the device in which the HEPA filter is installed.
Remove the filter housing and any pre-filters from the device.
Remove the HEPA filter by grasping the outside corners of the unit and placing it in a large, sealable bag. Seal the bag closed.
Discard the bagged HEPA filter in an outdoor waste container or contaminated waste receptacle, if available.
