How do I dispose of a used HEPA filter?


High Efficiency Particulate Air (HEPA) filters are used in biological safety cabinets (BSCs), laminar air flow clean workstations, and other air handling equipment to provide clean work environments. In the case of BSCs they also provide worker and environmental protection by removing contaminants from the air. When a HEPA filter is changed, the proper disposal of the used HEPA is always a concern. HEPA filters from laminar air flow workstations and other product protection applications may only filter room air therefore filters may contain only the normal particulates found in air. These filters are typically not viewed as being contaminated and can be disposed of as non-regulated waste.
