This filter is the final filtration stage of the HEPA ZONE 24 air scrubber. It captures the vast majority of fine particulates that have not been stopped by the prefilter. Specifically, it captures 99.97% of particles of size 0.3 µm or greater, such as bacteria, mold spores, soot, pollen, pet hair, pet dander, dust mites, smoke particles, allergens, and any other hazardous airborne particles.

The filter is made of a folded fiberglass sheet within a metal frame. When the HEPA filter is saturated by captured particles, the air scrubber motor must work harder to push air through the filter. This can lead to dangerous overheating. Therefore, preemptively replacing the HEPA filter helps extend the air scrubber service life. The manufacturer recommends replacing the HEPA filter every 9000 hours of use or after 18 months, whichever comes first.

This filter may also be used with air scrubbers other than the HEPA ZONE 24 work enclosure, if they are compatible with the filter format.
