HEPA 500 Filter (primary/internal)

Restore your DefendAir HEPA 500 air scrubber to the maximum capacity

HEPA 500 filters combine filtration ability with filter capacity.  To maximize HEPA filter life, be sure to change your prefilter (5W972 or F271) regularly.  You can double up your prefilter for the nasty jobs to further protect your primary filter from larger particulate.  Also now available is the new Activated Carbon Filter (F397) to deal with your nasty odor jobs.
