The HEPA filter media is very fragile. DO NOT touch the media. If
you think the media of a HEPA filter is damaged, DO NOT USE THE
CABINET. Have the HEPA filter integrity tested by a certifier before using
the cabinet.

HEPA Filters are only effective against particulate material. Gases will
pass through the filter.
