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