HEPA Filter Leak Test Preparation & Safety Precautions
Before initial use, or after a HEPA filter change, it is recommended to verify the integrity
of the supply and exhaust HEPA filters. This test will check for leaks in each HEPA
filter. This test should only be conducted by a trained certifier, preferably one who is
NSF accredited.
This section describes the preparation, tools, and safety precautions required to
challenge each HEPA filter in the enclosure.
The following tools are required:
• Aerosol Generator
• Photometer
• Ladder (6-ft tall minimum)
• Phillips Screwdriver
• 5/16" Wrench
During this test, the blowers must be on and running at a stable level (generally when
the Please Wait notification is dismissed from the display, which is about 90 seconds).
While scanning the supply HEPA filter, the Front Hatch will be open. When the blowers
are on, this will generate a Sash Alarm. Press
mute the audible alarm tone for 5 minutes. If the audible alarm returns, simply press the
button again to mute for another 5 minutes.
You never know what a HEPA-filtered enclosure has been exposed to, so it is always
recommended to surface decontaminate any components prior to working inside the
enclosure and/or removing components from the enclosure.
