Listed below are suitable applications for HEPA filters. 

HEPA Filter Applications, 

Suitability and Guidelines 

• 

Procedures traditionally performed on an open bench where a 

clean Class 5 air environment is now required. 

• 

The HEPA filtered enclosure provides product protection from 

particulate matter.  Because air from the enclosure enters the 

room during operation, this enclosure should only be used for 

operations requiring sample protection from environmental 

contamination. 

• 

HEPA filters are only effective for entrapment of particulate 

matter.  The surface of the HEPA filter is fragile and should 

not be touched.  Care must be taken to avoid puncturing the 

HEPA filter during installation.  If you suspect that a HEPA 

filter has been damaged, DO NOT use the enclosure. See 

Chapter 6 for Replacing the HEPA Filter. 

• 

The HEPA filter will gradually accumulate airborne 

particulate matter from the room.  The rate of accumulation 

will depend upon the cleanliness of the room air, and the 

amount of time the enclosure is operating.  With normal 

usage, the HEPA filters will last two to five years before 

requiring replacement.
