The rate of accumulation will depend upon the
cleanliness of the room air, the amount of time the
enclosure is operating, and the nature of work being
done. With normal usage, the HEPA filters will last
two to five years before requiring replacement.
Each HEPA FilterMate is provided with a disposal
bag for proper disposal. Follow the HEPA Filter
Bag-In/Bag-Out procedure in Chapter 5 for disposal
instructions.
Misapplications that could
result in a hazardous
situation (Volatile Chemicals)
There is one scenario where the FilterMate misapplication would
be a part of a hazardous condition. If the user continues to operate
the system with any of the following conditions present a
potentially hazardous condition will exist:
1. The inlet concentration of vapors is greater than the TWA.
2. The carbon filter becomes saturated.
3. The ventilation of the room is insufficient to dilute the exhaust
of the FilterMate to below the TWA for the chemical.
When the inlet concentration is greater than the TWA, extra
measures must be taken to monitor the filter and number of room
air exchanges.
