Replacing the filter
•
All filters and cartridges must be replaced when the LED indicator is illuminated red.
The red LED and audible alarm indicates that the HE (HEPA) filter material is plugged
or blocked to the degree where Pureflo ESM+ can no longer provide sufficient airflow
to the respirator user.
•
Install the new filter as show in Section on page. Twist the filter counterclockwise to
engage the thread and then tighten clockwise to fit the filter onto the respirator.
•
The Pureflo ESM+ has no end of service life detection (gases and vapors)
•
Replace cartridges for protection against vapor/gases according to your employers
change out schedule or sooner if contaminant is detected within the breathing zone
of the respirator.
•
Never attempt to clean the HE filter cartridge by knocking or blowing out
accumulated material. Doing so will damage the filter media.
