Replacing the Filter Cartridge
The length of time the P100 filter will give protection depends on the concentration of the contaminant and the rate of breathing
while in the air-purifying mode of operation. [Service time can be extended by performing an evaluation in the specific
workplace setting that demonstrates (a) that the extended use will not degrade the filter efficiency below 95%, or (b) that the
total mass loading of the filter is less than 200mg.] When the face piece is properly adjusted, the following conditions are
indications that the filter has served its useful life and should be replaced.
P100 Filter
Excessive breathing
Cartridge
Resistance upon inhalation
The user should return immediately to fresh air if these conditions develop. Before attaching a suitable new filter, remove the
exhausted filter and examine the gasket in the coupling nut making sure it is aligned properly and undamaged. If misaligned the
seal must be adjusted. If damaged, the seal must be replaced.
WARNING!
Protection voided if sealing gaskets are misaligned or are damaged.
Failure to follow this warning can result in serious personal injury or death.
