3.
Ensure the pre-filter and pre-filter holder are positioned in the same orientation as the F1100
range filter.
4.
Repeat for both filters on the mask. You can connect your pre-filter holder whilst the F1100
range filters are either detached from or connected to your respirator, although we would
advise attaching the pre-filters in advance of mounting the F1100 filters.
Step 2 – Doffing
1.
Turn the pre-filter holder anti-clockwise to remove from the F1100 range filter.
2.
Remove the pre-filter from the holder by sliding the pre-filter material away from the holder.
3.4.5.2 Shelf Life
Pre-filter itself:
If stored in its original packaging, in a cool, dry and sterile/uncontaminated place away
from sunlight, the shelf life is indefinite. However, should the product be removed from its original
packaging and/or be exposed to moisture, heat or dirt, this may affect the quality of the product and
the feasible shelf life would therefore reduce. Assess the apparent quality of the material on a regular
basis and respond appropriately.
Holder:
The holder has a shelf life of five years from purchase provided it is maintained and stored
appropriately (i.e., according to procedures outlined in section 3.4.5.3/3.4.5.4).
3.4.5.3 Cleaning and Disinfection
Pre-filter itself:
The product should not be cleaned / decontaminated.
Holder:
The holder can be cleaned in the same way as the HM1400 and FFM1600 respirators. Please
see section 3.1.3 for more information.
3.4.5.4 Storage
Pre-filter itself:
Store in a cool, dry and sterile / uncontaminated place, ideally in its original packaging
or in a sealed bag or container. Do not leave exposed to moisture, heat, sunlight or dirt.
Holder:
Should be stored in the same way as the F1100 range filters. Please see section 3.3.4 for more
