What is the shelf life of 3M
™
Filters?
Provided they are stored unopened in the original
packaging, filters will last five years from manufacture
date. Once removed from their packaging they should
be replaced after six months as recommended by
Australian/New Zealand Standards (even if they have
not been used).
How should I store my 3M
™
Reusable Respirator
and filters?
When not in use, your 3M™ Respirator and Filters should
be kept clean and dry, and away from oil and sunlight
and corrosive atmospheres to avoid deterioration. A
storage container or bag that can be sealed, can be utilised
for this purpose.
Why do I need to use a Particulate Filter with my Gas &
Vapour Cartridge Filters for some applications?
The particulate filter removes the tiny droplets or particles
in the air (e.g. mists from spray painting). The gas and
vapour cartridge filters do not filter these particles. If no
particulate filter is used, they could be breathed in.
What is a Fit Test?
Because everyone’s face is different, a fit test is used to
determine an adequate match between the face piece
of a respirator and the face of the wearer. Ideally this
should be done before the respirator is first issued and
then at regular intervals.
Can I wear a respirator with a beard?
Any facial hair has the potential to break the face seal
of a respirator. We recommend that people wearing
respiratory protection be clean-shaven, to enable the
respirator to achieve a good seal against the face.

The service life (i.e. how long it will last) of any gas
and vapour cartridge filter is affected by many factors
– some being: concentration and identity of contaminants,
breathing rates, humidity levels, ventilation, temperature,
carbon exposure time etc.
Replace both the 3M
™
Gas & Vapour Cartridge Filters:
• When the expiry date stamped on the sealed packet
has elapsed.
• Once opened, maximum use time is 6 months (even if
not used). The carbon will absorb contaminants from
the general environment.
• When contaminant can be detected by smell or taste.
• Or in accordance with your established Filter
Change Schedule.
To avoid smelling or tasting the contaminant when
using 3M
™
Gas & Vapour Cartridge Filters, take the
following steps:
• When you get a new pair of 3M Gas & Vapour
Cartridge Filters check the expiry date on the back
of the pack.
• Write the date on the filters when first removed
from the pack.
• Use the filters on your respirator in your normal
work environment.
• If at any time you smell or taste the contaminant
or irritation is detected, the filters need replacing.
• Take note of how long the filters lasted by comparing
the date recorded on the filter and the current date.
• If work practices remain the same and the levels of
vapours/gases are consistent, replace your filters on a
more regular timescale.
• Or in accordance with your established Filter
Change Schedule.
