Make sure none of the above solutions go inside of the filter, other than VHP which is the only known
decontaminant which can be used inside of the filter. Once cleaned with one of the above, rinse the
outside of the filter with plenty of water and leave to dry. Ensure products are dry before use or
storage.
At the very least, the filters should be cleaned at the end of each working shift to benefit personal
hygiene, health and product longevity.
SPECIFICALLY FOR THE USE OF PARTICULATE FILTERS IN AEROSOL GENERATING PROCEDURES
(AGPs):
It should be noted that
although our filters have been designed to prevent most droplets entering the
filter, there is the chance that some of the fluid will bypass this cover and reside on the pleated filter
material inside. This would be a call for your Infection Control department or Health and Safety Officer
as to how they would want to address this e.g., whether they would advise changing the filters more
often or disposing of the filter in such circumstances. However, should splashes contain
mucus/bacterial substances and this resides on the pleated material on the inside of the filter, then
we would advise filter change regardless. NB: Pre-filters may help to reduce the frequency of F1100
range filter changes in such instances. See section 3.4.5 for more information about pre-filters and
contact your Corpro Representative if these are of interest.
3.3.4 Storage
There may be particular required storage procedures depending on your working environment. This
should be confirmed with your organisational Respiratory Health and Safety Officer.
However, Corpro recommends the filters be stored in a cool, dry and sterile / uncontaminated place.
Corpro can offer rigid, reusable storage containers if this is preferable, but if not, somewhere safe and
clean such as a disinfected personal locker will be sufficient.
The filters should be always cleaned before storage, regardless of how long they may remain unused.
SPECIFICALLY FOR COVID-19:
NB: Make sure the mask and filters are dry in advance of storage.
Corpro recommends storing the filters (and mask) in a polythene bag, preferably zip-locked with some
form of desiccant (such as a dry silica gel sachet), when not in use. A polythene bag is included when
purchasing a HM1400 half mask or FFM1600 full face mask. If it not possible to store in such way, it is
suitable to store both the mask and filters in a clean area where there is no risk of contamination e.g.,
a disinfected personal locker.
