Choosing the right filters for your respirator/gas mask.
A look at the different types of filters available, Particulate (P) filters, NBC/CBRN filters and industrial ABEK filters.
NBC/CBRN filters are not all equal so it is important to realise what some filters can and can't protect you from.
ABEK is a good classification system as the label tells you what the filter can and cannot block.
A = Organic Vapours
B = Inorganic Vapours
E = Acid Vapours
K = Ammonia Vapours.
I made a mistake in the video where I refereed to Acid Vapours as C on the ABEK system, please assume I am saying E for the video to make sense.
If you want to find more details on a particular NBC/CBRN filter, most filter manufacturers offer a brochure on their website giving a list of what the filters can block. Some NBC/CBRN filters only offer ABE-P protection not the full ABEK-P3 protection.
