Description

Good to know

• What does ABEK1 mean? In ABEK1, A covers organic vapours, B inorganic gases, E acid gases such as sulphur dioxide and K ammonia; class 1 is the lower-capacity grade.
• Do they stop dust or spray mist? No. ABEK filters are for gases and vapours; they do not stop dust or paint spray mist on their own, which needs a particle (P) filter.
• When should I change them? Change gas filters as the maker's instructions say, and at once if you can smell or taste the substance; keep spares sealed.

Which one?

These need a mask: Portwest list the P500 full face mask and the P420 and P430 half masks, and the Portwest P421 TPR Half Mask (P421GRRM/L) lists P921 among its filters.
