Respirator Cartridges, Gas Filters and Particulate Filters

Respirator cartridges and filters must match the airborne hazard. This range includes organic vapour, acid gas, multigas, ABEK, AX, P2, P3 and combination filters for compatible APR or PAPR systems.

Quick guide: Choose filters from the SDS and exposure assessment. Filter colour, class and product name are helpful clues, but compatibility, service life, breakthrough risk and changeout schedule matter just as much.

Selection Guide

Filter type	Typical hazard	Selection note
P2 / P3 particulate filters	Dust, fumes, mists and particulates	Check filter loading and changeout
Organic vapour cartridges	Solvent and vapour exposure	Plan service life
ABEK / multigas filters	Mixed gas and vapour hazards	Confirm every contaminant
Combination filters	Particles plus gases/vapours	Check breathing resistance and compatibility

Standards and Procurement Notes

DOSH lists respiratory protective filters under standards such as EN 143, EN 14387 and BS EN 149 depending on product type. Verify approval, shelf life and compatibility before use.
