Respirators allows for a higher filtration efficiency and better fit than standard face masks. All respirators must be approved by CE/NIOSH with an assigned approval code on each respirator if you’re unsure about a respirator or a standard face mask.

The NIOSH regulates the manufacture and testing of respirators, along with cartridges, filters and supplied air systems.

As particle filters load up with the contaminant they actually become a better filter. However, they become a harder filter to breathe through. The user will notice breathing becoming too hard and will then need to change the filter.

2000 series filters fit directly to the masks. 5000 series particle filters fit to 6000 series anti-gas filters using a holding ring, ref. 501
