Typical Applications

Industrial Maintenance


What is the difference between a respirator and a standard face mask?

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.

What is a NIOSH Approved Respirator?

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

How long do particle filters last?

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.
