Replace the cartridge on your respirator when breathing becomes difficult.

Attach a compatible 3M or Moldex filter to respirator cartridges.

As you breathe through them, these respirators filter out contaminants in the air. Throw them out when soiled, damaged, or breathing is difficult.

Make it easier to move and more comfortable to wear your respirator.

Replace worn or damaged breathing tubes—these tubes deliver clean, breathable air from the air pump to your hood or helmet.

Remove at least 95% of particles from the air your blower sucks in, so your respirator has clean air.
