An optional nose clamp is included that can be glued on if difficulty is encountered getting a seal. The respirator fits 5P71 filters (P95 rating) and 5N11 filters (N95 rating).

The filter housing insert is glued into the face mask with superglue. M4 heat-set inserts or M4 nuts can be used for assembly, be sure to print the correct "Filter Housing Insert" depending on if you want to use heat-set inserts or nuts.
