NIOSH Items: We only sell brand new respirators, filters, and dust masks from US based manufacturers. Since it can be difficult to determine if a respirator or mask has been used or even just tried on, for the protection of our customers, we do not accept NIOSH returns.
The 3M 502 filter adapter allows you to add a P100 particulate filter on top of a 3M chemical or organic vapor cartridge. The 502 is compatible with the 3m 6001, 6003, 6004 and 6006 cartridges that we have listed on our site. The P100 rated 2000 series filters and the P100 rated 7093 filters will both fit this adapter. Simply snap the 502 adapter on top of a cartridge, and then attach a filter to it with a 1/4 turn.
This item is sold 20 each per box.
