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 North reusable respirator combination cartridge/filter is for use with Air Purifying Respirator. When properly fitted these cartridges protect against Organic Vapors and may be used without restrictions in atmospheres that contain oil based aerosols. The addition of the P100 prefilter adds protection against all particulates.
