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.

It is approved for use with the following headgear: BE-10, BE-10BR, BE-12, and 6000DIN. Each unit sold is a case of 6 cartridges. Breathe Easy PAPR systems use 3 cartridges at a time, so this will give 2 full filter changes.
