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 2071 is a P95 particulate filter to fit the 3M 6000 and 7500 Series masks. A P95 is intended for general purpose dust applications. Our customers use these when cleaning up the shop, sweeping a dusty warehouse or working in a dusty field. The idea is that it offers the same filtration as one of our dust masks, but with the good fit that you get with a half mask respirator. As you know, if the filter could stop the particle but it gets around the side because of a poor seal against the face, then the purpose has been defeated. The "P" indicates that this filter is "oil proof". By that we mean that oil mist, such as found in oil based paints, will not interfere with the electrostatic properties that the filter uses to trap particles. The "95" refers to the relative efficiency of the filter. This means 95% of particles that are .3 microns and larger will be trapped by the filter media. This would be used for most common dusts, including silica.
