## Description

The 3M 6391 Half Facepiece Respirator Assembly includes the 3M Half Facepiece Respirator 6300 and 3M P100 Particulate Filters 2091. Helps provide respiratory protection in environments containing certain oil and non-oil based particles. This assembly includes a 3M 6000 Series Half Facepiece Reusable Respirator and two 3M 2091 P100 Particulate Filters. This assembly is NIOSH approved for environments containing certain oil and non-oil based particles. When properly fitted, this respirator helps provide protection in a variety of applications including welding, brazing, torch cutting, metal pouring, soldering, and exposure to lead asbestos, cadmium, arsenic, and MDA at concentrations up to 10 times the Permissible Exposure Limit (PEL). This respirator is remarkably comfortable, soft, and lightweight, and features easy-to-adjust head straps. The swept-back design of the cartridges helps improve balance and visibility. Easy-to-adjust head straps allow for a customized fit to the user. When used to capacity, the included cartridges can be removed and replaced with new P100 Filter/Cartridges or other NIOSH approved 3M 2000 or 2200 Series Filters or 6000 Series Cartridges. The respirator can also be disassembled, cleaned, and reused, extending the life and cost effectiveness of the product. NIOSH, a Federal government regulatory agency, has tested and approved the 6000 Series with 3M cartridges, filters or supplied air systems to help reduce breathing certain airborne contaminants. The 6000 Series is NIOSH approved for negative air purifying and positive pressure dual airline applications. The respirator comes with a P100 filter, which is replaceable. This half facepiece respirator may be used with any of these replacements: 3M Cartridge 6000 Series; 3M Filters 2000, 2200, 7000 or 5000 Series; or 3M Dual Airline Systems against a variety of gases, vapors, and particulate hazards according to NIOSH approvals. Breathing hazardous particles, gases and vapors can be harmful to your health. The 3M half Facepiece Reusable Respirator 6000 Series helps reduce exposure to many contaminants.

Review: Comfortable fit, excellent air exchange - I purchased three of these masks for my family during this summer's wildfire season, which unfortunately continues to burn only 8 miles away from my home. These 3M Half Face-piece Reusable Respirator Assemblies make the smoke bearable. The fit is snug, but not tight and can be adjusted to fit different face sizes. The feel of the mask becomes more comfortable over time than surgical-type masks, which tend to lack suitable air exchange which holds in vapor (ie: sweat). The filters which are pictured on the side of the respirator (pink in the picture, but we received blue ones with our masks), are easy to attach to the mask. You will need to purchase new filters as these get soiled, but the price is reasonable. Notches on the respirator correspond with those on the filters and it's a matter of lining them up and twisting them on. The connection is very secure and the filters do a great job. These respirators are superior to the basic paper face masks, and obviously work well enough to be used in multiple situations, for multiple uses. I would recommend these masks to anyone who needs a step above the basic filtration that a 3M 1860S Particulate Respirator and Surgical Mask, Small, Box of 20 provides. People with asthma, COPD, the elderly, children and those with autoimmune diseases would benefit from using this mask in smokey conditions. Under normal circumstances, those who are into crafting and woodworking, using sanders, paints, and varnishes, would also find this respirator assembly a helpful safety basic. These masks do come in sizes (S,M,LG). I purchased 3 of the medium size, and it seems to fit everyone (all average sized 5'4-5'10, average weight), just fine. I highly recommend this quality 3M product.
