## Overview

The 3M 6391 Half Facepiece Reusable Respirator Assembly Kit combines NIOSH-approved P100 particulate filters with a lightweight, adjustable half facepiece respirator. Engineered for professional environments with oil and non-oil based particles, it offers superior protection, comfort, and durability. Its bayonet connection system and compatibility with multiple 3M filter series make it a versatile, long-lasting solution for demanding industrial and construction settings.

## 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.

Review: Good fitting and effective - It works, it fits, and it's comfortable. I previously had the medium size which kinda-sorta fit but I found I was constantly fiddling with it to make sure I maintained a good seal. With this one I put it on and forget about it. There is another type of mask that has a "drop down" feature, which means when you undo the clasps at the back the mask drops down off your face. That's handy if you want to pop it off for a minute to talk/eat/drink etc but it's not a big deal to lift this one out of the way if you need to. Some reviews commented on it coming without the filters. Mine came with the filters, as expected. Not sure if some people are ordering from third party sellers or what. I'm still using the filters that came with my previous respirator and they fit just fine. I wore my respirator for several hours while pulling down an elderly lath-and-plaster wall and some 1930s drywall. Previously I'd used a paper dust mask for that kind of work and found I got enough dust in my nose to be annoying. After some hours of pulling stuff down and cleaning up dust (including getting quite close to piles of dust as I swept them into a dustpan, prior to sucking up the remainder in a shop vac), virtually nothing got through. The very small amount that got through suggested I didn't have the mask fitted quite perfectly, but obviously it was pretty close. For my purposes I'm not hugely bothered if I don't have a perfect seal - my usage is more for building dust rather than specifically hazardous material. That said, this thing feels like it would stand up just fine if I was removing nastier material than plaster dust.
Review: 3M Stuff is Superior - Wonderful face mask. Filters very well & doesn’t leak & fog up glasses. Comfortable to wear for hours. Seems to last forever. I have one that’s over 25 years old & is good as new. Got another to get more filters & have a backup when I clean the inside of the other from runny nose or sneezing.

### ⭐⭐⭐⭐⭐ Great respirator.

As a welder, I've used these for years. My old mask was wearing out and the straps have lost their elasticity. I recommend this product.
