3M Half Facepiece Reusable Respirator Assembly Kit 6391, Size Medium, P100, Lightweight, Comfortable, Easy to Adjust, Includes 2091 Particulate Filter, Welding, Soldering, Asbestos

Straps can be a bit tricky to adjust and connect in back. Otherwise, comfortable and effective fit. Withstood exposure to high outdoor wildfire smoke level. Easy to breath through. Trusted brand. Replacement filters are easy to use and obtain. Highly recommended.

This mask seems to do the job. It's not the most comfortable thing to wear because it digs in around the top of the nose, but I am glad to have something to keep dust particles out of my lungs. It gets really sweaty after breathing in it for a bit. Overall, I would recommend it to others, just wish it was more comfortable. The straps keep it in place well, but the top one is also not comfortable for long periods of time.

This works to block out smells, does not feel hot inside, was cool, felt good, just wished it looked better to observers, I was so suprised that it was cheaper than a different mfg product I purchased but worked way better.

Good seal, light, and works.

this is the best for me , comfortable and keeps fumes from my face.thanks

This is a genuine 3M respirator appropriate for working around asbestos. It is vastly less comfortable than the many, many respirators I have used for other purposes. Having said that, the importance of having a top notch respirator in this instance cannot be underestimated.

I never know what I'm going to get with Amazon. Products advertise as a brand name and then you get something else. I received a real 3M mask product. High quality. Manufacturer filters. Purchase the medium size which fit well and is probably the best size for an average person.

The filters were supposed to be included but were not in the bag. The problem seems to be that the Bag 3M packs the filter/mask combo in has a ziploc top that isn't even sealed. It arrived open with the mask inside and no filters. That's ridiculous IMO. Don't know if they were "removed" at the warehouse or just fell out somewhere but caveat emptor. This would probably have been a five star review if it weren't for that issue, kind of hard to use a mask without the filters. Wound up having to buy filters separately.

I don't know why I keep seeing people hating on this because they didn't receive something.....Shipping errors happen, and I bet they took care of it once you complained!Anyhow....Shipment arrived, the one thing I would say is I would have preferred a bit more protection in the packaging. I did check all the seals and all, everything works fine, but looking at how it was packaged (just in a plastic bag) def left me a little concerned.Large fits me perfectly, and Medium fits my 10 year old daughter. I can't imagine how small a small is, but medium fits kids fine.All in all, happy with the product. happy with the shipping, unhappy with the packaging. 4 out of 5!

I am quite pleased with this mask. Im about 6foot 200lbs so bought a size large, and it fits me well. Much more comfortably than the medium. I called 3M's support and they confirmed this mask will fit any filters sold by 3M. I bought from Amazon, and the mask came shipped with a pair of 3M 2091 particle filters, perfect for the home renovations i am doing.

Inexpensive and reasonably comfortable. The build quality isn't amazing, but the main mask is soft and seals well. I think this is a great option for people who want a good respirator for the occasional project. It's almost infinitely better than those disposable things (about 150x better than a P95 mask) and still inexpensive. If you need this for daily use at work or something though, I'd recommend spending a bit more on a sturdier model.

Received the replacement mask the next day. Maybe Amazon employees should verify all parts are included. Other than that if fits great, glad i ordered a large

Package did not include respirator only filters. Amazing how someone lets that happen. The bag says 1 respirator and 2 filters but no respirator. Poot quality control. Now have had to send in request for actual product I paid for and hopefully wont get another empty package.Update: corrected in less than 24 hours great service package arrived as advertised and i will order more for sure. Great fix.
