3M Half Facepiece Reusable Respirator 6300, NIOSH, Large | Four-Point Harness, Comfortable Fit, Dual Airline Supplied Air Compatible, Bayonet Connections, Painting, Sanding

I chose this face mask based on the reviews and price, and I am very satisfied. I'm surprised this is listed as a Large size. It fits me fine, but the adjustment straps are near their ends so if I had any fatter a head I'd be in trouble. I'm a lady. So for any jumbo husky man, he might have difficulty with fit (specifically with the straps to hook behind your neck). I like the placement of the straps. They do not interfere with my large ponytail/bun and do not get tangled in hair. It is easy to put on and remove. I sometimes have the issue of one of the filters falling off, but that's just because I didn't check to make sure it was screwed on properly. You don't want to screw on so much that it screws to the open position, but just enough to hold the filters on. I bought the 3M P100 filters through amazon for this and they work great. I never used one of these facepiece respirators before, but now that I have I no longer dread dealing with all the smelly and previously allergy-inducing chores I must do. Previously I was just using a disposable hospital mask for any troublesome tasks, but of course there's no comparison since this facepiece respirator actually does the job of filtering and whatnot. It's easy to breathe. I've only used it so far in this hot weather, so I get a bit sweaty if using it for extended periods of time. I also find myself "mouth breathing" with it on, but that's fine. Guess it goes back to my snorkeling days. And I suppose me doing the mouth breathing thing helps when I've used this for dealing with smelly garbage or cleaning out the goat shed. It seems to really be effective in moldy environments, especially when used with goggles (and there's no interference with space/comfort/etc. while wearing goggles and this facemask). No more headaches or itchy eyes or runny nose or any number of allergic reactions I usually would have when dealing with these environments. The price is excellent compared to in stores. Lots of opportunities to use this respirator. Changing a baby diaper? Dusting the mantle? Sawing a 2x4? Raking leaves? Making soap? Going to Kmart? Going line dancing in a barn? So many opportunities to breathe cleaner air.

Wonderful mask, fits great, works great. And I can now change out my filters, there are two (2) types used on this mask. Do your lungs a favor, buy this mask today. Worth every penny.

Paired with 3M P100 filters and works perfectly while I'm grinding metal and welding. Originally order a Medium but was sent a Large (luckily enough as I am not sure the medium would have fit).

This respirator works great for woodworking and painting. It provides solid protection and feels very well-made. The fit is comfortable, and the four-point harness makes it easy to adjust so it stays secure without feeling tight. I’ve been able to wear it for extended periods without any discomfort, which is a big plus.The only reason it doesn’t get five stars is that it doesn’t come with any filters, so you have to purchase those separately. Aside from that, it’s a great, reliable respirator that I would definitely recommend.

I use this mask while cutting 5 acres of grass. I bounce around a lot and I can say the seal is very good. As far as comfort I don’t get any marks from the mask after hours of wearing it. There is plenty of room within it does not feel cluster phobic at all. The over all quality is really nice and seems very durable. I water 6 months to leave this review. I would purchase again.

Esta máscara es justo lo que estaba buscando he visto otras marcas pero los accesorios no coinciden con lo que se en cuentas en el mercado y 3 m tiene una amplia gama de filtros compatibles

Definitely worth having in this day and age

The soft silicone faceseal molds easily to my face (even with facial hair) producing a snug but not uncomfortable fit especially over long periods of time. Of course the useability depends on the filters but with the recommended rated 3M filters, solvent-heavy paint jobs and dusty renovations have no odor seep-through and are relatively easy to breath. It does have a "Cool Flow™ exhalation valve" but i wonder if this doesnt just defeat the purpose of a filtering respirator? I haven't experienced any issues, but still seems silly to have an actuating valve front and center that opens and closes without filtration. BUT without it, I know how absolutely unbearable and miserable it is wearing one of these on a scorching hot day so I really can't complain. And it's a silicone seal with two large very secure straps, it does not come loose when you sweat up a storm, but it will feel uncomfortable.

It's ok. I mean the smell of latex is bad but it does the job given that u have proper filters attached to it. I used it against fumes of welding and stuff. It works.

My mask arrived all sticky and greasy. It seems to be authentic but just so dirty I had to clean it many times. Either it’s used or someone tampered with the product in a bad way.

Material received but not completed and filter missing and mask is already used and stinky
