3MReusable Respirator Half Facepiece 7501, NIOSH, 3M Cool Flow Valve, Dual Airline Supplied Air Compatible, Integrated Dropdown Suspension, Bayonet Connections, For Chemical Handling, Painting, Small

I did alot of research and read alot of reviews before purchasing this specific respirator. I was looking for something that I could wear for maybe 3-4 hours at a time while doing some woodworking and painting. It was important to me to have a good fit, one that was lightweight, comfortable, and hopefully easy to breathe in. My only experience with any kind of face masks prior to this one were the disposable kind that we have all been wearing for the past few years.I was SO impressed when I installed the filters and tried this on. Breathing was very easy - fresh air filled the mask when I would breathe in, and the mask did not feel stuffy or humid when breathing out. This was a night and day experience when compared to the disposable kind. I guess I had assumed that since this mask covers the entire nose and mouth (with a silicone seal), that breathing would feel uncomfortable and difficult - but I was so wrong. Additionally, I usually have some stubble / a short beard and this mask still formed a great seal. I would NOT recommend using this mask WITH facial hair in any environment with dangerous / hazardous materials, but for me - doing some light woodworking and painting, I had no issues whatsoever. I knew the mask was working when I would take it off, and I would be immediately hit by the smell/fumes of whatever I was working with, meanwhile when I had the mask on, I never smelled a thing! I also love that this face mask can be washed with soap and water, because I definitely want to be able to was this periodically if I'm going to be spending so much time breathing through it.As for sizing, I went back and forth between trying to figure out if the medium or large would be better for me (adult male, 30s, 5'8", size M clothes generally). I think I read in some materials from 3M that approx. 90% of adults would wear a size M in this mask, so I decided to just risk and go ahead with the Medium - it turned out to be perfect. I don't know how large a L actually is, but the fit of this mask from the bridge of my nose to under my chin fits like it was molded for me. Very happy with how the sizing turned out.Lastly, and most importantly, make sure you buy the correct bayonet filters for whatever application you are using this for. That seems basic, but I'm sure that lots of people don't realize that some filters are just for dust (not gases), and then the filters for gases have different degrees based on the environment you'll be working in / the chemicals you're working with. This mask won't be any good to you if you don't buy a filter that protects you from the substance you're working with. I hope this helps you!

This is one of those things where once you work it into your routine you kick yourself for not doing it sooner. Swappable specialty filters are perfect for woodworking with dust or vapor safety, airborne particulates from sanding, planing, jointing etc., can be downright dangerous for your lungs, some woods are even toxic, and the vapors from finishes can be just as bad. Protect your health from inhaling airborne pathogens when cleaning up mouse traps, using sprays cleaning your bathroom, I also use this for dusty yardwork now, gone are the days of blowing dirty snot out my nose...the list goes on and on, this is a must have item. The silicone on this is very comfy for long term use, swapping filters is a breeze, cleans up super easy end of day just removing the filters and running it under the faucet.

I use this respirator with 2091 particulate filters for woodworking, yard work, leaf cleanup. The respirator does NOT come with any filters so be sure to order them with the mask if you don't already have them on hand.The mask fits well, the large was a good size me because I'm a big guy at 6'1" and 205 pounds with a round face. Its comfortable in temps to 80 degrees, after that, it gets warm. But it's fall in the Northeast and its leaf season which makes for dusty, dirty work and this mask keeps leaf dust, mold and pollen out of my respiratory tract.The material is soft, comfortable, conforms to my face and seals well and the 2091 filters are great for fine dust.I wish the neck strap was about 2 inches longer, it's a bit tight for me fully expanded. Otherwise, this respirator is ideal for my purposes.

I’ve had a 6300 series mask for a lo me time, and it was time for a replacement. This fits better over the nose, seals easier, and is an overall improvement. The only thing I’d change is to make the neck strap a little longer (yes, it’s adjusted all the way out). It’s barely long enough to not put too much pressure on my neck/lower face. To be fair this happened with my old mask as well.
