3M Reusable Respirator Half Facepiece 7502, NIOSH, 3M Cool Flow Valve, Dual Airline Supplied Air Compatible, Integrated Dropdown Suspension, Bayonet Connections, For Chemical Handling, Painting, Med

I purchased the 3M P100 professional filters (3M CARTRIDGE FILTER ORGANIC VAPOR/ACID P100) and 3M P100 Particulate Filters (3M Particulate Filter 7093B, P100 Respiratory Protection (Pack of 4)) from Amazon.com to use with this respirator. So far, I've used this mask for the following:--yardwork (mowing/trimming/leaf blowing 1/2 acre lot)--sanding some drywall in our basement (with limited access to ventilation)--cabinet sanding/priming/painting (ditto on the ventilation issue)--outdoor allergen barrier in the late spring.So far, it's performed really well for all tasks.Pros:--All straps are adjustable, so it should fit most heads pretty well. The straps that fit around the upper cranium are flat enough that I can still wear my sunshade hat over it. The strap that goes around the back of the neck/lower part of the head is pretty standard and necessary if you don't want air leaking in around the chin.--The mask is air-tight around my cheeks and nose. I've had issues with other respirators because my cheeks are kind of hollow and it is hard to find a respirator that conforms to the shape of my face without leaving deep dents over my nose and cheekbones. This respirator has a rubber gasket-like material that helps with the seal against the face and keeps the mask from leaving crazy dents all over your cheeks and nose after you remove it. There were a few marks, but nothing like the plastic-surgery-gone-wrong/Frankenstein's-monster issues that some of my other respirators have had.--Ditto Rachel Levine's earlier review regarding vents: the downward venting design does a good job of preventing fogging of glasses and goggles.Cons:--The rubbery gasket next to your face on the mask causes it to slip a tiny bit when you sweat. I wore it while priming in the 80 degree garage for about 1 hour and had to keep adjusting it because it wanted to slide down a few millimeters from all the sweat. I didn't have this problem when I was working outside in 65 degree weather (not sweating).--The mask is a little heavy for a 5'4" 130lb female, but not uncomfortable. For people with stronger neck/face muscles, this wouldn't even be a consideration.Solid 5 star recommendation for this product.

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!

It's a 3M respirator, it doesn't get much better.Sure there are other makes out there, but these are cheap enough and very comfortable. I'm always restoring one classic or another, constantly around dust or spraying automotive paint in an enclosed garage. This one is so comfy, I just leave it on all day. No more mud filled snot to blow out at the end of the day!The pink dust filters work great. The canister 3M filters specially for automotive paint, work fantastically! If you've ever sprayed cerakote, you know just how bad it is, fume wise. The 3M filters remove 99.9% of the fumes. It's hard to even tell there are fumes.3M respirators are the only ones I use. Sure I could save a couple bucks on an off brand, but you only get one set of lungs... How valuable are a couple bucks really in the end... Not worth it, 3M for me and my kids that come to help me in the garage. If taken care of, these should last a very long time. I wouldn't put them in a sealed bag after use though.... Bacteria from your breath will breed like crazy in a sealed environment. Better to leave it out and either blow it out or wipe it out before the next use. I use alcohol wipes, works great.OH, and this seals around the biggest beard (Mines very thick and large). Glasses are basically useless unfortunately. The top head strap is thin enough to be worn under a hat without issue. Ear muffs are fine with this too. As for welding helmets, I've got a Hobart and a YesWelder helmet, although a tight fit, the mask with paint canisters fit behind the helmet.
