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've worn a number of respirators but this one is the most comfortable one that I've used. Usually they are hard on the bridge of my nose but this one is made for a longer wear time and is softer on the nose. I have found it to seal very well and since it's a 3M product, it has a large number of compatible filters. I have a beard and was surprised with the good seal that I still get. My previous 3M respirator was 25 years old and I didn't realize they recommend disposing of them after 3 or 4 years. I did and this one is much better than my old one. The valves work well and it is easy to breathe while wearing and I like that the out breath is pointed downward and doesn't interfere with goggles or moisture dripping on woodworking projects. I've been a bit concerned about wood dust since reading about all the allergies that it can cause and I already have enough of those so I decided it was time to find a good comfortable respirator to wear while woodworking.

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.

More better than the previous model.

Muy buena máscara con excelente comodidad y capacidad de ajuste, muy práctica. Recomiendo comprar las toallitas limpiadoras 3m para alargar su vida, y cuando sea hora de guardar que sea en una bolsa tipo ziploc.

works well no detectable odor in mask

Ha sido comprada por el tema del Coronavirus porque las demás mascarillas de cartas eran demasiados caras y sin sentido vaya. Esta es muy cómoda y protege muy muy bien, es praticamente eterna si se cuida y limpia. La ventaja de poder montar cualquier tipo de filtros no tiene igual....a mi ha sido genial.

All parts of the mask in contact with the face are silicone rubber(unlike the cheaper 6000 series) so feels very soft and comfortable. I have a large head do i was doubting whether medium will fit me, fortunately it fits perfectly.From area between eyes to the chin the mask measures around 13cm.across from cheek to cheek around 12cm.you can use this as reference while buying (medium size) I used it with 2091series p100 particulate filter.i used it to clean an old dusty room.wore continuously without any discomfort around 2hrs. You have to buy filter catridges separately.So best to buy this 7000 series instead of the 6000 series really worth the extra price.
