been using this for woodworking and other dusty jobs. I also use this for my industrial job when it gets dusty. It's important to get the right fit for these, so research how to get the right fit before you purchase, a bad fit will make this great product ineffective.

Much more comfortable than "ordinary" masks.  The air vents are a great help, and the moldex webbing prevents the filter medium of the mask from finger/hand dirt.  I have another 10 pak on order, but this time with the charcoal filtration.......for our woodshop.

In terms of fit, dust leakage around the side of the mask, and durability this is a better quality filter mask than the ones I have used in the past.

The construction of this mask is a bit different from others of this general type.  Most masks of this type have little depth. This mask is thick and has two part construction in depth.  The surface of the mask is rigid on the outside. The interior of the mask is softly compliant. The springy exterior of the mask keeps the straps from pulling out, keeps the valve where it needs to be and holds the mask shape.  The interior of the mask is soft, follows the curves of your face and wicks away sweat. The compliant, soft surface of the interior is perhaps the most important feature of the design both in terms of the fit and in preventing from dust from working its way around the side of the mask into your nose and mouth.

The breather valve has been added to reduce the effort in breathing through the mask.  This is not the only function the valve has.  The valve is positioned to guide your breath away from your glasses.  This means that on cooler mornings that my glasses do not fog up.  If you do work which routinely requires masks you will recognize this problem.  Heat rises. With a mask without a valve my warm breath rises from the mask and fogs my glasses. The valve exhaust is positioned to prevent that.  On all sorts of levels this mask has been carefully thought through both in design and construction.

By the way I have no relationship with 3M or any of its distributors. No one paid me to write this product evaluation. I appreciate the reviews written by others which guide me to better tools and more durable products, and help me separate good tools from cleverly packaged junk. I am returning the favor.

I use this mask for wood working.  It does better than paper masks with filters.  Didn't realize my face was big... Should have ordered the next larger size.  Hard to tell about sizing until you try it on.  Happy with purchase and would recommend to others.  Comfortable.

Comfortable to wear, and effective on keeping your face warm. Although fabric material is a on the lighter/thin side, could use a thicker fabric.
Over-all it served it's purpose, shielded my face and kept me from having windburn.

Tight seal around the face makes for effective dust control.  I've had this mask for several years and wear it regularly to cut grass since I became more allergic and find that it is reasonably comfortable even in hot weather.

I had been using disposable dust masks up until this point. This is a HUGE improvement over those. I have some facial hair, so the fact that it seals over my face is a huge plus. Additionally, it is incredibly easy to put on this mask and take it off. I can easily grab it as I walk out to my garage and put it on while walking with no thought. I really like that it has the vent out the front that blows down, so hot air is directed away from your safety glasses. The silicon makes this mask quite comfortable to wear. However, I did find that even with the vent downwards and the good seal, it manages to fog up my glasses frequently after a short time of wearing it. When I'm wearing earmuffs as well, this makes it a bit annoying to have to step back from a machine to take off the earmuffs, take off the glasses, wipe them, them put everything back on. Overall a very good product though.

Bought these to wear while removing drywall. They are easy to adjust to your face and fit closely. The masks are comfortable to wear. One odd thing is that my nose seems to run constantly while wearing them.

I'm really glad I bought this set because the mask is noticeably bigger than the Cressi mask I bought for my wife with a different snorkel / fins combo. This mask has a larger form factor / frame, and the single lens that extendes all the way across seems nice. I have an above average sized face / head (Male, 5' 11", ~180lbs)  and am happy with the size / fit of this mask. It does not leak, although I really need to clean it well and apply some anti-fog solution because it was fogging up. Pretty common in my experience with any mask.  This mask is labeled Made in Italy.

The snorkel was fine, although it appears to be directional, meaning the angle of the mouthpiece into the tube is not the symmetrical, and the angle seems best when the snorkel is clipped to the left side of your head/mask. The floating valve on top works well and I can always swim well underwater and get no water entry when I re-surface. If you blow out hard there is a soft rubber cover at the bottom of the snorkel that will flap open and blow out any water, and it has yet to let any water in. It seems soft and flimsy, but does its job. This snorkel was labeled Made in Taiwan. Boo.

Very happy with this mask. Even the stock filters do a great job with aromatics like adhesives, paint, etc. Recommended.

I received my sleeping mask in grey color.  Mask arrived in a beautiful professional packaging box.  It can be used for relaxing.  I like to use it for meditation.  I like to plugin earphones and use muse for meditation.  Convenient thing about this mask is that it can be easily washed so it is clean at all times.  Size of the mask is generous so no light can get in.  Your eyes will be rested.

Great mask.  Made painting enjoyable instead of a headache.  I have chemical sensitivity, and this allowed me to paint without a problem.  Easy to breathe through, doesn't get too hot, and fits well.

My wife is thrilled that her new mask is so comfortable.  She uses it for up to an hour at a time in a lap pool and has no discomfort or facial marks when she is finished.  It has been used 5 days a week for two months and has not stretched at all, the strap adjustment is on the same notch as the day she got it.
She highly recommends this mask.

This is quality mask. It's thicker than the cloth masks I'm used to so it holds it's shape on your face. The valve makes all the difference! It's easy to breath through and my face stays cool. This little mask will save my lungs in the grooming salon.

Have been using this for shaping surfboards, outstandingly dusty work, and it works great for that. I don't think anything gets through. It's very comfortable and that head-strap is great, very secure. It's a little warm, but I think that's the case with any mask. I think it's very breathable, more so than other cheaper masks I've tried. It does block a lot of your voice since its so thick which is why it earns a 5 star review from my wife. You just have to talk a little louder. Works fine with glasses/goggles. One final note - this did not come with the pink filters that are shown in the pictures. You have to order the "3M P100 Particulate Filter with Organic Vapor Relief, 2-Pack" separately, and 2-pack means 1 pair.

This is comfortable, very clear mask.  It fits both my 12-year old son and my wife, and is made of very soft plastic.  My 12-year old echoes those comments in that it fit very comfortably with no points where it causes irritation, and that it is very clear.  It also comes with a free mesh bag to hold the mask and other small gear, which is a nice touch.

As someone who is plagued by allergies to dust and pollen, I learned long ago never to clean house or sweep outside without wearing a dust mask.  I had purchased a couple of of the hard shell type N95 respirator masks for some major clean up projects and could tell such a positive difference with the N95 filtration, that I decided to use the N95 masks for my everyday cleaning as well.

Why do I recommend this product?  This mask is SO much more comfortable to wear!  It feels more like a fabric and adjusts better to fit a woman's face. There are no hard edges digging into my skin and there's no fogging of my glasses.  I especially like the flexible bottom flap that folds down to go under your chin.  Because of the way it's sewn, I've found I can push it up temporarily just enough to stop for a drink of water without letting all the dust in or shifting the placement of the mask on my head.  As a result of these pluses, I can easily tolerate wearing this mask for a much longer period of time.

When I remove the mask, there aren't any leftover telltale indention lines on my face like those caused by a hard shell type.  I've not experienced any issues to date with the elastic bands breaking, and I'm stretching them (carefully) around a head of very thick hair.  I actually like that the bands are flat, smooth, and once in place, they stay put without digging into your skin or sliding around on your hair.

These respirator masks store flat when new, and once used, store flat with the exception of where you've adjusted the noseclip.  (And you could even reshape the noseclip flat if you wanted.)  I give this product 5 stars for effectiveness, comfortable extended wear, and convenient storage.
