"This mask provides an excellent and comfortable fit, easily conforming to my "unusual shaped" face. I was using this for >1 hour whilst drilling masonry, without any discomfort. I regularly use 3M respiratory protection products at work and this one certainly delivered for my DIY project- the 3M brand is very dependable. Highly recommended."
"Bought this whilst doing a lot of sanding to provide a key on previously painted surfaces indoors. Was a lot more comfortable than the cheaper models, and hopefully did a better job at filtering out dust particles."
"Needed to do a fair amount of sanding and sorting dusty areas and bought this to save my nose.... For the money it works well and with the valve is comfortable to ware. Used several times now and still going strong. Not as good as a full face job but I find I use it more often as more confortable and you do not look like darth vadar!!!"
"These dust masks are very effective. They not only do the job of keeping harmful dust from being breathed in, but they are comfortable to wear, making an effective seal around the nose thus preventing the glasses from steaming up!"
"Really comfortable to wear and easy to breathe. A good seal on the face and does not mist up safety specs if worn. 3M are streets ahead of the competition. Cheaper if you buy a box though rather than individually."
"These do a good job at protecting your lungs. Easy to fit and not too uncomfortable. I'd think of them as disposable as mine got drenched in sweat after a couple of hrs hard work up in confined space of a loft.
Very good though. Shame they aren't available in a multi-pack, so they could be cheaper."
"Bought this as I was demolishing a wall in my kitchen and also to use when doing some sanding. Performed well and didn't steam up my goggles! Although I got a few uses out of it I have since snapped one of the elastic straps so now need a new one - so don't stretch the straps too far!"
"I have always had a problem with the cheap disposable masks either cutting into my face or not sealing properly and steaming up my glasses. These are much better for all three of those problems. They seem more robust and i feel more confident that they are actually stopping the dust from getting into my system."
It does what it says on the tin really, keeps the dust out and does that pretty well. I did notice that I had a clearer nose after using this mask for a few days, and as I wear glasses I also appreciated the metal strip aroung the top of the mask to mould it to my nose, stops the glasses fogging up!
It's also not too restrictive when breathing, also useful when working hard although you do find that after wearing it for a while though the valve starts to collect moisture and can drip, but that's minor issue.
To sum it up, better working with one than without, it is effective, but for something that is semi-disposable it is a bit more than you'd expect."
