Question: Will breathing out while wearing this mask fog up your glasses like some of the other (cheaper) masks do?
Document: This mask truly is horrible in my opinion. We purchased two of them during different times of the year, and both started deteriorating. Instead of being cleanable, these start to chunk off like a really lousy pencil eraser. It's a gummy type of rubber not meant to last. We've only used them for dust, no fumes/solvents. Since the blue rubber doesn't stay intact, seals become nonexistent around the face where it counts.The other huge CON about this mask is that it causes pain when wearing glasses.
This respirator fits very well. It slips on over my safety glasses and it fits under my face shield I use for woodturning. I've only used it a couple of times but I can already tell it works very well on fine sawdust particles. I've tried so many different types of dust masks and they all fog up my glasses and face shield. This respirator fits over the tip of the nose and allows room for a pair of glasses behind it.
Mine is failing the negative pressure test every time no matter how I adjust it. Maybe my face is too small for the mask? *Update three days later: I'm not sure why, but I guess I just needed to get used to the feeling of the respirator, because I no longer feel like I'm going to pass out while wearing it unless I work too hard and start to get out of breath-- then I need to get outside and take the mask off. Otherwise, it's been okay.
I make wire for a living, and when we melt down the plastics to put the jacket on different wires, so of it burns. It's an unavoidable aspect of wire manufacturing, and the unfortunate side-effect is that carbon is released into the air. Eventually, that carbon has to come back down, looks like gray and black dust. So when I have to clean, I put this on. I have stopped having breathing trouble after cleaning since I started to use this.
Great mask for certain jobs, But I should have purchased one with a full shield because I wear glasses and goggles don't fit well over them! just do your home  work first before  you choose the right one! Still a great product and fast shipping!
Not as good as the 3m, but darn near. Very durable and strong. Good quality air filtration and very little breathing resistance. Great for anyone with allergies, or sensitivity to chemicals. Highly recommended. The mask was i little too small for me, but that is my fault not MSA's. All around a great product and a great value, Especially if you have a job that requires p100 protection.
So you have to slide both top and bottom straps over your face and head to put on and take off, where as something like 3M, you can drop it down from the back over your face, then clasp the bottom strap behind your neck after the mask is on your face.I do like that the mask has a small profile and the filters are small in size.But if you don't have to use this very often (like once a month), it's a good deal.
I have been wearing respirators for 15 years. I've tried countless different styles, designs, and brands. I have to say that this mask is the most comfortable. The blue gel part that rests on my face is comfortable and durable. My working environment is extremely warm and humid and I sweat a lot. This mask provides the best breathability, comfort, and humidity release.
I use this mask when I'm doing hardcore sanding and painting...it's great. Unlike the crappy paper masks this one actually allows you to BREATHE easy while working. The filters claim to stop everything...I'm still alive after staining a ton of stuff and sanding plywood furniture. Good product.
I wore masks from Menards, Home Depot and those usually fell apart after a month. This mask is a lot smaller, more comfortable , is lasting me 8 months and still good. This only problem is the neck strap, it doesn't have a clip for easy dismount. I bought some plastic strap buckles, cut neck rubber strap in half, glued it in and it is a perfect mask now.
