RZ Mask Air Filtration Dust and Pollution Mask M2 Mesh - Large - Black - BONUS Includes 5 F1 99.9% Filters (Large)

Both plastic vents on the mask fell out when I was blowing cellulose insulation into my attic. I bought this mask specifically for this job and was very disappointed with how easy the mask fell apart. I couldn't find the plastic pieces as blowing cellulose is a dusty job. This causes the filters to slide around in the mask and the little vents stopped working properly. I had to stop my work and go to the local store and buy a different mask. Frustrating to say the least.

I was really hoping for a little more satisfaction with this item after seeing it on a few woodworker's YouTube sites, but it just seems to not be quite what I need. Maybe I should get the XL size because the L just isn't terribly comfortable, but after using it I can't return it to exchange it and I'm not going to spend another $30+ for another size. Seems to filter out dust pretty well though, so at least it's functionally good. Just not a great fit, so I'm bummed.

Much better than the cheap disposable ones. The filters it comes with are very good for sawdust, and even seem to help some with fumes. Fogging is less of a problem than with the cheap masks, but I do get some if wearing both my glasses and goggles. The sizing is a little small, so get the next size up from what you normally would. Overall, I think it's a good product at a reasonable price.

Was looking forward to this product, but unfortunately had to return it. Gave me a headache from pressure on the bridge of my nose and fogged up my glasses instantly. Ordered the size per their instructions, but it just didn't work for me.

Helps prevent congestion after spending a lot of time in the shop and making a lot of cuts. Much more comfortable than most others.I got the medium but I wish I'd have gotten the large.

It worked okay. Better than nothing in the smoke of a California wildfire gone nuts, but put a lot of pressure on the bridge of my nose even if the metal clasp wasn't pinched at all, and let a lot of non-filtered air in from below my chin. I should have gotten a size larger, but they were unavailable. Also tried it for sawdust while woodworking, and ended up just buying a 3M mask with a charcoal filter instead.

Very good mask. one of the best I have had, but it doesn't quite fit as comfortably as others say.It's a little pinchy on the nose and just doesn't fit me right. But I still use it, and it works well.

Easily the best dust mask I have used. It is comfortable and stays in place. Also it will fit under a face shield.
