i like the behind the head closer because i dont have to worry about my hearing aids when i take it off. but you must realize you still cant walk into a government building with one of these on due to the valves. and they wont accept the caps either. you make a good mask. ditch the valves they are not needed
The M1 mask has become my “go-to” favorite for a variety of reasons. It’s very comfortable (which I previously thought was an impossibility); it works extremely well in heavy sawdust and paint fume environments, and it’s value is unbelievable! I’ve told so many friends how much I love this mask! Thanks RZ for not giving up on safe, effective comfortable protection!
I still haven’t received these yet, after several attempts to ship to me.
I used their online fitting instructions to purchase a mask. I even went one size up in case of error. The straps were too short to close on the back of my head. There is no way to measure that. They did refund my money even though I tried it on. So good service, but could have been avoided if the strap length was known
The best and Comfortable
Value and comfort
Great product-comfortable to wear best materials utilized strongly recommend the M1 Neoprene Mask.
Filter great. Mask needs work.
These masks are great in theory. The neoprene hugs the face tight to create a good seal and the nosepiece crimp is way better than a standard N95. The filters do the job. The problem is the strap. If the back of everyones head was flat itd be perfect. Unfortunately it slides down without modification for me and all in my family. It needs a second strap across the top of the head to keep it up correctly. I am fortunate enough to have a sewing machine and neoprene to fix this and my design makes the masks wearable for my entire family, including my 8yo son. Normally for a child that age the mask would have to be a small, but a medium fit him. If you normally wear a large, order the XL, if you normally wear a medium, order a large. Overall I would still recommend this filter to others and in fact I have. But, unless you have a non-round head (lol) be prepared to modify for a "perfect" fit. One other note, most women and men with lady hair will have more of a problem with this mask in its current state due to slipping off of the hair.
We're sorry you had trouble with the M1 mask. To have a more custom fit, the M2.5 might work best for you with it's dual elastic strap system.
I use this mask while turning at the lathe and while sanding. It has been great so far for keep the dust out. And it is still easy to breath in.
I bought the mask primarily for woodworking. It definitely works great and my glasses don’t fog up. I wore it to a concert last week. 3 hours was a bit long with a mask, but it was comfortable.
I use this product in my pigeon loft and ot works great while giving me a maximum level of health support.
