M1 Neoprene Mask: 1-Strap System
The M1 Neoprene is the original RZ product. Like all RZ Masks, it features our standard F1 filters, blocking 99.9% of particulates down to .1 micron in size!

The M1 Neoprene Mask is made from the same material that’s used for wetsuits – making it comfortable, durable, and perfect for adding comfort in cooler temperatures. It features a single strap hook-and-loop closure, aiding in quick installation and removal of the mask.

M1 Neoprene Mask Features:

  • Durable neoprene construction helps keep you comfortable in cooler temperatures
  • Adjustable nose clip eliminates any fogging of your glasses
  • Dual one-way discharge valves reduce moisture inside your mask
  • Best-in-class filtration and comfort with 360-degree seal

valve reject

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

Excellent product

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!

fitting guide

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

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.


RZ Mask

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.

Great Mask

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.

Great Mask

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.
