HOW LONG DOES AN RZ FILTER LAST?
The life expectancy of the RZ Filter depends on many variables, such as; particulate exposure density, particulate exposure duration, and user breathing rate. With that said, below are our general guidelines – as the user will have the final call given your exposure.
+ 20-30+ hours of continuous use in heavy dust exposure to things such as; grain bins, off-roading, construction/demolition, etc.
+ 30-40+ hours of continuous use in light dust exposure to things such as; grain bins, off-roading, construction/demolition, etc.
+ 50-60+ hours of continuous use when protecting against allergens, pollutants, odors, etc.
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.
