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.

Excellent product. The RZ Filters along with their signature Masks, either Neoprene or Mesh, RZ expertly designs and engineers enabling easy use by the craftsman. The RZ Masks are the best fitting Masks I have found. RZ Masks and Filters are my choice for all projects that I have.
This is by far the most comfortable mask I have ever worn. Its lighter & cooler than all of the other masks I've used, and I can wear it for a long time and barely notice I have it on. Highly recommend!
Easy to switch out. Seem to work great
Woodworker dust from sanding.
I am so glad I discovered these masks and like the new filters I ordered. I have asthma so this really helps keep the dust out of my lungs. I love woodworking and using all my saws. So this allows me to continue doing what I love.
