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.

Great masks, great replacement
These are exactly what we need in the mask everywhere environment.
F1 Mask Filters
These filters are great. Nice that they can be changed easily.
You can’t beat the RZ masks for fit and comfort. The filter refills are very affordable too. A great product that I continue to recommend to friends.
I wear my mask all day at my job. Overall, I really like it. However, I have had to make a modification to the filter. The foam nose piece rolls off and sticks to my skin. To fix this, I re-glue the foam to the mask with Gorilla Glue. This allows me to wear the mask more comfortably. I am also wondering if a smaller size would fit me better.
