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
