The F2 is our is our High-Flow filter, with 40% better breathability than our standard F1 filter. It uses a highly effective Electrostatic Filter, which traps particulates down to .1 micron in size. The best part? All RZ?« filters have been laboratory tested to be up to 99.9% effective! Note that this filter does not contain an active carbon element, eliminating the filtration of fumes and odors.

• Best-in-class filtration with 360-degree seal
• Surpasses the N95 standard, filtering up to 99.9% of particulates down to .1 micron in size (400 times smaller than a human hair)!
• Independently tested at Nelson Laboratories in Salt Lake City, UT
• Performance far and exceeds that of homemade masks, bandanas, cloth masks, and paper masks

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 ?Çô 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
