F2 HIGH-FLOW FILTER - 12-PACK -MEDIUM (M)

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 sealSurpasses 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, UTPerformance far and exceeds that of homemade masks, bandanas, cloth masks, and paper masksThe 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.
