The F1 is the standard RZ Mask® filter, consisting of two layers. The first layer is a highly effective particulate filter, trapping particles down to .1 of a micron in size. The second layer is an Active Carbon Element, which helps to reduce harmful fumes and odors. The best part? All RZ® filters have been laboratory tested to be up to 99.9% effective!

FILTERS ARE AVAILABLE IN EITHER 3 PER PACK OR 12 PER PACK

Features:

• Best-in-class filtration with 360-degree seal
• Active Carbon Element reduces odors
• 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 exceeds that of homemade masks, bandanas, cloth masks, and paper masks

Common F1 uses: Low intensity wood dust/fumes/odors/smoke/pollen.

Be sure you choose the filter size that matches your RZ mask size:

• Medium Filter = Medium Mask
• Large Filter = Large Mask
• X-Large Filter = X-Large Mask

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; woodworking, carving etc
• 50-60+ hours of continuous use when protecting against allergens, pollutants, odors, etc.
