F2 HIGH-FLOW FILTER: 3/PACK
The F2 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.
FEATURES:
+ 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 exceeds that of homemade masks, bandanas, cloth masks, and paper masks
Common F2 uses:
High Intensity, Dust/pollen/cold air - No fumes/odors present.
Be sure you choose the filter size that matches your 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; grain bins, off-roading, construction/demolition, etc.
+ 50-60+ hours of continuous use when protecting against allergens, pollutants, odors, etc.

It's slightly more difficult to breathe, but this is to be expected and unless you do high-intensity training it won't be a big hindrance. Filtering capacity is remarkable. There is a tremendous difference in air quality with and without the mask.



I really like my RZ mask. great in a body shop, doesn't fog glasses, and even fits while using my welding helmet.

These are great filters for working in my wood-shop. I used to always get saw throats after working on major project even with other mask protection. I like the ability to keep my lungs and throat clear and still have ease of breathing with these filters for my mask.
