F2 HIGH-FLOW FILTER: 12/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 was better than expected. After wasting money on other masks, I finally purchased a good mask that filters down to .5 microns. I use this in my shop and notice that I have 0 dust infiltration. My sinus and allergies do not bother me with these Masks. Also I like the fact that my glasses do not fog up and am able to clearly see pencil lines and is much safer on power equipment.

Refill and mask work great. My son is a welder and uses all the time.

I purchased an RZ mask with the F2 filters. I am a high school teacher with asthma, so I am extra careful to take every precaution with Covid. I have been wearing the RZ mask all day for about 7 hours straight in school, and it works great. I can breath very easily with it and I highly recommend it!


I use the mask for woodworking. I am satisfied with the way they filter out the dust.
