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.

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.

Filters are fine. The masks could use improvements. I started with standard, but with only 1 strap it didnt hold comfortably, pulled downward which caused it to be loose on bottom and not a good seal, but the velcro was good. 2.5 mask with 2 straps is ver difficult to unclip with tiny clips and the fact that both straps go to nearly the same place where they attach makes 2 straps not as good as it could be if they were placed further forward on the mask giving them more distance between the 2. Also why cant the 2 strap version be made with velcro? Or at least a larger clip, one like you would see on a 3m respirator.

Great service- quick delivery to Ontario. Thanks again. Great product.


Comfortable and affordable dust protection. Easy to breathe with

I find these to be very comfortable and highly recommend them. My university bought these for our faculty for use in F2F classes. Highly recommended


I like the high flow of these filters. I did complain about the foam nose piece coming unglued on an earlier purchase of these. RZ sent me these for free.
