F3 High-Flow + Active Carbon Filter: 3/Pack

The F3 is our premium RZ® filter, and combines the best technologies from our F1 and F2 filters. The first layer is a High-Flow Electrostatic Filter, trapping particulate down to .1 micron in size (with 40% better breathability than our standard F1 filter). 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!

+ Best-in-class filtration with 360-degree seal
+ Active Carbon Element reduces odors
+ Filters 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 uses: 
High intensity, Dust/pollen/smoke/fumes/odors. 


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.

RZ Mask and Filters

Excellent product. The RZ Filters along with their signature Masks, either Neoprene or Mesh, RZ expertly designs and engineers enabling easy use by the craftsman. The RZ Masks are the best fitting Masks I have found. RZ Masks and Filters are my choice for all projects that I have.

Love my new mask!

This is by far the most comfortable mask I have ever worn. Its lighter & cooler than all of the other masks I've used, and I can wear it for a long time and barely notice I have it on. Highly recommend!

Mask filters

I am so glad I discovered these masks and like the new filters I ordered. I have asthma so this really helps keep the dust out of my lungs. I love woodworking and using all my saws. So this allows me to continue doing what I love.
