The F1 is our standard RZ Mask® filter, consisting of two layers. The first layer is our highly effective particulate filter, trapping particles down to .1 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!

+ 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 F1 uses: 
Low intensity, dust/fumes/odors/smoke/pollen.


Be sure you choose the filter size that matches your mask size: 
Medium Filter = Medium Mask
Large Filter = 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.

Background for this - I bought this because I live in CO and the smoke from all the wildfires in California gets funneled here. So - bought the mask plus some extra filters for it around $70 or so. • The clips that hold the mask on are tiny, so its difficult to get them open - and I'm a petite woman with tiny hands. • One of the straps already has some shredding/fraying elastic from adjusting the length. • I thought the filter would be sandwiched between a couple layers of fabric and fastened with the valves - its not. Its right against your face. The up sides - • decently easy to switch filters. • mask stays in place nicely • its comfortable to wear and doesn't build up too much condensation or leave marks on your face • no foggy glasses Do I think its worth the price being charged for it? No. Hands down no. If you know a seamstress you could make a mask to hold one of these filters on pretty easily - especially as they sell the parts like the valves separately. If you're handy with a needle and thread - skip buying the mask, get the filters and the valves. Make your own. Save you about $40+

I know that they are supposed to protect and what not. But holy cow the chemical smell they have is nauseating!
