The F1 is the standard RZ Mask filter, consisting of two layers. The first layer is a 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. All RZ filters have been laboratory tested to be up to 99.9% effective!

Sent wrong size
We got our mask from Amazon and needed new filters so we ordered what was in the mask and they were to big. I bought 3 boxes of 3 to a box. I’m scared to reorder because that’s the only mask we have and trust.
