Your cart is empty.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!

Everything seems fine and the filters shipped quickly. Overall this was a good purchase.The mask these go with is much more comfortable than the fully disposable masks and also seems less wasteful since less is disposed of when the filter needs replaced. The filters themselves seem to do the equivalent of the fully disposable masks so I don’t think there is a difference in protection.Plus when compared to the vented disposable masks this option is much cheaper and prevents fogging just as well or maybe even better.

I've been using these filters since the great pandemic of 2019-2020. I still use them today for various projects.
