How should you choose the best RZ Mask for your needs? Not surprisingly, this is one of the most common questions we receive. Rest assured that, no matter which RZ Mask you choose, you’ll receive best-in-class performance, with 99.9% particulate filtration down to 0.1 micron in size – far exceeding the popular N95 standard. 


Lasting 10-60+ hours of use, depending on particulate levels, the F1 filter features best-in-class filtration plus active carbon to reduce odors and is standard in every RZ Mask.

The absorbent outer cotton layer stops larger particles while the tough polypropylene inner filtration media captures up to 99.9% of airborne particulates down to .1 micron.

The active carbon element removes pollutants in the air in including volatile organic compounds (VOCs), odors, and other gaseous pollutants from the air by trapping gas molecules in a bed of charcoal.


All RZ filters have been independently tested by an international microbiology lab, with results showing RZ filters exceed the NIOSH N95 filter efficiency standards.

We test both the filtration and breathability to ensure we’re creating a product that offers the best of both, so you can feel confident and comfortable while you work.

See Testing Details


Depending on the type of activity you’re doing and the dust level in your environment, RZ filters are good for anywhere from 10-60+ hours of use. When dust and dirt are visible on the inside of the filter or breathability has reduced, it’s time to change your filter.
