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. 


For all day wear or active projects like building, landscaping, or demolition, upgrade your filter to the most breathable RZ filter with odor reducing active carbon.

The F3 filter adds a 5th layer of technology featuring electrostatic filter microfiber media that is designed to be highly breathable and protective, capturing up to 99% of particulates through static electricity.

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.
