According to latex particle challenge tests performed by the world renowned, Nelson Laboratories in Salt Lake City, RZ Mask's F1 and F3 Filters, filter 99.9% of all particulates to a size of .1 um.

F1 Standard + Active Carbon Filter:
Made with 2 layers of particulate filters
Outer layer filters particulates down to .1 micron in size
Inner Active Carbon layer effective towards fumes and odors
Laboratory tested to be 99.9% effective
Common uses: Low intensity, dust/fumes/odors/smoke/pollen

F3 High Airflow + Active Carbon Filter:
Made with 2 layers of particulate filters
Outer layer filters particulates down to .1 micron in size
Inner Active Carbon layer effective towards fumes and odors
Laboratory tested to be 99.9% effective
Promotes 40% better breathability than our standard F1 filter
The RZ F3 Filter is above general inhalation standards
Common uses: High intensity, Dust/pollen/smoke/fumes/odors
