These are replacement filters used in RZ Mask Reusable Face Masks.

RZ Mask has taken two extraordinary air filtration filters, the F1 and F2, and created the RZ Mask F3 High-Flow Activated Carbon Replacement Filters used in RZ Mask Reusable Masks. By combining both the F1 and the F2 into the F3, you get the fume and odor-reducing power of the activated carbon filter (the main component of the F1 filter) and the impressive breathability feature, which makes the F2 filter so attractive to consumers. Just like its counterparts, the F3 lasts 20 to 30 hours in heavy dust exposure, 30 to 40 hours in light dust exposure and 50 to 60 hours when exposed to other types of pollutants (allergens, dust, odors), and is available in medium, large and extra-large. The F3 is a must-have air filter for RZ Mask owners that want incredible air filtration and exceptional breathability.
