RZ Mask

This intelligently designed dust mask is more comfortable, stylish, and reusable than the ones you’ve seen. RZ Masks have a two-part design. The replaceable filter part is really great at cleaning out even the tiniest particles (ones as small as 0.1 micron, or a millionth of a meter). The mask’s reusable, face-contouring, moisture-wicking mesh part helps increase airflow and means you don’t have to toss the whole thing when you’re done. You’ll breathe in clean air, while particles of pollen, bacteria, wood smoke, dust, auto emissions, and other pollutants stay out. With a background in dirt biking and construction, Maker Steve Torbenson understands the perils of dust all too well. He wanted to design a mask that was comfortable and attractive for bike commuters to wear under helmets or construction workers to use during the day. RZ Masks are flexible enough to conform to your face but also to fit in your pocket. And they’re practical enough to keep using half the mask over and over again.
