Great Product

I bought this mask and replacement filters maybe 2 years ago, and it's the only comfortable dust mask setup I've ever used. I confidently use it at my jewelry bench where there's plenty of dust particle moving around in the air and on most surfaces. Glasses and other protective or magnifying eyewear fit comfortable with it too, & I never used my big annoying HEPA mask after I got this.More > < Less

My son loves the neoprene mask and can wear it alone, but wears these filters when he is sanding paint off his old truck. Double layer of protection!! These can be washed, so we are really getting our money's worth. so much more effective than paper masks - why waste money on those!More > < Less

The filters are the most important part of the mask that I purchased. I could not be more pleased. I have Stage 4 COPD, & now am able to go places without fear of losing my breathe to fumes, pollen etc.More > < Less

About RZ Mask

Breathe Easy

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.
