OSR-M1C - Open Standard Industries
We started Open Standard Industries as an effort to address the shortage of safe, effective, and resilient masks for essential workers and consumers.
Made of medical grade silicone and a replaceable filter disc that jointly filter >95% of airborne particles, our OSR-M1 masks are durable, reusable, non-valved (filtering air in both directions to protect you and your neighbor) and easy to clean. They fit snugly around your nose and mouth, with multiple sizes and adjustable straps to achieve a fully customized fit.
Each mask you purchase comes packaged with five disposable filters.
