Founded in 2015, 4C Air is devoted to bringing clean air through innovative nanomaterials. Using technology developed at Stanford University, we are developing products and solutions for the most hazardous air pollutants, PM2.5. We have products developed for personal and home use and are actively exploring filtration for automotive, HVAC, clean room, and medical uses.
