Our Mission

9 out of 10 people in the world breathe dangerous air that exceeds acceptable WHO limits.

According to the WHO, the combined effects of ambient (outdoor) and household air pollution cause about seven million premature deaths every year, largely as a result of increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections.

4C Air is devoted to changing this. Our goal is to improve the lives of those affected by poor air quality by providing safer, cleaner air through innovative nanotechnology products and solutions.

Our Story

4C Air was founded in 2015 by Professor Yi Cui and Professor Steven Chu of Stanford University.  Through hard work and innovation, 4C Air was able to develop a new nanomaterial ideal for use in filtering applications.

Today, the company continues to work on developing nanotechnology products and solutions to provide the world with better protection against harmful airborne particles and poor environmental conditions.
