Our Areas of Innovation

Personal Environmental Protection

Utilizing our patented BreSafe nanotechnology, we are developing the next generation of face masks and protective controls for consumers to improve personal environmental protection from airborne hazards and poor air quality.

Materials & Textiles

Our research team is focused on developing innovative new material and textile applications using nanotech. Our Nanomedia allows for countless new design applications.

Industrial & Consumer Filtration

We are developing nanotechnology material applications that improve upon existing filtration solutions in industries such as automotive, aerospace, healthcare, and HVAC. 

Environmental Sustainability

Our researchers strive to develop solutions to improve sustainability and leverage our nanotechnology to create alternatives applications that reduce waste.

Our Nanotechnology

Using nanotechnology developed at Stanford University, 4C Air has created a patented nanomaterial that is optimal for filtration applications.

Compared to traditional filtration material, 4C Air nanotechnology provides exceptional filtering of hazardous particles at PM2.5 and below while allowing impressively low air resistance. 

We continue to develop new applications for this revolutionary form of media in hopes to improve personal air quality around the world. 

Our Mission

9 out of 10 people in the world breath 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.
