Breath better, cleaner air.

Introducing the next generation face mask.

The 4C Air Nano Mask

The next generation in personal environmental protection.

Unparalleled Breathability

The 4C Air nano mask allows nearly 3x lower resistance than similar filtering respirators and masks.

Exceptional Protection

Thanks to innovative nanomaterial, the 4C Air mask filters up to 99% of airborne containments.

Trusted by Science

This new nanomaterial was developed by leading professors at Stanford University and has passed rigorous filtration testing standards.

THE POWER OF NANOTECHNOLOGY

Our patented nanofiber material allows the creation of a paper-thin filtration layer with superior protection from airborne hazards. The microscopic nanofibers block the most dangerous particles PM2.5 and below.

Happy customers and counting!
