Cystic Fibrosis (CF) is a genetic disease that causes severe and constant lung infections and irreparable lung damage over time

At Cambridge Mask Company, we provide our products to people with Cystic Fibrosis (also known as CF) on an almost daily basis.

Approximately 30 000 Americans have Cystic Fibrosis and around 1 000 new cases are documented each year. While millions and millions of people carry the mutated gene, to be affected by the disease a person must inherit two of the genes. In the USA, studies suggest that around one in 29 White Americans carry the CF gene.

It cause excessive sticky, this mucus build-up in the lungs, pancreas and other organs. The mucus in the lungs clogs up airways and traps pollutants and bacteria, which can lead to infections, lung damage and ultimately respiratory failure. Mucus in the pancreas prevents digestive enzymes from being released which our bodies need to break down food and absorb vital nutrients.


Limited Edition 65Roses Mask

By Jennifer Ronnenberg

“Breathing is something people with cystic fibrosis do not take for granted, having a mask that protects us and represents something that is a part of who we are is wonderful; it’s not something we’ve had before”

Earlier this year we partnered with Jennifer Ronnenberg to create this limited edition mask design. 10% of profits are donated the the Cystic Fibrosis Foundation.


Cystic Fibrosis can be an alienating condition, especially before the advent of the internet, as sufferers can never meet in person. Cross-contamination can happen with extreme ease between two people with CF, as they grow bacteria in their lungs that is mostly harmless to people without the condition but can be transmitted easily between two affected people.

Meetings and conferences are places where cross-infection could occur, so even at cystic fibrosis-related events, there should only be one person with CF in attendance at a time.


Cambridge Masks block particles down to size PM0.3, and provides the benefit of blocking many microbes including bacteria such as pseudomonas and fungus and fungal spores, although these can be of variable size. As such it should provide a barrier as long as the mask is a good fit.

Cambridge Masks have been independently tested by Nelson Labs, USA, which confirmed almost 100% of particulate pollution, bacteria and viruses were successfully filtered when tested. This test involves testing the mask against penetration by a fine spray of sodium chloride (salt) and is the accepted standard for respirators design to protect against particulate matter such as pollutants from traffic.
