The natural mist solution that cleans the air you breathe

Everyday airway hygiene

Every day, you breathe in billions and billions of particles. To keep us healthy, our airways need regular cleaning, just like any other part of our bodies. We call this airway hygiene. It's a new thing. And yes, it actually works.

Using a specially formulated micro-mist, FEND cleanses your upper airways with vital salts, preventing dirty air from traveling deep into your lungs or back out into the environment.

Benefits last up to 6 hours

A daily ritual that's safe and drug-free

You can use it as often as you need, and it's safe for kids, too. We suggest three times per day.



+ A dash of salt preservative

Award-winning design meets world-class science

Our system gets FEND mist to airway mucus surfaces that are critical to the body’s immune defense against inhaled contaminants.

It’s like washing your hands or brushing your teeth. FEND mister and solution work perfectly together to help your body clean the air you breathe.

Invented by David Edwards

Long-time Harvard faculty member

David is one of the world’s leading respiratory health scientists. He’s been at the forefront of airway hygiene research and application for decades – from working with the US government in response to the 2001 anthrax attacks, to his mission today of helping the wider world breathe safely with FEND.

“FEND Is a new approach to keeping us clean in a world that has dirty air. FEND introduces hygiene for our airways in a new way - with salts that are in the body and a mist that gets them there.”

Professor Robert Langer, member US National Academies Science, Engineering and Medicine

We believe everyone deserves to breathe clean air

Access to clean air today is unfair. To help those who need it most, we are partnering with the new charity Next Breath. See The Next Breath manifesto co-authored by our founder and over 30 leading scientists worldwide, including three Nobel laureates.
