of us breathe air that’s dirtier and drier than we can handle.
FEND restores your body's natural ability to clean air from the inside.
A New Frontier in Airway Hygiene
The Hydration Science of Natural Salts
FEND’s innovative approach to hydration goes beyond traditional saline sprays. FEND salts go wherever salts sprays do not, hydrating those airways most at risk to dehydration. Hydrated airways also clean inhaled particles better.
The science behind FEND
Your airways are designed to filter the air you
breathe, but dryness and airborne pollutants can disrupt their natural defense system. FEND’s precisely engineered mist works at the source—hydrating and strengthening your upper airways for cleaner, healthier breathing.
How FEND works
FEND’s calcium-enriched mist pulls water from epithelial cells through osmosis, restoring the natural hydration your airways experience during slow, nasal breathing. Unlike sodium, calcium moves passively and slowly into surrounding tissues, keeping your airways hydrated for 4-6 hours—safely and effectively.
Backed by Science
FEND’s science is backed by
multiple peer-reviewed articles published in leading scientific journals,
highlighting its role in improving airway hydration and cleansing.
Hydrating the airways daily is the missing link in what we’ve considered till now effective whole-body hydration.
A Trace of Magnesium: Small but Essential
Breathe better with FEND
Magnesium is an essential mineral for your airways, yet many people don’t have enough of it. FEND includes a precisely measured trace of magnesium to help restore balance and support airway hydration.
Like calcium, magnesium stays in your airways longer than sodium (found in normal saline). This is because it moves around airway cells rather than passing directly through them, allowing for extended hydration and better airway support.

Dr. David Edwards
Dr. David A. Edwards is a globally recognized scientist and innovator in airway hydration and respiratory health. A member of three national academies in the U.S. and France, he served as a Professor of Bioengineering at Harvard University (2002-2019). Currently, David is an adjunct professor of medicine at Johns Hopkins Medical School.
His groundbreaking work in respiratory healthcare, including the discovery that led to Inbrija® (inhaled levodopa for Parkinson), continues today as he explores the immediate and long-term benefits of airway hydration for overall respiratory health.
