With every breath we take, we generate droplets in our airways. These respiratory droplets, some large and many very small, travel deep into our lungs and then out into the environment. When large, they tend to fall around us due to gravity; however, when small – less than 1 micron – they can remain in the air for several hours and travel in clouds around the globe as they spread from person to person.

Masks do a good job of catching and filtering large particles but the majority of particles we exhale are too small to be captured. They can seep through the mask and linger in the air, putting others at risk.

FEND, the new nasal hygiene mist, cleans our airways of particles that masks miss. It provides long-lasting hygiene – up to 6 hours per use – and can be used safely as often as you want (we recommend 3 times a day). It's an essential new tool in the hygiene arsenal.

The original concept for FEND came about after our co-founder, Dr. David Edwards, a surface chemist and aerosol physicist, was invited to Washington, DC, in the aftermath of the anthrax scare to help find ways to protect the public from dangerous inhaled pathogens. He had the idea that we might be able to strengthen the surfaces of our airway mucus lining by coating it with naturally comprised aerosols. Years later, he and his team at Harvard and MIT figured out how to make the underlying technology work with a simple nasal mist that would suppress the formation of particles that can carry airborne viruses and bacteria. Our latest research shows that inhaling the FEND mist can reduce the amount of airborne particles in our airways for up to six hours.
