A breakthrough in hygiene – just when we need it most

What if you could clean your airways the way you clean your hands? With FEND, you can.

FEND is a calcium-fortified hygiene mist that strengthens your body’s natural ability to trap particles and cleanse your airways.

Breathe in FEND before heading into work, boarding a flight, or making a trip to the store. Any time you would think to wash your hands, that’s a good time to use FEND.

Clean the air you breathe (in and out)

Every day we inhale between 100 million and 10 billion particles. FEND’s new hygiene protocol helps the nose to act as a better filter for these airborne particles – trapping them in our upper airways before they can reach our lungs or be exhaled back into the air.

FEND works for up to 6 hours and is safe to use as often as needed. We recommend 2 deep inhalations, 3 times a day.

Originally invented by a Harvard scientist during the anthrax scare

The original concept for FEND came about after our co-founder, Dr. David Edwards, a leading aerosol physicist, was brought to Washington, DC, in the aftermath of the anthrax scare to help officials find ways to protect the public from dangerous inhaled pathogens.

His research focused on strengthening the mucosal lining of the airways by coating it with naturally comprised aerosols. Years later, David and a team of scientists at Harvard and MIT figured out a way to make this underlying technology work with a simple nasal mist that could help suppress the formation of particles that can carry contaminants.

Our latest research shows that inhaling the FEND mist can reduce the amount of airborne particles in our airways for up to 6 hours.

Wash your hands. Wear your mask. Keep your distance. Use your FEND.

Because We Know You Want to Do Everything Possible to Stay Healthy


Update: Due to high demand, FEND is backordered. We are accepting orders and will ship as soon as possible. We appreciate your patience and will update you further upon receipt of your order with an anticipated ship date.

This starter pack includes all your essentials: a reusable Mister that includes a glass vial, 2 bottles of our advanced FEND solution, and a step by step process on how to use your new FEND system.

For best results we recommend regular use; 2 deep inhalations, 3 times per day. For use by an individual, 2 bottles will last approximately 2 months. A bottle of FEND is good for one month after opening. 

Take a deep breath and let your body do its job

Winter is approaching. The holidays are around the corner. Let’s all do our part to keep ourselves and those around us well. Adding FEND to your health and hygiene routine can help keep the air healthier and cleaner – for everyone. It’s an essential new tool to help us get back to the old ways of life we all miss

“Cleaning our airways of particles less than a single micron in size – the ones not effectively filtered by conventional face masks – is a new hygienic measure that can be of critical value to healthcare workers and to those of us returning to work and school.”

Dr. David Edwards, co-founder and inventor of FEND
