From the Big Game in LA to the world.

We are thrilled to have been invited to Los Angeles to keep everyone’s airways clean and hydrated during the Rolling Stone Party on the eve of this year’s Super Bowl. Our presence at the Big Game gives us a chance to share that FEND has a very special place in the performance and recovery of high-performing athletes and performing artists.

In the light of our participation in the pre-game activities for the big game in LA, we'd like to extend a warm congratulations to Mickey Guyton, who is singing the National Anthem at Super Bowl LVI.


Helping elite athletes and coaches

“Upper respiratory illness is the most common non-injury reason why athletes show up at sports clinics. Among elite athletes the breathing challenge is endemic — with symptoms ranging from congestion to sleep apnea. Poor breathing disrupts sleep, recovery, and performance. Now there’s something to do about it. Since I began using FEND I travel without congestion for the first time in years.”

Body coach for Tom Brady and elite athletes everywhere

Hydrating to perform better

“I sang the other day and used the FEND spray, and normally when I'm singing I have to chug water. The whole session I'm having to take breaks because I'm chugging water so much. I felt the effects immediately. I didn't have to drink so much water – I was totally fine.”

How to FEND for optimal performance

As you begin your journey to better breathing, we want to make sure you're FENDing properly. Our team put together a couple of quick videos walking you through the unboxing of your FEND and how to ensure consistent results from your device.

Getting started with Jami

When you first receive your device, it will take a few pumps to get the solution to create your first mist – just like a new bottle of soap! Jami shows you how in this getting started video.

How to FEND with Johnny

To get a consistent mist, you'll need to squeeze firmly and hold with consistent pressure. There are plenty of ways to do this and Johnny shows you a couple in this how-to video.


Our lungs need hydration to clean our air and get the oxygen we need. Dehydration frequently happens. It happens fastest when we exercise.


Dry airways restrict the air flowing to our lungs. FEND before you exercise to perform better.


Dry airways fail to clean the air we breathe and become inflamed. FEND after you exercise to recover well.

Breathe better for life.

What people are saying.

"I am an RN and use my fend at least 2x a day and will continue to recommend it to my colleagues and patients."

-Jeanne M.
FEND customer

"Hydrating the airways daily is the missing link in what we’ve considered till now effective whole-body hydration."

-Dr. Dennis Ausiello
Jackson Distinguished Professor Médecine

"Obsessed. I just put one everywhere I have hand soap or hand sanitizer: Bathrooms, kitchen, desktop, backpack, and my work bag. Gave one to a friend and one to my parents. No longer sneeze when I'm near my daughter's four guinea pigs!"

Frequently asked questions.

  What is FEND?

Backed by science, FEND is a new hygiene protocol that cleanses and hydrates the upper respiratory airways to strengthen the body’s natural ability to help keep the lungs cleaner and healthier. FEND uses a proprietary calcium-enriched saline solution delivered in perfectly sized particles that exit the device in a mist that is inhaled through your nose. When inhaled deeply, it hydrates your upper airways capture and eliminate airborne contaminants before they reach your lungs. In addition, FEND helps reduce the number of airborne contaminants you exhale back into the air.

  How is FEND different from a typical nasal spray?

The FEND Mister is not a nasal spray. In fact, it’s not inserted into your nose at all.

Unlike nasal sprays, the FEND System is designed to generate a gentle, safe mist that is inhaled into the upper airways vs. inserted and sprayed into the nose.

Similar to how a humidifier works by creating a mist from water, the mist is created from the proprietary calcium-enriched saline solution. And unlike most nasal sprays, it is drug-free.

The reason we use the FEND Mister device is because the mist particles derived from the solution are smaller than what a nasal spray bottle creates. This enables the solution to stick to the mucus lining in your nose, trachea and main bronchi, which are just at the top of our upper airways. Typically, when we breathe, talk, or cough, the airflow is so strong that it breaks the mucus into little droplets, like wind makes sea mist (at the beach). FEND prevents this break up from happening. FEND rejuvenates the mucosal lining to help it capture and eliminate airborne particles.

  How do I use FEND?

To get started, you'll have to "prime the FEND" (sort of like when you get a new soap dispenser!). Check out this video for a quick how-to. Then, here's another quick video to show how to actually use and hold the new design properly.

A few additional tips and tricks for using your FEND:

1. Squeeze the top and bottom together firmly and hold for a mist. You may feel a small click when you press the FEND together all the way and you’ll notice this ends the mist. This is normal, but if you press it together too fast you won’t get the full mist.

2. You’ll need to hold the FEND upright for it to work. For best results, make sure your FEND is held upright and is tilted downward slightly. If used upside-down, you may need to re-prime the FEND by pumping it a few times to get a mist again.

3. You may experience what we call a “drool” where a bit of liquid builds up near the nozzle. Simply shake out the “drool” to allow the mist to come out.

  How often should I use FEND?

We recommend using FEND every 6 hours, up to 3 times a day. Typically, when you wake up, at some point during the afternoon, and before you go to bed. Regular use of your FEND helps to continually strengthen the mucosal lining, creating a strong filter against small airborne contaminants.

It has also been shown to aid in performance and recovery during periods of activity. FENDing before a workout and a bit after for recovery is also recommended.

Because FEND is literally just salts commonly found in ocean water, there is no risk to "overdose" with FEND and can be used as often as needed.

  How quickly does FEND take effect?

FEND begins to take effect within about 15 seconds of use

  Is FEND safe? Can my child use it?

FEND is a safe, proprietary calcium-enriched saline solution, and is drug-free. Safe for anyone to use, kids included. If you have any concerns, please consult your doctor before regular use by your child.

  Where can I find published peer-reviewed studies on FEND™?

FEND™ was first developed by Dr. David Edwards, our founder, as a response to risks created by anthrax at the request of The United States Department of Homeland Security. In 2020, in response to the global Pandemic crisis, Dr. Edwards and a team of scientists at Harvard and MIT applied that science to create FEND™. The FEND™ system includes a patented Mister device, which uses a proprietary calcium-enriched saline solution.

FEND's effectiveness has been published by peer-reviewed journals and several safety studies conducted before being introduced to consumers. You can find one recently-published in the Molecular Frontiers Journal here: In addition, you can find more studies and articles about FEND™ on our site:
