Questions about FEND™

+What is FEND?

Backed by science, FEND is a new hygiene system that cleanses the upper respiratory airways to strengthen the body’s natural ability to help keep the lungs cleaner and healthier. The FEND system includes a patented Mister device that uses a proprietary calcium-enriched saline solution. The FEND Mister device then creates perfectly sized particles that exit the device in a mist that is inhaled through your nose. When inhaled deeply, it helps 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. 

+Why do I need a FEND system?

 Every day, we breathe billions of airborne contaminants in and out. Some of these contaminants enter our upper respiratory airways.

When a contaminant enters our nose or mouth, our upper airways act as a natural air filter for our bodies, keeping us well. This is possible because the upper airways are lined with mucus.

The mucosal lining is the key player in all of this. The mucus naturally captures airborne contaminants and ensures they are safely eliminated (by swallowing them into our digestive system). Sometimes though, the mucosal lining wears down, whether by stress and anxiety, age, pollution, or an over-abundance of airborne contaminants.

FEND helps strengthen our body’s natural ability to cleanse and strengthen the mucous, preventing contaminants from finding their way into our lungs and be exhaled back into the air.

+How does FEND work?

The FEND system includes a patented Mister device that uses a drug-free calcium-enriched saline solution. The FEND Mister device then creates perfectly sized particles that exit the device in a mist that is inhaled through your nose. When inhaled deeply, it helps 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 the FEND Mister different from a typical nose spray? 

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

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.

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.

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.

Questions about how to use FEND

+How do I use FEND?

FEND is easy to use. Simply tip and hold still the Mister at a 45-degree angle, 2-3 inches from your nose, positioned slightly under it; it will produce a cloud near your nasal passages. Take two deep breaths through your nose, for about 4-5 seconds each time. When you are able to hear the sound of your deep inhalation, that means you are doing it right, filling your upper airways as completely as possible each time. When inhaled correctly, FEND will last up to 6 hours. Now, you’re FENDed!

+How do I know that I've inhaled enough of the FEND mist?

The FEND Mister is designed to generate 10 seconds of a dense mist cloud every time you turn it over to activate use. Hold the Mister close to your nose and take two deep breaths. If for some reason you only take one deep breath, it is safe to activate a second (or third) cloud and take another deep breath. 

+How often should I use FEND?

We recommend using FEND every 6 hours, up to 3 times a day. Regular use of your FEND helps to continually strengthen the mucosal lining, creating a strong filter against small airborne contaminants.

+ What is the benefit of using FEND? Is the benefit for me or more for others?

We are all bombarded daily with airborne contaminants. The benefit of using FEND regularly is FEND rejuvenates your mucus lining and strengthens your body’s natural ability to keep airborne contaminants from finding their way into your lungs.

Just as washing your hands helps protect you, it also helps you remove any contaminants from your hands so not to spread to others. FEND is a new patented hygiene system for the upper respiratory airways that helps keep your lungs clean, AND reduces airborne contaminants from being exhaled into the air.

+Is it better to use FEND before or after I am with people or in public?

We always recommend using FEND on a daily basis, up to 3 times per day regardless of your plans. With each use, FEND lasts up to 6 hours.

+ If I am taking a COVID test, can I still use FEND?

We recommend you use FEND after you take any test that involves a swab in your nose or throat.

+If I sneeze or blow my nose, do I have to re-use FEND?

No. Once you administer the mist cloud, it goes to work immediately, calming and strengthening the mucosal lining of your upper airways to capture and eliminate airborne contaminants - helping you inhale and exhale cleaner air. Sneezing and blowing your nose will not diminish this effect.

+Where can I use my FEND device, indoors or outdoors?

FEND can be used indoors or outdoors - in fact, anytime and anywhere. It is light and portable so you can take it with you. When used outdoors, best results are achieved when you are protected from the wind.

 

Questions about the FEND Mister device and solution

+ How do I install the batteries:

Turn and release the silver top to reveal the battery chamber. Install two AAA batteries according to the +/- markings shown by the openings. Press the top down and turn it clockwise until fully closed. Turn the Mister over so you can see the bottom. The green light should turn on indicating the batteries are working.

+ How do I create a mist cloud?

Tip the Mister and observe the cloud. This is created by a metal mesh at the top. You may notice a green light at the bottom indicating operation. FEND Mister will run for 10 seconds before it stops automatically. This is a power saving feature. Tilt again to restart.

+How should I care for the Mister device?

Over time, the calcium-enriched saline solution can build up on the mesh inside the Mister device. The following will clean and reset your device between bottles of solution and help care for your FEND Mister. 

1. Detach the glass vial from the bottom of the Mister and fill it half-way with fresh water
2. Heat the half-full glass vial in a microwave for 10 seconds (Never put the Mister into the microwave). Make sure the vial is a comfortable temperature before handling
3. Re-attach the vial, then tip the Mister to run the device. You should see a full mist cloud come from the device. If not, repeat the previous steps
4. Fill with fresh FEND solution and enjoy!

+ How should I store my Mister device?

DO NOT leave the FEND Mister in the hot sun.

When traveling, it is recommended to remove batteries and detach the vial, then close the vial with the provided cap. 

 +Troubleshooting

What should I do if there is no mist, or the mist flow is weak

Tilt the Mister and check that there is a green light underneath. If there is no green light, check to make sure that the top is securely fastened. It is possible to attach the lid and leave a gap.  Make sure that the lid is engaged at three points, and that it is fully tightened.

If the top is secure and there is no green light, you may need to replace the batteries Make sure battery polarity (+/-) is correct.

If there is a green light with fresh batteries, your mesh may be clogged. This can happen from the FEND solution build up on the mesh. The process below will help to unclog and keep your device clean between bottles of solution:

Use this convenient approach: 

1. Detach the glass vial from the bottom of the Mister and fill it half-way with fresh water
2. Heat the half-full glass vial in a microwave for 10 seconds (Never put the Mister into the microwave). Make sure the vial is a comfortable temperature before handling
3. Re-attach the vial and tip the Mister to run the device. You should see a full mist cloud come from the device. If not, repeat the previous steps
4. Fill with fresh FEND solution and enjoy!

+ I see some particles in my solution. Is this safe?

If particles are found in the FEND solution, it’s possible they are calcium or salt particles. However, the Mister device has a mesh filter that would prevent any particles from making it through the mesh. While we do have a very small amount of a preservative in our FEND solution (called BKC) to improve the stability of the solution, the product has a 30-day shelf life after opening the bottle. If it has been open for that period of time or longer, that could be the cause. If the product goes beyond its shelf life, we recommend you replace the solution and then clean the glass vial and Mister device before using again.

1. Detach the glass vial from the bottom of the Mister and fill it half-way with fresh water
2. Heat the half-full glass vial in a microwave for 10 seconds (Never put the Mister into the microwave). Make sure the vial is a comfortable temperature before handling
3. Re-attach the vial and tip the Mister to run the device. You should see a full mist cloud come from the device. If not, repeat the previous steps
4. Fill with fresh FEND solution and enjoy!

As always, if you are concerned, please email the FEND Customer Care team at hellofend@sensory-cloud.com and we will address your question and concerns directly.

+ Does FEND have a preservative in it?

FEND has a very small amount of a preservative called Benzalkonium Chloride (BKC). This is preservative is commonly used in nasal saline and nasal drug products. We have included BKC to give our FEND solution better stability once opened for use.  The amount (0.1%) of BKC in your FEND solution is within the safety range of BKC, which is why you can find it on the FDA Inactive Ingredient list for nasal products at this same concentration. Even multiple administrations of FEND will not increase this concentration of BKC, since for every microgram of BKC you administer with FEND you administer 1000 micrograms (or 1 milligram) of purified water! So, while at much higher concentrations BKC — like other substances that attack microbes — can be unsafe, it is perfectly safe in FEND, and of course helps keep FEND from accumulating germs once opened.

 

Questions about Product Safety

+ Is the FEND solution safe?

Our FEND solution consists of two naturally occurring elements: calcium and sodium. What makes it unique is the proprietary proportion of each in the solution. The solution does NOT contain any drug element and is safe to use. It also includes a very small amount of a preservative called Benzalkonium Chloride, a preservative commonly used in nasal saline products. We have included BKC to give our FEND solution better stability once opened for use.  The amount (0.1%) of BKC in your FEND solution is within the safety range of BKC.

+ How often is it safe to use FEND?

For the most efficient use of FEND, we recommend inhaling the mist deeply two times, which lasts up to 6 hours.  FEND is safe to use more frequently if needed.

+ Is FEND safe to use with my child?

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

+ Can FEND help with allergies?

Airborne contaminants can carry many different elements, such as smoke, pollutants or allergens. In all cases, FEND strengthens your body’s natural ability to help keep the upper respiratory airways and ultimately, your lungs cleaner and healthier.  FEND is a drug-free, safe to use upper respiratory airways hygiene system. However, if you have any specific concerns based on your personal situation, we recommend you consult your doctor before regular use.

+ Is FEND safe to use if I am pregnant or have another condition, such as hypertension, diabetes for example?

FEND is a drug-free, safe to use upper respiratory airways hygiene system. With all medical conditions, we recommend consulting your doctor before regular use.

+ How should it feel after inhaling FEND?

When the mist from the FEND device is properly inhaled (two times, deeply), we often hear people say they feel their nose is a little moist, or there may be a little tingle. inside their nose.  FEND is drug free and safe. However, if you have any symptoms that persist or seem out of the ordinary, we always recommend consulting with your doctor if you have any concerns.
