Everest Testimonials:

I've been using the Silicone cannula for 3 years and really would find it hard to use the old plastic ones; I couldn't stand the smell of the plastic ones, I became very nauseated. They last well over a year; I save the prior year ones for back up in case I accidentally damage the one I have on. I had surgery last month and used my silicone cannula. The nurses were very interested in it.

The Everest nasal cannula has been nothing short of an answered prayer for me. I searched the Internet for several years before I finally stumbled on to your website. The reason I searched was because I am allergic to rubber and latex products. It was a nightmare including using steroid creams to keep the rashes from becoming worse. This cannula is so soft and comfortable and no rash! Thank you for making my life so much better.

Thank you so much for allowing me to share with others the wonderful experiences I have had with your product. Back in June 2010 I was hospitalized with COPD. I was given the standard PVC Cannula and they worked for about two years. I then became allergic to them. My supplier told me there was nothing else they could provide. Well, I went to my trusty GOOGLE and simply asked for cannulas made from anything other than PVC. Up came information on your product and the wonderful video. I contacted your office in Canada and was then referred to your office in Nevada. Beverly even gave me her vendor number for Apria and still they denied being able to supply me. I then ordered them myself and have been so totally satisfied. I have ordered three total and will be ordering a couple more this week. Your ads say they can last for a year; well mine have lasted much longer. I take great care of them and sterilize them regularly. I'm going on two years of use.

Now for answers to your questions.
1. Began Oxygen Therapy in June, 2010.
2. Initially had no problems.
3. The only other one I have tried is the PVC that Apria supplied. Didn’t like anything about them. They cause my neck and ears to break out in a rash.
4. Tried my first Everest in March of 2012.
5. I use the Everest all the time. Comparison of my situation is amazing. No more rash break out.
6. I like the way it fits in my nose and the fact that I seem to receive a better flow of oxygen than I did with the PVC. Nothing bothers me about Everest.
7. The best advice I could give is to definitely try the Everest. It does cost me and the PVC are part of the oxygen supply package, but it's a cost I don't mind making. Only wish Medicare would pay for some or all of it.

You have a wonderful product and more should know about it. Even my doctor had never heard of your product. They do now as I have provided contact information to them.  

My father, before he passed, suffered from severe COPD/Emphysema and was on oxygen 24 hours a day. Due to a skin allergy he was unable to use regular PVC nasal cannulas without have severe skin weeping, swelling, and rashes. He was forced to wrap his cannulas in a thick cloth tape that rubbed his face and ears dry and raw.

Through some good old-fashioned Google searching I was able to find the Everest 100% silicone nasal cannulas. His skin cleared of any problems from the tape and he experienced no further problems from wearing oxygen. He also liked the extra weight of the cannula as it rested more comfortably on his face.

He took his cannulas to all of his doctor appointments, hospital visits; ER visits and was the last thing he wore before he passed.

We are all grateful, as was he, that we were finally able to find something that he could use after suffering skin problems with cannulas for years. It made such a difference that when in the hospital he labeled his cannula as the only product he could use and actually got into an argument with staff who wanted to change it out for a cheaper product.

The only complaint I have is that it wasn't available more widespread! I believe there are a great many people out there that could highly benefit from it.

A huge thanks to Everest for a fantastic product.

1. I started oxygen therapy about eight months ago.
2. The initial problems involved and are growing is a severe allergy to all plastics and gasoline based fabrics and plastics. (A polyester allergy started shortly after starting therapy and any silicone is no better. It's a lose-lose.)
3. I use a nose cup cannula and have created pure cotton "sleeves" for the cup and tubing because no plastic can touch my skin or I get hives and have trouble breathing, which defeats the purpose.
4. I tried Everest shortly after first starting OT. My initial reaction was a severe allergic reaction.
5. I alternate the Everest cannula when I'm desperate. To be honest, I'm trying to figure out a way to never use a cannula again because there may come a time when it will become impossible to continue OT.
6. The only thing I like about Everest is the ability to boil it.

A very long and useful life of the Everest Silicone nasal cannula is guaranteed.

Please read this information about the Everest Silicone Nasal Cannula BEFORE deciding to buy


Both variations of the Everest are available in two lenghts, 47. 2 inches long or 1.2 meters and 70.8 inches or 1.8 meters long. This is optimal for use with a backpack or a small ambulatory oxygen device.

It is typically NOT long enough to be able to move freely in a kitchen, living room or to take a shower. The Everest will probably not be your ONLY nasal cannula that you use. It will just one of several that you use on different occasions and in different situations.

We also have 100% silicone extension tubes in two different lengths, 39 feet and 32 feet long for better moving around.

Cleaning / Useful Life

Both variations of the Everest are manufactured to be used over a very long period of time. We give a one year money-back guarantee on the cannula. However, YOU are responsible for cleaning the cannula. We recommend placing the cannula in hot boiling water for 20 minutes at least once every two weeks.

After boiling, let the cannula cool down and then run oxygen from your concentrator or tank through the cannula until all moisture has been removed. Not removing all moisture may cause some whistling of the cannula. If you hear any whistling (or if your dog hears the whistling), all that is necessary is to dry out the cannula some more; let more oxygen flow through the cannula until the whistling has stopped.


The Everest has a standard cone shaped connector that fits on almost all oxygen concentrators and bottles.

Nasal Prongs

The nasal prongs have a 10 mm or .40 inches separation. This is an average size. It might be too small for some very large men. MEASURE the distance between the two prongs of the cannula that you are using right now and compare this to the .40 inches of the Everest. Is this distance acceptable for you or not?

The prongs are formed straight up-and-down vertical to the tubing. No other forms of nasal prongs are available at this time.

The nasal prongs can be pulled out of the tubing, cleaning, boiled in water or sterilized, and reinserted into the tubing many times. We encourage you to clean the nasal prongs frequently.


The Everest is a SINGLE tube oxygen cannula. It will NOT work with the Helios portable systems that need two tubes to function properly or with any other system requiring two (2) tubes.

On Demand / Triggered Systems

The Everest cannula cannot be guaranteed to work with on-demand / triggered systems.

We have cases where it does work and other cases where it does not work. At this point in time, we cannot predict with any certainty when it will work and when it will not work. We have had satisfied customers with the Spirit 300, 600 and 1000 systems, and then customers who say it does not work with such systems. Since the various manufacturers have refused to work together with us, we are unable to determine exactly why this situation occurs.

Flow Rate / Noise

The Everest cannula can deliver up to 10 liters / minute of oxygen for those patients who need it. HOWEVER, this is at a very high noise level of 56 decibels.

The Everest is LOUDER than a normal PVC cannula. At 3 liters / minute, the Everest gives off the sound of a refrigerator running in the background, or 40 decibels vs. 33 decibels for a PVC cannula. If you a very sensitive to noise, then the Everest is NOT for you.


We give a one year money-back guarantee on the Everest silicone nasal cannula. If you are for any reason unsatisfied with the product, please just send it back and we will refund 100% of the purchase price.


  • Silicone is a soft material, and the Everest stays soft even at very low temperatures (minus 40 degress.) This means that in winter, while walking outside in the cold, or sleeping with a window open, your Everest cannula stays soft on you ears and cheeks.
  • Silicone is softer on the pressure points on your ears or cheeks.
  • Silicone does not cause or exacerbate allergies like PVC cannula.
  • Silicone does not stink of plastic as do most PVC cannula.
  • Silicone does not give off the dangerous gases as does PVC cannula.
  • Silicone has a very long useful life. We already have clients who have been using an Everest for more than 3 years are still happy with their Everest.


  • Silicone weighs somewhat more than PVC, and therefore is somewhat heavier than a PVC cannula.
  • Silicone can build up static electricity and cause some dust to stick to the cannula. This can be removed by using a wet cloth with some mild soap on it.
  • Silicone is somewhat sticky. This can disturb some women in particular since hair might stick to the cannula and cause an uneasy feeling. The stickiness is reduced every time the cannula is boiled in water.
  • Silicone is a porous rough material and causes more turbulence in the air flow through the cannula than does PVC. This results is a higher level of noise than a normal PVC cannula. (We are working on ways to reduce this problem, but for the moment, the Everest is louder than a normal PVC cannula.)
