Our elevation system is available for weekly rentals with a minimum rental term of 4 weeks. If you decide to keep the system at the end of the rental period, the rental amount paid can be applied to the purchase price.

Our web store allows for automated shipments within the USA and Canada.  If you’d like to ship outside of North America,  please contact us and we can arrange that for you.

Mountain Air Cardio is geared towards athletes and mountaineers looking to improve their cardio performance.  Mountain Air Health is geared towards those looking to lose weight.  The products from either website are in fact identical and trigger the same physiological responses (improved cardio, increased metabolism, reduced appetite). MountainAir^® is a registered trademark and refers to the branding of the product.

Yes! Our air separation technology has been around for many years and this hardware has been used by 23 different research institutions in the US alone including the Mayo Clinic and Harvard University.  You can check out some relevant medical studies at our scientific research download page or just Google the search term, “high altitude weight loss” and you’ll quickly get an idea as to the effectiveness of this type of therapy.  Every person responds differently to altitude so results may vary.  Note that the full physiological effects don’t start to appear until the user has acclimatized to the target altitude of 8,000-10,000 feet.

One of the best aspects of our system is that once it is set up, it takes no more time away from you. It isn’t ‘one more thing’ that needs to be scheduled, fit in, or made into a daily habit. Once the decision is made to adopt the MountainAir^® system, no other physical or mental energy is wasted trying to make yourself live up to the commitment – that happens all by itself by simply going to bed.

It is well documented that living at high altitudes causes a reduction in appetite and an increase in metabolism which makes it easier to lose weight. As reported in Scientific American, in the US there is a 4-5 fold increase in obesity prevalence at low altitude as compared with the highest altitude category, even after controlling for diet, activity level, smoking, demographics, temperature, and urbanization.  When you sleep at altitude, most users experience an increase in leptin levels, a decrease in grehlin levels, and an increase in basal metabolic rates.

In addition to slowly ramping up the initial elevation, the automated controller (PAT PEND) monitors oxygen, temperature, and humidity levels within the tent and makes adjustments as needed. It also logs your daily usage and elevations achieved.  The controller is the ‘special sauce’ of the system and is critical to the safe, comfortable, and effective use of MountainAir^® .  Please visit the Apple App store to download the Mountain Air Health companion app:

Every person is different, but studies have shown an average weight loss of 1 pound (0.45 kg) of fat per week after reaching the target of 8,000-10,000 feet.  Results will vary by individual.

People with the following conditions should not use MountainAir^®: hard-to-control hypertension, heart failure, anemia, symptomatic coronary disease, obesity hyperventilation syndrome, severe obstructive sleep apnea (OSA), chronic obstructive pulmonary disease (“COPD”), cardiac arrhythmia, lung disease, sickle cell disease, patients who require oxygen therapy, or women who are or who may be pregnant. Users should seek their own professional counsel for any medical condition or before starting any weight loss plan.

Yes!  If the system were to fail while you were using it, the enclosure would revert to whatever your ambient elevation is.  The automated controller monitors environmental parameters once per second and if anything is out of specification, the air unit is automatically shut down.  This safe and effective, and is the same system currently used by thousands of elite athletes to increase their cardio performance.

With our system, you increase the elevation gradually over a 1-2 week period so users have time to adjust and do not experience mountain sickness.  In contrast, if you go to a higher elevation rapidly (such as flying from a coastal city to a Colorado ski area), some travelers experience mountain sickness. This is because the body has not had time to adjust to the higher elevation. However, over a period of days, your body naturally adjusts and symptoms of mountain sickness are avoided.

Inside the tent, the system produces a sound level of approximately 40 dBA @ 1m which is approximately equal to the noise of a small desk fan.  The air separation unit itself runs at approximately 55 dBA @ 1m so we recommend that it be installed in an adjacent room or hallway.  MountainAir^® ships with a sufficient length of air hose to allow for this.  The low noise levels inside the tent are thanks to our silencer installed at the end of the air hose.

The temperature inside the tent is approximately 5-10° higher than ambient air.  Our tents stay cooler than older systems because fresh air is continually drawn into the tent.

Our tent-based systems can be set up in under an hour by the average user. Each system ships with an illustrated, easy-to-follow set of instructions.  We also offer telephone support during mountain time office hours at the number shown on our contact page.

No. MountainAir^® operates on a normal household plug and consumes approximately 5 amps (less than a toaster). With typical usage of 7-8 hours/day, this works out to an electricity bill increase of approximately $15-$30/month depending on your local electric costs.

MountainAir^® is sturdy and reliable and comes with a 12-month warranty against manufacturer’s defects.

There is very little maintenance required for the air separation unit. A small filter is changed after the first year of operation or roughly 3,000 hours based on average usage of 8 hours per day. There is also an inlet filter that can be manually cleaned twice per month.  There is no major maintenance required until 10,000 hours of service (3-4 years of using the system each night).

No study has shown an upper limit to weight loss but data shows at least 90 days of continued weight loss for most users. After that, the appetite suppression effect can diminish with some users. Should that occur, sleep without the aid of the system for two weeks, and then when you begin sleeping in the tent again, you will regain the appetite suppression effect.

Some users report the increased need to urinate during the night because of the corresponding increase in your basal metabolic rate.  This is a sign that the system is working!  An additional effect with most users is that the body produces more red blood cells which results in a higher cardio capacity. This effect is well-known among elite athletes who use this system to increase their performance. This harware has been sold to over 3,000 athletes for this reason.

Weight gain or loss is part of a dynamic process of energy balance and no weight loss or gain is permanent. We recommend combining MountainAir^® therapy with a healthy diet and exercise plan for best results.

No. MountainAir^® is considered a wellness device.
