==Recommendations==
I believe that the [[AltoLab]] system is the most cost effective solution. For those wanting a sleep based system, Higher Peak offers the best value.
==Rebreathers==
Chemical generators use a chemical reaction to either remove oxygen from the air, or to remove the carbon dioxide from the air that you exhale, which is then breathed again. These systems are cheaper to purchase, but require the ongoing purchase of the chemical cartridges. These systems are only used for intermittent trainingExposure, not for sleeping.
===AltoLab===
[[AltoLab]] uses a stack of AltoMixers, with each AltoMixer diluting the oxygen to provide the equivalent of 5,000 ft. The AltoLab system also requires a CO<SUB>2</SUB> scrubber which has to be replaced and lasts 2-3 hours. The running costs would be $10-15 per hour, but you can buy the CO<SUB>2</SUB> scrubber in bulk, reducing the cost down to $1 per hour; see [[AltoLab]] for details. http://www.altolab-usa.com/
* Everest Summit, $5,550. Provides 12,500 ft, or 21,000 ft with a $200 adapter. (Looks physically identical to Higher Peak MAG-10)
* HYP123, $5,500. Provides 12,500 ft, or 21,000 ft with a $200 adapter. Upgrade to HYP100.
* HYP100, $4,700. Provides 9,000 ft, or 14,500 ft with a $200 adapter. (21,000 ft for IHT IHE with add on.)
* Conversion for use in exercise - $700
* Tents - $350+
