LiveO2's Extreme is a single-station system that pairs oxygen-rich air with simulated altitude air for use while you exercise, with an altitude setting its product page lists as adjustable from 10,000 to 22,000 feet. US builds on the standard warranty run $7,000 to $9,075 on LiveO2's store, and the exercise equipment is not included.

LiveO2 calls the Extreme its recommended single-user system for home training and clinics alike. In the brand's words it combines oxygen-rich air with simulated altitude adjustable from 10,000 to 22,000 feet, though the FAQ on LiveO2's homepage gives 10,000 to 19,000 feet, so confirm it before ordering. The system includes one reservoir with a single training station, one or two air separators that refill it, a premium and a standard mask kit, a pulse oximeter, LiveO2 training app access and New User Coaching, which LiveO2 lists as a $500 value. The bike or other equipment is yours to supply: LiveO2 states its equipment is only intended for use with exercise or physical challenge, and that there is no effect from stand-alone use.

In LiveO2's range, the Extreme is the single-user adjustable-altitude step. With the frame kit selected, as both product pages do by default, LiveO2's store shows the Adaptive Contrast System at $5,150 and the Extreme at $7,075. The Adaptive Contrast has a fixed 10,000-foot setting that, in LiveO2's words, cannot increase the simulated altitude, and includes only a standard mask kit. The Dual User Extreme starts at $11,825 and adds a second training station. On the Extreme itself the choice is 10 or 20 L/min: one or two 10 L/min air separators, about 56 or 28 minutes to fill from empty, and $7,000 against $9,000 with the included hanger.

The reservoir is 96 inches high and 57 inches wide laid flat, and about 36 inches deep when filled. The optional frame kit needs about 8 feet 6 inches of height, 6 feet of width and 3 feet of depth; for wall or ceiling mounting, the hanging points sit about 4½ feet apart. Each air separator is about 23.6 by 15 by 14.6 inches and needs at least 8 inches of open space around it.

The product page states no oxygen concentration for either air, and LiveO2 does not publish the reservoir volume, a weight for the Extreme, the noise, the power draw or which air separator ships with it. The warranty reads two ways: the product page says 2 years or 2,000 hours, or 4 years or 4,000 hours extended, while the warranty page gives air separators 2,190 hours and the extended plan 4,380 hours. That warranty excludes commercial use, although the product page recommends the Extreme for clinics; it links a Commercial Service Agreement for heavy-use commercial environments, which LiveO2 prices at approximately 8% of system price billed monthly, for North American customers only.

On returns, a like-new system sent back within 60 days is refunded less a 20% restocking fee, an opened system's refund is also adjusted for use hours, soil and missing items, and the buyer pays return shipping. Opened systems qualify only after New User Onboarding, and finance-vendor purchases, international orders and systems sold on a compassion-code or marketing-relationship discount are not eligible for a refund. LiveO2's marketing pages make broader claims than its intended-use statement, and we go by the intended-use statement.
