The Device Kit - what’s included?

Exposure to altitude boosts athletic performance. Used at rest, each Altium i10 hypoxia training session mimics altitude, adapting your body by increasing oxygen flow to the muscles. This, coupled with your regular training programme, results in increased endurance, power and speed.

You can now enjoy marked improvements with every training session, allowing you to reach new levels in cycling performance.

The Altium i10 Device Kit has everything you need to get started. Containing the Altium i10 hypoxia device, oximeter, nose clip, four cartridges and carrying case, your portable, efficient and affordable altitude training regime starts here.

The Device in detail

Calibrated to your specific needs, the Altium i10 re-breather can simulate altitudes of up to 13,000ft (4,000m) without having to leave home. That’s equivalent to moving from sea level to the height of Mont Blanc in less than a minute. Unlike masks that simply deprive the body of oxygen, the Altium i10 safely reduces oxygen concentration with every breath. Over a course of one-hour sessions, oxygen concentration can be reduced by up to 12%, replicating the effects of altitude.

  • Replacement CO2 scrubber cartridges (5 pack)


Replacement cartridges

The Altium i10 replacement cartridge life span depends on your level of fitness, but on average each cartridge lasts for approximately two, one-hour training sessions.

Exhausted cartridges are easy to detect as you will no longer be able to drop your SPO2% into the hypoxic region (below 95%).

Cartridges come in handy packs of five, with discounts available when purchasing three packs or more.

The cartridges in close-up

The Altium i10 scrubber cartridges play a highly significant role when replicating altitude. Every time you breathe into the device, the small granules trap CO2 resulting in less carbon dioxide being re-inhaled. As you continue to breath through the device, that re-breathed air, sees oxygen levels continue to drop by up to 12%, convincing your body to adapt to lower oxygen availability as though training at high altitude. This results in the body having greater capacity for endurance, power and speed and allowing you to enjoy even greater cycling success.
