Optimize your state of mind

The first personal accessory to ensure air composition is right for optimal mental performance.

Fuel your brain

Compact and light, Altos was made to be carried around — put it on your keychain, attach to your backpack or simply keep it close to you.

  • Focus on your tasks

  • Science has proven that human cognition declines as CO2 levels in the air they breathe rise. So we created Altos to help you keep working at full capacity. Just place the device nearby so it can sample the air, and you’re ready to go.
  • Improve sleep quality

  • Research shows that sleep quality improves significantly when CO2 levels are lower, so Altos keeps working even while you’re asleep. Don't worry, it won't bother you with notifications – it collects air composition data throughout the night and advises you in the morning.
  • Get top results in sports

  • High CO2 levels hinder athletic performance and endurance, making your workouts less efficient and more dangerous. Take Altos to the gym or your home training – it will notify you if your body needs more oxygen to stay strong.

Companion app

A key aspect when designing Altos was that it could be with you wherever you go, so we created a companion app. You can set it to notify you when needed, or you can create a custom notification schedule.

Is air composition the air quality?

No, these indexes differ greatly. While the air quality is about the air pollutants that can be hazardous to your health in greater concentrations (excessive dust, smoke, gas leaks), the air composition shows how the air impacts your brain performance directly. Optimal air composition helps to improve your productivity.

How does it work?

Altos continually checks the CO2 concentrations in the air around you. The results are shown as the Brain Fuel levels indicating how good for your brain performance the air is.

How to test air composition?

You don’t need anything but Altos itself: just put it anywhere it can sample the air, and it will do the rest. You can check the Brain Fuel levels on its display or rely on push notifications – the app will let you know if the air composition changes.

How does CO2 affect my brain?

Higher CO2 levels impair not only our health but also our cognition: according to studies, when the CO2 concentration reaches 1000 ppm, people’s decision-making and strategic-thinking performance diminish significantly.
