FAQs

Some physiological responses begin within a few days. How quickly they appear depends heavily on how much exposure you accumulate — we recommend 8-11 hours per day in the altitude environment. Read more in How Many Hours in an Altitude Tent?

Individual responses vary considerably according to exposure and training status, which is why we avoid quoting a fixed number of weeks.

Yes, most rooms can be retrofitted to become an altitude room. The installation is usually simpler than expected. It involves sealing the internal door with rubber draft strips and introducing altitude air through ducting connected to an air conditioning diffuser or vent. Our system integrates seamlessly with recirculating air conditioning setups, ensuring the environment remains comfortable. We also monitor oxygen levels using a sensor to maintain your desired altitude consistently. To compare a room with a tent, read the guide to altitude tents and altitude rooms.

Both have their place, but sleeping at altitude is generally the more practical way to accumulate exposure.

• Sleeping at Altitude: Sleep gives a long, uninterrupted block of exposure that does not compete with training. Individual responses vary according to exposure and training status.

• Training at Altitude: Training at altitude reduces the pace or power you can sustain, because less oxygen is available. That can be useful in specific controlled sessions, but consistently compromising training quality can limit performance development.

This is why many athletes use the “live high, train low” approach. They sleep at simulated altitude and train closer to sea level, so key sessions keep their intensity.

Many athletic protocols use sleeping elevations around 2,000-2,500 metres (6,600-8,200 feet). The right altitude varies between individuals and goals. The altitude to oxygen chart shows the oxygen level at each altitude.

New users should begin conservatively — around 1,500 metres is a common starting point — and increase progressively while watching how they respond. Athletes with medical conditions, or concerns about oxygen exposure, should consult a qualified healthcare professional before beginning an altitude programme.

Some people notice mild effects at first, such as disrupted sleep, headaches or fatigue, especially if the altitude is raised too quickly. Lower the altitude if they persist. We recommend starting at a moderate altitude (1,500-2,000 meters) and increasing gradually. Read what to know before you start, and who should speak to a doctor first.

We don’t make weight-loss claims for altitude exposure.

Box Altitude systems are built for simulated altitude exposure and training, not body composition, and the evidence for altitude as a weight-loss intervention is not strong enough for us to stand behind. If weight management is your goal, that is a conversation for a qualified health professional alongside your training and nutrition.

The Box Altitude system uses an advanced oxygen sensor to constantly monitor the room’s oxygen concentration. The system adjusts the air flow to hold the altitude you set.

It is free for any purchase of our altitude systems. For oxygen sensors and HEPA air filter, see the products page on our website for the latest pricing information. For system prices, read the altitude tent price guide.

Box Altitude system hardware has a two-year warranty that covers any manufacturing defects and system performance issues. For additional peace of mind, we also offer ongoing maintenance and support services to ensure your system operates optimally.

• Sleep Cloud System: The Sleep Cloud system can usually be set up within 1 to 2 hours. The system is designed to be portable and easy to install without professional help. Once the tent is assembled and connected to the altitude generator, it’s ready for immediate use. For warm weather, read how to stay cool in an altitude tent.

• Altitude Room: An altitude room installation typically takes a full day, depending on the room size and complexity. The process involves sealing doors with rubber draft strips, connecting ducting, and integrating the altitude air system with an air conditioning diffuser or vent. A professional air conditioning or ventilation installer can handle this installation in a single day. Once completed, the system is calibrated to maintain your desired altitude level with continuous oxygen monitoring.
