Protocol
Mild hyperbaric chambers operate at 1.3–1.5 ATA using ambient air or enriched oxygen. They are soft-sided, portable, and widely used for wellness, athletic recovery, and anti-aging — typically at spas, gyms, and holistic health centers.
Mild hyperbaric oxygen therapy (mHBOT) uses flexible, soft-sided chambers pressurized to 1.3–1.5 ATA — lower than hard-shell medical chambers. Most mild chambers use ambient air (21% oxygen), with some using supplemental oxygen delivered through a mask to boost the effective concentration. Because they operate at lower pressures, they do not require the same medical-grade oxygen supply or engineering as hard chambers, making them practical for non-hospital settings. While they are not FDA-approved for clinical HBOT indications, mild chambers are popular in the wellness market for general recovery support, sleep quality, and anti-aging programs.
Quick facts
What happens during a session?
You enter the soft-sided chamber and zip it closed. A compressor gradually inflates it to 1.3–1.5 ATA. You can lie down, read, or use a phone during the 60-minute session. The slightly elevated pressure increases dissolved oxygen in your blood plasma. Some chambers allow you to breathe enriched oxygen through a mask for additional benefit. You emerge feeling refreshed — many users compare it to the effect of altitude acclimatization in reverse.

Common questions
Is mild HBOT the same as medical HBOT?
No. Medical (hard-shell) HBOT operates at 2.0–3.0 ATA with 100% oxygen — much higher than mild chambers. FDA-approved indications require medical-grade chambers. Mild chambers offer wellness benefits at lower pressure but are not a substitute for clinical HBOT.
Does insurance cover mild hyperbaric therapy?
Generally no — mild HBOT is considered wellness, not medical treatment. Medicare and most private insurers do not cover it. Expect to pay out-of-pocket.
Can I buy a mild hyperbaric chamber for home use?
Yes — portable mild chambers are available for purchase ($3,000–$15,000). However, professional guidance on protocols and safety is recommended. Many people prefer clinical sessions to ensure proper oversight.
What's the difference between a soft chamber and a hard chamber?
Hard chambers are rigid steel or acrylic vessels rated for 2.0–6.0 ATA with 100% oxygen. Soft chambers are flexible, pressurize to 1.3–1.5 ATA, and typically use air rather than pure oxygen. Hard chambers are required for FDA-approved medical treatment.
