Stored directory description. It is not a test we ran of this chamber.
The 501 is a larger soft-shell chamber from Oxygen Ark, providing more interior space than the 300-series models.
Who is this for?
The right starting point for first-time HBOT users, wellness beginners, and budget-conscious buyers who want to experience the benefits of hyperbaric therapy without overcommitting. The 501 gives you access to the core benefits of pressurized oxygen therapy — improved recovery, reduced inflammation, better sleep — at a price that makes personal use realistic. If you're new to HBOT and want to build a consistent habit before considering a higher-pressure upgrade, this is one of the most sensible places to begin.
Who it suits
501 is a soft-shell chamber, listed at 1.3 ATA, in the under $10,000 listed-price band, with a listed capacity of 1-person.

Who should skip it
- Listed maximum pressure is 1.3 ATA. HBOT Finder's chamber guide treats 2.0 ATA as the clinical standard, so this chamber is not for protocols that require 2.0 ATA or higher.
- Listed chamber type is soft-shell, so this is not a hard-shell clinical chamber.
- FDA clearance in our database is "no", so this is not an FDA-cleared device.
