Larger interiorbudget pricing

Overview

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.
