Who should skip it
- Listed maximum pressure is 1.5 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.
- FDA clearance in our database is "no", so this is not an FDA-cleared device.
- Listed portability is fixed-installation, so this is not a portable chamber.
- The low price estimate is $18,000, so this is not a chamber listed under $10,000.
- Listed tier is clinical-grade, so this is not an entry-level home wellness chamber.
