Who should buy which

Pick the OxyHealth Fortius 420 if

Family offices, couples wanting to share sessions, buyers building dedicated wellness rooms. The right tier for ultra-premium installs.

Skip if

You only need solo HBOT access (Vitaeris/Solace are sufficient), or you can't accommodate the 12×6 ft + ceiling footprint.

Pick the Sechrist 3600H Monoplace if

Clinics, private medical suites, and family offices building a true clinical-grade hyperbaric setup with trained operation. Also the right reference point for any buyer deciding whether the soft 1.3 ATA tier is sufficient.

Skip if

You are a home buyer wanting wellness HBOT. A soft-shell OxyHealth chamber is the correct tier and a fraction of the cost. Clinical hard-shell HBOT requires medical oversight, oxygen handling, and facility compliance.
