Who should buy which
Family offices, couples wanting to share sessions, buyers building dedicated wellness rooms. The right tier for ultra-premium installs.
You only need solo HBOT access (Vitaeris/Solace are sufficient), or you can't accommodate the 12×6 ft + ceiling footprint.
Buyers who want the OxyHealth-equivalent spec at lower price, who don't need the OxyHealth brand premium, or who specifically want the longer 7-year warranty.
You want the largest installed base / dealer network (go OxyHealth) or you specifically need OxyHealth-only accessories.
