Who should buy which
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.
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.
Buyers who want the OxyHealth-equivalent spec at lower price, who don't need the OxyHealth brand premium, or who want a credible second-largest US manufacturer.
You want the largest installed base / dealer network (go OxyHealth) or you specifically need OxyHealth-only accessories.
