Macy-Pan HP2202vsPerry Baromedical Sigma ICON 30

Higher pressure enables more clinical protocols. The Perry Baromedical Sigma ICON 30 reaches 3 ATA, which supports FDA-approved treatment protocols.

A ~23% price difference. At this range, the decision likely comes down to features and certifications rather than cost alone.

FDA clearance matters if you need insurance reimbursement, plan to operate a clinical facility, or want the highest safety assurance. For home wellness use, it's less critical.

This score reflects published studies, certifications, and clinical adoption. Higher scores indicate stronger evidence backing the manufacturer's claims.

Weight matters for portability and installation. Lighter chambers are easier to move between rooms or take to a second location.
