Disclosure and method.

How we make money

If you book a call and later buy a chamber, we may earn a commission from the seller, at no extra cost to you. That's the business. It's why we tell you plainly where a chamber's claims don't line up: an informed buyer is a better customer for everyone, including us.

How we audit a chamber

• We read the manufacturer's own product pages and record the date.
• We publish what the page states and mark anything missing as "not stated." We don't fill gaps from dealer listings.
• We quote marketing claims verbatim.
• We compare a manufacturer's pages against each other and flag contradictions.
• Brands we haven't verified yet are listed as pending, with no specs.

How we handle research

We link every study and describe only what it reports. Where we've only seen a study cited secondhand, we say so. We don't use the word "cure."

What this site is not

It isn't medical advice, and nobody here is your doctor. Hyperbaric oxygen therapy carries real risks. Talk with a licensed physician before starting. Audits reflect manufacturer pages on the date shown and can go out of date; confirm specs and FDA status with the seller before purchase.

Corrections

If a manufacturer believes we've misread a page, tell us on a call and we'll review it.
