How to compare hyperbaric chambers
Before you compare shells, two things matter more than anything on the spec sheet: how much oxygen is actually available during a session, and how often you'll realistically use the chamber. Get those right and the chamber type mostly follows. Use the table above to sort every model on the specs that matter to you.
Pressure and capacity
Mild hyperbaric environments for home and wellness use typically run between 1.3 and 1.5 ATA, while higher-pressure hard-shell systems used in clinics go above that range.[1] Capacity and internal diameter affect comfort — a roomier chamber is easier to relax in for a daily session, while a single-person soft-shell is simpler to site at home.
Soft-shell vs hard-shell
Soft-shell chambers are lighter, more affordable, and plug into a standard outlet with minimal setup. Hard-shell chambers reach higher pressures and are common in clinical settings; rigid pressure vessels for human occupancy are built to the ASME PVHO-1 safety standard.[4][2] Neither is universally better — the right pick depends on your goals, budget, space, and how frequently you'll use it. For a deeper walk-through, see hard shell vs soft shell hyperbaric chamber or read about choosing a supplier, or explore hyperbaric chambers by state. Looking for the top of the pressure range?

Frequently asked questions
How do I choose the best hyperbaric chamber for home use?
Start with two questions that matter more than shell type: how much oxygen is available during a session, and how often you'll realistically use it. From there, weigh internal pressure (measured in ATA), capacity, internal diameter for comfort, and how easily the chamber fits your space. The comparison table above lets you sort every model side by side on those specs.
What's the difference between a soft-shell and hard-shell hyperbaric chamber?
Soft-shell chambers are typically lighter, more affordable, and easier to set up at home, operating at lower pressures. Hard-shell chambers reach higher pressures and are more common in clinical settings. Neither is universally better — the right choice depends on your goals, budget, space, and how frequently you plan to use it.
What pressure (ATA) do home and clinical chambers use?
Mild hyperbaric environments for home and wellness use typically run between 1.3 and 1.5 atmospheres absolute (ATA). Higher-pressure hard-shell systems used in clinical settings go above that range. The table shows the max pressure for each model so you can compare directly.
Can I rent a hyperbaric chamber instead of buying one?
Some models are available to rent as well as buy. Where rental is offered, the rental price is shown alongside the purchase price in the comparison table. Contact our team and we'll help you decide whether renting or owning fits your situation.
Do you sell hyperbaric chambers to clinics and businesses?
Yes. Metisine Health supplies equipment for home wellness users (B2C) and for clinics, studios, and gyms (B2B), often at different price points. Our team can help with model selection, NFPA 99 / AHJ compliance context, and installation for commercial settings.
