Buying Guide
Hyperbaric Chamber Buying Guide
Choosing a hyperbaric chamber requires evaluating pressure ratings, safety certifications, build quality, and manufacturer reputation. The right chamber depends on whether you need a portable unit for home wellness or a clinical hard-shell model for medical protocols. This guide covers everything you need to make an informed decision.
From OxyHealth, the global leader in hyperbaric chamber manufacturing with over two decades of experience and the industry's best safety record.
A hyperbaric chamber is a pressurized enclosure that allows a person to breathe oxygen at levels higher than normal atmospheric pressure. Chambers range from portable soft-shell units for home wellness use (1.3 ATA) to clinical hard-shell models for medical treatment protocols (up to 4.0 ATA). All OxyHealth chambers are FDA 510(k) cleared, ASME PVHO-1 certified, ISO 13485 certified, and UL certified.
Understanding Your Options
Portable vs Clinical Hyperbaric Chambers
Hyperbaric chambers fall into two main categories: portable soft-shell chambers operating at 1.3 ATA for home and wellness use, and clinical hard-shell chambers reaching up to 4.0 ATA for medical treatment protocols. Your choice depends on intended use, pressure requirements, and where the chamber will be located.
Soft-Shell Portable Chambers
- Operates at 1.3 ATA
- Designed for home and wellness use

- Designed for hospitals and clinics
- Robust steel construction
- Higher-pressure medical protocols
- 42" interior diameter
- Required for certain treatment protocols
OxyHealth clinical models: Fortius 420, Fortius 420 EXP
Key Buying Factors
What to Look for in a Hyperbaric Chamber
Pressure Rating
Portable chambers operate at 1.3 ATA, suitable for home wellness and recovery protocols. Clinical hard-shell chambers reach 2.0 to 4.0 ATA, required for higher-pressure medical treatments. Choose based on your treatment needs and clinical protocols.
Safety Certifications
The four essential certifications are FDA 510(k) clearance, ASME PVHO-1 for pressure vessel safety, ISO 13485 for quality management, and UL for electrical safety. OxyHealth is the only portable hyperbaric chamber manufacturer that holds all four certifications.
Build Quality and Materials
Medical-grade materials make a significant difference in durability, safety, and comfort. Look for chambers with reinforced seams, high-quality zippers, and comfortable interiors. OxyHealth chambers feature an organic cotton mattress and medical-grade construction throughout.
Compressor Quality
The compressor is the heart of any hyperbaric chamber. Purpose-built compressors designed specifically for hyperbaric use deliver consistent pressure, quieter operation, and longer service life compared to generic off-the-shelf compressors used by some manufacturers.
Warranty and Support
Ongoing support matters as much as the initial purchase. OxyHealth assigns a dedicated representative to every customer, providing personalized support for the life of your chamber. Ask any manufacturer about their warranty terms and post-purchase service model.
Interior Dimensions
Comfort during treatments is essential for consistent use. OxyHealth chambers range from 27 inches (Respiro 270) to 42 inches (Fortius 420) in interior diameter. Consider who will be using the chamber and how much space they need for a comfortable 60 to 90 minute session.
Critical Distinction
FDA Cleared vs FDA Registered
Understanding the difference between FDA 510(k) clearance and FDA registration is one of the most important factors when purchasing a hyperbaric chamber. These terms are often confused, but they represent very different levels of regulatory review and consumer protection.
FDA 510(k)-Cleared
- Device has been evaluated by the FDA for safety and efficacy
- Requires substantial evidence of equivalence to a legally marketed device
- Manufacturer must demonstrate the device meets safety standards
- Required before the device can be legally marketed in the U.S.
- All OxyHealth chambers are FDA 510(k)-cleared
FDA Registered Only
- Company has only notified the FDA that it exists
- No review of the device for safety or efficacy
- Does not mean the device is approved or cleared
- Any company can register by filling out a form
- Not equivalent to clearance in any way
Always ask for the FDA 510(k) clearance letter and ASME PVHO-1 GR-1 form.
These documents are the proof that a chamber has been properly evaluated and certified. If a manufacturer cannot provide them, proceed with caution. Learn more on our FDA documentation page and safety certifications page.

Why FDA 510(k) Clearance Matters When Buying a Hyperbaric Chamber
FDA 510(k) clearance means the FDA has evaluated a device and determined it is safe and effective. FDA registration simply means a manufacturer has notified the FDA that they exist. These are not the same thing. OxyHealth chambers are FDA 510(k)-cleared as Class II medical devices, not just registered. Many third-party resellers sell chambers that are only FDA registered, which provides no assurance of safety or efficacy.
Before purchasing any hyperbaric chamber, always ask the manufacturer for their FDA 510(k) clearance letter and ASME PVHO-1 GR-1 form with serial number. If a seller cannot provide these documents, that is a significant red flag.

Hyperbaric Chamber Buying FAQ
What is the best hyperbaric chamber for home use?
The Vitaeris 320 is widely regarded as the gold standard for home hyperbaric chambers, offering a spacious 32-inch interior, whisper-quiet operation, and the highest safety certifications. For users who need a more compact option, the Respiro 270 provides the same quality and certifications in a smaller 27-inch footprint. Both are FDA 510(k)-cleared, ASME PVHO-1 certified, and designed for daily home use.
Do I need a prescription for a home hyperbaric chamber?
Yes, hyperbaric chambers are classified as FDA Class II medical devices, which means a prescription from a licensed healthcare provider is required for purchase. OxyHealth can help connect you with physicians familiar with hyperbaric oxygen therapy to obtain a prescription.
How long do hyperbaric chambers last?
A high-quality hyperbaric chamber built with medical-grade materials typically lasts 12 to 15 years or more with proper care and maintenance. Many OxyHealth chambers have been in continuous operation for over 20 years. Regular maintenance and following the manufacturer guidelines will help maximize the lifespan of your investment.
What certifications should a hyperbaric chamber have?
A properly certified hyperbaric chamber should hold four key certifications: FDA 510(k) clearance (not just registration), ASME PVHO-1 for pressure vessel safety, ISO 13485 for quality management, and UL certification for electrical safety. OxyHealth is the only portable hyperbaric chamber manufacturer that holds all four of these certifications.
What is the difference between FDA cleared and FDA registered?
FDA 510(k) clearance means the device has been reviewed and evaluated by the FDA for safety and efficacy before it can be legally marketed. FDA registration simply means a company has notified the FDA that it exists and manufactures medical devices. Registration does not involve any review of the product. Always ask for the FDA 510(k) clearance letter before purchasing any hyperbaric chamber.
Can I finance a hyperbaric chamber?
Yes, OxyHealth offers financing through Brickhouse Capital with flexible monthly payment plans. Terms range from 24 to 60 months with up to 100% financing available. Fast approvals are available for both clinical and home users.
What size hyperbaric chamber do I need?
The right size depends on your use case. For clinical settings where patients of all sizes need comfortable treatment, the Fortius 420 offers a spacious 42-inch interior. For home use, the Vitaeris 320 provides a roomy 32-inch interior that fits most adults comfortably. If space is limited or the chamber is for a single smaller user, the compact Respiro 270 with its 27-inch interior is an excellent choice.
Is hyperbaric oxygen therapy safe?
Yes, hyperbaric oxygen therapy is considered very safe when using properly certified equipment. OxyHealth has the best safety record in the industry with over two decades of manufacturing experience. To ensure safety, always choose a chamber with FDA 510(k) clearance, ASME PVHO-1 certification, and follow the manufacturer operating guidelines. OxyHealth chambers include multiple redundant safety systems and mechanical overrides.
