A hyperbaric chamber is a regulated medical device. The buying decision is not just price. It is class, indication, parts support, training, and the legal frame your operation will run inside.
This guide walks through that frame in plain language. It pulls model and clearance data from the FDA 510(k) database (2024).
Treat accreditation as a credibility signal, not a feature.
Hard-shell vs soft-shell — the decision that drives every other one
Hard-shell and soft-shell chambers are not two flavors of the same product. They are different devices with different clearances and different uses.
Hard-shell chambers are metal-walled and run at 1.5 to 3.0 ATA. They treat the 14 FDA-approved indications listed by Medicare (2024).
These are the chambers hospital wound centers use.
Soft-shell chambers are fabric-walled and run at 1.3 ATA. They carry FDA clearance for one indication only: acute mountain sickness. Any other use is off-label.
The clearance line matters because it sets your legal indications and what you can honestly tell patients. The FDA consumer warning (2021) is direct about this.
Off-label promotion has triggered warning letters.
What 510(k) clearance actually means
A 510(k) is the regulatory permission slip for a device to be sold in the US. It is not an efficacy endorsement.
It is a "substantially equivalent" finding against an earlier device.
The openFDA database (2024) lists 69 cleared hyperbaric chambers under product code CBF. Big names you will see:
- Sechrist Industries — K100268, K140559, K052713 (monoplace lines)
- Perry Baromedical — K990927, K072427 (Sigma monoplace), K983648 (multiplace)
- ETC Biomedical — multiplace clearances
- Healing Chambers International — multiplace and monoplace clearances
- Summit to Sea — K072757 (Dive and Shallow Dive)
- Newtowne Hyperbarics — soft chambers cleared for altitude sickness
For our complete cleared-chamber breakdown, see FDA-cleared hyperbaric chambers: the complete list.
Verify any chamber you consider against the FDA database before signing. The seller's claim is not enough.
New vs used: the math that actually matters
New chambers come with warranty, training, and current parts. Used chambers come with savings and homework.
For a new Sechrist monoplace, expect $150K to $250K plus install. For a Perry Sigma monoplace, the range is similar.
Used 5-year-old units cluster around $80K to $120K.
The catch is what the savings cost. Older hard chambers need NFPA 99 (2024) third-party inspection. Recertification can run $5K to $25K.
Used chambers past 15 years often need a new control system or fall outside manufacturer support entirely.

Monoplace vs multiplace: pick by patient flow
Monoplace chambers seat one patient. They are simpler to operate and dominate US wound centers.
Multiplace chambers seat multiple patients plus attendants. They allow direct medical care inside and run more flexible profiles. They cost $1M to $5M plus a custom build.
For most clinics, a monoplace makes sense. The patient flow only justifies multiplace if you treat acute indications like carbon monoxide poisoning or decompression sickness. See the decompression sickness evidence atlas for the full study-by-study evidence breakdown.
Multiplace chambers are also the standard at military and large academic centers.
Soft-shell choice points if you go that route
If you are buying a soft chamber, the brand options include several US makers and one major import. Each has different price points and warranty terms.
The Vitaeris 320 sits at $18K to $22K new and is the most established US soft model.
Summit to Sea's Dive and Shallow Dive lines run $10K to $14K. Newtowne Hyperbarics' Solace 210 runs $9K to $11K.

Be honest with patients about what 1.3 ATA delivers. Our Aviv Clinics evidence vs marketing review (2026) shows where the wellness category claims outrun the data.
UHMS accreditation matters for hospital and clinical work
The Undersea and Hyperbaric Medical Society directory (2024) accredits HBOT facilities, not chambers. 180 of the 1,588 US HBOT centers in our directory carry accreditation.
57 of those have the "with distinction" tier.
UHMS reviews chamber type, fire safety, operator training, and medical director oversight. The accreditation signals the program runs the FDA-approved indications under hospital-grade standards.
If you intend to bill insurance, accept Medicare patients, or treat the 14 FDA-approved conditions, plan for accreditation from the start. The buying decision then locks to Class II hard-shell chambers.
Operating costs over the chamber lifetime
Purchase price is roughly a quarter of the lifetime cost. Real ongoing costs:
- Maintenance: $5K to $30K per year for hard chambers; $500 to $2,500 for soft
- Parts: oxygen analyzers, regulators, hoses, gaskets — often $2K to $8K per year
- Insurance: malpractice plus property — $5K to $25K per year
- Operator training: CHT certification plus refreshers — $2K to $5K per operator
- Medical director: a hyperbaric-trained physician — $20K to $80K per year part-time
The numbers are real. Skipping any line item is what creates the safety gaps the clinic red flags guide tracks.
A reasonable first-year clinic budget runs $300K to $500K all in.
The buyer checklist that actually matters
Before signing anything, verify each item below:
- FDA 510(k) number matches the model on the database
- Indications for use in the clearance match what you intend to treat
- NFPA 99 third-party inspection records for any used hard chamber
- Manufacturer parts and service support is active for the model
- Operator training path includes CHT certification (2024)
- Medical director is hyperbaric-trained, not a marketing partner
- Liability insurance covers HBOT-specific indications
- State licensure rules match your intended scope of care
- Facility build meets NFPA 99 chapter 14 (2024) for oxygen-rich environments
The whole list runs to roughly 25 items in a full procurement document. Use this short list as the floor.

Frequently asked questions
Do I need FDA clearance to buy a chamber for personal use?
The chamber must have FDA 510(k) clearance to be sold in the US. Personal buyers can purchase a cleared soft chamber; the chamber's indication is acute mountain sickness, and other uses are off-label. Hard-shell clinical chambers can be sold to physician-owned facilities but are not sold to consumers.
What is the total first-year cost of opening an HBOT clinic?
A reasonable first-year budget for a single-chamber monoplace clinic runs $300K to $500K. That includes a $150K to $250K chamber, $20K to $50K facility build, $20K to $40K operator and director costs, $10K to $25K insurance and licensure, and $30K to $80K marketing and operations. UHMS accreditation adds $20K to $40K if pursued in year one.
Can I run a chamber without a physician on staff?
If you offer the 14 FDA-approved indications, a medical director is required for billing and accreditation. If you offer 1.3 ATA wellness sessions only, requirements vary by state. The legal exposure on off-label use without a director is significant; the FDA consumer warning lays out the position.
How long do chambers last?
A well-maintained hard-shell chamber can run 20 to 25 years. The Class II monoplace chambers from Sechrist and Perry have working units past 30 years in the field. Soft chambers typically need replacement at 7 to 10 years; zipper, seam, and pressure-relief valve wear drive that timeline.
Should I buy new or used?
New is the cleaner path for first-time buyers. Warranty, training, and current parts support are worth the markup. Used chambers can save 30 to 60% but require third-party inspection, regulatory verification, and a realistic parts and recertification budget. The break-even point depends on chamber age; anything past 15 years often costs more to bring current than to buy new.
