A home chamber uses two machines: a compressor that fills it with air and, optionally, an oxygen concentrator that feeds concentrated oxygen to a mask inside. In our list, 8 of 14 chambers include a concentrator in the price (Skybaric, Oxygen Health Systems, OxyLife, The Recovery Outlet). OxyHealth and Newtowne sell one as a $1,550 to $1,575 extra, and Newtowne says its unit needs a prescription.
Two machines, two jobs
This trips up a lot of first-time buyers, so let us get it out of the way. A soft chamber is pressurized with ordinary room air by a compressor. That is what makes it a hyperbaric chamber. The oxygen concentrator is a separate box that pulls nitrogen out of room air and sends concentrated oxygen through a hose to a mask or cannula you wear inside.
The spec sheets show the split clearly. Skybaric lists a 15 L/min oxygen concentrator and a separate 180 L/min air compressor with the Pro. The Recovery Outlet's 34-inch hard shell has an integrated unit that does both, quoted at 10 LPM of oxygen and 70 LPM of air, with a built-in dehumidifier. OxyHealth ships its Vitaeris 320 with a 1/3 hp oil-less compressor and leaves oxygen as an option.
So when a price looks low, check which of the two machines it covers. Every chamber comes with the compressor. Not every chamber comes with oxygen.
Who includes one, who charges extra
We read each brand's product page (or its listed dealer) on November 11, 2026. Here is where the concentrator sits.
| Concentrator | Chambers | What the brand says |
|---|---|---|
| Included | Skybaric Go, Lounge, Pro | 10 L/min (Go, Lounge) or 15 L/min (Pro), oxygen by face mask |
| Included | OHS Oxy-Air 36, OHS 30-inch, OHS 36-inch | "FDA-Cleared food-grade 10 LPM Oxygen Generator integrated with this system at no additional cost" (Oxy-Air 36); all-in-one 95% oxygen system (hard shells) |
| Included | OxyLife MNS-2.0 | 10 to 15 LPM concentrator, mask and tubing |
| Included | Recovery Outlet 34D | Integrated, 95% or more oxygen, 10 LPM |
| Extra | Vitaeris 320, Respiro 270 | $1,550 option at Airpuria (10-liter DeVilbiss) |
| Extra | Newtowne A4-34 | Oxygen kit in the box; DeVilbiss 10-liter unit $1,575 with shipping, prescription required |
| Not listed | Grand Dive, Dive, OxyNova 7 | No concentrator in the features or price table (OxyNova mentions one at about 93% purity without saying it is in the price) |
Our scoring gives this a 10% weight: full marks when the concentrator is in the price, half when it is a priced option, and 2 out of 10 when the brand says nothing. The full rules are on how we score.
Flow rate and purity: reading the numbers
Two numbers describe a concentrator: how much it delivers (liters per minute, L/min or LPM) and how concentrated that oxygen is (a percentage).
Most chambers here sit at 10 L/min: the Skybaric Go and Lounge, the OHS Oxy-Air 36, The Recovery Outlet's hard shell, and the DeVilbiss units OxyHealth's dealer and Newtowne sell. The Skybaric Pro steps up to 15 L/min. OxyLife's packages run from 10 to 15 LPM, and the bigger concentrator is one of the things the $27,900 and $32,900 packages add over the $22,900 Essential.
On purity, OHS quotes a 95% oxygen system for its hard shells, The Recovery Outlet says 95% or more, and OxyNova mentions about 93%. Several brands do not publish a figure. If yours does not, ask for it in writing with the model number of the concentrator, then look that model up.
Which flow you need is not something a product page can tell you. Your doctor or the person prescribing the oxygen will.
Prescription and paperwork
Newtowne says plainly that its DeVilbiss 10-liter concentrator requires a prescription. Oxygen Health Systems calls the generator in its Oxy-Air 36 package "FDA-Cleared", which is a statement about that concentrator, not about the chamber: OHS does not state FDA clearance for the chamber itself, and we score it that way.
OxyHealth goes further on the chamber side and says a physician prescription is required to purchase its chambers at all. If you are buying a package with oxygen included, ask the seller what paperwork they need before they ship. It saves a week of back-and-forth after you have paid.
Oxygen and fire safety
This is the part we would not skip. In its August 25, 2025 letter on safe use of HBOT devices, the FDA says it is aware of recent reports of fires with HBOT devices that resulted in serious injuries and deaths, with the root cause not yet known. It asks users to "be aware that there is a heightened risk of fire with use of oxygen at a high concentration", to use proper grounding, and to follow the manufacturer's instructions on prohibited items such as electrical or static devices.
It also notes that some fabrics produce more static than others (wool and synthetics) and points to cotton clothing, according to the manufacturer's instructions. At home that means a few simple habits: no phone or heating pad in the chamber unless the maker says it is allowed, cotton clothes and bedding, and the concentrator placed where the maker tells you. Our home safety guide goes through the full list.
What oxygen adds to the bill
Put the concentrator in and the price ranking moves around:
- Newtowne A4-34: $5,795 + $1,575 = $7,370, shipping included.
- OHS Oxy-Air 36: $9,690, concentrator, compressor and dehumidifier included.
- Respiro 270: $9,900 + $1,550 = $11,450 at Airpuria.
- Skybaric Go: $11,999, concentrator and shipping included.
- Vitaeris 320: $19,900 + $1,550 = $21,450 at Airpuria.
The A4-34 stays the cheapest even with oxygen. But the Oxy-Air 36 and the Respiro 270 swap places once oxygen is counted, and the gap between the Respiro and the Skybaric Go shrinks to about $550, for 9 more inches of width and 1.5 ATA. That is why our comparison tool shows the oxygen line for every chamber.
Noise, heat and where it goes
Brands publish very little here. OxyLife states 45 dB for the MNS-2.0 system. OHS adds a dehumidifier to its Oxy-Air 36 package, and Skybaric sells an air cooler for $950 as an option on all three of its chambers, which tells you heat inside a closed fabric chamber is something owners ask about. OxyHealth ships a 10-foot hose, so the compressor can sit a little away from your head.
If noise matters (it does in a bedroom), ask for the decibel figure of both the compressor and the concentrator, and whether either can sit in another room with a longer hose. Then ask the brand, not a forum, whether that is allowed.
Nothing here is medical advice. A hyperbaric chamber is a medical device: talk to your doctor before you buy or use one, and follow the maker's instructions.
