Comparing Hyperbaric Chamber Manufacturers

Purchasing the Best Hyperbaric Chamber for You

At Hyperbaric Central, we help you find the right hyperbaric chamber—one that fits your goals, space, and budget. Our guide focuses on the American-built, FDA-approved chambers we sell, Newtowne Hyperbarics and Summit to Sea, as well as the risks of foreign-made chambers.

Beware of imported chambers from China marketed under U.S. brand names. These may claim to be “assembled in the U.S.A.,” but they lack the strict FDA oversight required for safety and durability.

Before you begin to compare chambers against one another here are some Very Important points

There are only 3 HYPERBARIC COMPANIES built in the US. And only these are monitored by the FDA for honesty, integrity and quality. If you buy from Asia or China, you won’t have the same thorough quality control. The Oxyhealth hyperbaric chambers consider themselves, ‘the Cadillac,’ because of their hefty price-tag. I will call them “Competitor” in this guide.

You can find out which brands FDA is reporting on for accidents or quality incidents. Note there is an FDA website called MAUDE that reports adverse event reports: accidents and incidents of chambers according to brand that is reported by owners for buyer awareness.

Chambers that are manufactured in China are flooding the markets under various US private-label names. These chambers state that they reach 1.5 ATA and higher. It is the “Wild west” of hyperbaric chambers, with none of these chambers vetted for safety. If the chamber isn’t a Newtowne, Summit-to-Sea or Oxyhealth brand name, it originates from China! If you are considering a China-built chamber, ask yourself these questions:

Where would I go, and whom would I go to if this company goes out of business?

How will I service a chamber from China after the 2-year warranty is up?

Who would I turn to for protection if the Chinese chamber has a serious mishap?

Clinics: Is there a burden of proof of safety by the FDA or else you will be deemed liable for equipment.

Who is the actual manufacturer of this company's chamber (the entity would be hidden by the private label brand-name)? And will that company help me if I find them?

Newtowne Hyperbarics, Summit-to-Sea and Oxyhealth are the only chambers built by Americans in the United States. And none of these companies rebrand with new identities!

Key Components to Consider

Compressors

The compressor is the motor that inflates your chamber. Summit to Sea and Newtowne Hyperbarics use medical-grade compressors with .003-micron filtration—which is more refined than OxyHealth’s .01-micron.

Both offer dual-compressor options for reliability, especially for clinical use, and they feature built-in safety release valves, helping prevent dangerous CO2 buildup in the event of failure.

Make sure to avoid “all-in-one” combo units from Chinese brands. While they claim to offer a compressor, oxygen concentrator, and dehumidifier in one unit, they offer less oxygen purity, more risk, and inefficient power management.

Summit began using 2 compressors because they feel that if one compressor shuts down the other will continue to work. Also a brand which doesn’t have an air release valve had an incident where a kid died inside, due to the chamber not deflating and so he breathed CO2. No one knew, so he passed away.

The idea is good, but the fact is, Newtowne and Summit both have release valves. So if the compressor did quit, the chamber would deflate. You would know there’s a problem. Summit does give an alarm free with purchase so you’d know too.

A second compressor is actually good if you’re running a clinic. It would make it less work for one compressor. Newtowne offers 2 as well or a larger compressor.

The All-In-One compressor-oxygen concentrator-dehumidifier combination, which comes with the Chinese brand chambers (and all of it private labeled USA and international brands), uses 3 electronics running together on one plug. This causes extra stress on the one shared plug, which potentially could incite extra heat generation on that plug. And with the complexity of using 3 different devices all managed by one engine, the result is your chamber will run inefficiently. Potential outcome of using one bloated device for 3 different purposes: carbon dioxide build-up in the chamber, lower than optimal pressure, a lower oxygen-output percentage (70%).

Oxygen Concentrators

Oxygen concentrators purify the air by removing nitrogen, delivering concentrated oxygen through a mask or nasal cannula.

When used alongside hyperbaric therapy, they can increase the oxygen absorbed into your blood plasma by up to four times—meaning one hour with a concentrator equals the benefits of four hours without.

We recommend the Drive DeVilbiss DS1021—a 10 LPM, 20 PSI medical-grade concentrator with a 3-year warranty. Commonly used in hospitals and clinics, it delivers reliable, high-concentration oxygen at one of the best values available.

This unit is fully compatible with most American-made HBOT chambers.

The Chinese brand chambers may give you just a 5 liter-per-minute concentrator when you purchase their chamber, unless you pay more to upgrade to their 10lpm unit. Of course, that will cost you extra. They may offer you an “All-in-One” system, which combines Oxygen Concentrator with Compressor and Dehumidifier. These have several problems because they run 3 separate operations at once on one powerline, all in one unit run inefficiently at all activities. One of the problems is that the oxygen concentrator runs at only 70 percent pure oxygen, not the 95 that you receive with a separate concentrator.

Finally, while Chinese brands build an accompanying concentrator that they bundle with their chambers, here in the USA, the manufacturers prefer to recommend actual medical equipment that are actually hospital devices. The concentrators are built for the medical industry. It might appear cheaper having the concentrator come with the chamber, but if you price out the combination with the chamber, you will conclude that the bundled price is very similar to the prices a-la-carte!

Free shipping for all chambers, despite the extra shipping charged by the manufacturer. Shoe and Long Shoe chambers. The 34″ & 40″ include a mattress in the price. All chambers include a 2 year warranty, which can be increased to up to 5 years.) Post-warranty repairs are very inexpensive due to Newtowne’s own factory.

Free shipping for all chambers, despite the extra shipping charged by the manufacturer. All chambers include a mattress. 2 year warranty that can be increased to up to 5 years.)

For a parent with a child, consider either the 33″ or 34″ sizes, best for space for the two of you. Two adults can fit inside, but it will be tight. 40″ best accommodates two grown adults, together.

How do you determine personal space inside the chamber? Split your coffee table and sofa by the number of inches of chamber you are considering (i.e. 34″). Then lie down between your coffee table and sofa to determine if the space feels good to you.

Newtowne and Summit to Sea are as much as 1/4 of the price of the competitor. You can purchase a superior-built 60″ easy-entry Walk-In style Summit to Sea Chamber for far less than the 32″ competitor’s. American made chambers are never shipped to you from China, thus, do not require 3-4 week delivery, nor permission for China to cover the warranty.

Chamber Durability Test

“The Cadillac” brand pressure-tests the strength of their chambers by pressurizing them up to 11psi. However, both Summit to Sea and Newtowne test their chambers at close to double the pressure, giving you far more assurance of their chambers’ strength and durability. Therefore, you can be assured the Newtowne and Summit chambers will not wear out or tear at the seams.

Zippers

The zipper closure on “Competitor” chambers utilizes 2 zippers with a urethane panel with a ‘flap’ to hold the zippers. That panel will, potentially, stretch with use and this stretching may cause you to have to manipulate the zipper to adjust it from the wear.

Newtowne Hyperbaric chambers are manufactured with 3 zippers that are held in place with a seam. So there’s no manipulating the zipper as the chamber ages. Many people like Newtowne because they use 3-ply urethane rather than 2, which makes Newtowne very durable. Newtowne uses a Superior zipper that won’t require waxing and the zippers are exceptionally durable. Newtowne’s Superior zippers withstand the pressure of the chamber and prevent the pressure from impacting the material.

Other people prefer Summit to Sea’s 2-zipper format because of the ease of closure. There is no need to maneuver to shut 3 zippers. Instead, you shut 4 car buckles on the outside, then zip yourself in. The Summit to Sea chamber has a simplified-closure 2-zipper, stable system protocol that also implements a set of 4 buckles. This zipper protocol makes getting in and out easy to do. This set up won’t stretch and won’t require future manipulation. Some people like the ease of Summit’s 2 zipper-buckle system. Summit chambers are built not to cave in above you if you get in from the side.

Newtowne is easier to zip from if set up with their opening at the top. Newtowne gives you a side option and a top option to enter. Summit only opens from the side.

If ever your zippers need any repair, keep in mind Newtowne is the only company that will repair your zippers with the same machines they built your chamber with. The other brands use alternative methods. This means they won’t end up in the same like-new condition.

Durability & Safety

If you’re going to invest in a hyperbaric chamber, it needs to be built to last—and with safety in mind.

Summit to Sea and Newtowne Hyperbarics pressure test their chambers at nearly double OxyHealth’s levels, ensuring long-term strength and seam durability.
Newtowne Hyperbarics uses 3-ply urethane and a triple-zipper system with top or side entry. They’re also the only brand that repairs zippers using the same machinery used in original manufacturing, restoring them to like-new condition.
Summit to Sea features a 2-zipper system with four external buckles, offering easier entry and exit.
Foreign-made chambers often lack consistent quality control and are rarely pressure-tested to the same standards, increasing the risk of zipper failure, seam rupture, and inconsistent performance..

Which Chamber is Right For You?

I’m looking for a Budget-Friendly Option.

The Newtowne 27″ and Summit to Sea Shallow Dive are cost-effective choices for individual users seeking basic features.

What are my Mid-Range Choices?

The Newtowne 34″ and Summit to Sea Dive offer more space and comfort for users desiring additional room. The Newtowne Shoe and Long Shoe offer you extra headspace for sitting up and lying down – both at very reasonable prices.

I prefer sitting in a Vertical Chamber.

The Newtowne Tent, Summit to Sea Dive Vertical, Summit to Sea Grand Dive Vertical, and Summit to Sea Grand Dive Pro Plus are suitable for users preferring to sit during therapy sessions. These chambers are easy to enter, for those with low mobility, while the Grand Dive Pro Plus is the largest Wheelchair Hyperbaric Chamber on the market.

 If you like the idea of sitting up on the floor, The Newtowne Shoe and Long Shoe offer you extra headspace for sitting up and lying down – both at very reasonable prices.

I need a Grand Size Chamber with space for two.

The Newtowne 40″, Summit to Sea Grand Dive, Summit to Sea Grand Dive Pro, and Summit to Sea Grand Dive Pro Plus provide ample space for multiple users or for users who wish to exercise during sessions.

Wheelchair Accessibility is a must for me.

The Summit to Sea Grand Dive Pro Plus Short and Summit to Sea Grand Dive Pro Plus Long are designed for users requiring wheelchair access, Both chambers offer the most spacious interiors on the market and can accommodate more than one person.

The Newtowne Hyperbarics Chambers

Warranty is 2 years. The “Competitor” had been 1 year but in 2018 raised their prices to build in a 5 year warranty. From the words of previous Competitor customers, the Competitor actually limits the number of repairs before refusing to repair their product.

Both Newtowne and Summit to Sea offer the 5 year warranty but it is optional rather than building the price over the extra warranty (because the chambers rarely require repair). One thing to note is the “Competitor” will not warranty or support a ‘used chamber’.

Lengths of each Newtowne chamber are sized longer for extra space. Lengths are: 91″ for the 27″, 95″ for the 34″ and 105″ for the 40″.

Any future repair through Newtowne is uncostly due to benefit of their inhouse factory, and finished in “brand new” condition since the chamber is repaired in-house. The wait-time is minimal, whereas if you have a repair with the “Competitor” chamber, there will likely be a long wait (up to 4 months). They repair at a separate independent facility.

You receive a steel frame, not PVC, so it won’t warp over time. The frame is outside the chamber for extra interior space.

You get 3-ply urethane vs 2-ply, so less stretch potential and less wear and tear on the seams over time.

Their 3-zipper style is specially designed to actually strengthen the chamber against the pressure to prevent wear and tear.

All Newtowne chambers except the 27″-style include an extra second auxiliary valve for a second oxygen concentrator.

Newtowne 34″, 40″ include mattress upgrades as part of the price. Their Tent includes a Free chair (recliner can be purchased inexpensively on Amazon) The reclinable mattress is extra with the Shoe and Long Shoe styles. Shipping is always free for 34″ and 40″ chambers.

Newtowne has never, ever been reported in the MAUDE accident and incident report.

The greatest benefit is the window is a heavier acrylic that doesn’t bubble out. Undue pressure inside a bubbled-out window ultimately wears out seams causing ruptures, tears and worn-out seams. Since the “Competitor” has often experienced tears in the seam, repair costs run between $1k and $4k, and because it’s repaired out of house, there is a month or more wait time, and they will only repair their chamber one time.

Newtowne offers 2 valve ports on their 34″ chamber for a second oxygen concentrator, compared to 1 valve port on Summit’s 33″ Dive.

Newtowne includes an alarm that goes off if the compressor quits for safety.

Newtowne now includes a gauge so that you can see the pressure while inside the chamber.

Summit To Sea

Summit uses a bright white material for a low claustrophobic feel.

Summit is the only brand to include a free cushioned mattress with the small size 26″ chamber as part of the price (along with all other size Summit chambers). Newtowne’s economy 27″ does not include this mattress — it would be a $275 add-on if desired (all other Newtowne sizes include the mattress).

Many people like the clean white appearance and the way light can penetrate because it is semi-translucent. The chamber is brighter inside.

Summit includes an inside gauge so you can see the pressure while inside the chamber. Summit is the only brand to include a free inside gauge with the small 26″ chamber as part of the price. It’s an add-on with Newtowne’s 27″ only; all other Newtownes include the gauge.

Summit has developed an exclusive structural design which makes their chamber lightweight along the top. This unique construction allows the weight of your chamber to not collapse upon you when you enter and exit, making it simple to close without fighting against your chamber shell’s weight.

Summit offers 2 compressors/motors standard. Newtowne offers the second as an upgraded option for an upgraded price.

All the chambers are 90″ long.

Summit to Sea is an international brand — they sell chambers worldwide. Newtowne is USA only.

Both Summit and Newtowne are privately owned. If there is ever any problem, you deal with kind, grass-roots owners who care about their brands, not unknown customer service reps.

Summit to Sea is the only hyperbaric brand to have available an exclusive air-conditioner-styled air cooler! This cooler lowers air temperature to 5 degrees below the outside room air temperature.

“Ocean Bottom Experience”: shine a color-shifting light along the chamber (with emphasis on blue light) and the white shell changes color, which will be experienced on the inside as being on the bottom of the sea.
