Overview
A private, seated chamber sized for the home
Comfortable inside
A fixed upholstered seat, carpeted floor, interior lighting and its own air conditioning keep the cabin cool and calm. Large windows on the 1.5 ATA model let in light and keep you connected to the room.
Simple to run
An automatic pneumatic system manages pressure for you. Oxygen from the included concentrator is delivered by mask, and a two-way intercom connects you with the person outside.
Your colors
Your space. Your aesthetic. Your chamber.
Every CY3 is built to order, so the exterior shell and interior upholstery can be made in colors from standard RAL or Pantone charts. You choose your colors after you order, and we confirm them with you before production begins. The color charts are in the gallery above. Chat with us now for help choosing.

Safety & use
Before your first session
From OxyCheny's operating guidelines. This is general product guidance, not medical advice. Hyperbaric sessions aren't right for everyone, so check with your clinician before you begin.
Before you enter
- No phones, tablets, batteries or other electronics
- No lighters, matches, perfumes or other flammable items
- No sharp objects. Wear 100% cotton clothing.
During a session
- You may feel pressure in your ears during the first 10–15 minutes. Swallow or yawn to equalize.
- The system holds a steady pressure automatically
- At the end, it depressurizes slowly before the door opens. Never force the handle.
Care
- Daily: wipe the interior with a non-alcohol disinfectant and check the door seal
- Weekly: check the concentrator filters and clean the air intake
- Monthly: check the tubing and pressure relief valves. Replace the HEPA filters every 500 hours.
Pressure and oxygen can cause ear or sinus discomfort and other effects, and oxygen raises fire risk. Read the FDA's guidance on the safe use of hyperbaric devices.
Research
What the research explores
Most published trials used 2.0 ATA with 100% oxygen across 40–60 supervised sessions. Home chambers and protocols differ, so these findings don't automatically apply to home use.
Staying sharp with age
A randomized trial in adults over 64 reported improvements in attention and processing speed after a 60-session course. Read the study
Stamina and exercise capacity
Small controlled studies in older adults and in trained athletes aged 40–50 reported better aerobic measures under clinical protocols. Older adults · Athletes
Recovery between workouts
A small cyclist study at 1.3 ATA reported better performance in a follow-up effort. Overall, recovery research is mixed. Read the study

We confirm your delivery details when you order.
Returns

FAQ
Questions, answered
Should I choose 1.5 ATA or 2.0 ATA?
Both share the same footprint and features. The 2.0 ATA version reaches higher pressure and has a steel door with round viewing ports. The 1.5 ATA version has a large window and weighs about half as much. Your clinician can help you decide what suits your goals. Chat with us now to compare.
Can I choose my colors?
Yes. The exterior shell and interior upholstery can be made in any color from standard RAL or Pantone charts. You choose your colors after you place your order, and we confirm them with you before production begins. The color charts are in the product gallery. Chat with us now for help choosing.
Does it work with a standard U.S. outlet?
OxyCheny builds U.S. orders for standard 110 V / 60 Hz household power. Together, the concentrator and air conditioner draw about 1,510 W, roughly 12.6 A at 120 V. Consider having an electrician confirm the circuit.
Is oxygen included?
Yes. A 10 L/min oxygen concentrator is included, so there are no oxygen tanks to buy. Oxygen is delivered by mask while the chamber is pressurized with air.
Can I use it on my own?
The system is designed to be run by one person, and pressure is managed automatically. OxyCheny recommends that setup and the initial settings be handled from outside the chamber. The intercom lets you talk with someone outside during a session.
Will I feel closed in?
The 1.5 ATA version has a large window, and both versions have interior lighting and their own air conditioning. If small spaces concern you, compare the larger CY5 or CY6.
Is it loud?
The compressor makes a steady hum while it pressurizes, which is normal for hyperbaric systems. A low-noise exhaust valve keeps the session itself quiet. OxyCheny doesn't publish a decibel rating.
How long does delivery take?
About three months: roughly 45 days to build your chamber and about 45 days by sea. Delivery is door-to-door, with customs and duties handled for you.
What if something arrives damaged?
Photograph the packaging and chamber, then contact us within 48 hours of delivery. Chat with us now or email info@heavenlifewellness.com.
