1.5 ATA Sitting Hyperbaric Oxygen Chamber for Home

ATA stands for "atmospheres absolute" — a measure of pressure. At 1.5 ATA, the chamber runs at one and a half times normal sea-level pressure, which is a higher setting than the 1.3–1.4 ATA common to entry-level soft-shell chambers. Under that added pressure, oxygen is delivered through a facemask or nasal cannula.

Soft-shell chambers like this one use a flexible, heat-welded fabric capsule supported by an internal frame, so they're lighter, portable, and foldable. Hard-shell chambers use a rigid acrylic or steel structure and are typically ASME code compliant. This is a soft-shell chamber and is not ASME code compliant; it carries CE and ISO certifications, and its oxygen concentrator is FDA-approved.

The chamber pairs with an oil-free air compressor (120 LPM, 620W) that pressurizes the capsule and a DeVilbiss 10 LPM concentrator that supplies 95%+ oxygen through a mask or cannula. Total system power is roughly 1,460W on standard 110–120V household power (a 220V option is available).

On venting: the interior runs at around 40% oxygen and exhausts into the room at the same or a lower percentage than the original room air, so net room oxygen does not increase — no special firewall installation is required. A 5-stage carbon filter, a muffler, internal and external pressure gauges, and an emergency depressurization valve are all part of the system.

This is a one-person, sitting/reclining chamber with side J-style zipper entry and an adjustable lounge chair, designed for people who would rather not climb into or lie down in a top-entry capsule. Inflated, it measures about 92"L x 44.8"H x 42.5"W at the center, with a 72-inch zipper run.

It's used in home settings as well as therapy centers, chiropractic offices, wellness spas, and fitness facilities. Note that it is not specified as wheelchair-accessible — if step-free or wheelchair entry is a requirement, ask our team to confirm the right configuration before ordering.

That's a decision to make with a qualified physician, not from a product page. Hyperbaric oxygen therapy is generally used to support recovery, circulation, and overall wellness, but individual results vary and it is not a substitute for medical care.

People with certain conditions may have contraindications, so always consult your doctor before beginning any hyperbaric protocol.
