OxyRevo Apex28 Portable Soft Hyperbaric Chamber – 1.5 ATA, 90" × 28"

A slim 28-inch lie-down soft chamber with a full 90-inch interior

The Apex28 pairs a 28 in diameter with a full 90 in lie-down interior and runs at up to 1.5 ATA. It is a good fit for people who want a smaller-footprint chamber without giving up length: the package is sized for one adult or child and has seven large double-layered windows to keep the interior bright. The package lists an upgraded 110 L air compressor, a 10 L oxygen concentrator, a reinforced stainless-steel internal frame, a mattress with pillow and bolsters, an internal compressor remote and a power-failure safety alarm.

Best for: Home users who want a slimmer portable lying chamber with room for taller users.

What a session looks like

Lie down on the mattress, zip the chamber closed and start the air compressor. The chamber inflates to the pressure you set (about 1.2, 1.3, 1.4 or 1.5 ATA with the adjustable regulator) while oxygen is delivered through a mask or cannula, so you can rest, read or listen to music. A remote lets you operate the compressor from inside, and automatic quiet relief valves keep airflow steady. When the session ends, pressure is released gradually and you unzip and step out. Follow the manufacturer's manual for your own protocol.

Space, power and setup

Soft chambers pack down for storage and transport, so plan a flat area of floor at least as long as the chamber, room beside it for the compressor and concentrator, and a nearby grounded outlet. Keep the machines clear of flames, sparks and heat sources and follow the manufacturer's manual for placement. At a glance: working pressure up to 1.5 ATA; 90″ long × 28″ diameter; noise level 50 dB or less. Weight and power draw are not published for this package, so ask our team. Free shipping applies to the continental U.S. only.

Standard version: the machines are separate units (110 L air compressor and 10 L oxygen concentrator; ask our team whether an air cooler is included). Pro version: an all-in-one machine unit option; ask our team for its contents for this model.

Questions buyers ask

Can I start at a lower pressure?

Yes. An adjustable pressure regulator lets you set the chamber to about 1.2, 1.3, 1.4 or 1.5 ATA, so you can start low and step up to the 1.5 ATA maximum.

Do I need to buy oxygen cylinders?

No. The included 10 L oxygen concentrator makes oxygen from room air, so there is nothing to refill.

How is the Apex28 different from the Apex28 Mini?

Both have a 28 in diameter and run to 1.5 ATA. The Apex28 is 90 in long and the Mini is 78 in long.

Who fits inside?

The manufacturer's package describes comfortable space for one adult or child.
