1.5 ATA Hyperbaric Chambers

QWhat is the difference between 1.5 ATA and 1.3 ATA?

1.3 ATA is 10 feet below sea level, the pressure used in most entry-level soft-shell chambers. At 1.3 ATA, you're breathing ambient air at mild elevation. 1.5 ATA is 16 feet below sea level, 50% above normal sea-level pressure. The dissolved oxygen in your blood plasma is meaningfully higher at 1.5 ATA, which is why most serious home HBOT users, athletes, and post-concussion protocols specify 1.5 ATA rather than 1.3 ATA.

QDo I need a prescription to buy a 1.5 ATA chamber?

Soft-shell 1.5 ATA chambers are generally sold for home and wellness use without a prescription requirement in most US states. The hard-shell HP1501 occupies a grey area, if you're buying it for clinical use, check with your state's medical device regulations. For home wellness use, Macy-Pan and OxyRevo soft-shell chambers do not typically require a prescription. Call 866-861-6317 and we'll walk you through what applies to your situation.

QWhat is the difference between a soft-shell and hard-shell chamber?

Soft-shell chambers are inflatable, they're portable, lighter, and easier to set up at home. They cap out at around 1.3 to 1.5 ATA. Hard-shell chambers are rigid steel or polycarbonate, they're more durable, hold higher pressures (up to 2.0 ATA), and are built for daily clinical use. In this collection, every chamber except the Macy-Pan HP1501 is soft-shell. If you need hard-shell at 2.0 ATA, see our 2.0 ATA hard shell collection.

QWhat is the difference between the OxyRevo Apex32 and Apex36?

Both reach 1.5 ATA and are soft-shell portable chambers. The Apex32 is 32" in diameter ($8,499), it fits most adults comfortably and works through standard doorways. The Apex36 is 36" in diameter ($8,999), it gives more shoulder and elbow room during sessions, which some users find more comfortable for 60 to 90 minute sessions. If you're between the two, go with the Apex36 for $500 more, the extra room is worth it for daily use.

QCan I use a 1.5 ATA chamber for post-surgical recovery?

Many people do. 1.5 ATA is a common pressure used for post-surgical recovery HBOT protocols. You should get clearance from your surgeon or treating physician before starting sessions, particularly in the early post-operative period. RecovAthlete can connect you with a telehealth provider familiar with HBOT protocols, ask on your consult call.

QHow much space do I need for a 1.5 ATA portable chamber?

The OxyRevo Apex32 needs roughly 7 to 8 feet of floor length and a ceiling clearance of about 3 feet when inflated. The Apex36 is similar but slightly wider. Most spare bedrooms, garages, or home gyms work fine. You'll also need space nearby for the oxygen concentrator and compressor, typically another 2 to 3 square feet. Send us your room dimensions on your consult call and we'll confirm fit before you order.

QIs 0% financing available on these chambers?

Yes. RecovAthlete offers 0% financing on qualifying purchases across all models. Call 866-861-6317 or book a consult to go through the numbers. Most buyers who commit to daily use find the monthly financing payment is less than what they'd pay for 4 to 5 clinic sessions per month.
