Oxygen Health Systems 36-inch 2.0 ATA Hard Shell review

The OHS 36-inch hard shell is the most complete hard chamber in our list. 2.5 mm 304 stainless steel, a sliding door, selectable pressure from 1.3 to 2.0 ATA and an all-in-one 95% oxygen system.

Oxygen Health Systems lists every safety piece we look for except an internal gauge, and gives three years of full warranty.

Price is the problem: $40,900 on the product page, and $48,900 on the brand's own chamber finder. Get the exact configuration in writing.

Best for: a full 2.0 ATA steel hard shell with the oxygen system and three-year warranty included.

The product page shows $40,900, marked down from $44,900. The brand's chamber finder lists the 36-inch at $48,900. That gap is likely configuration or timing, but it is the brand's job to explain it, so ask for a written quote. Financing is shown from $981 a month. Shipping is not stated on the page we read.

A steel chamber is furniture, not equipment. The system weighs 572 lbs, the shell is 36 inches wide and 88 inches long, and it comes with a soft mattress and pillow. Check that your floor, doorway and stairs can take it before ordering. In return you get a chamber that does not need zipping, stays rigid at any pressure and lets you set 1.3 to 2.0 ATA.

OHS lists an internal emergency release, interior and exterior emergency relief valves, an emergency alarm and interior and exterior pressure controls. That is a strong list for a chamber you can run alone. It does not mention an internal gauge on this page, so our table shows three of four.

$40,900 from the Oxygen Health Systems product page. Product page: $40,900, marked down from $44,900. The brand's own chamber finder lists the 36-inch at $48,900, so confirm the configuration before you pay.

Shipping: Not stated on the page we read.

Oxygen: All-in-one 95% oxygen system included (OHS).

Financing: Financing from $981 a month (OHS). Ask for the APR and the total repaid, not just the monthly figure.
