Prices between HBOT chambers differ for a variety of reasons: brand, model, capacity for height and weight, the amount of absolute atmosphere supported (ATA), features, and details of assembly.
Much like the process of purchasing a car, the decision to purchase a HBOT chamber is one made by considering the needs and preferences of the user. Not all HBOT chambers are created equal, and taking the time to understand the distinguishing features between similar models will help the customer decide which brand and model will best meet their needs.
