Difference Between Hard & Soft Hyperbaric Chambers

HBOT Soft Chamber vs Hard Chamber

Soft Hyperbaric Chamber

Soft hyperbaric chambers, also known as mild HBOT, portable, or inflatable chambers, are popular for their portability and ease of use. These chambers typically reach 1.4 atmospheres (ATA), which is the equivalent of being about 8 feet underwater. A soft shell chamber fills with 21-24% oxygen and the user wears an oxygen mask to breath 100% oxygen. A soft sided hyperbaric chamber is great for homes, gyms, spas, chiropractic offices, senior living communities, and wellness centers.

During mild HBOT in soft hyperbaric chambers, patients experience increased oxygen levels, improved blood flow, and reduced inflammation. The higher oxygen concentration allows for more efficient oxygen uptake by the lungs and better distribution throughout the body.


  • Affordable for home use
  • Minimal fire risk making it safe for home use
  • Users can bring small electronics inside chambers for entertainment
  • Portable and easy to set up
  • User friendly


  • Lower pressure compared to hard-sided chambers

Hard Shell Hyperbaric Chambers

Hard hyperbaric chambers offer the highest pressure levels for hyperbaric oxygen therapy (HBOT), making them an ideal choice for hospitals and medical facilities.  While these chambers can be used at home, their cost may be prohibitive for individual users.

Hard-shell chambers are steel-enclosed chambers that deliver 100% oxygen at atmospheric pressures above 2.0 ATA. The high pressure in hard hyperbaric chambers allows for efficient oxygen absorption and distribution, promoting cell rejuvenation and tissue healing.


  • Most research has been conducted in these chambers due to the ease of treating multiple patients at once
  • Offers maximum pressure levels for optimal oxygenation


  • Expensive for home use
  • Not portable
  • Due to 100% oxygen, users cannot bring electronics in the chamber for entertainment 
  • Assembly services highly recommended, increasing cost
