HELiOS Plus Liquid Oxygen (Product ID # H300)

HELiOS Personal Plus Liquid Oxygen System

Developed by CAIRE Inc., the HELiOS Personal Plus Liquid Oxygen System stands just 10.5 inches tall and provides up to 10 hours of worry-free oxygen therapy -- no need to carry additional batteries or search for an AC power outlet. HELiOS Plus operates in continuous flow up to 6 LPM; it provides up to 4 LPM in demand flow -- making it the industry's smallest unit to do so. The low-pressure HELiOS Plus (22 PSI) can be refilled via the stationary HELiOS LOX Home Reservoir for Liquid Oxygen Therapy. Once refilled, Plus weighs just 3.6 pounds -- ideal for wearing via shoulder or belt strap.

Product Questions

How do I submit to Medicare for the 80% they cover. I also have co-insurance for the other 20% Covered. Approved for both.
Is there a source for the carry case, which is broken? Or should I contact my Oxygen supplier and just get a new complete unit?

Great Device for exercerising
Like the face that I can use for continuous flow when I exercise and pulse when I'm stationary. Just need to add a carrying bag, but the handle is very convenient.
  • Large capacity
  • Needs to include carrying bag
Great product
Have been using this model for over five year. I've dropped it a number of times, but it just keeps "ticking." Bought a second one to extend my endurance.
Nothing beats the Helios lightweight with long service time
The Helios liquid oxygen has a very low weight even when filled and yet last all day for me. Oxygen concentrators would run out of battery life way before the end of the day. I am a new convert to liquid oxygen and love the new freedom this offers me.
