Things To Know

3-Year or Lifetime Warranty?
You can order your Comfort with a lifetime or 3-year warranty. Batteries and sieve columns have a 1-year warranty and other accessories have a 90-day warranty.
Can I use the Comfort while sleeping?
All pulmonologists order a minimum of 1 to 2 continuous flow while sleeping. The CAIRE Comfort provides only pulse flow oxygen, which requires sufficient inhalation to trigger the pulse of oxygen. All oxygen users would be best served by using a portable unit that has a continuous flow setting while sleeping. We recommend the DISCOV-R Portable at 6.3 pounds - delivering 2 liters continuous flow and 8 pulse flow settings.
Can I use the Comfort without a battery?
Yes! The CAIRE Comfort can be used without a battery as long as it is plugged into a wall outlet with the AC power supply or a vehicle with the DC power supply.
Can I use the Comfort while charging?
Yes, the CAIRE Comfort can be used while it is plugged into an AC electrical outlet or a DC vehicle outlet. The external power will run the unit and charge the battery at the same time.
How long does it take to charge the batteries?
It takes about 3 hours to charge the CAIRE Comfort batteries.
What is the expected maintenance?
There is an air inlet filter that should be cleaned weekly. The G5 also has replaceable sieve columns that are warrantied for one year and will need replacing about every 15-18 months depending on use and climate.

The question of whether Medicare will cover the cost of a portable oxygen concentrator is one we receive frequently.

You may have been told by your homecare provider that Medicare does not cover portable oxygen concentrators or that they simply do not carry them.

You’ll rarely be given a full explanation, in part because it’s complicated. The answer is Yes and No.


No, Medicare will not purchase a portable oxygen concentrator. They provide only a monthly rental benefit for oxygen equipment.

No, Medicare will not cover a portable oxygen concentrator in addition to the oxygen tanks you most likely already receive. They don’t pay more money for more equipment.

Yes, your Medicare oxygen benefit covers the cost of oxygen. However, the portable oxygen benefit can be satisfied with larger gaseous tanks or a portable oxygen concentrator.

Note: Regardless of the equipment provided, Medicare pays the same amount (about $134 per month for 36 months = $4,800).

No, most homecare providers do not choose to provide a portable concentrator. Since they receive the same amount of reimbursement from Medicare for a portable concentrator as they would for an oxygen tank.

Note: Portable oxygen concentrators are more costly for an oxygen provider to provide.
