The pros should always outweigh the cons, but you should take them into consideration – the good as well as the bad – when you are shopping for an oxygen concentrator. Even the best models, or the one that is best for someone’s individual needs, won’t be 100% perfect. Knowing what to expect in the way of the “cons” will also help you prepare for these things down the line, and they won’t seem as bad if you already saw them coming.
Cons: Not a good varying flow setting (pulse dose only from 1 to 3), loudest portable oxygen concentrator (almost 50 decibels), short battery life for one battery (2 hours at highest setting).
Pros: Very small and lightweight (barely 5 lbs, only 9.5” high by 7.5” wide by a little over 3” deep), features sleep mode technology that adjusts the flow by your breathing patterns, FAA approved, can travel to an altitude of 10,000 feet outside of an airplane, available for rent.
