| portable oxygen concentrators
Hi,
Does anyone know what is the smallest, lightest portable oxygen concentrator available? The Inogen One and Invacare XPO2 seem to be the most popular. They are small but at around 7 lbs., they're not very light.
Then there are LifeChoice by Inovalabs and FreeStyle by AirSep which are under 5 lbs. each. I never heard of these before. Has anyone had any experience with these? Are there others as light as these?
Thanks,
Jerry
