Market

AMSR specializes in the sales and service of oxygen concentrators to patients for personal use.  An oxygen concentrator is a device that creates supplemental oxygen by concentrating oxygen available in the surrounding air. These devices are considered as safer, easy to use and inexpensive compared to compressed oxygen cylinders.  Portable oxygen concentrators are useful to people who require oxygen therapy that would otherwise require bulky oxygen tanks.   Advances in technology as well as an aging population support a growing market for portable oxygen concentrator systems.
