The most common feedback we receive from customers is: "I love having a tankless oxygen machine, it gives me my freedom back and I love not having to worry if I am going to run out of oxygen." A portable concentrator can go anywhere with you and you will never run out (as long as you have a power source).

The ACHC dictates that to receive its accreditation a company must be represented as credible and reputable while being continuously dedicated to maintaining the highest level of quality and service.

Testing to acquire this accreditation is very rigorous and requires companies to be very transparent.
