Frequently asked questions
No, the production of oxygen is limited to the capacity of its molecular sieve and is relative to the usage of the machine. Once the molecular sieve is consummed, it needs to be replaced in order for the machine to function optimally. For our home use machines, it can typically last for 1.5 to 2 years, while for portable machines, it averages around 1 to 1.5 years.
