If my oxygen concentration is low, should I change the sieve beds?

Changing only the sieve beds may temporarily correct the problem, but there are generally underlying issues which result in the failure of sieve beds.
How often should I change my filters in my oxygen concentrator?

Maintaining clean filters is vital to the longevity of your compressor, sieve beds and oxygen concentrator as a whole. In most cases, following the recommendations of the manufacturer of your equipment is sufficient.
