Frequently Asked Questions

  • 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. However, in homes with pets or increased impurities in the air, filters should be checked/changed more frequently.
