How can we help?
How often should I change filters on my OxyGo or Inogen portable oxygen concentrator?
The OxyGo and Inogen portable oxygen concentrators have screen filters on the outside of the machine, they can be cleaned with a brush or washed with water. Only replace if missing or if the screen material is breaking down or damaged. There is also a filter on the output underneath the oxygen barb, this filter only needs to replaced as needed or between users.
