Filters for Oxygen Concentrators

Your filter should be changed every 3 months to a year, depending on how often you use the unit, the model specifications, and according to the operation manual that came with your oxygen concentrator. The filters are all easy to access via a cabinet compartment. It's important to change the filters in your portable and home oxygen concentrators, according to the operation manual, to assure that you are always breathing only pure oxygen. We carry several types of filters for our in-stock portable oxygen concentrators, including gross particle filters, inlet filters, output filters, cabinet filters and HEPA filters.

We carry oxygen concentrator replacement filters for units that include the Inogen One Filters, CAIRE Filters, Invacare Filters and Philips Respironics Filters
