The Inogen G3 Particle Filters are part of routine maintenance that should be done to the concentrator. To ensure proper air flow, the gross particle filters should be cleaned once every one or two weeks. Use warm soapy water to rinse them off. Ensure that the filters are dry before installing and turning on the concentrator. The gross particle filters should be replaced every six months. This pair of particle filters can only be used with the G3 with settings of 1-4 and not with the new G3 High Flow.
