Zeolite filters for Inogen One G3

The filters or molecular zeolite sieve are the core part in the process of purification of the oxygen from the air: thanks to them the oxygen is separated from nitrogen and returned in pure form to oxygenate the lungs of the patient in therapy

How they work: Zeolite is a mineral known for some time. Thanks to its physical characteristics and its high porosity is able to retain the particles of a fluid according to the size of its molecules. In the case of oxygen concentrators the particles of nitrogen, larger than those of the oxygen, they are retained and trapped by the dense mesh of nanopores of the mineral. The intake air therefore becomes breathable oxygen thanks to the system of filtration and purification.

Duration: zeolite filters have a variable duration depending on the quality of the air we aspire and depending on the volume of daily use. On average, a pair of filters lasts about 18-24 months, but there aren't rare cases of intensive use of the concentrator (12-18 hours a day) that require a filter change after only 12-16 months.

Filters replacement: the owners of the concentrator Inogen One G3 can replace the filters in total autonomy by removing the old filters and reassembling the new ones. The operation can be done by removing the battery and pressing the appropriate release buttons, that are located on the lower base of the concentrator. The holders of the concentrator Inogen One G2 instead must necessarily send assistance in the device for the replacement of the molecular sieves by technicians: in fact, the filters are located within the chassis, and there is no possibility to replace them individually.
