Clean air starts at the intake
The SP-507 is the genuine Inogen One G3 intake filter assembly, which traps dust at the air inlet before it reaches internal components. It is non-washable and replaced approximately every 3 months. It fits all G3 variants and is not the external particle screen or output filter.
This front-end module sits at the G3's air inlet and traps dust before it reaches the compressor, helping the device hold steady airflow and oxygen purity.
