The Inogen One G4 Particle Filter (#RP-405) comes with one replacement filter.

Designed as an eco-friendly replacement, the Inogen One G4 Particle Filter keeps dust, pet hair, and all other air-borne contaminants away from your oxygen. Washable and reusable, these top-notch particle filters need to be washed and dried weekly (more often in extremely dusty environments) to keep your G4 System working properly. Inogen recommends replacing the filter if it becomes misshapen or when the screen is damaged.

Note: This product only ships to addresses in the US.
