Inogen One® G4® Intake Filter Assembly Kit
Keep your Inogen One G4 breathing clean with the official Intake Filter Assembly Kit. The intake stage is your concentrator’s first line of defense—capturing dust and common airborne particles before they reach internal components. Swapping the assembly at the right intervals helps protect the compressor and sieve beds, supports consistent oxygen purity, and reduces unnecessary service calls.
This G4-specific kit is easy to install (no tools required) and built for everyday use at home or on the go.

FAQs
1) Is the intake filter assembly washable?
No. The intake media is non-washable. Replace the assembly on schedule.
2) How often should I replace it?
Typically every 3 months. Replace sooner in dusty/pet environments or if visibly discolored.
3) Is this the same as the output filter under the cannula barb?
No. This is the intake filter assembly. The output filter (beneath the cannula barb) is a separate part replaced monthly.
4) Can I install it myself?
Yes—installation is tool-free and takes just a minute with the device powered off.
5) Will this work on the Inogen G5 or Rove 6?
No. It’s G4-specific. Use the intake parts made for your exact model.
