FAQs

1) How do I know when to replace the columns (SP-711)?
Your G4 will show a column replacement alert—many users replace annually under normal use.

2) Are RP-410 output filters shared with other models?
RP-410 is used across several Inogen models, but this kit is curated for G4. Always follow your device manual.

3) Can I wash the particle filters (RP-406)?
Yes. Wash monthly with mild soap and water, then air-dry fully. Replace at ~6 months or sooner if damaged.

4) Do I need the tool (RP-404) for output filters?
Yes. The RP-404 safely removes the barb to access and replace the RP-410 beneath it.

5) Will these parts fit a G5 or Rove 6?
No—this is G4-specific. See our maintenance kits for G5 and Rove 6.
