The Inogen One G3 sieve column pair restores your concentrator’s ability to produce high-purity oxygen. The G3 monitors purity continuously and shows an “O2 Service Soon” alert when the columns are due – replace the pair within 30 days of the alert. Which version do you need? Inogen produced two G3 column pairs that are NOT interchangeable: a pair for G3 units with flow settings 1–4, and a high-flow pair for G3 units with settings 1–5. Check the highest flow setting your machine adjusts to, or contact us with your serial number, and we will confirm the correct pair. Fitting: switch the machine off, remove the battery, press the latch release on the underside, slide the old column assembly out and slide the new pair in, then follow the sieve reset procedure in your G3 user manual. Compatible with: Inogen One G3 (correct version confirmed before dispatch). Not compatible with: Inogen One G4, G5 or Rove 6.
