In short

The oxygen engine of your G4

The RP-406 is the genuine Inogen One G4 column pair — the molecular-sieve beds that produce oxygen inside the concentrator. Replace them when oxygen purity drops or the G4 signals low oxygen despite clean filters, typically after several years of use. G4-only — it does not fit the G3, G5, or Rove models.

The sieve columns are where your concentrator actually produces oxygen. Over time the sieve material wears and purity drops — a fresh, genuine set restores oxygen output and clears low-oxygen warnings caused by tired columns.

✅ Inogen One G4 ❌ Not for the G3, G5, Rove 4, or Rove 6 (each uses a different column pair)

Restores oxygen purity

Fresh sieve beds bring output back to spec and clear the low-oxygen warnings caused by worn columns.

Genuine Inogen part

Made to the exact Inogen One G4 spec, so the sieve material and fit perform as designed.

Warranty by American Oxygen

Backed by American Oxygen — up to a one-year warranty on sieve beds. Ask us for the current term.

Details

What's included
One genuine Inogen One G4 column pair (two matched sieve beds). Filters, chargers, and other parts are sold separately.
Why genuine matters
Genuine columns use the correct molecular-sieve material and seat precisely, so oxygen purity comes back to spec and airflow isn't restricted. Off-brand or poorly matched columns can under-perform, wear faster, or keep the low-oxygen alarm on. Every set is backed by a warranty by American Oxygen — ask us for the current term.

Frequently asked questions

What are sieve columns (sieve beds)?
They're the molecular-sieve cartridges inside your concentrator that strip nitrogen out of the air and deliver concentrated oxygen. They're the most important wear part — when the sieve material tires, oxygen purity drops.
When should I replace them, and what are the warning signs?
There's no fixed schedule published by the manufacturer. Replace the columns when oxygen purity falls or the G4 shows a low-oxygen indicator that keeps returning after you've cleaned or replaced the filters — typically after several years of use, sooner with heavy daily use or dusty and pet environments.
Is this a DIY job or does it need a technician?
Replacing sieve columns is more involved than a filter change. Some owners replace the columns themselves; others prefer we handle it. If you're unsure, call us at (786) 755-8063 — we can walk you through it or service the unit for you.
Does it fit the G3, G5, or Rove models?
No. The RP-406 is G4-specific. The G3, G5, Rove 4, and Rove 6 each use their own column pair.
Is it genuine, and what warranty comes with it?
Yes — it's a genuine Inogen column set. It's backed by a warranty by American Oxygen (up to one year on sieve beds). Contact us for the current warranty term.
