In short

The oxygen engine of your Liberty2

The 800-1089 is the genuine O2 Concepts Oxlife Liberty2 sieve bed tube kit — one matched column pair with connecting tubing, the part that produces oxygen inside the concentrator. Replace it when oxygen purity drops or the Liberty2 signals low oxygen despite clean filters, typically after several years of use. Sold as one complete set.

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.

Details

What's included

One genuine Oxlife Liberty2 sieve bed tube kit — a matched column pair with the connecting tubing, sold as one complete set. Filters, batteries, 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.

What exactly comes in the kit?

One matched sieve bed column pair plus the connecting tubing that ties them into the Liberty2 — sold as a single complete set (1 set) so you have everything needed for the swap.

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 Liberty2 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. The kit comes as one complete set with the tubing; some owners install it 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.

Is it genuine, and what warranty comes with it?

Yes — it's a genuine O2 Concepts 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.
