In short

Genuine EverFlo columns for less

This is a Certified Pre-Owned column set for the Philips Respironics EverFlo home oxygen concentrator — the sieve beds that produce oxygen inside the unit. Each set is inspected and tested, then offered at a lower price than new. Replace the columns when oxygen purity drops or the EverFlo shows a low-oxygen indicator, typically after years of use. Up to a 1-year warranty by American Oxygen.

The sieve columns are where the EverFlo actually produces oxygen. This is a tested, Certified Pre-Owned set — a smart way to restore oxygen purity without paying full new price.

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.

Is this new or Certified Pre-Owned?

It's Certified Pre-Owned — a genuine Philips Respironics EverFlo column set that has been reconditioned, inspected, and tested. It's not new, but it's confirmed to perform and it's backed by a warranty by American Oxygen.

Which concentrator does it fit?

The Philips Respironics EverFlo home (stationary) oxygen concentrator. If you're not sure your unit is an EverFlo, send us a photo and we'll confirm.

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 EverFlo 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.

What warranty comes with it?

It's covered by up to a 1-year warranty by American Oxygen. Call us at (786) 755-8063 if you'd like the details before you buy.

Not sure this is the right part?

Send us a photo or call — we'll confirm the exact part for your unit.

El producto es de buena calidad, he comprado cinco con este último pedido sin embargo ya que no puedo comprar más de uno por el tema de pago de aduana que no puede llegar a $200 me gustaría ver si la empresa tiene cierta consideración y me hace algún descuento para poder seguir comprando aproximadamente 20 columnas más que me hacen falta
