Inogen One G5 Column Pair RP-502

It was exactly what I needed and completely plug & go.

I needed this part for my 02 concentrator. Came earlier than expected. Works like new!!!

excellent just what I needed

Easy replacement

The product was advertised to replace original filter inside portable oxygen concentrator. It fits right and easy to set up per instruction. Works great and I am satisfied with price. The seller packed it well and it was shipped on time for delivery.

This works as expected but I had to call tech support because they didn't sit properly. Turns out there are dust caps on both sides of the unit. Sometimes the dust caps get stuck inside and you have to pull them out by hand. The directions should state this.

perfect fit just as advertises good value fast shipping

Needed to buy a replacement for the original column in the Inogen G5 that my wife uses. This one works fine and it's a little bit (but not much) cheaper than going directly through Inogen even though it is their column but that's kind of typical with medical stuff. Easy to replace.
