Inogen One G5 Column Pair RP-502

This is by far the easiest way to order a Genuine Inogen One G5 Column Pair. The company that sends the product to you is the same company that Supplies the Mayo Clinic. When you combine that with the efficient way that Amazon sells and delivers products it can't be beat. If your Inogen needs serviced do yourself a favor and order here... By the way it comes with instructions and it can be changed with no tools in less than 5 minutes... The only thing you need to remember is to remove the 2 rubber protectors at the top of the columns before installing...

Worked perfect in the Inogen machine. Last about a year.

This was a lifesaver. My engine light was flashing, and I only had a couple of days left. Also, it was a lot cheaper than buying them from Inogen because I didn't have to pay for shipping

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.

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

This oxygen column is a perfect fit for the Inogen One G5 Oxygen machine. I had a lot of trouble figuring out how to install it, but that was simply because I did not notice the black rubber tips on the top ends of the column. They are hard to see because they are the same color as the column. If you install these into your machine those black rubber tips will end up in the machine and you will not be able to see them or even remove them since they will get stuck in the machine. I had to go to a local Oxygen machine repair place to have them removed, then they installed the column and everything worked perfectly. My suggestion to the company that manufactures these is to make those rubber tips a different color, such as orange or yellow. Then they would stand out and this issue would never affect your customers. I was lucky that the repair center did not charge me to remove those impossible to see rubber tips. The only way I was able to find out that those tips became stuck in the machine was because I found a YouTube video explaining this since other people apparently are also having the same problem. Please get this fixed thank you.
