Inogen One G3 Replacement Columns (Sieve Beds) (Flow Settings 1-5)


It’s important to note that these replacement columns are for the High-Flow Inogen One G3 portable oxygen concentrator that offers pulse flow settings 1-5. These WILL NOT work with your Inogen One G3 that offers pulse flow settings 1-4.

In order to create medical grade oxygen, your Inogen One G3 relies on the sieve beds located in the replacement columns. You will have to regularly change your replacement columns to keep your G3 in working order.

Inogen recommends that you change your replacement columns every 18 months to 2 years, however, that is all dependent on the climate you live in, how often you use your concentrator, and if you store your concentrator properly.

What is Included With the Replacement Columns:

  • 2x Replacement Columns
  • 1 Tool to Unseat the Old Columns

Simple and Easy to Replace

Replacing your Inogen One G3 sieve beds is extremely simple. You don’t need any additional tools and it should only take you a couple of minutes. Here are step-by-step instructions on how to replace your sieve beds:

Step 1: Turn your Inogen One G3 off, disconnect it from any power supply, and remove the battery

Step 2: Flip your Inogen One G3 upside down so you can see the bottom of the machine

Step 3: Doing one side at a time, you will see two push tabs on the bottom of your concentrator. Slide one of the push tabs to release the sieve bed’s locking mechanism.

Step 4: As you slide the push tab out, take the unseating tool and slide it between the top of the sieve bed and your concentrator

Step 5: Use the unseating tool to pry the sieve bed free and slide it all the way out of your G3

Step 6: Repeat the steps above for the second replacement column sieve bed

Step 7: Insert your new replacement column sieve beds

The Importance of the Inogen One G3 Replacement Column Sieve Beds

The fact of the matter is, without functioning replacement column sieve beds your Inogen One G3 is a glorified paper weight. The sieve beds are located in the replacement columns and they are responsible for turning normal, ambient air into medical grade oxygen.

As you use your Inogen One G3, your sieve beds are constantly working to filter out impurities to provide you with the medical grade oxygen you need. But, the more you use your concentrator, the more wear and tear you put on your sieve beds. So, rather than requiring you to send your concentrator in for warranty repair, Inogen conveniently made the sieve beds a replaceable accessory!

Now, depending on how often you use your concentrator and your climate your sieve beds may last up to two years, or they may last about a year. It really all depends on your personal situation. To help you prevent any down time where you won’t be able to use your concentrator, your Inogen One G3 will notify you BEFORE you actually need sieve beds so you still have time to order your replacement columns.
