Inogen Output Filters – 10 Pack (RP-410)

Protect the delivery side of your Inogen concentrator with the Inogen One G4 Output Filters – 10 Pack (RP-410). These tiny, critical filters sit directly under the cannula barb and catch fine particulates right before oxygen reaches your tubing—supporting consistent oxygen purity and reducing nuisance alarms.

Designed for easy, at-home maintenance, this 10-pack covers up to 10 months of routine replacements when changed monthly. Ideal for users and caregivers who want to keep therapy reliable with a simple, repeatable routine.

3. Pull the used RP-410 straight out; do not wash or reuse.

4. Insert a new RP-410 fully into the outlet port.

5. Re-seat the barb straight in until snug (hand pressure only).

6. Power on and confirm normal flow (no hissing or looseness).

FAQs

1) Are RP-410 filters washable or reusable?

No. They are single-use. Replace with a new filter each time.

2) Do I need the RP-404 tool?

It’s strongly recommended. The tool removes the barb safely without scratching the outlet.

3) Will these fit both G4 and G5?

Yes—RP-410 is used on Inogen One G4 & G5. Be sure you have the correct barb for your model.

4) How often should I replace the filter?

Monthly is standard. Replace sooner if you live with dust/pets or notice discoloration/restriction.

5) I hear a hiss at the outlet—what should I check?

Verify: (a) the RP-410 is fully seated, (b) the barb is snug and undamaged, and (c) your cannula is firmly attached. Replace worn parts.
