Details

What's included
One genuine Inogen At Home particle filter (RP-400).
Why genuine matters
The genuine RP-400 is shaped to fit the At Home housing exactly. An off-size filter can sit loose and let debris bypass it, or restrict the airflow the unit needs.

Frequently asked questions

Is it really washable?
Yes. Rinse it and let it dry completely before reinstalling. Reuse it until it shows wear, then replace it.

No. This filter is specific to the Inogen At Home stationary concentrator, not the G3, G4, G5, or Rove models.
Is it easy to install?
Yes. Removal and reinstallation are simple and require no tools.
