In short

Keep dust out, keep therapy steady

The RP-301 is the genuine Inogen One G3 particle filter that traps dust, pollen, and airborne particles at the air intake to help protect the device. It is replaced approximately every 6 months, or per the manufacturer's maintenance schedule. G3-only.

This particle filter captures airborne debris at the intake so it doesn't reach the internal components, helping the G3 hold consistent oxygen purity.

Details

What's included

One genuine Inogen One G3 particle filter, sized to fit the air-intake slot.

Why genuine matters

A genuine filter matches the G3's intake exactly, so it seats correctly and filters without restricting airflow. A loose or wrong-size filter can leave gaps or choke the intake.

Frequently asked questions

How often should I replace it?

Approximately every 6 months, or sooner based on how much you use the device and how dusty your environment is.

Does it fit other Inogen models?

No. This particle filter is specific to the Inogen One G3.

Does the filter affect oxygen purity?

It helps the concentrator maintain purity by keeping dust and particles out of the intake. A clogged or missing filter can let debris reach the internals.
