Inogen Output Filter Kit
The output filter prevents micro-particles from being inhaled by the oxygen user, and must always be in place while using the Inogen device. This kit includes two output filters as well as a wrench which can be used to access the output filter behind the removable cannula nozzle. The output filter is used across all Inogen devices so please make sure to select your concentrator to ensure the correct style is shipped to you. The RP-107 output filter kit is compatible with the Inogen at Home, Inogen G2, and Inogen G3. The RP-404 output filter kit is compatible with the Inogen G4 and Inogen G5.
Is Vital Care USA an authorized retailer?
Yes — 100% authorized. Vital Care USA only partners with fully authorized U.S. manufacturers and distributors. Every unit includes the full factory warranty and authentic U.S. serial numbers. Your purchase is always protected.
Are the oxygen concentrators brand new?
Every concentrator we ship is brand new in original factory-sealed packaging unless clearly stated otherwise. All standard accessories, manuals, and warranties are included.
You can also review our easy, customer-friendly return policy if you have questions about unopened items or eligibility.
Do I need a prescription to order?
Yes — U.S. law requires a valid prescription for most home and portable oxygen concentrators. After checkout, your doctor can fax or email it to us, or you can upload it directly.
You can also email your prescription directly to us at support@vitalcareusa.com.
Once we receive it, your order ships right away.
Vital Care USA is not a medical provider and cannot provide medical advice. We do not determine oxygen flow settings or therapy levels. Always consult your licensed healthcare provider before selecting a unit or changing your prescribed oxygen settings.
Does insurance or Medicare cover this?
Most online oxygen concentrator purchases are not covered by Medicare or private insurance when bought outright. This is because coverage is usually tied to local in-network rental programs.
Many customers still choose to buy privately because it gives them:
- Full ownership of their device
- No rental restrictions
- Freedom to travel, fly, or stay active without paperwork
What is the ordering process?
Most in-stock oxygen concentrators ship within 1–2 business days after we receive your prescription and verify the order. Tracking is sent automatically by email.
We also offer next-day delivery options on select models and locations — contact us if you need fast delivery.
