The SP-804 is Inogen’s genuine intake filter for the Inogen One G5 and Rove 6 — the same part fits both. Tool-free swap in under a minute; it protects the sieve beds, your concentrator’s most expensive part. Replace it about every 6 months. 1-pack (6 months) US$26 · 2-pack — a full year — US$48 · 3-pack US$70, ships free. Not the same as the washable particle filter.
The SP-804 Intake Filter Assembly Kit is a genuine replacement for the Inogen One G5 and Rove 6 portable oxygen concentrators. It’s the first line of defense for your unit: it traps dust and airborne particles before they reach the internal sieve beds, keeping airflow clean and the concentrator running efficiently and quietly.
✅ Fits Inogen Rove 6
❌ Not for G3 / G4 (different filter)
Why replacing it matters
The intake filter is a consumable — it does its job by getting dirty. As it loads up with dust, the concentrator has to pull harder to draw air: more noise, more strain on the compressor, and less efficient operation. Replacing it on schedule protects the most expensive part of your concentrator — the sieve bed columns.
This is the intake filter (SP-804): the internal assembly you replace about every 6 months, and the one that protects your sieve beds. It’s different from the external, washable particle filter you rinse weekly. Not sure which you need? Call us at (786) 755-8063 and we’ll confirm the right part for your unit.
