In depth
Everything about the G4/G5 Output Filter Kit
Small part, big job
The output filter is the last component oxygen passes through before reaching your cannula, catching any fine particles from the sieve process. A fresh filter keeps delivery clean and protects the cannula line — replace it about once a year, or as directed in your user manual.

Frequently asked questions
Is this the same as the particle (intake) filter?
No. The intake particle filter is the reusable mesh you rinse; this output filter sits at the cannula port and is replaced annually rather than cleaned.
