6. Operation
Once installed, the TOTO TTHU9619 Deodorizer Air Filter operates automatically as part of your toilet's deodorizing system.

- Odor Persists: Ensure the filter is correctly seated in its compartment and the cover is securely closed. Verify that the toilet unit's power is on and the deodorizing function is enabled (if applicable to your model). If the issue persists, the filter may be faulty or the toilet's deodorizing mechanism may require service.
- Filter Does Not Fit: Double-check that you have the correct TTHU9619 filter for your specific TOTO toilet model. Refer to the compatibility list in Section 3.
