- Reduced Airflow: Ensure the filter is installed correctly and not obstructed. A new filter should not significantly reduce airflow unless it is the wrong size or type for your unit.
- Persistent Odors: While the activated carbon layer helps with odors, if strong odors persist, check for other sources within the room or consult an HVAC professional for a deeper system cleaning.
- Filter Not Fitting: Double-check that you have the correct filter model (MAC-3000FT-E) for your specific Mitsubishi unit. Refer to the "Compatible Models" section.
- Unusual Noises: Ensure the filter is securely seated and not vibrating against any part of the unit.
For issues not resolved by these steps, please contact Mitsubishi customer support or a qualified HVAC technician.
