A stable system is not only the mist module. Tank, airflow, water level and control logic decide whether the mist can be used properly.
Keep the module under stable water depth and leave enough space above the water surface for mist collection.
Air should carry mist out of the tank without blowing directly onto the water surface. Too much airflow can reduce visible output.
Use humidity sensors and water level protection from the beginning. Adding them later often changes the tank design.
Project note: For OEM builds, confirm tank volume, outlet position, fan direction, water level control and service access before fixing the structure.
