4. Moving the Unit: Always unplug, then lift by the base, not the tank, to avoid spills.
5. Long-Term Use: For continuous use, refill daily and clean the unit weekly as per maintenance instructions.

Tip: Use distilled water to minimize mineral deposits and extend filter life, especially in areas with hard water.
