Weekly Cleaning:

- Clean Water Tank: Fill the water tank with a mixture of 1 teaspoon of white vinegar per gallon of water. Let it soak for 20 minutes. Use a soft brush or sponge to clean the inside surfaces, paying attention to any mineral deposits. Rinse thoroughly with clean water until the vinegar smell is gone.
- Clean Mist Nozzle: Wash the mist nozzle with warm, soapy water and rinse thoroughly.
- Clean Base: Gently wipe the base and ultrasonic transducer with a soft, damp cloth. Do not immerse the base in water.
- Reassemble: Allow all parts to air dry completely before reassembling the humidifier.
