Important Safety Information

  • Always place the humidifier on a firm, flat, water-resistant surface away from walls and furniture.
  • Do not operate the humidifier without water in the tank.
  • Unplug the humidifier from the electrical outlet before filling, cleaning, or moving.
  • Keep out of reach of children.

Setup

  2. Choose a Location: Place the humidifier on a firm, level, water-resistant surface at least 12 inches (30 cm) away from walls. Avoid placing it on carpets, towels, or other absorbent surfaces that could block the air vents.

  3. Fill the Water Tank: Remove the water tank from the base. Unscrew the tank cap and fill the tank with cool, clean tap water. The wide tank opening allows for easy filling. Securely replace the tank cap.
