What to avoid when using the AquaOasis® Cool Mist 2.2L Water Tank Humidifier

Here are a few things to avoid when using the AquaOasis® Cool Mist Humidifier to ensure its longevity and proper functioning:

What to Avoid When Using the AquaOasis® Humidifier

Using Essential Oils
- Do not pour essential oils straight into the tank, as they can damage the ultrasonic system and obstruct the mist outlet.
Distilled or Hard Water
- Refrain from using hard tap water or water rich in minerals, as it may cause buildup and reduce efficiency. Use distilled water for optimal results.
Overfilling the Tank
- Avoid overfilling the tank past the max line to prevent leaks and weak mist output.
Placing on Uneven Surfaces
- Avoid setting the humidifier on uneven or soft areas like carpet, as it may disrupt airflow and balance. Use a flat, sturdy surface instead.
Blocking the Mist Output
- Make sure the mist outlet remains unobstructed, with open space around the humidifier for optimal mist distribution.
Leaving Water in the Tank for Too Long
- Do not allow water to sit in the tank for too long, as this can cause bacteria or mold to develop. Empty and rinse it if unused.
Using Harsh Chemicals
- Avoid using harsh cleaners like bleach or ammonia. Use a mild vinegar and water solution to clean, to prevent damaging the humidifier.

By following these tips, you can extend the life and improve the function of your humidifier.

In conclusion, the AquaOasis® Cool Mist Humidifier is a quiet, easy-to-operate, and safe way to enhance air moisture. It features adjustable mist, a 360° nozzle, auto shut-off, and a 2.2L tank, making it ideal for bedrooms, nurseries, and medium-sized rooms—offering comfort, practicality, and reliable results.
