Description and appearance
To maintain health, it is important to stay in an environment with normal air humidity. An air humidifier is essential for people suffering from asthma, allergies, respiratory diseases, and families with young children. The humidifier neutralizes the negative effects of household dust and improves a child’s sleep.
The H2O Humidifier, with a 300 ml water tank and spraying rate of 30–45 ml/h, can provide long-lasting humidification. It features two spraying modes – continuous and intermittent. In continuous mode, the device operates for up to 4 hours. In intermittent mode, it operates for up to 6 hours.

Preparing the humidifier for use
Before first use
Remove the lid of the water tank by turning it counterclockwise.
Take out the plastic tube (cartridge) with a foam insert from the inside of the lid. Soak the foam filter by immersing it completely in water.
Reassemble the set: place the spring into the cartridge first, followed by the foam filter.
Ensure that the upper end of the foam filter fits securely into the hole inside the lid of the humidifier. Fix the cartridge with the filter onto the inner side of the lid.
Before subsequent use
Open the top lid of the humidifier. Fill the tank with water up to the maximum level mark. Place the lid back on the water tank and secure it by turning clockwise.
Wait 10 minutes before using the device. Connect the power cable to the USB port of the humidifier. Plug the other end into a 5V adapter (not included), computer, laptop, or power bank.
Switch on the humidifier.

Never use detergents, gasoline, glass cleaner, furniture polish, paint thinner, or other solvents to clean any part of the humidifier.
Excessive humidity may cause condensation on windows and furniture. In this case, switch off the humidifier.
This device may be used by children aged 8 and above, or persons with reduced capabilities, only under supervision or after proper instruction. Children must not play with the device.
Do not operate the device with an empty tank, as this may cause damage.
Use clean tap or mineral water. Distilled water is not recommended as it may reduce performance.
