Ultrasonic humidifier Ruhhy 4 L with aromatherapy and ionization, includes 3 essential oils

Ruhhy Ultrasonic Humidifier 4 L combines a 4-liter water tank with ultrasonic mist generation, integrated aromatherapy and ionization functions. It produces a continuous cool mist without heating water, increasing indoor humidity to reduce dry air effects on skin, throat and plants. The device disperses fragrance from included essential oils and features user-friendly controls suitable for use in homes and offices.

Advantages

The ultrasonic technology ensures quiet operation and fine particulate mist that evaporates quickly without raising room temperature. A 4-liter reservoir provides extended runtime between refills. Built-in aromatherapy allows adding scent using the included essential oils, while the ionization function helps reduce airborne particles. Controls are simple to operate for varied mist intensity and intermittent modes.

Suitable for

• Living rooms and bedrooms to improve comfort and reduce dryness
• Home offices and workspaces to maintain stable indoor humidity
• Plant areas and conservatories to support humidity-dependent plants
• Use with essential oils for light fragrance distribution in medium-sized rooms

Key specifications

How to use

Fill the tank with clean tap or filtered water up to the indicated level, then securely place it on the base. Add a few drops of one of the supplied essential oils to the aromatherapy compartment according to personal preference. Select the desired mist intensity and operating mode using the control panel. The humidifier produces cool ultrasonic mist and will run until the water is depleted; automatic shut-off engages when the tank is empty. Clean the water tank and aromatherapy compartment regularly to prevent buildup.

Usage recommendations

Place the humidifier on a flat, water-resistant surface at least 20–30 cm from walls and electronics. Use distilled or demineralized water if mineral deposits are a concern. Replace water daily in environments with heavy use and clean the unit weekly. Use the included essential oils sparingly; avoid direct contact with surfaces and do not add oils directly to the water tank if the manufacturer’s instructions advise using the dedicated aroma compartment.
