Dry indoor air can cause discomfort, reduce well-being, and negatively affect plants. Adler AD 7974 White is a modern ultrasonic humidifier designed to precisely maintain optimal humidity levels while adapting to your daily needs.

An advanced hygrostat keeps your chosen humidity within the 40–80% RH range with ±1% accuracy, while the clear LED display shows real-time readings. Ultrasonic technology creates a cool, fine mist with micro-sized particles, ensuring effective humidification with quiet operation.

The spacious 5.5-liter top-fill tank offers extended runtime and easy refilling. Additional modes, including plant care mode and night mode, allow the humidifier to fit seamlessly into different environments. A reliable and functional solution for healthier indoor air.

Precise Humidity Control – High-quality 40–80% RH hygrometer maintains the selected humidity with ±1% accuracy, continuously monitoring and displaying the current level.

Quiet Ultrasonic Technology – Breaks water into ultra-fine mist particles (1–5 μm) for efficient, even humidification without heating the air.

Large 5.5L Top-Fill Tank – Easy refilling from the top without disassembly ensures longer operation and fewer refills.

Modes Tailored to Your Needs – 3 mist intensity levels (100–250 ml/h), dedicated plant mode with strong mist output, and night mode with dimmed lights and minimal output.

Safety & Convenience – Automatic shut-off when water runs out and a built-in timer for automatic power-off after 2, 4, or 8 hours.
