Dreo HM409S Cool Mist Humidifier with RGB Night Light and Sleep Trainer: Ultra-quiet 28dB operation for peaceful sleep
For parents struggling with a baby's erratic sleep schedule, the DREO HM409S humidifier offers more than moisture. It acts as a sleep trainer, using soft light cues that dim gradually at night and brighten in the morning. This helps establish consistent bedtime routines, so your little one learns when it's time to rest. The ultra-quiet 28dB operation ensures the gentle hum won't wake a light sleeper, letting you adjust settings remotely via the app without entering the nursery.
Beyond the nursery, this humidifier maintains ideal 45–55% humidity across rooms up to 300 sq ft, protecting furniture and plants from dry air. Its 3L top-fill tank runs up to 30 hours, so you won't need to refill it overnight. Customize over 1,500 RGB night light colors for a calming glow during bedtime or a vibrant ambiance while relaxing. Easy cleaning with modular parts and optional anti-scale cartridges keeps maintenance simple.
