Smart Humidifier 311S 4L

The auto mode actually works—it kicked on when my room got too dry and shut off once it hit the target, which I've never seen from other units. Filling the 4L tank lasts me almost two full nights, and the mist is fine enough not to leave puddles.

I was a bit skeptical about the "advanced algorithm" claim, but after a week, the Auto Mode keeps my room at exactly 45% humidity without me touching a thing. The 4L tank is just the right size for my bedroom.

The 4L tank lasts almost two full nights before I have to refill it, which is way better than my old one. Auto mode actually keeps the bedroom around 45% without me touching anything. Waking up without a dry throat has been the best part.
