ROUNY Air Humidifier 4L Ultrasonic Features and Specifications
A 4L large capacity reservoir sets this humidifier apart from compact units that demand daily refilling, giving you up to 40 hours of runtime on a single fill at medium mist output. Ultrasonic technology vibrates water at high frequency to produce a fine cool mist without heating elements, which means whisper-quiet operation below 28 dB even at full power. The 360° rotating nozzle directs moisture to any corner of the room, eliminating the dry spots that single-direction units leave near windows or vents. Low water auto protection shuts the unit off the moment the tank empties, preventing motor wear and giving you genuine peace of mind overnight. BPA-free materials across every water-contact surface confirm that the mist your family breathes contains no harmful plasticisers, a standard ROUNY upholds across its entire home climate range — order online today at the official store for the best available price.

Very satisfied with the humidifier. First of all, I personally think it is very, very quiet. I don’t notice any operating noise at all. It only makes a bubbling sound sometimes when water enters the spray chamber. Pleasant, but at the same time utilitarian plastic. Very high performance in my opinion: the mist stream is voluminous and intense, to the point that the water tank empties in less than a day at maximum setting. The packaging was average, it arrived undamaged, but I liked that the float was secured separately to prevent damage. However, the box and bubble wrap were quite thin.
As I understand it, the light turns green when there is enough water all the time; I haven’t yet checked what will happen when the water runs out. Overall, it’s an excellent humidifier both in terms of price (I bought it for around 20 bucks) and quality, and most importantly, in terms of performance!
The direction of the steam jet can be adjusted using a knob on top, or you can remove the cover to get a vertical steam jet.

Quite fast shipping and delivery, nothing superfluous.
The packaging is, of course, quite wrinkled, but surprisingly the humidifier is intact. It’s very easy to use; just fill it with water, making sure to remove all the films and a piece of foam inside beforehand. It works quite quietly, with no water around or underneath, which is the most important thing.

Excellent, excellent humidifier for a very small price, fast delivery and dispatch of the order, works well, the only thing is that I would have liked it to be 6 liters instead of 4 liters.
