# Natchan Shop List I found a stain on the lid. I believe it was already stained when I purchased it. It is an unused item. With a large 4L tank, you don't need to refill it frequently, as one fill lasts for about a day. It humidifies well not only in the living room and bedroom but also in large rooms such as offices. The operating noise is only 25dB, quieter than a whisper, so you can use it without worrying about the sound when sleeping or reading, and it's stress-free. It also has a dry-run prevention function, and it automatically stops operating when the water runs out. The outlet does not get hot, so it is safe even if you have small children or pets. It also consumes little power, making it eco-friendly and long-lasting. 232
