Inhouse product
I previously used 2 Pro model humidifiers and was satisfied with them, so I purchased 3 additional Pro humidifiers. First of all, the difference compared to the previous model is that the fan is located on top of the water tank, making it difficult to separate the water tank. In the previous model, rather than pouring water from the top, you took it with a water container and discarded the remaining water and filled it with water. However, with this model, it was instructed to pour water from the top and wash it about once a week. So, it has its own cleaning mode and descaling mode, so once a week you put tap water in it to run the cleaning mode, and once every three months you put in citric acid and maintain it through the descaling mode. Also, there is no heating mode. The previous model had a heating mode, so the humidified air was not cold. The advantage of this model is that the water tank is 1 liter larger. It also has a UV sterilization function and seems to be a little quieter. And the display and ambient light are prettier, and the brightness changes depending on the surrounding brightness and can be turned off automatically at night. The build quality also seems to be higher. This is a satisfactory product.
It took a while for it to be delivered, but the humidifying performance is really great ^^
