The high-speed streamer also irradiates the water used for humidification and the humidifying filter, suppressing the bacteria that cause slime in the water. It fills the room with the clean moisture of water. (Excerpt from the instruction manual) I regularly clean and maintain it. I am a non-smoker and do not have any pets. Although it has been used for several years, the filters are relatively clean. Please consider this item, understanding that it is used.
