Ion generator IG-MX15-W, white, manufactured in 2020. I mainly used it in the car, placing it in the drink holder. I stopped using it when I changed to a car with nanoe, and it had been sitting in a shelf at home for a while. It was in actual use for about 3 years, and I only used it when I was in the car. (The white stain-like thing in front of the hand on the top of the main unit in the 4th image is probably dust or something that got reflected during the photo.) I remember the purchase price was around 15,000 yen at the time. It is still sold for around 10,000 yen now. I have opened the parts that can be opened and cleaned them as much as possible with alcohol and cotton swabs. Please keep in mind that this is a used item when making a purchase.
