Thank you for viewing. I purchased this new and kept it as a spare. Since my other unit has been working without any problems, I never used this one and it has been stored away. As I don't anticipate using it in the future, I'd like to offer it to someone who can make use of it. This product is a Daikin "Hikari Cleair" in-car air purifier. This model was unique in its ability to perform powerful, full-scale air purification with its automatic mode, two types of filters, and photocatalytic function. I recall it cost around 30,000 yen at the time. *** ※ In order to list this item, I reopened the box and tested it. The original box, the main unit, and the cord all show signs of aging and some soiling due to humidity. The motor is working, and the strength adjustment is also functioning. The light regeneration function is working, with a blue light illuminating. The cord's on/off switch and operation mode jog dial are both working. There are three levels of indicator lights that react to air pollution, but I was unable to test all of them, so I could only confirm the first-level green light. ※ The filters have aged, so it's recommended to replace them. The main unit and cord could likely be cleaned with a neutral detergent, as they are unused. ※ During the power-on test, all functions seemed to be working. This item is being sold as-is due to its age. Thank you.
