Purchased new from Edion in 2022 for approximately 70,000 yen. This is a high-grade model with original features added to the base model "MCK70Y". It has been completely disassembled and cleaned with citric acid for each part, so it is in quite a clean condition. You can use it immediately upon arrival without cleaning. Design: Tower type. It is a matte white (-W) model. Water supply method: Supports "top-fill" where you can pour water directly from the top without removing the tank. Air purification: Equipped with "Twin Streamer," which doubles the decomposition speed of harmful substances compared to conventional models. The TAFU filter ensures long-lasting high dust collection efficiency. Humidification: Maximum humidification capacity of 700ml/h. The humidification filter uses Kobayashi Pharmaceutical's persistent antibacterial agent "KOBA-GUARD" to suppress bacteria. Original features: Includes additional features such as "display lamp adjustment" not found in the general model. Maintenance and running costs Filter life: The dust collection filter and humidification filter are estimated to be replaced approximately every 10 years. Electricity bill: When used for 24 hours in standard mode, it is approximately 10 yen per day (estimated).
