Thank you for viewing. This product employs a new "Dia Charge System" that separates the area that electrolytically generates the "hypochlorous acid water solution," which is the key to its sterilization and deodorization effects, from the sterilization area where the contaminated air reacts with hypochlorous acid (sterilization/deodorization). This allows for the stable generation and immediate replenishment of high-concentration hypochlorous acid water solution, enabling more stable sterilization and deodorization effects even in places with high air risk where many people come and go. Made in 2021. Size: Width 510 x Depth 310 x Height 730 (mm) Please read the profile before purchasing. The price is reviewed as appropriate, so please refrain from price negotiations. If you can pick it up in person, I will deduct 2,000 yen (within Yokohama city).
