This is the TOSHIBA Airion Wide Deodorizer DAC-2400(W). It comes with one pack of TOSHIBA Airion Wide Deodorizing Gel Refill for 2400. I used it for about six months starting in 2018. I used it because my cat developed bladder stones and would sometimes have accidents, and I was concerned about the odor. Thanks to it, the bladder stones were treated and improved, and the accidents stopped, and I no longer worried about the smell. However, considering the possibility of recurrence, I stored it in the storage room. Since it has been several years and my cat is still healthy, I would like to offer it to someone who wants it. I have disinfected and confirmed that it works before listing it. It is effective for pet odors, the smell of damp laundry, the smell of garbage, and ammonia odors from the toilet. You can select from three modes depending on the size of the room and the strength of the odor. It also has a convenient sensor mode that automatically operates based on the odor sensor. It's compact, so it's easy to use because it can be placed in a small space. Size: Width 300 x Depth 103 x Height 255mm Please consider purchasing if you understand that this is a used item that has been stored at home for a long time. I will ship it as soon as possible, but it will likely be on the weekend after your purchase.
