Great value! Almost new! Some parts have been modified by the manufacturer. There are multiple photos. Please check them. If necessary, I will take photos of any areas you are concerned about. (The filter has some signs of use.) *Negotiations on price are welcome. Due to the nature of the product being a reused item, no claims are accepted. Instruction manual and remote control included (unused). Almost new, unused item. Used only about 2 days a month for about a year and a half. However, as it is a used item, there is no manufacturer's warranty. Product Description Video https://vimeo.com/454240722 Made by Tamuratec, the only medical device ozone generator manufacturer in Japan. Color: White Weight: 10.5kg Product Dimensions: W400 x D240 x H680mm Applicable Area: 100㎡ Retail Price: 305,800 yen Maintenance involves removing dust from the filter with a vacuum cleaner or brush about once a month, and wiping off the white deposits around the ozone generator with a cloth! You are free from daily maintenance such as washing with water or replacing water, which are common with other models. Can be used in hospitals, pharmacies, hotels, offices, large living rooms, banquet halls, and halls. This is the top-of-the-line model with high air purification and ozone sterilization/deodorization functions. High-concentration ozone is used in environments without people for thorough sterilization. Low-concentration ozone can be used in environments with people and sterilizes slowly over time. As a measure against hay fever, it decomposes and removes pollen. For those with hay fever, this is a must-have item for your home during the upcoming pollen season. Insect repellent effects can also be expected.
