Product Description Video https://vimeo.com/454240722 Made by Tamuratec, the only domestic manufacturer of medical ozone generators. Color: White Weight: 10.5kg Product Dimensions: W400 x D240 x H680mm Applicable Area: 100㎡ Retail Price: 305,800 yen Maintenance is simple: about once a month, remove dust from the filter with a vacuum cleaner or brush, and wipe off any white deposits around the ozone generator with a cloth! You are free from daily maintenance such as washing with water or water replacement, 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.
