U-manga Yumanga has introduced advanced "deodorization technology" from Japan, which can effectively deal with the "bad smell=foul odor" in the air. Unlike the way aromatics mask the odor, it does not require light irradiation to exert its effect, nor does it release ozone, ions and other oxidizing substances to harm our respiratory tract. The ingredients are natural and safe, and it will not cause secondary pollution to the Earth. It provides you with fresh air with a "good taste" and makes you feel happy.
