It is a stationary type sterilizing deodorant and antibacterial agent made by impregnating a special polymer with high-concentration picosilver ions and making it into a gel. The high concentration of silver ions impregnated in the polymer slowly vaporizes into the air, constantly sterilizing, deodorizing, and antibacterial the space over a long span. Silver ions decompose bacteria and remove the source of odors, so instead of disguising the odor with scents, the space is reset to zero base (sterile and odorless). It is also effective in preventing mold and removing viruses. Please install it in your room, entrance, shoe box, toilet, closet, inside the car, refrigerator, kitchen, next to garbage, and other places where odors, mold, and space dirt are a concern.
