It is a spray-type disinfectant and deodorant antibacterial agent that uses an ultrasonic humidifier. The silver ions sprayed from the humidifier spread to large spaces and narrow gaps in the flow of air, disinfecting, deodorizing, and antibacterial the entire space. In addition to sterilization, deodorization, and antibacterial, it can also be expected to be highly effective in decomposing skie allergens contained in pollen, mold prevention, and virus removal. Since it is a highly concentrated silver ion not only for rooms and offices, but also for spraying applications, a single humidifier is sufficiently effective in spaces such as large halls. Use an ultrasonic humidifier and fill it with silver ionized water instead of water. Hybrid humidifiers and steam (heated) humidifiers cannot be expected to be effective. Since it is not intended for humidification, we recommend using it for about 8 hours a day. Please avoid continuous operation for more than 12 hours a day, as it may weaken your immunity.
