This is a personal sterilization and deodorization device that can be easily used anywhere with a computer, mobile battery, or USB adapter, thanks to its USB connection. It is compact and lightweight, weighing only 230g. 【Mechanism for Clean Air】 By irradiating a high-density photocatalytic filter, which is our unique technology, with UV LED light, active oxygen (OH radicals) is generated on the surface of the filter, creating oxidative power. This sterilization and deodorization device quickly removes bacteria and odor-causing germs present in the air passing through the activated filter in just 1/300 of a second. It removes micro-droplets and germs, keeping the air clean at all times. Conventional HEPA filter air purifiers carry the risk of harmful substances dispersing during filter maintenance, but KOROSUKE's photocatalytic filter has self-regenerative capabilities and is maintenance-free, eliminating the risk of harmful substance dispersion. Unlike ozone air purifiers or hypochlorous acid air purifiers, it does not release ozone or chlorine, making it highly safe and allowing you to care for the air with peace of mind. ● For more details, please contact us or download the catalog.
