3. 24-hour degradation in the dark as well as in artificial light such as fluorescent light
The conventional photocatalysts can only be used in places where sunlight hits, such as exterior walls. However, thisproduct works well in rooms where sunlight cannot penetrate easily, windows with UV-cutting glass, incandescent lightbulbs (halogen and mini-krypton bulbs), fluorescent lamps, and LED lights.
Furthermore, even at night when there is no light, such as while sleeping, apatite works by absorbing bacteria firmly,and decomposes and removes the source of virus, bacteria and smell when the light hits.
