Photocatalyst (made in Japan)
The titanium dioxide (TiO2) contained in the photocatalyst coating is irradiated by a UV ultraviolet light tube in the device to generate a catalytic process, thereby generating carbon dioxide(CO2) gas, hence simulating the carbon dioxide (CO2) exhaled by the human, thereby attracting mosquitoes.

This product uses UV lamp which produces 360-400nm Light and a TiO2 coated interior which attracts mosquitoes from afar, the fan inside the machine would suck them down into the storage box at the bottom of the trap, where they die from dehydration.
