The photocatalyst mosquito-killing lamp, when in operation, can generate the light, heat, carbon dioxide, water vapor and flowing air that mosquitoes like. It mimicking human breathing to attract mosquitoes, drawing them away from your side and causing them to fall into the mosquito-catching cyclone, making them escape and die from drying out. Photocatalyst can also purify the air and kill bacteria and disinfect. When mosquitoes approach the machine, the system uses the wind force of the internal fan to draw them into the collection trough, dry them in the air, and achieve the effect of killing them.
