The photocatalytic mosquito killer is the most environmentally friendly and efficient mosquito killer after years of research and development. The trapping lamp has a wavelength of 360-380 nanometers, which is harmless to the human body. Moreover, the photocatalytic reaction can also purify the air, effectively kill all kinds of bacteria in the air, and absorb all kinds of harmful gases. It has the same killing effect on flies and moths. The overall performance is not comparable to other mosquito killers. Its biggest feature is that it can continuously hunt and kill blood-sucking female mosquitoes in the same space, thereby effectively interrupting the mosquito population reproduction cycle in a larger area around the space, and achieving the effect of killing mosquitoes and flies in groups. The photocatalytic mosquito killer uses the eddy current of the fan to dry the mosquitoes to death. There is no "popping" noise of the electric mosquito trap, and there is no high voltage to prevent accidents. So it is safer and more reliable. It can be widely used in: homes, hotels, restaurants, student dormitories, hospitals, cafes, bars, theaters, office spaces, canteens, kitchens, breeding farms, food processing plants, factory buildings, field, etc.
