With the gradual development of the global economy, the demand of human being for air quality is getting higher and higher. The 4-pins ultraviolet lamp disinfection is widely used in densely populated places such as large hotels, commercial centers, airports and high-speed rail stations. Ultraviolet radiation effectively suppresses dust, harmful gases, various bacterial pathogens and secondhand smoke in the air. The improvement of environmental quality has largely stopped the spread of disease and has added a natural barrier to human health.
