The testing content includes the purification efficiency, removal rate, and clean air volume of formaldehyde, PM2.5, nitrogen oxides, TVOC, and toluene, the odor removal effect of ammonia, trimethylamine, and sulfur dioxide, and the disinfection and sterilization effect of bacteria, fungi, and molds in the air 1. Detection Background&Nbsp&Nbsp; In recent years, the number of cars in China has grown rapidly, and people's dependence on vehicles has become increasingly evident. In addition to indoor spaces, vehicles have become one of the main places where people stay. In order to improve the comfort of cars and continuously optimize the internal environment of cars, production enterprises use a large number of non-metallic materials and adhesives, leading to the accumulation of pollutants inside the car. At the same time, long-term exposure to outdoor sunlight accelerates the volatilization and release of pollutants, seriously endangering human health. The indoor air quality requirements are shown in the table below
&Nbsp&Nbsp; The use of an on-board air purifier for detection is an effective method of purifying the air inside the vehicle. At present, the mainstream technologies of car mounted air purifiers include room temperature formaldehyde catalytic oxidation technology, electrostatic dust removal technology, filter adsorption technology, ozone sterilization and decomposition technology, negative ion technology, and nano photocatalyst technology
