In recent years, many cities in China have frequently experienced haze weather events. Air pollution continuously affects our health, and environmental issues have attracted widespread social attention. With the rise of public health awareness, air quality monitoring and air purification products have gained broad attention. Notably, the intelligent experience of air monitoring and purification products makes fresh air no longer a luxury.

Driven by the market, the Leufmy editor noticed that the domestic air purifier market is developing rapidly, with fierce competition between old and new brands. According to relevant statistics, in 2015, the average price of the ten most popular air purifier products among consumers was 4566 RMB, with seven of them priced above 3000 RMB. For products over 2000 RMB, overall consumer attention reached 72.2%. This shows that the mid-to-high-end purifier market will remain a key focus for manufacturers in the future.

Air purifier products differ from air conditioners. For ordinary consumers, it is difficult to have a direct sense of whether the purchased air purifier is effective, and objective evaluation requires relevant monitoring data. Therefore, dust sensors have gradually attracted industry attention. Dust sensors are the most important bridge connecting air purifier products with users, as they can detect the concentration of harmful components in the air.

PM2.5 dust infrared sensors are applied in: air conditioners with purification functions, air purifiers, in-car purification devices, portable detectors, fresh air systems, smart detectors, and more.

In the domestic and international mid-to-high-end air purifier market, the application of dust sensors is already very widespread. They are one of the essential sensors in smart air purifiers. With the rapid growth of the domestic air purifier market, dust sensor technology has also developed rapidly, especially laser dust sensors, which have experienced rapid development. Domestic manufacturers have also launched their own laser dust sensors. In recent years, this has been the fastest-growing period for laser dust sensors in China, and the products are gradually becoming mature, stable, and mass-produced.
