All along, “haze” has been a focus of public attention, especially in cities with relatively high PM2.5 levels, where whether to go out depends entirely on the weather and whether the PM2.5 index explodes. The Luftmy editor knows that most people obtain PM2.5 information from weather forecasts or online sources. Both sources report the overall average value measured at several specific meteorological monitoring stations during a specific period, which may differ from the surroundings or indoor air quality.

Why spend money to buy an air quality detector for your home?

Officially published PM2.5 data come from specific outdoor monitoring points and periods as overall averages. Moreover, indoor and outdoor air quality differ greatly. Therefore, official PM2.5 data can only serve as a reference for travel, not a definitive basis, especially in households with children. Having a portable air quality detector at home allows you to monitor indoor air conditions anytime. The sensor inside can measure the PM2.5 particle concentration in the flowing air to determine whether purification is needed, making a portable air quality detector very practical.
