Place testing instruments and interpret data:

Place the testing equipment in the most frequently used room of your home, such as the living room or bedroom. Make sure the instrument is placed in a well-ventilated area away from direct sunlight and other sources of interference. The instrument takes a while to collect data, usually from a few hours to a few days. The data collected can be interpreted via the display on the instrument or via an app connected to a phone or computer. Understanding the changes in PM2.5 concentration can help us judge the quality of indoor air quality.

Practical suggestions for improving the quality of your home environment:

In addition to measuring PM2.5 concentration, we can also take some practical methods to improve the quality of the home environment. First, keep the room ventilated and open windows frequently, especially when the weather is nice. Secondly, using an air purifier can effectively filter particles and pollutants in the air. Choose an air purifier that meets your needs and replace the filter regularly to maintain its effectiveness. In addition, you can also pay attention to reducing indoor pollution sources, such as tobacco smoke, chemical cleaners and harmful gases. Choose green and environmentally friendly household products, and clean and dust regularly to reduce the accumulation of indoor particulate matter.


By measuring PM2.5 concentration at home, we can better understand indoor air quality and take corresponding measures to improve the quality of the home environment. Choosing the right PM2.5 detection instrument, placing it in the right location, and interpreting the measurement data are key. In addition, through practical methods such as ventilation, using air purifiers, and reducing pollution sources, we can further improve the home environment and create a healthier and more comfortable living environment. Regular PM2.5 measurements can help us monitor and manage indoor air quality in real time, bringing a better quality of life to our families.
