Dust is particulate matter suspended in the air, ** industrial emissions, man-made, animal soil wind, solid matter mechanical processing or crushing, organic matter incomplete combustion, etc.

Dust** is industrial emissions, combustion fumes, soil dust, etc. You can have a humidifier at home to make the air in the house moister. When there is a large amount of dust in the air and the relative humidity reaches a certain level, water vapor forms water droplets, so the dust is easy to be moistened by water and easy to absorb water.

This prevents dust from being scattered everywhere and makes it easier to clean and use an air purifier. <
