(1) Industrial vacuum cleaners can effectively handle dust

The so-called dust refers to all solid dispersed particles.  In the air, the amount of dust with the particle size of 0.1-10μm is the largest.  Those with particle sizes larger than
10μm are called "dustfall" and those with particle sizes smaller than 10μm are called "floating dust".  The particle size is at most about 200. m.

(2) Industrial vacuum cleaners can effectively treat smoke dust

The so-called soot is generally the product of high temperature.  It includes all agglutinatable solid particles and particles generated by agglutination of solid particles and liquid
particles.  The particle size of the smoke is usually below 0.5μm m.

(3) Industrial vacuum cleaners can effectively deal with haze

The so-called haze refers to the haze phenomenon caused by a large amount of smoke, dust and other particles in the air, which is called haze.

(4) Industrial vacuum cleaners can effectively handle fog 

Fog refers to all liquid agglutinating particles and all liquid dispersing particles with particle sizes ranging from 0.1 to 10 μ m.
