Dust particles, etc.
2, organic particles: plant fibers, animals
Hair, hair, horny, dander, etc.;
3, living particles: unicellular algae, bacteria
Classes, protozoa, bacteria and viruses.

Particle size classification

1, visible particles: visible to the naked eye, particle diameter
Size 10μm;
2, microscopic particles: can be seen under the ordinary microscope
See, the particle diameter of 0.25 ~ 10μm;
3, ultra-micro particles: in the microscope or electronic display
Microscope can be seen, diameter less than 0.25μm

Indoor air pollutants

1, decoration and building materials pollution: formaldehyde, benzene,
Chlorine, hydrazine.
2. Daily life pollution: cooking waste
Gas pollution, the body's own excretion, pets
Pollution, domestic garbage.


Classification of hazards
1. Respirable particles (high hazard) Small particle size
At 10μm does not settle to the ground in a short time
Susceptible to inhalation by the human respiratory system
Into the particles;
2. Sedimentable particulate pollutants (low risk):;
The particle size is larger than 10μm in a short time
Settling particles that settle to the ground.

Air Pollution
It refers to a particle with a diameter of less than or equal to 2.5 microns. Its diameter is less than 1/20th of the thickness of human hair.


Due to various pollutions, air purifiers must be used to filter these air pollutions.

What is an air purifier?
It is an electrical product that removes various dust, harmful and odorous gases, and harmful bacteria and viruses in the air through physical filtration, electrostatic dust removal, activated carbon adsorption, etc., to improve air quality and clean air. Air purifier (air refresher).
