What are the air purification technologies for treating solid pollutants in the air?portable air pur

　　Activated carbon purification technology

　　Activated carbon is made by activating carbonaceous materials such as wood, coal, fruit shells, etc. under high temperature and hypoxia conditions. The adsorption principle is physical adsorption! It has strong adsorption to solid particles and can absorb dust, particles, free molecules in the air, etc.

　　Negative ion purification technology

　　Based on the application of the air negative ion generator, the negative ions produced by itself can be used for ion adsorption and purification of harmful substances such as dust and smoke in the air. The purification effect of dust and dust solid pollutants is obvious.

　　HEPA purification technology

　　HEPA is composed of a stack of sub-glass fiber membranes that are continuously folded back and forth, forming a wavy gasket to place and support the filter medium. The filtering effect of HEPA is proportional to its surface area. It is also a physical adsorption purification. The purification effect of dust, solid particles and odor in the air is obvious.

　　Electrostatic dust collection and purification technology

　　Using the principle of high-voltage electrostatic adsorption, the filter in the air is adsorbed. Effectively remove particulate pollutants in the air, such as dust, smoke, pollen, oil fume, etc., and can also adsorb bacteria. It is easy to produce ozone harmful to the human body, and has no purification effect on chemical pollutants such as benzaldehyde.
