Air cleaner effect on PM2.5

(Dr. Chen Yi Kui)

Air pollution (including PM2.5), is it effective to implement a large number of air purifiers in the south?

There are three kinds of air purifiers nowadays. One is to use a strainer, the same filter as the air conditioner. The suspended particles have smaller particles than PM2.5, and there is no way to block them with the filter.

The second type of electrostatic type electrostatic precipitator absorbs suspended particles, and the suspended particles discharged from coal are not divided into small and large parts. The three-phase power supply or the single-phase power supply is also required to generate static electricity. The 220V power supply has three phase and single phase, no matter which kind of machine cannot have the different phase at the same time, the static electricity can only attach and absorb to one kind, the chromium absorbing particles can only absorb the chrome particles, the other can not, the electrostatic cleaning machine is utilized the principle of positive and negative phase suction achieves the effect of adsorption and dust removal, but it is only about three of thousand effective.

There is also an ozone machine. The ozone machine oxidizes chromium to produce toxic gas. The ozone machine is oxidized, and the oxidation should be oxidized organic. A dust storm like the mainland flew to 3,000 meters, and it slowly sank in Taiwan. Because it is too fine, this kind of dust contains more organic matter, and under the action of ozone, just like burn weeds only produce carbon dioxide is effective, and the smog from coal burning is not effective.
