The classification of a filter device
1, the filter type: this type of device is as a representative of activated carbon filters, with activated carbon as the main filter material, it is possible to effectively purify benzene, formaldehyde and other harmful substances, to achieve air purification purposes. But such a device, after a period of use, the ability of adsorption will gradually weakened, so it should be replaced on a regular basis of the filter device.
2, electrostatic formula: which is a by way of adsorption of harmful substances in the air or dirt and other concentrated in the dust collecting plate by the strong electric field of the integrated plate to kill will kill, clear, so as to achieve the purpose of purifying the air . It should be noted that equipment electrostatic adsorption effect of formaldehyde, benzene and other harmful substances some slightly worse than before.
3, optical media formula: This device is also called photocatalyst, its advantage is that after the adsorption of various harmful substances, but also by a certain chemical reaction be converted into non-polluting substances in water and carbon dioxide, but this The device must play a role in sun light or ultraviolet radiation, and the clear role for the bacteria is not very satisfactory.filter fabric
Features and Benefits of the activated carbon equipment
1, chemical decomposition: The main principle is to use ion device ozone generator, it is inexpensive, functional diversity, can effectively increase the content of anions in the air, and to reduce the solid content of the dust, although there are relatively good bactericidal effect but The role of formaldehyde decomposition of the molecules is not very great.
Adsorption: This is one of the well-known role of activated carbon equipment in a short period of time, it can absorb a lot of bacteria and harmful gases, and inexpensive, but the adsorption performance according to the selected material there will be some differences, Usually after a period of use will reach a saturation state at this time needs to be replaced.
3, the multi-layer filter: mainly used in the composite air equipment, better filtering effect, can significantly redu ce the the solid dust content of the air, but the price is high, and the filter can not be regenerated, some time after To replace, more supplies.
