The air purifier on the market in what function?

From the beginning of the last century in 80s, indoor air purifier has undergone continuous improvement, the first, second generation experience, purely physical way to remove suspended solids and dust in indoor air, it has produced the third generation of products, in the removal of indoor harmful gas function has been improved very prominent. In recent years, some professional models, has been the use of advanced nanotechnology, make efficient catalysis and photocatalysis purifying technology. Under normal temperature and pressure to a variety of harmful gases and chemicals into harmless and tasteless substance, coupled with the inter particle material has been developed (such as high density fiber filter layer HEPA), has been effectively removed as low as 0.3mm (human hair 1/300 diameter) of the suspended particles, so by physical adsorption the past simple change simultaneously with chemical decomposition, and improve the adsorption efficiency for removing pollution types and materials, and will not be able to produce the two pollution, the service life of the catalyst material is 20 times that of ordinary materials, greatly reduce the use of supplies into the air purifier, is the most ideal current component. The air purifier includes the main way of purification:

1. high density filter efficiency particulate air filter (High HEPA Filter)

HEPA filter is the world recognized the purification efficiency of air filter materials is the highest, the fine dust in the air to 0.3 micron (about 1/300 the size of the hair is sucked into the dust filter, high efficiency up to 99.97% above. And at the same time will be greater than 0.3 microns across the live bacteria, reduce the amount of bacteria in the air

2. ultraviolet germicidal lamp Ultra-Violet (UV) Lamp

Can be divided into for bacteria and viruses UVC Lamp and UVV Lamp in addition to taste and. UV can change the bacterial DNA, in order to prevent them from normal reproduction (Reproduction), the amount of air will slowly reduce bacteria

3. photocatalytic Photo-catalysis Type

Mainly for harmful chemical substances, bacteria and viruses. Mainly with the "light" - General ultraviolet (UV Light) and effect

4. activated carbon filter Actived Carbon Filter

Mainly for odor and harmful chemical substances, but when used for a period of time, the material will be saturated with "Saturated" effect will disappear and the need for replacement

5. electrostatic dust smoke detector Electrostatic Chamber

For smoke, secondhand smoke and dust, less than 0.01 microns (about hair is 1/10000 size). Basically can also kill all bacteria and viruses, the carbonization, but also effectively remove oil and smoke

6. Negative ion release negative ions

Negative ion by corona discharge and the oxygen in the air to decompose and produce. Some people think that the negative ion is "air vitamin", promote, ease the tension The new supersedes the old.. But certainly, when moderate negative ion content in the space, the interior space of the air is fresh, as in the outside environment. In addition, the negative ions also have a dust collecting effect, but the efficiency is small; and the negative ion must be uniformly dispersed into the air with the wind in order to play a role. For a chance to produce ozone negative ion generation old release, made of two pollution
