From the purification technology divided into electrostatic dust removal, filter filtration, negative ion purification
1, electrostatic dust removal type
Electrostatic air purifier is a high-voltage electrostatic field to make the gas ionization, will be charged dust particles in the air adsorbed to the electrodes, to complete the air purification process. However, when the integrated board of this purification method is dusty, it will make a crackling sound and is easily damaged. Moreover, this filtration method produces ozone, which is irritating to human respiratory organs.
2, screen filter type
The purification principle is built-in fan pumping, air is pumped, through the screen mechanical filtration, that is, when the dust rushes to the screen, after - layers of barrier, some large particles of dust blocked in the screen. But for some fine dust, it will pass through the mesh of the filter, and can not effectively eliminate PM2.5 hazards. Even the most efficient HEPA filters can only filter particles above 0.3 microns. Filtering effect and noise is also directly proportional to the filtering effect, the better the filter, the denser the filter, the particles can be blocked the more tiny, but then bring the air through the difficulty, must increase the fan power to pump, and fan power increases lead to an increase in noise, will have a certain impact on the rest. And the filter needs to be replaced regularly, the later consumables cost is higher, but if not replaced in time and will form a secondary pollution.
Negative ions active purification technology
Negative ions and airborne bacteria, dust, smoke and other positively charged particles combined, and aggregated into a ball to land and eliminate PM2.5 hazards. Experiments have proved that the smaller the diameter of floating dust, the easier it is to be precipitated by negative ions.
Chinese negative air ions and ozone research society expert group to write the "negative air ions in health care and environmental protection in the application of" a book has also repeatedly said: light ions in the air as small as 0.01 microns, difficult to remove in the industrial particles of dust, there is a hundred percent of the effect of sedimentation removal. When the concentration of negative ions in indoor air reaches 20,000 per cubic centimeter, the amount of dust in the air will be reduced by more than 98%. PM2.5 can enter the lungs of particles with excellent results. So in the air containing a high concentration of small particle size negative ions, PM2.5 in the most harmful diameter of 1 micron below the dust, bacteria, viruses, etc. almost zero.
Negative ion purification does not need a filter does not need a fan, but through the release of negative ions to remove small particle size particles in the air, zero noise, zero supplies, no maintenance costs later. The eco-negative ion generation chip technology, nano fullerene negative ion releaser technology, Eco-negative Ion Technology with Negative Ion System and Pollutant Collection System has been able to generate the ecological equivalent of nature's small particle size negative oxygen ions, high concentration, high purity, no ozone generation, effective purification of indoor air.
