What are the advantages and disadvantages of electrostatic precipitator series products of household fresh air system compared with fresh air with traditional filter screen?
HEPA filtration?
Advantages: HEPA, which means high efficiency air filter in Chinese, has an effective rate of 99.99% for 0.3 micron particles. The characteristic of HEPA is that air can pass through, but fine particles can't. HEPA filter screen consists of a stack of sub-glass fiber membranes folded back and forth continuously, forming a wavy gasket for placing and supporting filter media. ?
Disadvantages: the filter screen needs to be cleaned or updated regularly, and the later cost is high. ?
Electrostatic filtration?
Advantages: The tungsten wire of electrostatic precipitator continuously releases high-voltage static electricity, so that dust and bacteria coming in with the air are positively charged and then absorbed by the negative plate. It can filter dust and smoke smaller than cells. Fully protect the respiratory system and greatly reduce the risk of cancer. It is simple to use, and the black and dirty water can be washed out in one or two weeks, thus reducing the secondary pollution. There is no need to replace expensive consumables, and it can be electrostatically sterilized. Electrostatic tungsten wire releases high-voltage static electricity, instantly killing bacteria and viruses, which is more effective in eliminating colds and preventing various infectious diseases. ?
Disadvantages: If some brands do not control ozone release well, it is easy to cause harm to human body. In addition, the electrode plates need to be cleaned manually at regular intervals.
