Comparative analysis of the advantages and disadvantages of "medium type" or "electrostatic type" air purification

In recent years, the problem of air pollution has become more and more serious. In the autumn and winter seasons, the demand for air filtration products for commercial and civil use has increased sharply, and the frequency of replacement of industrial filters has also increased. Air pollution not only harms human health, but also restricts the development of enterprises. With the continuous development of technology, the equipment used in industrial production has become more and more advanced, and the production process has become more and more sophisticated. A small particle of dust may affect the product quality. Nowadays, air filters have become the mainstay of many companies. A must-have. With the increase of air pollution, commercial and civil air purifiers are used more and more widely. Among the many types of air filtration, one is the traditional filter type purification, and the other is the electrostatic type purification. They have their own strengths and continue to improve with the advancement of science and technology. The editor researched and sorted out the purification and filtration product brands in the industry, and analyzed and compared:

    Activated carbon filter (media type)

Advantages: Activated carbon is a porous carbonaceous material with highly developed pore structure. The porous structure of activated carbon provides it with a large amount of surface area and can fully contact with gas (impurities), thus giving activated carbon its unique adsorption performance. Make it very easy to achieve the purpose of collecting impurities.

Disadvantages: Ordinary activated carbon can not absorb all toxic gases, it has low efficiency, saturated absorption, easy to desorb and release harmful components again

    Chemical fiber, glass fiber filter media (media type)
Advantages: HEPA, which means high efficiency air filter in Chinese, is a filter that meets the HEPA standard. The effective rate for 0.3 micron particles is 99.99%. The characteristic of the HEPA net is that the air can pass, but the fine particles cannot pass. The HEPA filter is composed of a stack of sub-glass fiber membranes that are continuously folded back and forth, forming a wavy gasket to place and support the filter medium.
Disadvantages: The filter needs to be cleaned or updated regularly, and the later cost is higher.

Electrostatic filter (electrostatic type)
Advantages: The tungsten wire of the electrostatic precipitator continuously releases high-voltage static electricity, so that the dust and bacteria that come in with the air are positively charged, and then adsorbed by the negative electrode plate. It can filter dust and smoke smaller than cells. Comprehensively protect the respiratory system and greatly reduce the risk of cancer. It is easy to use. After one or two weeks of use, black dirty water can be washed out and secondary pollution can be reduced. There is no need to replace expensive consumables, and it can be electrostatically sterilized. The electrostatic tungsten wire releases high-voltage static electricity, which instantly kills bacteria and viruses, and is more effective in eliminating colds and preventing various infectious diseases.
Disadvantages: The quality of the brand varies from good to bad. If some manufacturers do not control ozone release well, it is easy to cause harm to the human body. An ozone separation screen is attached when you need to purchase. The trace ozone generated under the action of a high electric field is completely decomposed and filtered by the ozone removal filter. The brand of the filter will not produce ozone hazard ; in addition, the contrast media type filter is used up and replaced with a new one. , The electrode plate needs to be cleaned manually on a regular basis.

The following lists the economic comparison between the electrostatic filter and the bag-type F7 efficiency filter for reference:
