Background
Due to the requirement of the market for air purification, HEPA Filter paper is selected for many Filter sterilizers in the market at present to form HEPA filters (namely, High efficiency particulate air filters, which are all called High efficiency air filters in Chinese). Because the filtration effect of the HEPA filter paper is very obvious, the filtration efficiency is particularly high. Meanwhile, some high-end products select a mode combining a high-intensity electric field and an HEPA filter, the filtering mode not only filters pollutants and bacterial viruses, but also has the effect of killing the bacterial viruses, and the service life of the HEPA filter is prolonged. However, in the device of the high-intensity electric field + HEPA filter in the prior art, the frame of the HEPA filter is made of plastic material.
