  This question is the most frequently asked by   mask manufacturers . We have compiled the information and discussed with you what is meltblown electret treatment. Electret refers to a dielectric material with long-term charge storage function. It has the advantages of high efficiency, low flow resistance, antibacterial, and energy saving. On the basis of ensuring the physical collision blocking effect of conventional filter materials, it adds electrostatic adsorption. The electret treatment makes the  filter material  fibers charged, combined with the dense characteristics of meltblown ultrafine fiber materials, so a large number of electrodes are formed between the charged fibers. The charged fibers can not only attract most of the charged particles in the environment like a magnet, but also Part of the uncharged particles can be polarized, and then some pollutants with smaller particle size can be adsorbed, and even nano-sized substances such as viruses can also ...
