It relates to an antibacterial copper mesh filter and a method for manufacturing the same.

Numerous casualties are occurring worldwide due to the outbreak of the COVID-19 virus. Due to this, in recent years, masks have been used as a necessity for people. However, the material of the mask actually used, that is, the non-woven fabric and the melt blown filter (MB Filter), is at the level of filtering fine dust and viruses, and cannot eradicate viruses, bacteria, fungi, and various pathogens, so it can only be used once. No, this is a reality that is emerging as a big environmental problem.

On the other hand, although the standard of living and quality of life have improved due to industrialization, the desire for improvement of indoor air quality is increasing due to the deterioration of indoor and outdoor air quality, and sales of expensive antibacterial functional products are rapidly increasing. As a result, the development of air purifiers, system air conditioner filters, automobile cabin filters, and masks has increased, and the indoor environment improvement industry is in a stage of full-scale growth.

However, sterilization, sterilization and disinfection by conventional chemicals or heat treatment for the removal of airborne microorganisms (molds, infectious pathogens, etc. present in the air) present in closed indoor spaces are difficult to achieve 99% antibacterial effect. .

In addition, antibacterial products developed so far have limitations in removing various bacteria and infectious pathogens present in life, and moreover, antibacterial copper (copper and copper alloy) has not been developed.

Accordingly, the present applicant filed Korean Registered Patent Publication No. 10-1880531 "Antibacterial insole using antibacterial copper", Korean Registered Patent Publication No. 10-1754491 "Antibacterial shoe using antibacterial copper" Korean Registered Patent Publication Registration No. Based on the experience of devising No. 10-22676171 "Filters and Manufacturing Methods", etc., antimicrobial copper pays attention to the antibacterial action of copper and the effect of blocking water veins or electromagnetic waves. We have been researching and developing filters that can block not only deodorization, bacterial eradication and foot odor removal, but also water pulse waves and electromagnetic waves, and methods for manufacturing them.
