Throughout the global medical and health sector, in North America and European
countries particularly, silver ion sterilization technology has been well developed
and implemented. Application of silver ion is proven stable with no side effects. It
has been recognized as the safest sterilization agent by NASA and is widely
applied in biotechnology, medical health, aerospace warships and other fields.
For years, MayAir has been introducing its advanced Argenzil Silver-ions sterilizing
technology for various application and industries. Integrated with ultrafine fiber glass
filter material, the technology can inhibit the growth and reproduction of bacteria and
microorganisms in the air by interfering the synthesis of their microbial cell wall and
protein. In the meantime, air can be well purified. The removal rate of particles size
above 0.3 μm is as high as 99.99%.
Bigger particles, fibers and fur are filtered through the prefilter, ensuring the effectiveness and lengthen- ing the life span of the HEPA filter.
Gaseous contaminants like HCHO, benzene and TVOC will be adsorbed by the activated carbon filter.
The antimicrobial high-efficiency filter adopts MayAir’s advanced Argenzil silver ion sterilizing technology to effectively eliminate all kinds of bacteria, viruses and microorganisms, Secondary pollution is eliminated at the same time. The removal rate of particle size above 0.3μm can reach as high as 99.99%.

Air filter with silver-ions
The filter is composed of advanced antimicrobial active substances and special designed fiber media. When bacteria, viruses and
other microorganisms come into contact with the surface of the filter material, the active substances will inhibit and kill them..
