The antibacterial air filter replacement uses low initial resistance substrate as filter material with different antibacterial agents embedded or sprayed on it to kill pathogenic microorganisms or effectively inhibit their growth and reproduction.
According to the JIS L1902-2008 standard, the efficiency of removing bacteria was 93.71% after natural bacteria was treated 60 minutes. The removal efficiency is 99.98% for staphylococcus aureus and 99.99% for staphylococcus albus.
This series of filters can not only filter large particles of dust in the air but also have good antibacterial properties. Therefore, they can be used for prefiltering in the front ends of air purifiers, central air-conditioning new air units and ventilation systems to replace the G3 and G4 filters. It’s economical and efficient.
