Custom Filters
Antibacterial Filter (Purafil Fiber Sterilization Technology)
Product Overview
Today, PM2.5 HVAC filters are already commonplace on the market. Some products go further and impregnate filter media with plant extracts to inhibit bacterial growth. However, products that truly kill bacteria and viruses are rare.
Combining its processing strengths, Baisheng Tech has introduced the advanced Purafil fiber sterilization technology from the United States, compositing germ- and virus-killing fibers into the filter media. The developed automotive HVAC filter delivers high-efficiency PM2.5 filtration, VOC gas adsorption, and bacteria/virus elimination — all without increasing airflow resistance.
Features & Specifications
Since activated carbon and electrostatic meltblown technologies are already common, this section only introduces the principle and effect of the germ- and virus-killing fibers.
Detailed Description
Using Purafil's special fibers, the product truly delivers the following, without increasing airflow resistance:
High-efficiency PM2.5 filtration, VOC gas adsorption, and bacteria/virus elimination.
