PM 2.5 85% -98% Anti-bacteria Filter

It is widely used for fresh air filtration for central air conditioning,fan coil return air vents, air purifiers,automotive air conditioners  etc

Antibacterial air filters are not made from a single material but rather constitute a material system, typically combining a base filtration medium with antibacterial/antimicrobial components. The core concept is: while physically trapping particulate matter, they also inhibit or kill captured microorganisms (such as bacteria, mold, etc.) through chemical or biological methods, preventing them from proliferating on the filter and becoming a secondary pollution source.

Below are the primary material compositions of mainstream antibacterial air filters available on the market:

Base Filtration Materials

This is the core component responsible for physical filtration, determining the fundamental performance of the filter (such as filtration efficiency, air resistance, and dust-holding capacity).HEPA (High-Efficiency Particulate Air) Filter

Material: Primarily composed of glass fibers, though some also use chemical fibers like polypropylene (PP).

Characteristics: Effectively captures particles larger than 0.3 microns, such as PM2.5, pollen, dust, and some bacteria and viruses. It is currently the most mainstream and efficient physical filtration material in air purifiers. Antibacterial HEPA filters are treated with antimicrobial agents applied to their fibers.

The efficiency of currently available are 85%,-98% PM 2.5 and they can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.

As dust accumulates on the filter media, the resistance increases. When the resistance reaches an unreasonable level, the filter must be discarded. Sometimes, excessive resistance can cause previously captured dust to become dislodged and re-enter the airflow; when this risk arises, the filter should also be replaced. The resistance of a filter increases with higher airflow rates. By increasing the surface area of the filter media, the relative velocity of air passing through the filter can be reduced, thereby decreasing the resistance.
