Types of HEPA filters
HEPA Air Filter is a device specially designed to purify the air, which mainly uses high efficiency filter materials, such as glass fibre, to filter tiny particles in the air. HEPA filters can effectively capture airborne dust, pollen, bacteria, viruses, and other particles with sizes of more than 0.3 micrometres, thus providing clean and healthy indoor air.
HEPA Air Filter Classification:
| Mean Fractional Efficiency  | IEST RP-CC001.3  | European Union EN1822 Class  | Typical Controlled Contaminant  | Application  | |
≧95% at 0.3µm  | N/A  | H10  | ≧85% at MPPS  | Particle size bigger than 0.3µm (Virus) (Carbon dust) (Sea salt) (All combustion smoke) (Radon progeny)  | All types of cleanrooms  | 
≧98% at 0.3µm  | H11  | ≧95% at MPPS  | |||
≧99.97% at 0.3µm  | TYPE A  | ||||
≧99.99% at 0.3µm  | TYPE C  | H12  | ≧99.5% at MPPS  | ||
≧99.995% at 0.3µm  | H13  | ≧99.95% at MPPS  | |||
≧99.999% at 0.3µm  | TYPE D  | H14  | ≧99.995% at MPPS  | ||

HEPA air filters work by using multiple layers of dense fibre mesh to physically filter tiny particles from the air without relying on chemical methods. As air passes through the HEPA filter, tiny particles are trapped in the filter material and clean air is released. This design makes HEPA filters a highly effective air purification device that can significantly improve indoor air quality and reduce the impact of allergens and pollutants on the human body.
Overall, HEPA air filters are designed to provide efficient air purification technology that effectively filters tiny particles from the air, guaranteeing that people breathe clean, healthy air in their indoor environments, ensuring that industrial production is carried out safely and efficiently.
