Chemical Air Filters/Activated Carbon Air Filters

Chemical air filters use activated carbon media, molecular filtration technology, and advanced adsorption materials to remove gaseous pollutants and VOCs from the air. They effectively capture acidic gases, alkaline gases, ozone, formaldehyde, and various harmful chemical compounds. Common product types include honeycomb activated carbon filters and granular activated carbon filters. Widely applied in semiconductor manufacturing and industrial exhaust treatment, chemical air filters provide a core solution for controlling molecular-level contaminants (AMC).

Coarse/Primary Air Filters (Pre-Filters)

Primary air filtration is the essential first step in protecting equipment, extending filter service life, and improving indoor air quality. Designed to capture particles larger than 5μm, including dust, hair, fibers, pollen, and coarse airborne contaminants, primary air filters are available with G1–G4 efficiency ratings. Product options include panel filters, pleated filters, and washable filters, providing reliable pre-filtration solutions for HVAC and ventilation systems.

Medium Efficiency Air Filters

Medium efficiency air filters are a critical filtration stage for controlling PM2.5, smoke, and fine dust particles. They effectively capture airborne particles ranging from 1–5μm while maintaining stable airflow and low resistance. Common efficiency grades include F5–F9 / ISO ePM10–ePM2.5. Available products include bag filters, V-Bank filters, and high-capacity synthetic fiber filters, widely used in hospitals, office buildings, shopping malls, and industrial ventilation systems to improve indoor air quality.

EPA Filters, HEPA Filters and ULPA Filters

HEPA high-efficiency filters and ULPA ultra-low penetration air filters provide advanced air purification solutions for cleanrooms, laboratories, semiconductor manufacturing, and pharmaceutical industries. HEPA filters remove 99.97% of particles ≥0.3μm, while ULPA filters achieve up to 99.9995% filtration efficiency for particles ≥0.12μm. With customizable sizes and direct manufacturer supply, our high-performance filters meet the strict requirements of precision air filtration applications.
