As air pollution issues such as fine dust particles become increasingly severe, the consumption of air purification devices equipped with various types of filters has surged. Polypropylene (PP), commonly used as a filter material, is easy to process and exhibits excellent physical properties. However, its non- biodegradable nature makes recycling difficult, leading to secondary environmental pollution during landfills or incineration. To address this issue, this study fabricated high-basis-weight filter basepaper by mixing bamboo pulp produced via organosolv pulping with low melting point polyester (LMPET), polyethylene (PE)/polypropylene (PP) fibers, and activated carbon fibers using a wet-laid process on a pilot-scale paper machine. Analysis of the filter efficiency depending on the mixing ratio and basis weight revealed that the bamboo-based basepaper achieved up to 6% higher dust particle filtration efficiency for the 3.0–5.0 µm range and exhibited 40–50% lower differential pressure compared to PET Spunbond, commonly used as a filter substrate. Furthermore, the quality factor (QF), which comprehensively considers filtration efficiency and differential pressure, showed that bamboo-based basepaper achieved a value 2.3 times higher than PET Spunbond, demonstrating superior performance in air permeability and energy efficiency. These results indicate that environmentally friendly bamboo-based basepaper has the potential to reduce long-term operating costs and serve as an economical and sustainable carbon-neutral filter substrate, providing a viable alternative to conventional petroleum-based filter materials.
