Segmentation by type categorizes the market into polymeric, ceramic, and composite membrane elements, each influencing the total market valuation. Polymeric membranes hold the largest portion, approximately 60 %, due to their cost‑effectiveness, ease of manufacture, and suitability for low‑pressure water and air filtration tasks. Ceramic membranes represent about 25 %, favored in high‑temperature heat‑exchange and chemically aggressive environments where durability outweighs higher material costs. Composite membranes, combining polymeric and inorganic layers, occupy the remaining 15 %, offering tailored performance for hybrid applications such as simultaneous filtration and heat recovery. The distribution of these types aligns with the application profile, reinforcing the market taxonomy and guiding investment decisions across the household segment.
