The price of a demister is primarily driven by material composition and structural design. High-performance materials like Stainless Steel 316L, Monel, or Titanium significantly increase costs compared to standard SS304. Additionally, the wire diameter and mesh density (bulk density) are critical; higher density pads provide better separation efficiency but require more raw material, thus raising the price. For plastic demisters, PP, PVDF, or PTFE are common, with PTFE being the most expensive due to its superior chemical resistance and thermal stability.
