The filter paper of range hood is mainly designed to filter oil fume and grease particles, but its structure and material are not suitable for filtering water. The filter paper of range hood usually adopts fiber material or multi-layer filter screen structure, and its purpose is to capture and adsorb oil particles in the oil fume, thus purifying the air and preventing oil from entering the exhaust pipeline. The size and properties of water molecules are different from those of oil particles, and the pore structure of filter paper can not effectively prevent water molecules from passing through, thus playing a role in filtering water. If you need to filter water, choose a filter element or screen specially designed for water treatment.
