Filter material selection based on filter medium
For tea filtering, electronic products filtering , dust filtering and other liquid filtering which not need very high precision filter, polyester mesh is better choice as it is much cheaper than stainless steel mesh.
For medium which require high wear-resistant, Nylon6 mesh and stainless steel mesh are the best choice, and stainless steel mesh has better performance than Nylon6.
For foods filtering, it is better to use Nylon66 and stainless steel material. But stainless steel material price is higher than Nylon66 material, you could select the best material according to your actual demand.
