Meanwhile, monofilament mesh filter bags, such as nylon mesh filter bags, will be your optimal solution for surface filtration and high flow condition of the single-layer structure and better permeability.
You can choose needle felt Filson water filter bags, generally from single or multiple layers, from 1 to 12. single layer filter bags features the best performance of liquid penetration. In comparison, multi-layer filter bags brings a progressive density design that results in gradually finer filtration.
