PU Filter Sponge Reticulated Open Cell Foam Filters for Water and Air

Filter sponge, also known as mesh sponge or blasting sponge. The polyurethane filter sponge is made of ordinary soft open cell foam through mesh processing. The mesh processing removes the original facial mask or wall film between foam networks, and obtains the main skeleton mesh structure.

The porosity of the filter sponge is as high as 97%, with excellent breathability, good softness, and high mechanical strength.
