This is the 1st stage of filtration in the Josh's Frogs Reverse Osmosis System. It acts as a net to catch & remove particles from your water such as sand, dirt, rust, and other fine particles. By doing so, it greatly extends the lifespan of the other filters downstream.

Be sure you keep up on changing this filter. As it gets clogged, the filter will take on a brown, dirty appearance.

• Removes dirt, rust, sand, and other particles suspended in water
