Harborlite® 1900S Perlite Filter Media - 22 lb Bag

High-Performance Perlite Media for Efficient Filtration

Harborlite® 1900S is a high-porosity perlite filter aid manufactured from expanded perlite ore and designed to improve filtration performance across a variety of applications. When applied as a precoat, Harborlite forms a lightweight, highly porous filter cake that helps capture suspended solids while maintaining excellent flow characteristics.

Its unique structure promotes efficient filtration and supports longer filtration cycles by maintaining filter cake permeability. Harborlite 1900S is commonly used in aquatic, industrial, and water treatment applications where reliable particulate removal and system efficiency are important.
