The main function of sediment filter is to remove large and fine particles from a drinking water, such as sand, dirt, silt, and rust particles. These filters are multi layered graded, meaning the outer layers are more porous, catching larger particles, while the inner layers are a finer micron catching smaller particles. Each cartridge is individually shrink-wrapped. Features: Micron rating: 5 Micron Dimensions: 20" x 4.5" Individually shrink wrapped Flow rate: 5 GPM Operating Temperature: 39F~125F (4C~52C) Max. Operating Pressure: 90 PSI Removes dust, particles, and rust
