Whole House Water Filter System Filter Cartridge Change Instructions

3 Stages of Powerful Water Filtration Included

Whole House Filter Stage 1 Sediment Filtration
5 Micron Sediment Filter

Removes Dirt, Rust, Sand, Dust, Silt, and other particles from water down to 5 microns. This protects your plumbing & appliances and extends the life of the carbon filters. The graded pore structure uses the entire depth of the filter - capturing larger particles in the outer layers and decreasing in size as it reaches the center. This maximizes the dirt holding capacity, giving more time between changeouts.

Whole House Water Filter Stage 2 Carbon Filter
