Whole House Water Filter System Filter Cartridge Change Instructions

2 Stages of Powerful Water Filtration Remove Sediment, Dirt, Rust, Sand, Silt, and other suspended solids which can cause build-up and clogging.

Whole House Filter Stage 1 Sediment Fitration
5 Micron Fine Sediment Filtration

Removes Dirt, Rust, Sand, Dust, Silt, and other particles from water down to 5 microns. This primes the water for the finer sediment filtration in stage 2, and extends the life of the next filter.

Whole House Water Filter Stage 2 Ultra-Fine Sediment Filtration
1 Micron Ultra-Fine Sediment Filtration

The 2nd stage filter further filters the water, removing particles from teh water down to 1 micron (0.00004" - roughly 1/50th the size of a human hair). This provides excellent protection for your plumbing, fixtures, and appliances from damage due to sediment buildup.
