Home drinking water filters for dirt, rust & extra fine sediment removal

Dirt/Rust & Sediment Filters

Extra Fine Sediment Filtration – 1 Micron Particles

Problem
Extra fine dirt, dust and particulates in your water.

Solution
The Keystone 1 micron sediment filter cartridge is the same pleated construction as our 5 and 10 micron cartridges. This is our most tightly woven cartridge for home water applications. Service life will be greatly reduced if heavy sediment, such as sand, is in your water.
