Sediment
 Filters are the standard sediment pre-filter that come with many 
Reverse Osmosis systems. The Sediment Filter will remove silt, rust, 
sand, etc. These filters work with Hydro-logic systems as well as Ideal 
H2O. Match the filter to the size of your Reverse Osmosis system. Most 
filters last 6 – 12 months with regular cleaning.
