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 are pleated and cleanable. 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. Due to manufacturing process, filter colors may vary.
