Safe Water Technologies' Residential Sediment Filters are built utilizing SWT's FilterEase™ filter media. These filters are designed to remove ferric iron, silt, and turbidity. Sediment filtration down to the 10 - 20 µ level is common. SWT takes care of the little extras such as: machined PVC distribution systems, bypass valves, tank jackets, bolted on bases for ease of carrying, anthracite under-bedding for less channeling.
