The Tier1 SWC-45-2030 has a 30-micron rating, making it ideal for reducing coarse sediment, dirt, sand, rust particles, and silt from your water supply. This 30-micron filtration is well-suited as a pre-filter stage for well water or municipal water containing larger particulate matter, helping protect downstream filters, appliances, and plumbing fixtures from sediment damage.

The Tier1 SWC-45-2030 measures approximately 20 inches in length and 4.5 inches in outer diameter (Big Blue size). It is a direct comparable replacement for the Hydronix SWC-45-2030 and fits standard 20" x 4.5" Big Blue whole-house filter housings, including popular models from Pentek, Culligan, and American Plumber. Always verify your housing size before ordering.

The Tier1 SWC-45-2030 typically lasts 3 to 6 months, depending on your water quality and daily usage volume. Homes on well water or with higher sediment levels may need to replace the filter more frequently, while households on cleaner municipal water can often extend service life closer to 6 months. Monitor for drops in water pressure as a sign it's time to replace.

The Tier1 SWC-45-2030 is constructed with tightly wound polypropylene string over a rigid polypropylene core, creating a true graded-density design. The outer layers capture larger particles while finer particles are trapped deeper in the filter, maximizing dirt-holding capacity. It contains no adhesives, binders, or surfactants, making it safe for potable water applications and compatible with a wide range of liquids and temperatures up to 165°F.

The Tier1 SWC-45-2030 is manufactured from FDA-compliant polypropylene materials suitable for potable water use. As a mechanical sediment filter, it is designed to reduce visible particulates such as sand, silt, rust flakes, scale, and dirt down to 30 microns. Note that string wound sediment filters do not remove chlorine, taste, odor, or chemical contaminants — for those, pair this pre-filter with a carbon block filter downstream for complete whole-house filtration.
