Premium 50 Micron Sediment Replacement Water Filter Cartridges (4 Pack)

The Big 20" x 4.5" Sediment Filter is often the first filter installed in the Whole House Water Filter circuit, serving as the initial point of contact between the water supply and the home. It functions as a pre-filtration unit, capturing unwanted particles such as sand, dirt, silt, rust, and other fine contaminants before the water proceeds to reverse osmosis and activated carbon filters.

Made of fine-melted polypropylene that is blown and spun into a cylinder-like form, the Big 20" x 4.5" filters effectively remove these particles, allowing downstream filters and household water appliances to perform better for longer periods. The wider dimensions of the Big water filter, compared to standard filters, enable it to process more water in less time, making it well-suited for whole-house filtration.

The sediment filter operates by allowing water to pass through its tiny holes while trapping the unwanted particles. The filter size is measured in microns, with smaller micron ratings indicating smaller holes that can capture smaller particles. For water with larger visible pollutants, a sediment filter with a larger micron size is recommended in the initial stage to prevent clogging of subsequent filters.

These sediment water filters offer superior contaminant holding capacity and flow rate compared to similar-sized counterparts. They are capable of reducing sediment particles as small as 50 microns without adding any taste, odor, or color to the water. These filters are ideal for residential, rural, commercial, industrial, and municipal applications.

The Big 20" x 4.5" Sediment Filter has a height of 20 inches (48.8 cm), an outer diameter of 4.5 inches (11.43 cm), and an inner diameter of 1.125 inches (2.5 cm). It has a micron rating of 50 and a flow rate of 5 gallons per minute (GPM). The operating temperature range is 40°F (4.4°C) to 125°F (51.7°C), and the operating pressure range is 20 PSI (1.4 bar) to 125 PSI (8.6 bar).

The product lifetime is recommended to be two to three replacements per year, depending on the water quality. The filter is wrapped and sealed, meeting the standards and regulations set by the National Science Foundation (NSF).

Overall, the Big 20" x 4.5" Melt-blown Polypropylene Sediment Filter is a highly effective pre-filtration solution for whole-house water systems, ensuring that downstream filters and appliances operate at their optimal performance for an extended period.
