The Tier1 DGD-2501-20 comparable whole house sediment water filter features a dual-gradient density design with an outer layer rated at 25 microns and an inner layer rated at 1 micron. This gradient structure allows larger particles like sand, silt, and rust to be trapped in the outer layer, while finer sediment is captured by the denser inner core, extending filter life and maintaining consistent flow throughout your home.

The Tier1 DGD-2501-20 comparable sediment filter is designed to last approximately 3 months or up to 30,000 gallons under typical household conditions, depending on your incoming water quality and usage. Homes with well water or high sediment levels may need to replace the filter more frequently. Replacing on schedule maintains optimal flow rate and prevents sediment buildup from affecting downstream appliances.

The Tier1 DGD-2501-20 comparable filter measures 20 inches in length by 4.5 inches in outer diameter (Big Blue size). It fits standard 20" x 4.5" whole house filter housings, including Pentek, Culligan HD-950A, American Plumber, and other compatible Big Blue systems. Always confirm your housing accommodates the full 20-inch length before installation.

The Tier1 DGD-2501-20 comparable whole house sediment filter is manufactured from polypropylene media tested against NSF/ANSI Standard 42 for material safety and sediment reduction performance. It is constructed from FDA-compliant materials to ensure it is safe for potable water use throughout your home's plumbing system.

The Tier1 DGD-2501-20 comparable whole house sediment filter is specifically engineered to reduce sediment, sand, silt, rust, scale particles, and dirt from your incoming water supply. Its dual-gradient 25-to-1 micron design protects plumbing, water heaters, washing machines, and downstream filtration systems like carbon or RO units. Note: this is a sediment-only filter and does not remove chlorine, taste, odor, or chemical contaminants.
