Tier1 1 Micron 20x4.5 Water Filter | Spun Wound Polypropylene Whole House Cartridge | Replacement for Pentek DGD-2501-20, 155360-43, P1-20BB | Fine Sediment & Rust Filtration | 4.5 x 20 Water Filter

Q. What is this filter used for? A. This whole house sediment water filter is designed to help reduce common sediment such as rust, dirt, sand, silt, and particulate matter before water enters household plumbing systems, appliances, and downstream filtration stages. Q. What does 5 micron filtration do best? A. A 5 micron rating is widely used for whole house sediment control because it balances effective particle reduction with steady household flow, making it suitable for both municipal water supplies and light well water conditions. Q. Is this filter compatible with other common brand replacements? A. Yes. This cartridge is commonly used as a replacement for models such as Pentair ECP5-BB, CP5-BBS water filter, CP5-934, Pentek CP5-BBS-D, American Plumber W5CPHD, 155184, 255490-43, Ametek ECP5-BB, Bruner CP5-BB, CP5-BBS, CP5-BBS-D, FM-BB-10-5, OmniFilter RS15, and PC05-BB-S in systems that accept 10 inch x 4.5 inch whole house housings. Q. How does pleated polyester filtration work? A. Pleated polyester uses surface filtration, capturing sediment on the outer pleated media. The increased surface area allows water to pass through while distributing sediment across the cartridge face, supporting consistent flow under moderate sediment loads. Q. Where is this filter typically installed? A. This filter is typically installed as a first-stage whole house sediment filter at the main water entry point to reduce dirt, sand, and debris before water enters household plumbing. Q. Is this compatible with large diameter whole house housings? A. Yes. The 10 inch x 4.5 inch size is designed to fit most standard large-diameter whole house filter housings that accept 4.5 inch by 10 inch cartridges. Q. How often should this filter be replaced? A. Replacement timing varies based on water conditions and sediment load. Many households monitor flow or pressure changes to determine when cartridge replacement is needed for continued performance.

• COMPATIBLE REPLACEMENT MODELS – This 5 micron 10 x 4.5 pleated polyester sediment water filter is a replacement for Pentair ECP5-BB, CP5-BBS water filter, Culligan CP5-BBS-D. CP5-934, CP5-BBS-D, Pentair CP5-BB, American Plumber W5CPHD, 155184, 255490-43, Ametek ECP5-BB, Bruner CP5-BB, FM-BB-10-5, OmniFilter RS15, PC05-BB-S; fits most 10 inch x 4.5 inch whole house housings
• 5 MICRON SURFACE SEDIMENT FILTRATION – Pleated polyester media captures common household sediment such as rust, dirt, sand, silt, and particulate matter, supporting improved water clarity while maintaining consistent flow in whole house systems.
• PLEATED POLYESTER MEDIA DESIGN – Surface filtration with increased pleated area allows higher dirt exposure across the cartridge face, helping support stable flow performance in municipal and light well water conditions with moderate sediment.
• SERVICE LIFE VARIES BY WATER CONDITIONS – Replacement frequency depends on sediment levels, water quality, and micron rating; finer filters capture smaller particles more quickly, so monitoring flow or pressure changes helps determine when cartridge replacement is needed.
• IDEAL WHOLE HOUSE PRE-FILTER – Commonly used as a first-stage sediment filter to help protect plumbing lines, appliances, valves, and downstream filtration equipment from sediment buildup and premature wear.
