- COMPATIBLE REPLACEMENT MODELS – Designed to fit standard 20 x 4.5 whole house filter housings and a replacement for Pentair DGD-7525, DGD-7525-20, 155356-43, and P20-20BB; suitable for most 4.5 x 20 water filter housings.
- 23 MICRON DEPTH SEDIMENT FILTRATION – Spun wound polypropylene construction captures larger sediment particles throughout the cartridge depth, helping reduce sand, rust flakes, silt, dirt, and scale commonly present in well water and municipal water systems.
- HIGH DIRT HOLDING CAPACITY DESIGN – The graded density depth structure traps heavier particles on the outer layers while allowing water to continue flowing through inner layers, supporting consistent performance in high-sediment conditions compared to basic surface filters.
- 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 or entry-point sediment filter to help protect plumbing, appliances, water softeners, and carbon filters from heavy sediment buildup and premature wear.
