The MFPDRS5 Cartridges feature an advanced "triple layer" tri-gradient filtration design, offering up to three times the dirt-holding capacity of similarly sized sediment cartridges, and significantly outperforming standard spun or string-wound filters. Each of the three gradient density layers is designed to filter particles by size: larger particles are captured by the outer layers, while finer particles are filtered by the inner layers. This design maximizes the efficiency and lifespan of the filtration media.
