• High flow rate carbon block "Radial Flow Filtration"
• 25-micron Nomial Outer Layer (Polypropylene) 
• 5-micron Nominal Inner Layer (GAC Inner Media) 
• Excellent for residential water purifier systems. 
• Conditions and filters water, improving taste and odor.
• Dimensions: 4.5"OD x 1.1"ID X 9 7/8"L (fits most Big Blue housings)

This filter is an excellent choice for point-of-entry applications where a higher flow rate is needed. Considered a "dual-purpose" filter as it marries the benefits of a 25-micron polypropylene shell (for sediment removal) and granular activated carbon.
