• Highlight: This 4 x 30-inch carbon filter from RHG shields the RO membrane from chlorine and sediment in larger T-series carts, preserving membrane and resin life downstream.
• Best For: Operators of the larger 4x30 cart systems who want maximum pre-filtration capacity.
• Expert Note: The 30-inch length carries more carbon than standard 10-inch cartridges, so change intervals stretch on high-volume routes.
