Hydronix 20-inch Jumbo Dual Stage Water Filter - GAC

Hydronix SDP4520 20-inch Jumbo Dual-Purpose Water Filter

The Hydronix SDP4520 combines sediment filtration and granular activated carbon (GAC) in one cartridge to reduce chlorine taste and odour. Its radial-flow design supports higher-flow point-of-entry applications with a low pressure drop, making it a practical option for compatible whole-house filtration systems.

Two filtration functions in one cartridge

The 25-micron outer shell provides sediment filtration, while the granular activated carbon media reduces chlorine taste and odour. Water flows radially through the cartridge, helping deliver higher flow rates with less carbon fines release.

Key benefits

• Combines sediment filtration and GAC treatment in a single cartridge.
• Reduces chlorine taste and odour for more pleasant household water.
• Radial-flow design provides low pressure drop for higher-flow applications.
• Designed for point-of-entry filtration in a compatible housing.
