Puretec WU20-25M Dual 20" x 4.5" Basic Whole House Water Filtration System

High-flow whole house filtration for budget-conscious residential facilities is achieved by the Puretec WU20-25M dual-stage system. This model is specified for installation on the main cold water inlet to reduce chemicals and sediment across all property outlets. It features heavy-duty 20-inch dual housings designed for medium residences requiring high-flow performance without an external power source or chemical dosing.

The system utilizes a dual-stage filtration assembly within housings measuring 390 mm wide and 730 mm high. Internal 20-inch cartridges include a high-capacity melt blown sediment filter (MB05LD2) and a carbon block taste and odour cartridge (EC10LD2). The unit operates in liquid temperatures between 0 and 52°C and has a total depth of 200 mm, requiring protection from freezing conditions during external property installation.

Fluid velocity paths support a nominal flow rate of 60 L/Min through 25 mm (1 inch) BSP female ports. The filtration assembly handles operational pressures from 200 to 875 kPa, functioning purely on existing mains line pressure. This dual-stage unit features a 5-micron nominal rating for tiered reduction and must be fitted with a pressure limiting device if the facility supply pressure exceeds 500 kPa.

The high-capacity housings accommodate the 20-inch cartridges, with replacement typically required every 6 to 12 months based on usage and building water quality. The system protects and prolongs the service life of appliances by filtering out rust and sediment at the property entry point. It features a low-maintenance design with no moving parts and operates silently on existing line pressure. Structural mounting hardware is included for facility integration.

Features

• Dual-stage 20-inch high-flow filtration configuration provides a mechanism for whole house treatment of mains water chemical and sediment contaminants.
• Heavy-duty housing construction provides a structural barrier for the internal filtration cartridges while treating the mains supply at the building inlet.
• 25 mm BSP inlet and outlet plumbing connections provide standard interfaces for integration with residential facility cold water supply inlet lines.
• No electrical power or chemicals required for operation as the system functions purely on existing line pressure to distribute filtered water throughout the building.
• 5-micron nominal rating provides a mechanism for tiered reduction of rust and sediment from the facility supply to improve water quality at every tap.
• Protects building appliances and plumbing from contaminant buildup by reducing harmful sediment and chemicals from the property water supply line.
• Low-maintenance design with simple housing access allows for high-capacity cartridge replacement without the need for specialized knowledge.
