Nelsen 12x48 Filter Unit

For homes that demand higher flow and greater capacity, the Nelsen 12" x 48" Backwash-Only Filter Unit delivers a larger media bed in a complete, automatic filtration platform. The wider 12-inch tank holds significantly more media than a 10-inch unit, supporting stronger service flow rates ideal for larger households or higher water demand. It's a robust foundation for whole-home filtration tailored to your specific water issue.

System Highlights

• Nelsen C-Series EE 1" 3-cycle backwash filter valve
• Bypass valve for easy service and maintenance
• Black polyglass 12x48 mineral tank
• Basket distributor and gravel underbed
• Automatic backwash-only operation

The Nelsen C-Series control valve automatically initiates a 3-cycle backwash to clean and resettle the media bed, maintaining consistent filtration and flow without chemical regeneration. The included bypass valve allows you to isolate the system for service while keeping water flowing to the house, and the basket distributor with gravel underbed ensures even flow and proper media support within the larger 12x48 tank. Together these components keep the system running smoothly over the long term.

As a backwash-only platform, this unit is built to be loaded with the media that fits your water issue, from sediment and turbidity to taste and odor, iron, or pH correction. Filter media and plumbing connections are ordered separately, giving you full flexibility to tailor the system to your conditions. Regular backwashing keeps the media bed clean, prevents channeling, and extends media life while preserving flow rate. From Water Softener Plus on the trusted Nelsen platform, this larger 12x48 unit is an excellent foundation for high-capacity whole-home filtration in busier households.

To round out the picture, here is some added context. Backwash filters are popular because they handle a wide range of water problems simply by changing the media inside, with no salt or chemicals required to operate. The control valve runs an automatic backwash on a schedule, lifting and rinsing the media bed to flush captured particles and keep flow strong. That makes the unit a low-maintenance, adaptable choice for treating sediment, taste and odor, iron, or pH at the point of entry.

Selected by Water Softener Plus for reliable performance and easy installation, it is built to keep your water treatment system running smoothly for the long term.
