Whole House Spin Down Sediment Filter WSP100SL-ARJ-BP - Jumbo Capacity

Our review of the WSP100SL-ARJ-BP finds it best for homeowners dealing with heavy well water or visible sediment who want a low-maintenance, whole-house solution. The single biggest reason to consider this unit is its jumbo 1-gallon capacity combined with a high 25 GPM flow rate and an integrated touchscreen auto-flushing module, which together reduce the frequency of manual cleanings while keeping household water clear. It is a practical choice when durability, easy maintenance, and scale control are priorities.

Key Features

• NSF/ANSI 372 Certified: Certified lead-free construction gives added peace of mind about metal safety where the filter connects to home plumbing.
• Siliphos Add-on: Includes siliphos media to help prevent scale and corrosion, extending the life of faucets and fixtures when used as directed.
• Four-mode Bypass Valve: The bypass, filtration, shut-off, and backwash modes let homeowners route water for simple maintenance and uninterrupted service.
• Jumbo Capacity and High Flow: A 1-gallon jumbo housing and 25 GPM flow rate handle challenging well water and whole-house demands without a major pressure drop.
• Auto Flushing Module: The touchscreen-controlled auto, semi-auto, and manual flush options schedule regular cleaning and reduce hands-on maintenance.
• 316L Stainless Mesh: A pressure-resistant, food-grade stainless steel filter mesh and clear explosion-proof housing improve durability and make inspection easy.

Who It's For

The WSP100SL-ARJ-BP is ideal for homeowners on private well systems or municipal supplies with visible rust, sand, or sediment who need a robust whole-house prefilter with high flow capacity. It suits families that prefer set-and-forget maintenance thanks to the touchscreen auto-flush and backwash capability.

This unit is less suitable for anyone who needs chemical removal, softening, or ultrafine filtration below 100 microns; it is a sediment prefilter and not a replacement for carbon filters or water softeners. Professional installation is recommended for complex plumbing setups to avoid potential leaks reported by some users.
