Description
iSpring WGB32B-KDS + WSP50ARB Whole House Water Filtration System with Auto-Flushing Spin-Down Prefilter
The iSpring WGB32B-KDS + WSP50ARB is a premium whole-house water filtration system that combines advanced contaminant reduction, salt-free anti-scale protection, and an automatic self-cleaning sediment prefilter into one complete point-of-entry solution. Designed for municipal water and compatible well water applications, this system helps reduce PFAS, chlorine, chloramine, lead, heavy metals, pesticides, herbicides, sediment, rust, unpleasant tastes, and odors while helping prevent mineral scale from forming inside your plumbing and appliances. The included WSP50ARB auto-flushing spin-down prefilter helps capture large debris before it reaches the primary filters, reducing maintenance and extending filter life.
Key Features & Benefits
• Complete Multi-Stage Whole House Filtration – Combines reusable sediment pre-filtration, patented anti-scale media, GAC/KDF filtration, and premium carbon block filtration to deliver cleaner water throughout every faucet, shower, and appliance.
• Broad Contaminant Reduction – Helps reduce PFAS, chlorine, chloramine, lead, mercury, hydrogen sulfide, heavy metals, pesticides, herbicides, sediment, rust, unpleasant tastes, and odors commonly found in residential water supplies.
• Patented Salt-Free Anti-Scale Technology – Specialized polyphosphate media helps prevent calcium and magnesium from forming hard scale while also helping reduce corrosion inside plumbing. This system conditions hardness minerals—it does not remove them like a traditional salt-based water softener.
• Auto-Flushing Spin-Down Sediment Prefilter – The included WSP50ARB uses a reusable 50-micron stainless steel mesh screen with a touch-screen automatic flushing module to capture sand, dirt, rust, silt, and other large particles before they reach the main filters.
• Self-Cleaning Reusable Design – Automatic, semi-automatic, and manual flush modes simplify maintenance while extending the life of downstream filter cartridges and reducing replacement costs.
• 250,000-Gallon Filtration Capacity – High-capacity 20" × 4.5" filter cartridges are designed to provide up to one year of filtration for an average family, depending on incoming water quality and household usage.
• High 15 GPM Flow Rate – Maintains strong water pressure while supplying filtered water to multiple bathrooms, appliances, and fixtures operating simultaneously.
• Protects Plumbing & Household Appliances – Helps minimize sediment, chlorine exposure, corrosion, and mineral scale that can shorten the lifespan of water heaters, dishwashers, washing machines, coffee makers, plumbing fixtures, and other water-using appliances.
• Maintains Beneficial Minerals – Unlike reverse osmosis systems, this whole-house filter preserves naturally occurring minerals and does not reduce Total Dissolved Solids (TDS).
• DIY-Friendly Installation – Standard 1-inch NPT inlet and outlet connections and oversized filter housings simplify installation while minimizing pressure loss across the system.

The iSpring WGB32B-KDS + WSP50ARB is one of the most complete filtration packages available for homeowners who want cleaner water with minimal maintenance. Compared to the standard WSP50 bundle, the WSP50ARB adds an automatic self-cleaning function that significantly reduces manual flushing while protecting the primary filters from heavy sediment. Combined with broad contaminant reduction and salt-free anti-scale protection, it's an excellent choice for homeowners who want cleaner water, longer filter life, and better protection for plumbing and appliances—all without the maintenance of a traditional salt-based water softener.
