iSpring WHO32B-KS Free-Standing Whole House Water Filter System — Open-Box, 16% Off

POWERFUL PROTECTION AGAINST HEAVY METALS, CHLORINE & SEDIMENTS: Equipped with high-capacity 20" x 4.5" jumbo cartridges, this whole house water filtering system helps reduce chlorine, sediment, lead, mercury, hydrogen sulfide, chloramine, odors, rust, VOCs, and 1000+ contaminants while maintaining strong water flow up to 15 GPM for homes and light commercial use. Long-lasting filtration delivers clean water for up to 12 months or 150,000 gallons, depending on water quality and usage.

EASY FILTER CHANGES — NO MORE HEAVY HOUSINGS OR WATER MESS: Traditional whole house water filter systems require twisting off heavy filter housings filled with water — causing spills, strain, and frustration. The iSpring WHO Series features an innovative horizontal housing design with built-in drain valves, allowing you to release pressure and drain water before replacing filters. Simply slide cartridges in and out with less lifting, less mess, and less hassle.

BUILT-IN SEAL MARK — KNOW IT’S TIGHTENED CORRECTLY: No more guessing if the housing cap is fully sealed. The housing logo aligns horizontally when properly tightened, helping prevent overtightening, damaged O-rings, leaks, and difficult future maintenance. Easier for homeowners, safer for long-term use.

USES INDUSTRY-STANDARD 20" x 4.5" FILTERS — NO PROPRIETARY LOCK-IN: Unlike systems requiring expensive brand-specific cartridges, the WHO Series whole house water filtration systems use universal industry-standard filters that are widely available and easy to replace. Freely customize filtration stages based on your water needs while enjoying lower long-term maintenance costs. For compatible replacement filter packs, search “F3WGB32BKS” or “B08HPG7K3X”.

FREESTANDING METAL FRAME — NO WALL MOUNTING REQUIRED: The heavy-duty freestanding bracket allows flexible floor placement without needing to mount the whole house system onto walls. Designed for easier installation and maintenance access in garages, basements, utility rooms, and tight spaces.
