About this item

• REDUCES CHLORINE, LEAD, MERCURY & VOCs — CLEANER WATER FROM EVERY TAP: This 3 stage whole house water filter system targets chlorine (up to 99%), dissolved lead, mercury, and volatile organic compounds (VOCs) — helping eliminate chemical taste, pool-like odor, and metallic aftertaste in water from every tap.
• INHIBITS SCALE BUILDUP — PROTECTS YOUR WATER HEATER, DISHWASHER & FAUCETS: The WHO32B-KDS whole house water filtration system reduces hard-water scale formation before it reaches your appliances — helping prevent clogged spray arms, cloudy glassware, and reduced efficiency in water heaters and faucets. Users report visibly less white residue and smoother operation after just a few months.
• NO MORE WATER FLOODS OR BACK STRAIN WHEN CHANGING FILTERS: Traditional whole house water filters force you to twist off heavy, water-filled housings — risking spills, leaks, and injury. The WHO series water filters solve it: horizontal housings + built-in drain valves let you safely release pressure and drain water before opening — so you slide cartridges in/out cleanly, confidently, and in under 90 seconds.
• LOGO-ALIGNED TIGHTENING — INSTANT VISUAL CONFIRMATION THAT IT’S SECURE: When the iSpring logo on the housing cap is perfectly parallel to the floor, the cap is fully tightened and the O-ring is properly compressed. Just use the included wrench to secure it — no torque meter needed, no guesswork, and no leaks from under-tightening or over-tightening.
• FREESTANDING STEEL FRAME — NO WALL MOUNTING, NO DRILLING, NO STUDS NEEDED: This whole house water filter stands securely on any level floor — ready for plumbing connection right out of the box. Perfect for garages, basements, utility closets, or other spaces where wall mounting isn’t possible or practical.
• USES UNIVERSAL 20" x 4.5" FILTERS — FULL CONTROL, ZERO LOCK-IN: This whole house water filter system uses standard 20" x 4.5" filters so you can freely choose the right combination for your water quality needs. The compatible replacement pack for this water filtration system is "F3WGB32BKDS" or ASIN "B0BGYK27NZ".
• LASTS UP TO 250,000 GALLONS OR 12 MONTHS — HIGH CAPACITY, LOW MAINTENANCE: This whole home water filtration system delivers full filtration performance for up to 250,000 gallons or 12 months (whichever comes first), with a high-flow capacity of up to 15 GPM and an included 9-inch long-handle wrench for secure, comfortable tightening.
• RETAINS NATURAL MINERALS — NOT A WATER SOFTENER, DOES NOT REDUCE TDS: Unlike reverse osmosis systems, this 3-stage whole house water filter system reduces scale, corrosion, and contaminants while preserving calcium, magnesium, and potassium — protecting appliances without altering water hardness or total dissolved solids. Suitable for both municipal and well water applications.
• LIFETIME U.S.-BASED TECH SUPPORT — REAL PEOPLE, REAL HELP: Backed by iSpring’s lifetime technical support team — all agents are based in Atlanta, GA, trained on WHO series whole house water filter systems, and available via phone, email, or live chat. Includes free access to installation videos, troubleshooting guides, and filter replacement tutorials.
