Elevate your tap water with iSpring F3WCB32-O filters

Designed to safeguard your family and household appliances from chlorine, chloramine, PFAS, and other chemicals, the iSpring F3WCB32-O set combines three filtration stages in a single 20 x 2.5 inch cartridge trio. Compatible with iSpring RCB3P and WCB32C systems, as well as standard housings, these cartridges are built for everyday use in kitchens, laundry rooms, and drinking water stations.

How the filtration works

  • Stage 1: a polypropylene sediment filter removes particles as small as 5 microns, helping to protect downstream stages and appliances.
  • Stage 2: a GAC (granular activated carbon) layer reduces tastes and odors tied to chlorine and other compounds.
  • Stage 3: a CTO carbon block crafted from coconut shell carbon delivers high-efficiency chlorine reduction, contributing to crisper water.

Independent testing confirms performance against NSF/ANSI standards, with each cartridge rated for up to 30,000 gallons under typical use. The system delivers a steady flow of water—up to 12 gallons per minute—so day-to-day tasks from coffee to cooking stay uninterrupted.

Quality, freshness, and after-sale support

  • Each cartridge is individually wrapped to maintain freshness; unwrap before replacement to ensure optimal performance.
  • Replacement guidance is available via the included manual and step-by-step YouTube videos for a straightforward swap.
  • Customer support from iSpring’s Atlanta, GA headquarters is available by phone or email for questions or guidance.

Important note: these filters do not reduce Total Dissolved Solids (TDS); they preserve healthy minerals while focusing on chemical reduction and particle removal. If you’re seeking TDS removal, consider iSpring RO systems designed for that purpose.
