• ‌Faucet Compatibility: Designed for faucets with 1/2" or 3/8" female threads. If you need a female threaded connector to attach to your faucet, please contact us before purchase.
• Replacement Value: Each WD-RF17 replacement filter is priced under $44.99, and is described as helping reduce ongoing replacement costs by over 50% compared with many alternatives.
• Service Life & Storage Tip: When used with municipal water, each under-sink filter is rated for up to 36 months or 24,000 gallons, with actual life varying by local water conditions. Before vacations, place filters in sealed bags and store in the refrigerator (not the freezer) for up to 30 days.
• Filtration Performance & Testing: IAPMO tested to NSF/ANSI 42 for reduction of chlorine, taste, and odor. Additional testing reports indicate reduction of VOC-related compounds (including chloroform, benzene, chlorobenzene, chloropicrin, and styrene), removal of sediment and rust, third-party testing to NSF/ANSI 53 for lead reduction, and reduction of PFAS (including PFOA/PFOS). An upgraded filtration area is described as providing about 20× more dirt-adhesion area to help improve performance while lowering the risk of clogging.
• Certified Materials & Easy Installation: Made with BPA-free and lead-free materials and IAPMO certified to NSF/ANSI 372 (lead-free materials). Certification details can be reviewed by searching “WD-17UA” on the IAPMO website. Designed for cold water only and installs with push-to-connect fittings in about 3 minutes; the twist-and-lock design supports filter changes in about 3 seconds. Includes a direct-connect 3/8" hose for standard under-sink feed valves and a 3/8"–1/2" converter for common cold-water lines and faucets.
