AQUA CREST Faucet Filter Replacement for All PUR®Plus Water Filter Replacement, PUR® Filter Replacement RF-9999®, NSF 42 Certified, 9-Month, 900-Gallon, 3 Pack

This AQUACREST faucet filter is NSF/ANSI 42 certified to reduce chlorine, taste, and odor and NSF/ANSI 372 certified for lead-free materials; for best start-up, soak the filter in clean tap water for 3 minutes to release trapped air before use. Made with a premium natural coconut activated carbon block, it helps reduce chlorine (up to 97.2%) and can also reduce sediment, large particles, rust, and unpleasant taste and odor based on third-party lab testing (note: it does not reduce TDS). Designed for a strong, steady flow, it’s recommended to replace the filter about every 3 months, depending on local water conditions. This is a replacement for PUR RF-9999 and is compatible with PUR faucet mounts such as PUR Classic, Advanced, and Horizontal Faucet Mounts, including PFM100B, PFM450S, FM-3333, FM-9400B, FM-3700B/FM-3700, FM-2000B, FM-9000B, FM-4000B, FM-4100B, FM-2500V, FM-3400B, PFM350V, Pur-0A1, FM-9600, PFM150W, PFM400H, PFM-270G, PFM800HX, and more; this filter is not sourced by or sponsored by PUR.
