Overbest NSF Certified Water Filter, Replacement for Pur® Faucet Water Filter, All PUR®, PUR®PLUS Faucet Filtration Systems(Pack of 3)

Overbest faucet water filter is NSF/ANSI 42 certified to help reduce chlorine (up to 97.2%), taste, and odor, and NSF/ANSI 372 certified for lead-free materials. It is designed as a compatible replacement for PUR faucet filtration systems, including PUR Classic, Advanced, and Horizontal faucet mounts (such as PFM100B, PFM450S, FM-3333, FM-9400B, FM-3700B, FM-2000B, FM-9000B, FM-4000B, FM-4100B, FM-2500V, FM-3400B, PFM350V, Pur-0A1, FM-9600, PFM150W, PFM400H, and PFM-270G); it is not sourced by or sponsored by PUR. For best results, replace the filter about every 3 months or 100 gallons, depending on local water conditions. The filter is designed for a precise fit and smooth water flow, and replacement is simple—soak the new filter in clean tap water for 3 minutes, remove the cap, swap the cartridge until it clicks into place, then tighten the cap.
