Waterdrop Faucet Filter Replacement Cartridge RF-9999 Compatible 1-Pack — NSF Certified Chlorine & Taste Reduction

Waterdrop's compatible faucet filter replacement delivers cleaner-tasting tap water by reducing chlorine, bad tastes and odors while fitting many PUR faucet mount models.

This Waterdrop replacement cartridge is designed as a drop-in substitute for common PUR faucet filters, giving you filtered water straight from the tap without changing your faucet hardware. It is independently certified by NSF to meet standards for chlorine, taste and odor reduction and is built from lead-free materials. The cartridge is intended for use with PUR Advanced and Advanced Plus faucet mounts and many PUR model numbers listed for compatibility.

How long will one filter last before I need to change it?

Each cartridge is engineered to provide up to about three months of typical household use, depending on your water quality and daily consumption. Replace it sooner if you notice reduced flow or a return of taste or odor.

• Expected life: ~3 months under normal usage
• Signs to replace: diminished flow, altered taste, or odor
• Simple swap: designed for quick cartridge replacement

Which faucet mounts and PUR models does this fit?

The Waterdrop replacement is compatible with a wide range of PUR faucet-mounted systems and is interchangeable with PUR RF-9999 style cartridges. Manufacturer model numbers are provided for reference; this is an independent Waterdrop product engineered to match those fitments.

• Works with PUR Advanced and Advanced Plus faucet mounts
• Interchangeable with RF-9999 and many PUR model numbers

What contaminants does the cartridge reduce, and what won't it remove?

This cartridge is tested to NSF/ANSI 42 for reducing chlorine, taste and odor and is made from NSF/ANSI 372-compliant lead-free materials. It improves drinking water flavor and clarity but is not formulated to lower total dissolved solids (TDS) or act as a multi-stage contaminant removal system.

• Reduces: chlorine, unpleasant tastes and odors
• Certified: NSF/ANSI 42 and NSF/ANSI 372 for lead-free materials
• Not designed to reduce: TDS or all chemical contaminants

How easy is installation and what performance can I expect?

• Tool-free swap: fits existing PUR-style faucet mounts
• Maintains smooth flow by trapping sediment and particles
• Consistent flavor improvement until replacement is due
