About this filter
The Waterdrop WD-G3-N3CB filter is a replacement filter designed for select Waterdrop reverse osmosis systems. It helps keep your under-sink system running smoothly and providing fresh drinking water.
This filter has a rated capacity of 1,100 gallons. It is made to be changed about every 12 months, or sooner if your water flow slows down.
Before you install
Always turn off the cold water supply before you remove the old filter cartridge. Reverse osmosis systems operate under pressure, so shutting off the supply prevents accidental leaks under your sink.
After installing the new cartridge, run water through it before drinking. Follow the flushing instructions printed on the product box. If you are ever unsure about plumbing steps, call a licensed plumber for assistance.
Filter lifespan and ratings
The WD-G3-N3CB filter life is stated as up to 12 months or 1,100 gallons. Your system indicator light tracks time or water use, so change the cartridge when the light signals or when flow drops.
This product is certified by NSF International against NSF/ANSI Standard 58 for the reduction of TDS, and against NSF/ANSI 372 (≤0.25% lead) as stated by Waterdrop page text.
What it fixes
- Replaces an expired filter that has reached up to 12 months or 1,100 gallons of use.

- Helps clear a filter change alert light on your Waterdrop RO system.

How to confirm it fits
- Check the front or side label of your system to confirm it is a Waterdrop G3, G3P600, or G3P800 model.
- Look at your existing filter cartridge to see if it lists part number WD-G3-N3CB.
- Verify if your unit requires a filter that replaces part numbers G3P600 or G3P800.
- Make sure your system is an under-sink reverse osmosis unit with a membrane and a small drain line.
