Quick install
1. Open the upper chamber and unscrew the old cartridges.
2. Soak the new cartridges in clean water for 30 minutes; tilt to release air bubbles.
3. Rinse briefly, then screw the cartridges into place.
4. Reassemble the chamber and run a full flush cycle before drinking.
The filter targets trihalomethanes, chloramine, inorganic minerals and a host of other pollutants—including arsenic, petroleum residues and unpleasant odors—providing safer water for cooking, brewing coffee or filling a baby bottle. This non‑OEM pack offers a cost‑effective upgrade while maintaining the same performance standards as the original Doulton filter.
