WD-D4RF Filter for Waterdrop D4 Reverse Osmosis System, 2-YEAR COMBO

Technology is no longer as complex as it used to be. We adopted innovative technology and design to integrate different filtration materials into a 6-in-1 composite filter after comprehensive research on the properties of various materials. The reverse osmosis water filter uses minimal space to optimize the filtration effect, reducing TDS, chlorine, heavy metals, and more.

This is not a filter that you would have to change often. You need not change it for a whole year, and you would still be assured of excellent performance. The reverse osmosis filter has a 1-year service life, protecting you from water hazards for the entire year.
