The filter provides pure water for up to 528 gallons or 12 months, depending on your water usage and quality. An indicator light will notify you when it’s time for a replacement.

Our 0.0001μm RO membrane and activated carbon layers reduce TDS, nitrate, fluoride, arsenic, lead, and other contaminants. Third-party lab tests confirm its effectiveness.

The Waterdrop reverse osmosis water filter enriches water with beneficial minerals such as Sr²⁺ and H₄SiO₄, ensuring it is both clean and health-supportive. Sr²⁺ helps maintain bone strength and density, reduces bone loss, and may aid in preventing osteoporosis. H₄SiO₄ is essential for collagen formation, a key component of bones, joints, and connective tissues, promoting their flexibility and strength. In addition to supporting health, these minerals can also enhance the flavor of coffee and ingredients in cooking, benefiting both people and pets.

Extremely easy — no tools or plumber required! You can easily replace the filter in just three seconds by simply inserting it.

This filter helps cut plastic waste — equivalent to nearly 4,000 disposable bottles per year — supporting a greener lifestyle.
