About This

  • Filter Compatibility - The Purewell 8-Stage Upgraded Filter is compatible with Purewell SF Series filtration systems as well as ZeroWater pitchers and dispensers. Likewise, ZeroWater filters are also compatible with our filtration system. However, beyond these, our upgraded filters are not compatible with other filtration systems. This filter is not sourced by or sponsored by ZeroWater. Purewell is an independent brand.
  • Upgraded 8-Stage Multi-Functional Filter - This filter combines a pre-filter mesh, three layers of PP cotton, activated carbon, silver ions, KDF, and alkaline materials to remove up to 99.9% of residual chlorine, while effectively blocking rust, sediment, organic compounds and heavy metals. The added alkaline media helps raise pH levels, supporting a more balanced drinking experience. Designed with functionality in mind, this filter offers multiple options to meet different filtration needs.
  • Electricity-Free - This system uses gravity-based filtration and requires no electricity. The Purewell gravity-fed water filter consists of an upper chamber that holds unfiltered tap water and a lower chamber that collects the filtered water. Its power-free operation makes it ideal not only for indoor home use, but also for outdoor settings such as RVs, camping, and travel.
  • Durable and Replaceable - Each upgraded filter provides up to 1,000 gallons of clean drinking water, and the 4-pack provides a total of 4,000 gallons, reducing the need for frequent replacements while meeting your daily hydration needs. The actual lifespan may vary depending on your local water quality. For optimal performance, we recommend replacing the filter every 6 months. The filter is designed for easy, tool-free replacement, making routine maintenance simple and hassle-free.Note: This filter does not reduce TDS levels.
  • Easy Installation & Broad Compatibility - Designed for a leak-free, tool-free installation. Simply twist the filter into your Zero pitcher or dispenser and start filtering instantly—no soaking required. Compatible with models ZR-001, ZR-003, ZR-004, ZR-006, ZR-008, ZR-012, ZR-017, ZR-600, ZP-007RP, ZD-013W, ZD-013D, ZP-010, ZD-010RP, ZD-012RP, ZD-022-RR, ZD-030RP, ZD-018, ZD-20RP, ZJ-003, ZJ-004S, ZBD-040-1, and more.
