About This Filter Compatibility - The Upgraded 7-Stage TDS Filter is compatible with Purewell SF Series filtration systems as well as Zero pitchers and dispensers. However, beyond these, our upgraded filters are not compatible with other filtration systems. This filter is not sourced by or sponsored by Zero. Purewell is an independent brand. Achieve 0 TDS - The only stainless steel gravity-fed filtration system capable of reducing Total Dissolved Solids(TDS) to zero. It effectively removes calcium, magnesium, and other dissolved solids from tap water, delivering ultra-pure, healthier drinking water. Unlike reverse osmosis systems, it requires no complicated setup—just a simple twist-in filter. NSF/ANSI 53 & 42 & 372 certified for trusted performance. Certified to Reduce Lead & Total PFAS - Our water filter dispenser is IAPMO certified to reduce Total PFAS (forever chemicals), lead, chlorine, mercury, and many other harmful contaminants. This rigorous certification ensures every sip is cleaner, safer, and better tasting, helping protect your health and giving you peace of mind with every pour. Upgraded 7-Stage Multi-Functional Filter - This filter combines a pre-filter mesh, three layers of PP cotton, activated carbon, silver ions, KDF, and TDS reduction media to remove up to 99.9% of residual chlorine, while effectively blocking rust, sediment, organic compounds and heavy metals. The added TDS reduction layer helps lower total dissolved solids for cleaner, purer-tasting water. Designed with functionality in mind, this filter offers multiple options to meet different filtration needs. 4X Longer Lifespan - Each TDS filter delivers up to 100 gallons of clean drinking water and contains over 4 times more filtration media than replacement filters from Zero and other brands—resulting in a lifespan that's more than 4 times longer. It supports your daily hydration needs while reducing the hassle of frequent replacements. However, actual lifespan may vary depending on your local water quality. For optimal performance, we recommend replacing the filter every month. 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.
