Purewell Fluoride-Free 8-Stage Gravity Water Filter System with PC Water Level Window, Certified to Reduce Fluoride, Lead, Total PFAS (Forever Chemicals), Mercury, and Chlorine, SF-FL-2.25G

Filter Compatibility - The Upgraded 8-Stage Fluoride 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.

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 8-Stage Multi-Functional Filter - This upgraded filter is NSF/ANSI 42 certified and features 8-stage technology. It combines a pre-filter mesh, three layers of PP cotton, activated carbon, silver ions, KDF, and fluoride filtration materials to remove up to 99.9% of residual chlorine, reduce fluoride level, and effectively block rust, sediment, organic compounds, and heavy metals. Designed with functionality in mind, this filter offers multiple options to meet different filtration needs.

Up to 90% Fluoride Reduction - The Upgraded 8-Stage Fluoride Filter uses advanced fluoride-removal media—not the commonly used activated alumina, which may pose potential health concerns. Instead, Purewell's high-grade filtration material safely reduces up to 90% of fluoride, offering both effective performance and peace of mind.

Newly Designed Water Level Window - This Purewell stainless steel filtration system features a newly designed transparent water level window. It allows you to monitor the remaining water at a glance—no need to lift the lid or move the upper chamber. Whether you're using it in the kitchen, office, or outdoors, this convenient feature ensures timely refills, eliminates guesswork, and enhances your overall water usage experience.

Durable and Replaceable - Each fluoride filter provides up to 1,000 gallons of clean drinking water, 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.
