Purewell is an independent brand.
• 【NSF-Certified 8-Stage Filtration】The Purewell Purification Elements Set is certified to NSF/ANSI 42, featuring a high-performance, 8-stage filtration technology. The outer layer of the ceramic filter element is made of pure natural ceramic material, and the inner layer contains silver ion membrane and activated carbon block to reduce rust. The Fluoride Filter uses a fluoride reduction membrane, an activated carbon block, and three sediment PP membranes to intercept fluoride and chlorine.
• 【90% Fluoride Reduction】The Purewell Fluoride Filter is made from advanced fluoride removal material. Unlike traditional alumina-based filters (which can pose health risks), our fluoride filter uses a safer, more advanced filtration media to remove up to 90% of fluoride. Plus, it's NSF/ANSI 372 lead-free certified, so you never have to worry about harmful leaks or contaminants.
• 【Safe and Washable】The replacement for Berlkey or ProOne water filter is certified against NSF/ANSI 372 standard for lead-free materials. Furthermore, The ceramic filters uses BPA-free housing, ensuring its safety. When sedimentation appear on the surface of the filter element, you can use the included sponge to scrub the surface of the filter element to extend the service life of the filter element, but do not use soap or other cleaning materials (otherwise it will clog/damage the filter pores).
• 【Longer Service Life】Ceramic and Fluoride filters provide up to 20,000 and 2,000 gallons of drinking water, respectively. (Filter lifespan may vary slightly depending on water quality). For optimal performance under normal conditions, replace the PF-4 Ceramic Filter every 10,000 gallons and the FL-2 Fluoride Filter every 1,000 gallons. Note: The TDS level does not fully indicate the quality of the water and our filters DOES NOT lower TDS value.
