- [Compatible Models] The Purewell 3-Stage Composite Filters can be replacement for ProOne Big+ or Big II Series and Berkey BB9-2 black filters, Travel, Big, Royal, Imperial, Light, Crown Berkey Series. It serves as the original filter for the Purewell gravity water filtration system. Thanks to its exquisite design, this filter achieves great fit and no leakage. The water filter is not sourced by or sponsored by Berkey or ProOne. Purewell is an independent brand.
- [Advanced 3-Stage Filtration] Our composite filter is certified to NSF/ANSI 42, featuring a high-performance, 3-stage filtration technology. It combines a 0.01μm hollow fiber UF membrane, silver ion barrier, and high-density activated carbon block, providing up to 99.9% removal efficiency for chlorine, rust, sediment, organic compounds, and heavy metals. Additionally, the filter meets NSF/ANSI 372 standards for lead-free materials, ensuring safe and reliable filtration for daily use.
- [Technical Innovation] Exceptional Small Pore Size - Purewell’s filtration elements feature an ultra-fine pore size of 0.01 microns, a significant improvement over the typical 0.2 microns found in other brands. This smaller pore size effectively removes 99.99% of contaminants, including ultra-fine particles, thus greatly reducing potential health risks. A finer pore size means greater filtration precision, providing you with cleaner and safer drinking water.
- [Extended Lifespan] Each set of 4 carbon composite filters provides up to 12,000 gallons of fresh water. For optimal performance, we recommend replacing the filter every 12,000 gallons, though this may vary based on your water quality. Note: TDS levels do not fully indicate water quality, and our filters are not designed to lower TDS levels.
- [Risk-free Purchase] For optimal filtration, please follow the pre-filtration instructions in the manual before installing the filter. If you experience clogging, slow flow, unusual odors, or compatibility issues, please contact us immediately for a free, quick replacement service.
