Purewell PB-2 Black Replacement Filters for ProOne® and Berkey® Filters (2 Pack)

About this item

• [Extended Lifespan] Each pair of carbon composite filters provides up to 6,000 gallons of fresh water. For optimal performance, we recommend replacing the filter every 6,000 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.
• [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 99.9% 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.
• [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.
