- [Next-Level Filtration Performance] Purewell's upgraded black filter PF-1 takes water purification to a whole new level. With a 0.83-inch thick wall, nearly 50% thicker than other brands, it maximizes water contact for superior filtration efficiency. Plus, the 0.01-micron ultra-fine pore size, which is 20 times smaller than the standard 0.2 microns, removes 99.9% of harmful contaminants, ensuring purer, healthier, and safer drinking water for you and your family.
- [Advanced 4-Stage Filtration] Certified by NSF/ANSI 42, our composite filter features advanced 4-stage filtration technology, including a 0.01μm hollow fiber ultrafiltration membrane, alkaline materials, a silver ion barrier and high-density activated carbon block. This powerful system removes 99.9% of chlorine, rust, sediment, organic compounds and heavy metals, while alkalizing the water. Compliant with NSF/ANSI 372 lead-free standards, it guarantees safe and reliable filtration for daily use.
- [Enjoy Healthy Alkaline Water] This upgraded composite filter is meticulously designed to raise the pH level of tap water, promoting overall health, accelerating detoxification, and enhancing bone and digestive health.
- [Nearly Double the Lifespan] Each pair of upgraded composite filters can provide up to 10,000 gallons of fresh water, which is 4,000 gallons more than the standard 6,000-gallon lifespan of most filters on the market. This allows one household to reduce up to 80,000 plastic bottles (500ml) within 3 years, contributing to a more sustainable and eco-friendly lifestyle. Note: TDS levels do not fully reflect water quality, and our filters are not designed to reduce TDS levels.
- [Compatible Models] The Upgraded 4-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.
