⭐ Key Features

•【Compatible Models】 Purewell upgraded composite filter is a direct drop-in replacement for ProOne Big+/Big II Series and Berkey BB9-2 black filters, as well as Berkey Travel, Big, Royal, Imperial, Light and Crown Series. It is also fully compatible with Purewell Gravity-fed Water Filter System, featuring a precision-engineered tight seal for secure fit and reliable installation. Note: This filter is not affiliated with, sourced by or sponsored by Berkey or ProOne; Purewell is an independent professional water purification brand.

•【Advanced 4-Stage Filtration】 NSF/ANSI 42 certified, our premium composite filter features a high-performance 4-stage filtration structure, integrating a 0.01μm hollow fiber ultrafiltration membrane, professional alkaline materials, silver ion barrier, and high-density activated carbon block. This multi-layer design removes up to 99.9% of chlorine, rust, sediment, organic compounds and heavy metals, while alkalizing the water. Compliant with NSF/ANSI 372 lead-free standards, it ensures reliable filtration for daily family drinking.

•[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.

•【Long-Lasting Filtration】 Each single filter delivers up to 3,000 gallons of fresh, purified water, and a pair provides up to 6,000 gallons total, giving your household reliable, long-lasting performance. For optimal filtration, we recommend replacing the filter at the 3,000-gallon mark per single unit, though frequency may vary with your actual water quality. Note: TDS levels do not fully indicate water quality, and our filters are not designed to lower TDS levels.

•【Eco-Friendly & Cost-Effective Hydration Solution】 Each Purewell replacement filter helps eliminate thousands of single-use plastic bottles, reducing plastic waste while significantly cutting long-term bottled water expenses. This sustainable design combines high-performance purification with eco-friendly living, supporting a greener low-waste lifestyle and delivering consistent, high-quality drinking water for the whole family.
