Key Features

• 【Advanced 2-in-1 Pre-Filtration】The U01-PP1 composite pre-filter helps capture sand, silt, rust, fine debris, and other insoluble particles before they reach the RO membrane. It conditions the incoming water, supports stable system performance, and helps extend the service life of the RO membrane.
• 【3–6 Month Filter Life】Designed to provide reliable filtration for approximately 3–6 months, depending on source-water quality and daily usage. For consistent water flow and filtration performance, replace the cartridge according to the recommended replacement cycle or when a noticeable decrease in flow occurs.
• 【Tested for Safety and Performance】Designed for use with the Purewell U01 system and independently tested to applicable NSF/ANSI 58 performance requirements. Water-contact materials meet NSF/ANSI 372 lead-free requirements, helping support safe and reliable everyday filtration.
• 【Easy Filter Replacement】The filter features a simple twist-and-lift removal design. To install the new cartridge, align it with the filter port, then rotate and press it down firmly until it is fully seated. No clips or complicated tools are required.
