Experience Crisper Water and Smoother Brews with PureWater Replacement Filters

PureWater Filters delivers a compatible replacement cartridge set designed for Keurig systems, including B150P, K150P, B155P, K155P, K2500, K3000, K3000SE, B3000, B3000SE, K3500, K4000, and Bolt brewing systems. This pack replaces older filter models Q5486, KQ8, and KQ8a, offering a USA-made alternative built to support consistent water quality in your daily coffee and hot beverages.

These cartridges are crafted to support your brewer’s performance by targeting taste and odor concerns directly at the water source. The combination of filtration media works to soften and purify water, helping your machine operate with fewer mineral-related interruptions and preserving flavor integrity so your brews taste cleaner from the first cup to the last.

What this filter helps you achieve

• Removes chlorine and reduces odor, contributing to a fresher-tasting coffee and tea.
• Advanced filtration targets a broad range of tastes and odors, helping you enjoy water that feels cleaner on the palate.
• Polyphosphate scale inhibitor helps mitigate mineral buildup in the brewer’s internal tank, supporting smoother operation over time.

Quality you can trust

Made with granular activated carbon for high surface area adsorption and polypropylene depth filtration for effective taste and odor reduction. The media bed is designed for longevity and reliability, backed by NSF International testing against ANSI/NSF Standard 42 for Taste & Odor Reduction and Chlorine Reduction Class I.

In addition, a NSF-approved polyphosphate additive helps form a protective film to reduce mineral interactions with your equipment, supporting long-term performance. All PureWater Filters products come with a lifetime warranty on parts and dedicated support for installation or troubleshooting questions.

Easy to install and maintain

The filter simply screws into your existing head unit. Replacing the spent media bed is quick—detach the filter body from the head with a twist, swap in the new body, and rethread. This design aims to make routine maintenance straightforward so you can enjoy consistent water quality with minimal downtime.
