Our service team handles everything from expert, seamless installation to regular maintenance, backed by C-Sense smart monitoring that alerts our team in real-time when your system needs attention.
What happened to the Quench Q3 and Q4 water coolers?
The Quench Q3 and Q4 have been discontinued and our Purity Essential is the recommended successor. Compared to our legacy machines, Culligan Purity offers an elevated design and user experience. With an intuitive touchscreen for easy dispensing and Culligan Quench advanced filtration technology, the Purity Essential ensures reliable performance.
Is the Purity Essential the replacement for the Quench Q3 and Q4?
The Purity Essential is a natural upgrade for customers who were originally interested in our Q3 and Q4 solutions. The product maintains the familiar easy-install format while introducing upgraded multi-stage filtration and continued Culligan Quench service support.
How does the Purity Essential filter water?
Purity Essential offers two main water filtration solutions—Carbon Filtration and Reverse Osmosis—each available in multiple packages designed to reduce contaminants, microplastics, and forever chemicals (PFAS) with varying levels of effectiveness. Reverse Osmosis systems provide the most advanced purification, while both solutions can be enhanced with remineralization filters to restore essential minerals like calcium and magnesium for improved taste and wellness benefits.
How is the Purity Essential installed, and does it require a plumber?
The Purity Essential is a plumbed appliance that connects directly to your existing water supply line, just like other office water solutions. Our local Culligan Quench service professionals handle the complete installation process, so you don’t need to coordinate or hire a separate plumber. Once installed, you’ll enjoy the convenience of on-demand hot and cold filtered water without the hassle of managing bottle deliveries, storage space, or the physical burden of lifting heavy water jugs.
