Puretec CO-SB150-K Balance Plus Twin Undersink Water Filter System for Espresso Equiptment (5,909L Capacity @3.5LPM)

The Puretec CO-SB150-K-LF Balance Plus Twin Undersink Water Filter System is a compact, high-flow filtration solution designed specifically for espresso machines and coffee applications. Built to deliver the ideal balance between flavour enhancement and scale protection, this dual-stage system ensures consistent water quality while extending the life of your coffee equipment.

At the core of the system is Balance+ Technology, which transforms calcium and magnesium hardness into non-adherent crystal structures. This prevents scale build-up inside boilers and components while still retaining the natural minerals essential for proper espresso extraction. Unlike reverse osmosis systems, it does not strip the water, ensuring stable TDS levels, balanced pH, and improved coffee taste.

With a high flow rate of 3.5LPM and a large sediment capacity, the CO-SB150-K-LF is ideal for coffee carts, small cafés, offices, and home baristas looking for a simple and cost-effective filtration solution without compromising performance.
