A Legacy of Purity and Performance
Our journey began with a mission: to improve water quality through dependable purification technology. Over the past three decades, we’ve refined our systems, integrated new advancements, and continuously prioritized performance and customer satisfaction. We understand that water purification is not a one-size-fits-all service, which is why every Coster system is engineered for the specific demands of the application and environment in which it will be used.
Whether you’re operating a single retail outlet or overseeing a multi-location business, you can count on our team to provide the right configuration, the right components, and the right support. Every detail matters when it comes to water purity—and at Coster, every detail is handled with care.

Advanced Water Purification Technology
One of the core technologies behind our systems is Reverse Osmosis (RO). This method pushes water through a semi-permeable membrane under pressure, effectively removing a wide range of contaminants—including dissolved salts, bacteria, particles, and organic substances. The result is water that is not only clean and safe but also consistent in taste and quality.
Reverse Osmosis is just one of the technologies we use. Our systems may also include activated carbon filtration, ultraviolet (UV) disinfection, sediment filtration, and more—depending on your specific needs. Each unit is engineered for maximum performance, longevity, and minimal maintenance.
