Everfilt® does not take a catalog approach to our systems. Each system is unique and acutely designed to meet specific conditions. Our quoting process takes into consideration the project itself, the filtration requirements and any obstacles that may arise, in order to provide the appropriate system that will benefit you for years to come.

The Tolson Legacy.
Agriculture, irrigation and farming runs deep throughout the Tolson family legacy. Since the early 1800's, Corona and Riverside, California were home to the Tolson family citrus and dairy farms. During the early 1970's, Brian Tolson the patriarch of the family; would form Tolson Irrigation, during one of the most historic agricultural times in California's history. Decades later and keeping the family legacy strong, he would later become President of Everfilt® Water Filtration Systems, along with son, Vice President Donny Tolson. Designing and installing irrigation systems for commercial and residential projects accelerated a career path that would land him in Cal Poly pursuing an engineering degree. Upon graduating, Brian would later be hired by Mr. Bob Miller, the then owner of Everfilt® Water Filtration Systems and embark on an industry defining career in water filtration.

As an engineer for over 30 years, Brian Tolson was afforded the opportunity to take over Everfilt® as the sole owner, along with Donny Tolson presiding as Vice President. What started years ago as a father and son working together in the farming and irrigation business, resulted in an opportunity to bring their combined experience and expertise to run one of the industries pioneering water filtration businesses. In 2019 Brian passed away, leaving Donny Tolson as sole owner, continuing to maintain and advance the legacy that was started over 100 years ago. Our family roots run deep and will continue to grow for years to come. This is Everfilt® Water Filtration Systems and we're here to stay!
