About Harmsco

Driven by innovation and built on decades of engineering expertise, Harmsco designs high-performance industrial filtration systems trusted across industries worldwide.

Founded in 1958 in West Palm Beach, Florida, Harmsco began with a simple mission: to engineer better, longer-lasting filters. From hand-crafted stainless-steel pool filters to advanced industrial filtration solutions, the Harmsco name has become synonymous with quality, durability, and performance in liquid filtration technology.

John F. Harms pioneered the first pleated polyester filter cartridges—an industry-changing advancement that continues to define Harmsco’s superior filtration efficiency and cost savings. Under the leadership of Harold “Hank” Harms II, the company expanded into commercial, industrial, and municipal water treatment markets, introducing the acclaimed Hurricane® XP filtration systems and broadening its reach worldwide, with the largest selection of replacement filter cartridges in the world.

Now led by the third generation, Harmsco remains a family-owned American manufacturer dedicated to engineering excellence, reliability, and customer satisfaction. With state-of-the-art manufacturing facilities in Florida and a global distribution network, Harmsco continues to develop innovative filtration technologies that meet the toughest water quality and liquid process challenges delivering cleaner, safer, and more efficient results for industries everywhere.
