FilterBalls™ is the ONLY media that gives you crystal clear water and super high efficiency while running 24/7 and following the Department of Energy regulations in force for 2021. FilterBalls is a lightweight high performance filtration media, engineered to replace sand in your residential pool, industrial, or commercial “sand type” filter systems. No more aggravation and mess, just a one cubic foot bag of FilterBalls media replaces and outperforms 100 pounds of sand. Most residential filters require less than 5 pounds of FilterBalls!
FilterBalls are Made in the USA, are fully recyclable, and certified to NSF/ANSI 50 for use in commercial and public pools and the NSF/ANSI certifications 42, 61 and 372 for drinking water health and safety.
Look for the MADE IN THE USA mark. Don’t be fooled by cheap imported imitations that at times have the name Filter Balls.
