Polyphosphate (Siliphos) balls are slow-dissolving, food-grade spheres engineered to prevent scale formation and protect against corrosion in residential, commercial, and industrial water systems.
These glass-like crystals gradually release polyphosphate that sequesters calcium, magnesium, and iron ions, keeping them soluble and preventing limescale buildup on pipes, taps, appliances, and boilers while creating a protective film on metal surfaces to reduce rust and brown water staining.
Available in 5 mm, 10 mm, and 20 mm sizes, they suit everything from compact under-sink filters to large whole-house and commercial systems.
With a typical lifespan of 6–12+ months depending on size and flow rate, these balls require no electricity, no salt, and minimal maintenance—simply refill periodically.
Food-grade and safe for potable water, they offer a cost-effective, low-maintenance alternative to water softeners while protecting your entire plumbing system and reducing maintenance costs for heaters and appliances.
