ProGuard® System Protector

$53.00 Sale

ProGuard® has been formulated to Clean, Protect, and Boost the performance of water softeners, conditioners, and filtration systems.  

Often imitated but never duplicated, ProGuard® is the Gold standard for performance-enhancing cleaners. There are many cheap "resin cleaners" on the market today that can actually damage your system's components, degrade resin capacity, damage activated carbon, or leave stubborn mineral deposits that reduce system efficiency over time.

ProGuard® is the only product endorsed by Crusader Water International to protect your water improvement system, maximize salt/water efficiency, and prolong its usable service life.

ProGuard® retains its potency for 5+ years as long as it is stored in a cold, dark place.
