Housing & Application Requirements

Poly Guard Crystals are designed to be used with Pro Products' patented refillable polyphosphate cartridge, which fits standard 10-inch whole house filter housings. The crystals do not dissolve completely and require periodic replacement to maintain efficacy. This system is ideal for well water applications, tankless water heaters, boilers, and any plumbing system experiencing hard water scale or iron staining issues.

🔧 Pro Tip: The crystals will not fully dissolve during normal use. Replace them based on gallons treated or every six months, even if crystals remain visible in the cartridge, to ensure continued protection against scale formation.
