Spectrapure Silica-Buster Mixed-Bed Multi-Layer DI Cartridge
Sold Out - $ 32.99
SpectraPure SilicaBuster Mixed-Bed Multi-Layer Deionization Cartridges are fabricated with semi-conductor grade resins for highest possible purity. They are capable of producing 18 megohm-cm resistivity water. They are the first deionization cartridges designed to reduce silica, nitrates and phosphate levels in the low ppb range. These newly formulated cartridges far exceed the performance of previous cartridges, offering enhanced contaminant removal, longer life and higher purity.
Caution: The deionization cartridge life is greatly reduced when operated on low pH waters or water with high CO2 (carbon dioxide) levels. The exact cartridge life will vary greatly with pH, carbon dioxide levels and TDS etc. in your RO water or the feed water supplying the RO system. Aeration or degassification of RO product water is recommended for such waters for removal of carbon dioxide.
- Removes all heavy metals and cationic impurities
- Regenerable with hydrochloric acid for reuse
