PROTECTION AGAINST VIRUSES, BACTERIA, AND CYSTSThe top-of-the-line Clearsource Ultra Water Filter System with exclusive VirusGuard filters uses NASA-developed technology to remove or reduce bacteria, cysts, and viruses. No other RV water filter on the market provides anything close to that level of protection. THREE-STAGE FILTERINGWhen your water leaves the Ultra Water Filter System, it has been filtered three separate times. A 5-micron first-stage filter removes or reduces rust and sediment. The 0.5-micron second-stage coconut shell carbon block filter improves taste and smell and removes or reduces chlorine, volatile organic compounds, and other contaminants. Clearsource's third stage VirusGuard filter provides even better protection than advanced survival filters, with the certified capability to remove or reduce bacteria like e. coli, cysts like Giardia, and â unique to Clearsource â viruses. BULLET-PROOF CONSTRUCTIONThe Ultra System is built with a rugged, industry-exclusive powder-coated metal chassis for easy setup between your water source and the freshwater connection on your rig.
