Clearsource Ultra OnBoard Pro RV Water Filter System


Purpose-built for the RVer, the Clearsource OnBoard Pro RV water filter delivers better water and better water flow. 

The custom-fabricated powder-coated metal chassis with pre-drilled mounting holes lets you mount the system onboard, in the utility bay, or anywhere else you would like. And our quality PEX fittings keep things sanitary, and stand up to years of abuse.

We build our top-of-the-line 3 canister systems with new, Clearsource-exclusive VirusGuard ™ filters that use NASA-developed technology to remove or reduce not just bacteria and cysts, but viruses. No other RV water filter on the market provides anything close to that level of protection.

THREE STAGE FILTERING. When your water leaves our OnBoard Pro water filter system, it has been filtered three separate times. Our 5-micron first stage filter removes or reduces rust and sediment. Our 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. Our 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 – unique to Clearsource - viruses.

Filters included.
