Overview
The Clearsource Ultra is a free-standing, three-stage filtration system designed for installation between a pressurized water source and an RV freshwater connection. Clearsource specifies a 5-micron sediment stage, a 0.5-micron carbon-block stage, and a VirusGuard stage intended to reduce selected bacteria, cysts, viruses, heavy metals, chlorine, and other contaminants.
Clearsource rates the Ultra at approximately 4.5 gallons per minute under its stated test conditions. The system uses a powder-coated metal chassis, stainless-steel connections, and replaceable cartridges. Actual flow and treatment performance depend on supply pressure, water quality, cartridge condition, correct flow direction, and maintenance.

Key Features
- Three-stage filtration using separate sediment, carbon-block, and VirusGuard cartridges.
- First-stage 5-micron filter intended to reduce rust, sediment, and scale-related debris.
- Second-stage 0.5-micron coconut-shell carbon block intended to improve taste and odor and reduce selected chemicals.
- Third-stage VirusGuard filter carries manufacturer claims for reduction of selected bacteria, cysts, viruses, and heavy metals.
- Free-standing metal chassis with stainless-steel fittings and standard RV hose connections.
RV Use Cases
- Campground hookups where sediment, taste, odor, or source variability is a concern.
- Full-time or frequent RV use that justifies a serviceable multi-stage system.
- Owners who want whole-RV filtration before water reaches fixtures and appliances.
- Pressurized freshwater connections with adequate room for an external filter assembly.
Practical Advantages and Limitations
Advantages:
- Separate treatment stages allow sediment and carbon filtration before the final cartridge.
- Large canisters are designed to support useful flow through multiple filtration stages.
- Replaceable standard-size cartridges make routine service visible and trackable.
Considerations:
- The system is larger and heavier than a single inline filter and needs secure storage during travel.
- Replacement cost and service frequency increase with poor source water or heavy use.
- The system must be protected from freezing, impact, contamination, and prolonged outdoor exposure.
- Contaminant-reduction claims depend on the correct cartridges, installation, flow, and replacement intervals.
Best Practices
- Install in the correct direction: Connect the supply to the marked inlet and the RV hose to the outlet.
- Use pressure control: Follow the RV and Clearsource guidance for supply pressure and regulator placement.
- Flush after service: Run water through new cartridges for the manufacturer-specified time before connecting to the RV.
- Check every seal: Inspect canister O-rings, housings, fittings, and hose washers for leakage after pressurizing.
- Track filter life: Base cartridge replacement on usage, water quality, flow changes, and current Clearsource guidance.
- Winterize the assembly: Drain the canisters and store the system where residual water cannot freeze.
Inspector’s Note (RV Pro Solutions Insight)
If you have the storage space and room in the budget to upgrade, I think a multi-stage water filter is a good idea. You’re treating the water coming into the RV, not just the water in one drinking glass. That means filtered water at the kitchen sink, in the shower, and for the other things you do every day while camping.
The Ultra gives you more filtration than a basic inline filter, including stages for sediment and improving taste and odor. Every campground can have a different water supply, and having your own filtration setup can help make the water more consistent from stop to stop. That includes the water going into your traveling companions’ bowls, too. With room for the system and regular cartridge changes, it’s an upgrade that serves the whole RV.
