RadonClear Whole-Home System vs RadonAway RP145: Which Combination Delivers the Best Whole-Home Radon Mitigation?
When it comes to protecting a household from radon gas, the choice between a complete mitigation system like the RadonClear Whole-Home System and a powerful fan unit such as the RadonAway RP145 can be confusing. Both solutions promise effective radon reduction, but they approach the challenge from different angles. This article provides a detailed head-to-head comparison of the RadonClear Whole-Home System versus the RadonAway RP145, helping homeowners decide which combination—or which system alone—delivers the best whole-home radon mitigation for their specific needs.
What Exactly Is the RadonClear Whole-Home System, and How Does It Differ from the RadonAway RP145?
The RadonClear Whole-Home System is a comprehensive, integrated mitigation package that includes a high-performance fan, pre-wired control panel, manometer, exterior venting components, and a sealed sump or sub-slab collection assembly. It is designed as a turnkey solution for typical residential basements and crawl spaces. In contrast, the RadonAway RP145 is a standalone fan unit—the RP145 model is a 144-watt, 4-inch inlet/outlet fan that can be paired with separate piping, caulking, and monitoring equipment. The RadonClear system delivers a complete kit, while the RadonAway RP145 is a component that requires additional purchases for a full installation.
Homeowners should consider the RadonClear Whole-Home System if they want a pre-packaged, ready-to-install solution with guaranteed compatibility. Those who already have some mitigation components or prefer to select each part separately may lean toward the RadonAway RP145. For detailed performance data, see the RadonClear Whole-Home System Mitigation Effectiveness Study: Real-World Results.
Which System Offers Superior Radon Reduction Capabilities: RadonClear Whole-Home System or RadonAway RP145?
Radon reduction effectiveness depends on the fan’s ability to create negative pressure under the slab or in the crawl space. The RadonClear Whole-Home System uses a proprietary fan rated for 180 CFM at 0.5 inches of water column, which is comparable to the RP145’s 144 CFM at 0.5 inches. Below is a direct specification comparison:
| Specification | RadonClear Whole-Home System | RadonAway RP145 |
|---|---|---|
| Fan Type | Integrated centrifugal fan | Standalone RP145 centrifugal fan |
| Maximum CFM at 0.5″ WC | 180 CFM | 144 CFM |
| Power Consumption | 120 W | 144 W |
| Inlet/Outlet Size | 4-inch (standard) | 4-inch |
| Monitoring Included | Manometer and digital display | Manometer not included |
| Warranty | 5-year limited | 5-year limited |
| Kit Price (UK £) | £525 | £280 (fan only) |
The RadonClear Whole-Home System’s slightly higher CFM at 0.5″ WC—180 vs 144—means it can handle slightly larger areas or more restrictive soil conditions. However, both units are tested to reduce radon levels by 90-99% in average homes. The key difference is that the RadonClear system includes all necessary components in one box, ensuring proper sizing and compatibility. The RadonAway RP145 may require additional costs for piping, sealants, and monitoring equipment.

Is the RadonClear Whole-Home System Easier to Install Than the RadonAway RP145?
Installation complexity is a major deciding factor for DIY homeowners or contractors. The RadonClear Whole-Home System is designed for straightforward installation: the kit includes pre-cut piping sections, a detailed instruction manual, all gaskets and clamps, and a pre-wired control panel that connects directly to a standard outlet. Users only need basic tools: a drill, screwdriver, and caulking gun. On average, installation for a standard 2,000-square-foot basement takes 4-6 hours.
The RadonAway RP145, being a fan unit only, requires the installer to source and cut all piping, purchase separate manometers and alarms, and ensure proper sealing of the sub-slab or crawl space membrane. This adds an average of 1-2 hours of preparation time and additional cost. Moreover, compatibility with existing piping can be tricky if the fan’s 4-inch inlet does not match existing ductwork. The RadonClear system eliminates these variables, making it the easier choice for those without extensive HVAC experience.
How Do the Total Costs Compare Between the RadonClear Whole-Home System and the RadonAway RP145?
Initial purchase price is only part of the financial picture. The RadonClear Whole-Home System retails for £525, which includes everything needed for a full installation. In contrast, the RadonAway RP145 fan alone costs £280. However, buyers must add: 20 feet of 4-inch PVC pipe (£40), pipe fittings (£15), a manometer (£30), a digital alarm (£25), exterior vent cap (£20), sealant and fasteners (£15), and electrical wiring components (£10). This brings the RadonAway RP145 total to approximately £435. While still less than the RadonClear system, the difference narrows.
Long-term considerations: The RadonClear system’s warranty covers all components, whereas the RP145 only covers the fan. Replacement of a manometer or alarm on the RP145 setup incurs separate costs. Additionally, the RadonClear system’s energy-efficient fan consumes 120W compared to 144W for the RP145, saving roughly £20 per year on electricity in the UK (based on 0.34p/kWh and 24/7 operation). Over five years, this energy savings offsets the initial price difference. For a full analysis, see the RadonClear Whole-Home System Performance vs Cost: Is It Worth the Investment?
Which System Performs Better in Sub-Slab vs Crawl Space Installations?
Both systems can be configured for sub-slab and crawl space applications, but the RadonClear Whole-Home System offers more flexibility out of the box. The kit includes a large-diameter extraction basin for sub-slab work and a flexible membrane patch kit for crawl spaces. The RadonAway RP145, while suitable for both, requires the installer to purchase separate adaptors or custom-fabricate the collection point.
For sub-slab installations, the RadonClear system’s pre-drilled extraction plate ensures a tight seal under the concrete, avoiding air leaks that reduce effectiveness. In crawl spaces, the included vapor barrier tape and patch work seamlessly with most reinforced polyethylene membranes. The RadonAway RP145 fan, although powerful, may need additional bracketing and ductwork modifications when switching between slab and crawl space setups.
