Not sure where to start?
Step 1: Test First
Don't buy a mitigation system until you know your radon level. A $17 test kit tells you exactly what you're dealing with.
→ Short-Term Test Kit, $17
Step 2: Mitigate
Slab foundation and radon under 15 pCi/L? Start with our Standard Kit. Above 8 pCi/L or difficult sub-slab: go Pro Kit.
→ Standard Kit ($289) or Pro Kit ($369)
Step 3: Verify
After installation, retest with a continuous monitor or a long-term test kit to confirm levels dropped below 4 pCi/L.

⚙️ RadonAway Fan Comparison
| Fan | Price | Max Suction | Flow Rate | Motor | Best For |
|---|---|---|---|---|---|
| XP201 | $134 | 1.7" WC | 30–70 CFM | Standard | Standard slab, radon < 8 pCi/L |
| GX3 Pro | $218 | 3.0" WC | 20–60 CFM | Vapor Tite™ | Clay sub-slab, crawl space, radon 8–15 |
| GX5 Pro | $269 | 5.2" WC | 15–50 CFM | Vapor Tite™ | High radon 15+, large footprint, difficult conditions |
Higher suction = better for dense sub-slab material (clay, fine sand). Higher flow = better for loose gravel or open sub-slab. Most residential jobs need the XP201.
