Radon · Source-based buying advice
Find the best radon monitor for your daily use. Compare Home 2, View Plus and RD200 by display, history, power and access.
The most useful monitor is the one you can place correctly, read easily and use over time. Start with how you want to check your readings, then compare the complete setup.
For a result from a defined sampling procedure, compare a kit and its laboratory service. For repeated checks and a continuing record, compare a continuous monitor. Use the kit-versus-monitor guide to choose your method.
Plan the measurement period from the test purpose and instructions. The EPA Citizen’s Guide explains US household testing. For a home sale, confirm the required method and report with your provider.

Think about where the monitor will sit, how you’ll access it and which records you’ll want later. If you already own a compatible Airthings hub, include it in the comparison: it can provide Home 2’s path to off-site readings.
Choose the testing room first. Then check the device’s operating conditions and arrange power and connectivity around that position. The basement guide takes you through placement.
For readings from elsewhere in the house or while away, check reception in the actual room after setup. Use the remote-access guide to compare the connection equipment.
Confirm the exact model and US version, seller, included power equipment and connection hardware. Open the model review for setup details, then compare the current retailer offer.
