This Old House Ecosense Radon Monitor: Why Continuous Monitoring Matters
We’re proud to announce that This Old House spotlighted the Ecosense EcoQube Radon Monitor as a trusted solution for continuous radon monitoring. In the "How To Reduce Radon" episode, experts followed a homeowner who inherited his grandparents’ house and worried about radon after learning their dog had died from lung cancer, a rare illness in pets. Since no one in the family smokes, and with neighbors already installing mitigation systems, he wanted real answers.
Case Study: This Old House EcoQube Radon Monitor in Action
To understand the radon levels in his home, the homeowner set up the Ecosense EcoQube Radon Monitor for three months before taking any action. The data was eye-opening:
-
A 3-month average of 12.7 pCi/L — more than three times the EPA’s action level of 4 pCi/L.
-
Radon fluctuations ranging from 3 pCi/L up to 15 pCi/L in just 24 hours.

The EcoQube mobile app’s historic trend chart made these fluctuations clear, showing that radon is far from static.
Although the daily average was around 12, the graph is so detailed. It shows exactly how radon fluctuates during the day. The This Old House host emphasized how valuable this level of detail was:
People think radon levels are static. You do a short-term test and that’s it. But this is why we stress continuous monitoring because it’s very dynamic, it’s always changing.”
By using EcoQube, the homeowner didn’t just get a snapshot; he gained a detailed, long-term understanding of how radon levels changed in his basement, down to updates every 10 minutes. The show's experts stressed radon monitoring must be continuous, not a one-time test.

Post-Mitigation: Monitoring for Life
After a mitigation system was installed, the experts returned to EcoQube’s role:
“What’s great is that you already have a continuous radon monitor. Just leave it in place, so you have updates every 10 minutes — forever.”
While retesting every two years is still recommended, the homeowner’s EcoQube now provides ongoing peace of mind with continuous tracking.

The Takeaway
The episode highlighted why continuous radon monitoring is crucial both before and after mitigation.
As This Old House explained in their blog on reducing radon:
“Continuous monitoring is a much better baseline than simply taking spot readings. Radon levels in a home can fluctuate considerably throughout the day… safe levels in the morning may become elevated at other points throughout the day, so continuous monitoring is a must.”
The This Old House Ecosense Radon Monitor feature underscores a simple truth:
-
One-time radon tests aren’t enough; they can miss dangerous spikes.
-
Continuous monitoring delivers the full picture of radon behavior, before and after mitigation.
-
EcoQube makes it effortless, so families, children, and pets stay protected every day of the year.
