Radon is a serious household threat that often goes under the radar. According to the EPA, this radioactive gas is accountable for about 21,000 lung cancer deaths each year. But the scariest part of all is that you can’t see or smell radon, so you need either a costly contractor or an at-home radon detector to even know it’s there. .

That’s why one of Amazon’s Daily Deals is a literal lifesaver. Airthings Corentium Home Radon Detector—which has more than a thousand five-star reviews—is $40 off today only, and it might be the smartest $99 you can possibly invest in your family’s safety.

Any home can have a radon problem—and thanks to the Airthings at-home radon detector, any homeowner can also fix it. Traditional radon kits take several days to display results—and they often require the homeowner to send results to a lab. This detector cuts out middleman, plus the wait time and fees involved. And all you need is one kit per home, not per room.

Amazon’s best-selling Airthings detector makes determining the levels of radon in your home simple and fast. The battery-operated Corentium Home Radon Detector requires no cords, no outlets, and no assembly—just place the lightweight device anywhere in your home and you’ll see a reading within 24 hours of setup.

Then rest easy knowing this device is on duty 24/7—always displaying up-to-the-minute radon levels, which fluctuate costantly, and keeping you safe even as you sleep. This detector isn’t just amazing—it’s also just $99 today, the lowest we’ve seen it yet, and we’ve had our eye on it for a while.

“Bought this to test radon levels in a property we were thinking of buying,” one reviewer shared. “Also paid a home inspector to test with a top-of-the-line, tamper-proof, calibrated unit. Results came back pretty close, which gave me confidence in this little battery-powered device. The advantage of the Corentium device is that we can now use it for ongoing monitoring. It displays recent radon levels as well as longer-term averages, which is very helpful for monitoring...Costs as much as 2-3 professionally administered tests, so pays for itself if you need multiple tests.”

Another happy shopper said, “I have used this detector and let all my neighbors use it as well. One friend found his levels were 12.67 and now he is putting in a mitigation system. Others show some radon but below 2. Still, they are happy to know where they stand and if they want to install a mitigation system as well. Well worth the peace of mind.”
