Radon

You can't see or smell it, but long-term exposure to this radioactive gas is the top cause of lung cancer in non-smokers.

Temperature

Temperature is not just a matter of comfort, it can negatively affect sleep quality, mood, and alertness.

Humidity

High humidity promotes mold growth and aggravates asthma symptoms, while too-dry air can lead to skin and throat irritation.

Don’t stay in the dark, see radon clearly.

The most trusted digital radon detector in the world.
Now even smarter. Meet Corentium Home 2.

Why measure radon?

You work hard to create a safe and happy home, but radon could be silently putting you and your family at risk.

Radon is a naturally occurring, invisible gas that comes from the ground. It can enter any home through cracks, floors, or foundations without any smell or warning.

That makes radon a silent and invisible threat.

How radon affects your health

According to the U.S. Environmental Protection Agency (EPA), radon is the second leading cause of lung cancer, right after smoking.

Living with high radon levels can be as harmful as smoking 10 cigarettes a day without even knowing it.

Safeguard your future

Each home is unique when it comes to radon levels, so even neighboring houses can have very different readings. The only way to know your home’s radon level is to test.

The EPA recommends testing for radon when buying or selling a home and, if necessary, lowering the radon levels. Document all test results and any mitigation taken, as these can be valuable assets to have.

Corentium Home 2

the smart, effortless way to protect your home from the invisible threat of radon.

Every home should measure radon.

Not knowing is hard. Testing is easy.

In 2011, Airthings revolutionized home radon detection with Corentium Home, setting the benchmark for reliable, continuous monitoring.

Corentium Home 2 offers the same trusted accuracy with the added advantage of smart connectivity with the Airthings app.

Why track humidity and temperature?

Since radon is often measured in basements and lower floors, Corentium Home 2 now also includes temperature and humidity sensors.

These are common issues in these spaces, and understanding whether the space is particularly damp or cold can help you take action to prevent mold, moisture damage, and discomfort.

Frequently asked questions

What is a "rolling average"?

A rolling average shows trends by averaging data over time. The 7-day rolling average updates daily, including the newest day's data while removing the oldest. Higher rolling averages than your long-term average indicate increasing radon levels; lower averages indicate decreasing levels.

How long should I measure for radon?

Measure for several weeks since radon levels fluctuate constantly. For best results, measure during colder seasons and consult local authorities for guidance.

With a mitigation system installed, continuous monitoring helps verify it's working properly and alerts you to any issues.

Can I use the detector without the Airthings app?

Yes, you can. However, the free app provides historical data graphs and personalized insights to help you understand your radon levels.

Why wait 24 hours for first radon values?

Radon levels vary significantly throughout the day, so we use 24-hour averages instead of individual readings for greater accuracy. Your first average will appear after one full day of data collection.
