It may not be COVID but the air in your home could make you sick

A professional can test for radon levels and other air pollutants in your home, or you can do it yourself with a detection system

You may think you’re doing your duty to help flatten the COVID-19 infection curve but staying home may expose your family to different types of health risks.

No, the culprit isn’t bacteria or a virus. It’s the quality of the air we breathe in our homes and the contaminants lurking within. It may be an excess of carbon dioxide (CO2) impairing restfulness. Perhaps it’s volatile organic compounds (VOCs) from cooking, paints and cosmetics causing nose and throat irritations. Or it could also be something as simple as an imbalance of air pressure or humidity causing discomfort.

But it may be even more concerning. No, it’s not carbon monoxide, which can impact you instantly – it could even be radon gas. Unbeknownst to many, it’s the second leading cause of lung cancer after smoking, according to Health Canada. Smokers are at even higher risk.

Radon is everywhere. It doesn’t matter where you live – a new house or a century old – every home has some level of radon and that level determines the health hazard.

What is Radon, Anyway?

Radon is produced naturally by the decomposition of uranium in the soil under your home. This invisible odourless gas seeps into your home due to the differences in indoor and outdoor air pressure. It sneaks in through openings like floor drains and sump pumps, foundation and floor cracks, and tiny gaps around pipes entering the home.

As a result, it’s more likely to be concentrated in basements and crawl spaces than upper areas of your home.

Don’t Panic Yet!

Don’t hit the panic button just yet. Unlike deadly carbon monoxide or fumes from a fire that attack quickly, radon is only hazardous over time – and you can do something about it.

A professional can test for radon levels and other air pollutants in your home, or you can do it yourself with a detection system like Wave Plus by Airthings. Some public libraries even have radon detection kits.

Wave Plus, Real Results

Wave Plus is a smart indoor air quality plus radon detector that looks like and installs just as easily as a smoke detector. It has six sensors measuring some of the causes like radon, VOCsCO2humidity, air pressure and temperature. You can see your initial test results within an hour by simply waving your hand across its face – thus the name.

If measurements are within acceptable levels, the glow ring will turn green like a traffic light. Yellow says caution and red indicates you’re in the danger zone.

According to Health Canada, the acceptable standard for radon is 200 Bq/m3 (becquerels per cubic metre). One becquerel equals one radon atom disintegration per second.

Use the app plus web-based dashboard for detailed tracking and downloading data

The beauty of the Wave Plus system is that you get real results from the companion app. You don’t have to send the data to a lab for analysis. You simply pair it with your iOS or Android smartphone or tablet and it will keep track of the radon levels, as well as the five others measured.

In addition to tracking current values, you can plot a graph that covers the previous 48 hours, week, month or year.

The app is designed to track multiple units in your home.

You can receive notifications though the app, as well as sync information when you’re within Bluetooth range. You can also receive email and audio alerts when the radon levels become too high. An optional $99 hub is available to further tie all your devices together and monitor your home remotely 24/7.

Since radon and other levels are always fluctuating, the longer the test period, the more accurate your results. Health Canada recommends that homes be tested for radon for a minimum of three months, ideally during the heating season when windows are typically closed.

Airthings also has a web-based dashboard to help with your tracking. It offers a more detailed look over time. You can also create customized reports and download your data should you need further analysis.

Should levels consistently read high, call in a professional to determine what remedial action is needed. There could also be other contaminants like mold also lurking behind the walls – but there are other detection devices for that.

Wave Plus comes with a magnetic plate that mounts on a wall with a single screw. The unit is powered by two standard AA batteries (included) that should last up to 18 months. It retails for $299.99 and makes for a great family holiday gift.  You can find it BestBuy, Home Depot or Amazon. Other models/configurations are also available.
