Airthings Wave Plus Review


If you want to monitor your house for radon levels (and you should do it if you live in a high concentration area), Airthings Wave Plus is a simple and effective way to do it. This battery powered monitor can also detect harmful chemicals, as well as monitor the overall quality of your air, although it lacks a particle sensor to detect small particles, such as pollen and dust. You can control other devices through the IFTTT channel, depending on the readings you get, although these rules only work when your phone is in range of Bluetooth.

People are becoming more aware that the quality of indoor air is just as important, if not more, than the quality of the outside air. After all, we spend a lot of time there. A toxic domestic environment can therefore affect our health. Although we have reviewed many air quality monitors in the past, the Airthings Wave Plus is the first device to measure radon, a radioactive gas that can cause lung cancer.

For those living in areas with high levels of radon, a monitor of this type should be essential. The neat wireless design makes this product easy to install and offers a well-designed application, but the Bluetooth connection alone slightly reduces its usage.

Airthing Wave Plus – What You Need to Know

  • Detection performance: Excellent if you need a radon detector, but other sensors are more limited and better suited to general comfort.
  • features: An integrated radon alarm is helpful and you can wave your hand in front of the detector to see the current air quality.
  • Control: There is an IFTTT channel for controlling other devices, although this only works if your phone is within range of Bluetooth.

Airthings Wave Plus is easy to install and the application is a useful way of monitoring over time, but the range of sensors is a bit limited.

Screw the backplate to a wall or ceiling, away from the vents or windows, insert the batteries into the Airthings Wave Plus and attach the air quality sensor to the bracket, and voila . The application is not necessary for general use, you can simply move your hand in front of the device to see the status of the air quality: green for good, average yellow and red for poor quality .

Airthings Wave Plus Batteries

Powered by two AA batteries, the air quality sensor activates quickly

Your hand should be a few inches away from the Wave Plus airthings to activate the sensor. Be sure to place the device within easy reach.

As useful as it is to see the air quality at a glance, you will need the smartphone app, which connects to the Wave Plus via Bluetooth. When your phone is in range, it automatically downloads the latest information to display on the screen.

From the main screen, you can see the same preview of your air quality, using the same color scheme, but you also get individual readings for each of the Wave Plus sensors. Radon is probably the most important sensor of the product.

Produced from naturally occurring uranium, radon is a radioactive gas that usually comes from the soil. It is usually the largest source of radiation to which we are all exposed and, at high concentrations, may increase the risk of lung cancer by gas inhalation.

A radon detector is recommended for people living in areas with high levels of radon. You can find out more about radon and use the interactive map at the following address:

For radon, the Airthings Wave Plus starts measuring immediately, but it takes an hour to produce the first radon reading, then a week to get accurate results. The application monitors levels and you can use historical readings to see how radon levels have fluctuated. The results are recorded in becquerel (SI derived radioactivity unit) per cubic meter.

Radon monitoring over time helps you stay safe and is recommended in areas with high concentrations of gas

At levels between 0 and 48 BQ / m3, no action is required. 49-99Bq / m3 indicates that you need to ventilate your house and seal cracks; 100-149BQ / m3 indicates that you must continue to measure and seek professional help for radon reduction if levels remain the same for three months; 150 Bq / m3 and more, you must monitor and seek advice if the levels do not drop after a month.

High levels of radon also trigger the alarm, which can be turned off in the app or turned off for a month by waving the hand in front of the Airthings Wave Plus.

The Airthings Wave Plus also has other sensors. Tap on any reading and you’ll find yourself on a page that displays the historical levels as well as the current status, with a colored ring telling you whether your air is good, medium or bad.

TVOC measures the total amount of volatile organic compounds (VOCs), which are powerful chemicals that can be found in some cleaning products and even in old furniture glue. At high levels, VOCs can cause irritation of the eyes, nose and throat, and even damage to the liver and kidneys. An air purifier can help solve the problem if it is able to capture the gases.

You can see VOC levels and manage them using air purifiers

If these numbers skyrocket, it is helpful to determine what may have caused it, for example by using a particular paint or cleaning product and then changing brands.

Beyond that, the Airthings Wave Plus has sensors more concerned with comfort. The temperature sensor is probably the least helpful because you can usually get away with it when it’s too hot or too cold. The moisture sensor is convenient because it is too wet and you can have mold growth, too dry and you can get dry skin and breathing problems. Opening a window, or operating a humidifier or dehumidifier can help.

The CO2 sensor helps you know when the air is cool. High levels can cause headaches and problems with concentration and can be solved by opening a window. Finally, there is a barometric pressure sensor, with a high pressure related to headaches. Opening a window can equalize the pressure with the outside, but that will not necessarily help if the pressure is high outside.

It’s a shame that there is no particle sensor to warn you of high levels of small particles, which can cause respiratory problems and be a source of allergens, such as pollen. Airthings will add a more generic level of outside particles to the dashboard, but Airthings will still not measure the level of small particles in your home.

There is an IFTTT channel to automate your response and Alexa support – but the Bluetooth connection limits its use

Airthings has a complete IFTTT channel for you to automate your response to levels. For example, if the humidity exceeds a certain level, you can trigger a smart plug to turn on a dehumidifier and turn it off when the humidity drops. Similarly, if you have an automated vent, you can cool a room with a lot of CO2.

You can also use the sensors to generate alerts, such as turning on all of your Philips Hue lights in red if there is a high concentration of radon. As good as it sounds, reads are only accurate when you last loaded data into the cloud, and this only happens when your phone is within range of your Airthings Wave Plus Bluetooth. If you go out, the IFTTT channel will not work.

A hub will soon arrive, which will allow Airthings Wave Plus to communicate with online servers without the need for a smartphone, but it is currently only available for pre-order. Airthings has an Alexa skill, although this only allows you to get a current reading of the radon level. Once again, your phone needs to download the latest information to be accurate.

Should I buy Wave Plus Airthings?

If you live in a high-radon area, Airthings Wave Plus lets you monitor levels and ensure your safety. In this case, it is a great tool and the minor inconvenience of having your phone within range of Bluetooth is not such a problem.

Apart from the radon sensor, the Airthings Wave Plus does less than its competitor Foobot, which can also detect particle levels. In addition, because Footbot is powered and uses Wi-Fi, it can trigger IFTTT rules even when your phone is out of range.
