Is Airthings Capable Of Detecting Carbon Monoxide Gas?

Danger of carbon monoxide poisoning

CO is a colorless, odorless, and tasteless poisonous gas that can be emitted by various household appliances, including gas furnaces, boilers, and stoves. 

This gas is a result of incomplete combustion, and it can accumulate in enclosed spaces, such as homes and garages, leading to potential health hazards.

Being subjected to elevated levels of CO may result in a variety of symptoms, including headaches, dizziness, nausea, weakness, confusion, and even death. 

The symptoms of CO poisoning are often mistaken for other illnesses, making it essential to have a reliable way to detect the presence of CO in your home.

Airthings monitors are an excellent way to detect a range of other pollutants in your home. However, they do not have the capability to specifically detect CO

Therefore, it is crucial to have a dedicated CO detector installed in your home to protect yourself and your loved ones from the potential dangers of CO exposure.

CO detectors are specially designed to detect even low levels of CO gas and sound an alarm when CO levels become dangerous. These devices can be purchased from hardware stores or online retailers and are relatively easy to install. 

Moreover, it is important to read and follow the manufacturer's instructions carefully and to regularly test your CO detector to ensure that it is working correctly.

It is also worth noting that CO detectors have a lifespan and may need to be replaced every 5-7 years, depending on the manufacturer's recommendations. Also, it is essential to keep track of the age of your CO detector and replace it when needed.

What Pollutants Can Airthings Monitors Detect?

Airthings monitors are designed to detect a range of pollutants and contaminants that can affect indoor air quality. Here are some of the main pollutants that Airthings monitors can detect:


The colorless and odorless gas known as radon is created when uranium naturally decays in water, rock, and soil. It can enter buildings through cracks and foundation openings and may accumulate to hazardous concentrations. If individuals are exposed to high levels of radon for extended periods, they may have an increased risk of developing lung cancer.


They are a group of chemicals that are emitted by a variety of household products, such as paints, solvents, cleaning agents, and building materials. Itchy eyes, noses, and throats, headaches, and nausea are just a few of the symptoms that might appear after being exposed to high concentrations of VOCs.


The combustion of fossil fuels and human breathing both result in the release of CO2, an odorless and colorless gas. High levels of carbon dioxide can indicate poor ventilation and can cause headaches, dizziness, and fatigue.


It refers to the amount of moisture in the air. Mold and mildew can grow more readily in environments with high humidity, which can cause respiratory problems, while low humidity can cause dry skin, respiratory irritation, and other health problems.


Temperature can affect indoor air quality by influencing the rate of chemical reactions and the growth of microorganisms. High temperatures can cause discomfort and increase the risk of dehydration, while low temperatures can contribute to the growth of mold and other pollutants.

Air pressure

It refers to the force exerted by air molecules on a surface. Changes in air pressure can affect ventilation and the movement of pollutants in the air.

In addition to these main pollutants, Airthings monitors may also be able to detect other pollutants, such as formaldehyde, nitrogen dioxide, and particulate matter. However, the specific pollutants that an Airthings monitor can detect will depend on the model and features of the device. 

It's important to carefully review the specifications of a monitor before purchasing it to ensure that it will meet your needs and address your specific concerns about indoor air quality.

What Are The Recommended Locations For Installing Airthings?

To get the most accurate and representative readings, it is important to install Airthings devices in appropriate locations. Here are some recommended locations for installing Airthings:

Living Areas

Areas such as living rooms, bedrooms, and family rooms are good locations for Airthings devices as they are typically the areas where people spend the most time.


These areas can be a significant source of indoor pollutants due to cooking activities, and installing an Airthings device in this area can help monitor for CO, VOCs, and humidity.


Basements are a common location for radon buildup, and an Airthings device can help detect elevated radon levels.

Home Offices

If you spend a significant amount of time working in a home office, consider installing an Airthings device to monitor for pollutants that can affect indoor air quality.


The detrimental consequences of indoor air pollution are more likely to affect young children and babies, so installing an Airthings device in a nursery can help ensure that the air they breathe is as clean as possible.

When installing an Airthings device, you should follow the manufacturer's instructions for placement to avoid areas that are too close to doors, windows, or air vents, as these can affect the accuracy of the readings. Regular calibration of the device is also recommended to ensure accurate and reliable data.
