Carbon Monoxide Detector: The Invisible Saviour for Your Home Safety


blog89-carbon monoxide alarm
Carbon monoxide (CO) is a colourless, odourless, and tasteless gas – which is why it is often referred to as the "invisible killer". It is produced by the incomplete combustion of fossil fuels such as gas, oil, coal, or wood, for example, in heating systems, gas stoves, wood-burning stoves, fireplaces, or even in cars running in enclosed spaces (like garages). Even low concentrations can cause severe health damage – ranging from headaches, nausea, and fatigue to unconsciousness and even death. Especially in apartments, houses, or holiday accommodations where heating systems or cooking appliances are used, a reliable carbon monoxide detector is therefore not a luxury but a necessary safety measure.

Why is a carbon monoxide detector absolutely essential?

Many people underestimate the danger of carbon monoxide because the gas is imperceptible. Often, the first symptoms (such as tiredness or headaches) are mistakenly interpreted as a cold or overwork – until more serious consequences occur. A carbon monoxide detector continuously monitors the air quality in your home and triggers a loud alarm when the safe CO concentration is exceeded. This gives you timely warning to take action: open windows, stop using fuel-burning appliances, evacuate people from the building, and if necessary, call emergency services. Without a detector, the danger remains unnoticed – and this can be fatal in a very short time.

What should you consider when choosing a carbon monoxide detector?

Not all carbon monoxide detectors are of equal quality. To ensure you buy a reliable device, here are the key points to consider:

1. Compliance with standards (e.g., EN 50291)

The most important requirement for a high-quality carbon monoxide detector is compliance with European standards – in particular, EN 50291. This standard regulates the requirements for the accuracy of CO measurement, the alarm response time, the durability of the sensor, and the safety functions of the device. A detector certified to EN 50291 guarantees that it meets strict safety standards and works reliably in emergencies. Avoid cheap devices without standard certification – they may measure inaccurately or trigger the alarm too late.

2. Sensor quality and durability

The sensor is the heart of the carbon monoxide detector. There are different types of sensors, including electrochemical sensors (the most common and reliable) and optical sensors. Electrochemical sensors react quickly to carbon monoxide and provide accurate measurement results. Also, pay attention to the durability of the sensor: most high-quality sensors last between 5 and 7 years – after this period, the detector or sensor should be replaced to ensure functionality.

3. Alarm functions

The alarm of the carbon monoxide detector must be loud and unmistakable – ideally with a volume of at least 85 decibels (dB), so that it can be heard even in other rooms or when music is playing. Some advanced models also have visual alarms (e.g., flashing LED lights) to warn people with hearing impairments. Some devices also offer different alarm levels: a weak alarm for low CO concentrations and a louder, continuous alarm for high concentrations.

4. Ease of installation and operation

Carbon monoxide detectors should be easy to install and operate. Many models can either be mounted on the wall or placed on a table – it is important that the detector is placed near fuel-burning appliances (but not directly above them to avoid false alarms) and near bedrooms (since people are particularly vulnerable to CO damage while sleeping). Operation should be intuitive: simple buttons for on/off, test function, and if applicable, a display for CO concentration (in ppm – Parts per Million).

5. Additional functions

Some carbon monoxide detectors offer useful additional functions, such as a test button (to regularly check the alarm function), a battery warning (to know when to replace the batteries), or a memory function (to store the highest CO concentration measured since the last reset). Newer models also have smart functions: connection to a smartphone app to receive remote alarm notifications or monitor the detector from anywhere.

How to correctly install and maintain a carbon monoxide detector?

Even the best carbon monoxide detector will not work optimally if it is installed incorrectly or neglected. Here are the key tips for installation and maintenance:
  • Placement: Install the detector on every floor of your home, especially near bedrooms and close to fuel-burning appliances (e.g., heating system, gas stove). Make sure it is not placed directly near windows, air vents, or heat sources (e.g., radiators) – this can cause false alarms. The optimal installation height is between 1.5 and 2 meters above the floor (since carbon monoxide is lighter than air and accumulates in higher areas).
  • Maintenance: Test the detector regularly (at least once a month) using the test button to check if the alarm works. Replace the batteries according to the manufacturer's instructions (usually every 6-12 months) – even if the battery warning has not yet been triggered. Clean the detector regularly to remove dust (with a soft brush) to avoid impairing the sensor function. Replace the entire detector after its service life (usually 5-7 years), even if it seems to still work – the sensor loses accuracy over time.
