Measuring Particulate Matter: Why Air Quality Matters and How It's Done
Particulate matter is an invisible pollutant that floats in the air and poses a considerable burden on health and the environment. Especially indoors, particulate matter can impair air quality unnoticed. But how can you measure particulate matter, and what options are there to reduce exposure?

What is particulate matter, and why is it problematic?
Particulate matter consists of tiny particles in the air with a diameter of less than 10 micrometers (PM10) or even just 2.5 micrometers (PM2.5). These particles can penetrate deep into the airways and cause health problems such as:
- respiratory diseases,
- cardiovascular problems and
- allergic reactions
In addition to industrial emissions and traffic, wood-burning stoves and other heating systems also contribute to particulate matter exposure, especially in enclosed spaces.
How can you measure particulate matter?
To effectively measure particulate matter, specialized particulate matter monitors or devices with particulate matter sensors are used. These devices analyze the air for particles such as PM10 and PM2.5 and provide information about air quality in your home.
Methods of particulate matter measurement
- Laser-based sensors: Most modern particulate matter monitors use lasers to detect the number of particles in the air. This method is fast and precise.
- Gravimetric methods: These measure the weight of the particles and are very accurate, though better suited to professional applications.
- Portable particulate matter monitors: These devices are compact and ideal for home use. They can often also measure additional parameters such as temperature, humidity and TVOCs (volatile organic compounds).
Particulate matter monitors for the home: how to find the right model
Choosing a particulate matter monitor for home use depends on your individual needs. Here are a few aspects to consider:
1. Measurement range and accuracy
A good particulate matter monitor should precisely capture the concentration of PM2.5 and PM10. These values are crucial for correctly assessing air quality.
2. Additional measurement functions
Some devices measure not only particulate matter, but also other environmental factors such as:
These functions are useful for getting a comprehensive picture of indoor air.
3. Ease of use
A simple operating concept and an easy-to-read display make handling easier. Portable devices with app connectivity offer additional convenience features such as data storage and analysis.
4. Applications for wood-burning stoves
For households with wood-burning stoves in particular, there are devices that measure emissions directly at the stove. These help optimize the stove's efficiency and control particulate matter exposure.
Is the air-Q suitable as a particulate matter monitor?
With a particulate matter monitor like the air-Q, you can specifically analyze the composition of your indoor air. It uses an infrared laser that reliably detects and distinguishes between particles of different sizes. The high-quality sensor ensures especially high measurement accuracy.
The air-Q particulate matter sensor detects the smallest particles using optical scattering. Inside the sensor, an infrared LED and a detector are isolated from each other by a partition. As soon as a particulate matter particle passes through the LED's light, the detector registers a brief flash. Larger particles produce brighter flashes, while smaller particles produce weaker signals. The air-Q counts these flashes, providing extremely precise readings on particulate matter exposure indoors.

Tips for reducing particulate matter indoors
In addition to measuring, you can also actively reduce particulate matter exposure in your home:
- Ventilate: Regular brief airing helps improve air quality.
- Efficient heating methods: Use low-emission heating systems and make sure your wood-burning stove is well maintained.
- Air purifiers: Use air purifiers with HEPA filters to remove particulate matter from the air.
Conclusion
Particulate matter monitors for the home offer an effective way to monitor air quality and minimize health risks from particulate matter. Households with wood-burning stoves in particular should pay attention to keeping particulate matter exposure low. With the right devices and preventive measures, you can make your living environment healthier and benefit in the long run.
