Residential Indoor Air Quality (IAQ) Testing

We bring your air quality into focus!

Do you feel tired or drained? Do you often have a sore throat or a constant tickling in your throat? Do you have dry, burning or watery eyes? Do you have a dry cough and need to clear your throat constantly?

In that case, the air quality in your home may be poor!

People nowadays spend more than 90% of their time indoors. Since the air in the house is usually recycled and the supply of fresh air is usually insufficient, pollutants can accumulate in the air and endanger health.

Now is the time for an independent investigation!

We have compiled a measurement program for air quality measurements, especially for private individuals: The Residential Indoor Air Quality Testing.

The advantage of this special research:

By measuring the concentrations of dust, VOC, CO2, temperature and relative humidity, you will receive an overview of the air quality in your building within 1 to 2 hours!

If the measured values are below the legal limit and guideline values, you can enjoy the harmless air quality in your home without any worries!

If the limit values are exceeded, we can use this data and the inspection of the rooms by our measurement specialist to identify possible sources and causes of air pollution and suggest improvements.

How do we measure?

Various indoor air parameters are measured with a selection of professional measuring devices. The measurements take one to one and a half hours, depending on the number of rooms to be tested. We usually assume one to four rooms, plus a measurement in the outside air on a balcony or at an open window. We adhere to the current ISO standards and follow the rules of the building biology measurement criteria.

For a complete room air measurement for private individuals, we measure the following parameters:

  • temperature
  • relative humidity

During the measurement, you will immediately be informed verbally by our expert about the measured values and possible causes.

After the measurement, you will receive a clear measurement report within a week with the measurement results and advice on how to reduce elevated concentrations.

Do other substances need to be measured, such as formaldehyde (HCHO), ozone (O3), nitrogen dioxide (NO2), carbon monoxide (CO) or radon (Rn)?

No problem!

We can also examine these gases for you. These measurements are charged extra. Just indicate in your request which parameters you want to have measured in addition to the standard examination, and we will send you a suitable quotation.

Long-term measurements (monitoring)

Would you prefer measurements over a longer period of time in order to establish changes over time in the concentrations of various gases and substances? We will be happy to carry out this study for you!

We have IAQ data loggers with which we can monitor particulate matter (fine dust), CO2, temperature and relative humidity, tVOC or radon.

We recommend that you take these measurements over a longer period of time, at least 10 days, in order to measure different or all living situations in your home.

After the measurements, you will receive a measurement report within a week with graphs showing the concentrations during the measurement period.

We ask our customers to keep a logbook during this survey in which they note what happens in the room, e.g. when the windows are opened, how many people are in the room, whether people smoke, whether candles are lit or perhaps a fireplace. This information can be processed in the graphs. You will then know exactly when and why the concentrations of the measured air pollutants have changed.

We will be happy to send you a suitable offer free of charge.

Comparative measurements of outdoor and indoor air

Do you live on a busy road and do you want to know what influence the fine dust pollution from road traffic has on the fine dust concentrations in your home? Do you suffer from a lot of dust in your flat, and do you want to know for sure that the cause lies outside your flat?

By placing a fine dust monitor on the balcony, in the garden or on the windowsill and another monitor in the room, we can compare the concentrations. By taking measurements over several days, we can graphically show the effect that the outdoor air has on your indoor air. Then we can also determine when it is best and safest to air the room.
