How Does Indoor Air Quality Monitor Work?

A measurement station is used to assess indoor air quality (IAQ) in real-time. It is equipped with sensors specific to each of the pollutants studied (CO 2, NOx, VOC, PM2.5, etc.), the number of which varies according to models 3 and 6. The technologies used vary according to the pollutants such as infrared spectrometry for the Nox and CO2. The data is analyzed in real-time and communicated directly as appropriate on the screen of the device or via a color code.

They are sent simultaneously to the mobile application of the device which allows analyzing the data.

Although recently introduced to the consumer market, air quality meters have been around for decades. The professional quality of these devices is particularly precise and reliable. Scientific measurements of air quality meet many regulated requirements.

Selection Criteria

To select the most reliable and practical devices to use, we have listed the main players and market participants and then we have researched the different models available. Certain criteria appeared to us more essential than others.

Measurement Capabilities

The device must be versatile and measure with great precision the main pollutants like PM2.5 particles of matter and VOCs, these volatile chemical compounds are known for their negative impact on health like the best known of them, Formaldehyde, which is used in the composition of foams, plastics, and other adhesives.

It is important to also integrate temperature and humidity measurements, two factors that influence the development of biological pollutants such as mites, viruses, and mold spores. Having these 2 simple pieces of information allows you to take the necessary measures such as humidifying or dehumidifying the air and lowering the heating.

Display Screen

This measuring device is primarily designed to transmit information. We set out to find the models that do this as clearly as possible. Although most air quality monitors have a screen to display the measurements, this is not the case for all models sold. It seems fundamental to us to be able to precisely monitor the rate of pollution in the air which is not the case with equipment that communicates the data by a simple color code. It is then important to have a practical and ergonomic interface to read the data easily and to be able to turn off the screen at night so as not to disturb sleep.

Data in Real-Time

The speed of analysis and data transmission makes it possible to differentiate the best models from the worst. Displaying data in real-time or with a short delay allows you to react quickly in the event of an abnormal fluctuation and to make the right decisions such as opening windows or activating an air purifier.

Design and Ergonomics

We have also focused on selecting devices designed for pleasant and practical use. The design of the product is important when it comes to placing it on your bedside table or in the kitchen. We also took into account the quality of the materials used and the finish. The application interface is also essential. You may see it even more than your air monitor screen. Navigation in the menus must be simple and intuitive.

Connected Device

While most measuring devices display data directly, this is not enough to track the concentration of ambient air pollution. The transmission of data on a mobile application has the advantage of allowing, on the one hand, to consult the measurements from anywhere and on the other hand to follow the variations by consulting the daily, weekly, or monthly history displayed in the form of curves and graphs. A connected device also offers measurements from weather stations and outdoor air quality monitoring near you.

Smart Features

This criterion is not essential but provides real comfort. A connected and smart device can interact with voice assistants like Google Home or Alexa and by extension control an air purifier, dehumidifier, or HVAC system (heating, ventilation, air conditioning).

Convenient Installation

The device should be easy to install and connect with its app. Some models require a very simple connection, for others, the operation is more random. Some models also require a long calibration of the sensors before they can be used.

We took into account other important elements starting with the price which is a blocking factor. The customer comments that we encountered during our research brought certain clarifications and pointed out the defects of certain models.
