Air Quality legislation in France and in other countries

Air Quality is a major health concern around the world. The World Health Organisation has issued guidelines about health effects and exposition threshold for the numerous pollutants that ends up in the atmosphere from natural phenomena and human activities. Most big cities periodically or punctually exceed these guidelines for certain pollutants. Indoor Air Quality, while less well-know and mediatized, is at least as deadly if not more.

In France, the French Labour Law and the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) issued a set of threshold values for work environment exposure to most pollutants (VLEP).

Since 2018, the Grenelle 2 Decree has come into force for all ERP (Establishment Receiving the Public), in 3 major steps to raise public awareness of indoor air quality.

In Belgium, the Code du Bien-Être du travail (Workplace well-being code) also provides guidelines and threshold for pollutant concentration in workplaces, including for specific work or rooms.

In the UK, the NICE (National Institute for Health and Care Excellence) also recently updated its guidelines on Indoor Air quality.

In Dubaï, threshold values are also given, by the Dubai Municipality.



Indoor Air Quality presents major stakes for health and well-being

IAQ Indoor Air Quality

Corporate Societal Responsibility (CSR) compliance 

  • Health, comfort and well-being of the occupants
    Life Quality and Air Quality are intricately linked. Aside from simple discomfort, headaches, dry throat, stinging and nasal congestion are direct and immediate effects of a bad Air Quality.
  • Risks prevention
    Many chronic affections and diseases (COPD, asthma, allergic rhinitis, PND, etc.) can be directly associated with chronic bad air quality.

Financial stakes of IAQ

  • Performance and productivity enhancements
    Somnolence, rhinitis, throat aches… A bad Air Quality will impact performance through loss of attention, discomfort or absenteeism, therefore limiting productivity.
  • Three ways to solve a sanitary problem
    There are three common ways to solve sanitary problems: through Reactive, Preventive or Predictive methods.
  1. The Reactive approach comes with diagnosis, and benefits from thorough knowledge of the problem to design a tailor-made solution. It usually comes at a very high sanitary and monetary cost.
  2. The Preventive approach will try to avoid the problem altogether by removing potential source ahead of time through scheduled maintenance. The sanitary cost is lower, but the monetary cost can be higher.
  3. The Predictive way optimise the solution by taking the best of both preceding methods.It continuously diagnose to plan maintenance when needed. Industry 4.0 is notably based on this principle. Predictive cleaning of Ventilation Duct Networks for example is a source of energetic and monetary optimization.

Air Quality and Health

  • A chronic and systemic issue

According to WHO, 91% of the world’s population lives in or goes to places with pollutant concentrations exceeding WHO guidelines. Indoor Air Pollution is as important but a lot less mediatized than smog or pollution veils in big cities.

  • A compounding factor

In recent years, WHO categorize bad Air Quality as a major compounding factor for numerous diseases (stroke, heart diseases, respiratory afflictions, etc.). Each year, close to 7 million deaths are directly associated with bad Air Quality.

  • Susceptible people are at higher risks

Close to half infant deaths by pneumonia are linked to bad air quality (source WHO), most notably from cooking smoke and soot. People with pulmonary deficiencies or diseases and the elderly are also particularly susceptible to complications from a bad Air Quality.



At Zaack, we want to take care of  our environmental and societal impact
We decided to design, manufacture, assemble and recycle everything we produce in France when possible, or in our close European neighbours otherwise. For this objective, we developed many partnerships with SMES in Europe (France, UK, Austria). They, together with our team, are a guarantee of quality and technical excellency, as well as enhanced reactivity and support.

Zaack Dust®

Zaack Pilot of your indoor air quality

Zaack smart solutions ensure real-time and uniterrupted control of your Indoor Air Quality. Connected to the cloud via Ethernet/Wifi (4G option) or LoRa, your data are collected and sent to our servers via a secure connection. A private property of our clients, the data is stored in a secure data centre and can be accessed in real-time via our web and mobile apps.

With the help of deep learning, we get more familiar with the specificity of your buildings with time which allows for more specialized counselling. In conjunction with exterior air quality Open Data, our smart data analysis empowers our clients with more tool to improve and control their IAQ:
Predictive maintenance, fresh air ventilation, air filter replacements…


Indoor Air Quality Monitoring

Zaack IAQ® measures in real-time the most common indoor pollutants. Each pollutant has its own dedicated sensor to ensure specific and exhaustive air quality data. The 11 measured parameters are:

  • Comfort parameters: temperature, relative humidity, atmospheric pressure
  • Gaseous pollutants: CO2 (Carbon Dioxide), NO2 (Nitrogen Dioxide), O3 (Ozone), CO (Carbon Monoxyde), TVOCs (Total Organic Volatile Compounds)
  • Particulate matter: PM1 / PM2.5 / PM10
  • The following pollutants can be measured on demand: H2S (Hydrogen Sulphide), SO2 (Sulphur Dioxide), CH4 (%LEL Methane and Hydrocarbon)

Reliable measurements are ensured by comparison to reference analysers prior to every deployment of our devices.

A validation certificate is also established (currently only on demand).

Zaack IAQ® is a connected monitoring station: every thirty seconds, data logs are sent to the cloud through a secure connection.

Data are available for visualisation through our mobile and web apps. 

We manage the entire platform


Identify pollution patterns specific to each building.

Zaack DUST® :

An innovative product inspired by a Standard…

This standard is based on national legislations and European guidelines. It gives directives about control methods and proper maintenance for air ventilation networks.

Zaack DUST® :
Pilote your HVAC systems



Zaack DUST®  devices can be installed on all types of existing air ventilation ducts in HVAC systems. It is highly recommended to have the network cleaned prior to installation of Zaack DUST®.

Prior to initial operation, our operators must sample the duct to get an estimate of the intial dust deposit. This ensures proper calibration of the device and therefore more reliable data. This can also assess the quality of the previously done cleaning of the duct.

Thanks to the LoRaWAN Gateway, the mean data measured over a week is sent once a week to the cloud via a secure connection. Real-time visualisation of measurements and data export can be done through our Zaack DUST® app.

Our app is set to send alarms based on NF EN 15 780 Standard. A weekly report is sent to the user via e-mail when dust deposition measurements exceed 80 % of threshold value, with additional warning when above threshold.

Zaack DUST® :

A better Control of your Installations

Using Zaack DUST® provides customers with a powerful tool to make predictive maintenance on ventilation ducts:

  • Real-time knowledge about your ventilation network state enables better planning for maintenance, and therefore lowers costs (duct and diffuser cleaning, filter replacement, fan maintenance…)
  • Ensure optimum comfort and diminish potential health-related problems.
  • Energy savings through reduction of pressure drop in the ventilation systems.
  • Fast response through warnings in cases when intervention in needed (NF EN 15780)
