Air in Focus for 34 Years
Did you know that a person does not age at the same rate throughout life? Scientific research shows that the ageing process does not occur linearly, but rather in waves. A study published in Nature Medicine indicates that more pronounced biological changes occur around the ages of 34, 60, and 78, when shifts in blood protein profiles take place. When air is in focus, one simple question arises: how much air does a person breathe during that time?
Believe it or not, an average person inhales more than 150 million litres of air over 34 years. This means that the quality of air a person is exposed to throughout life represents one of the most important factors influencing health.
Does a Company “Age” Linearly?
No life is linear – nor is the life of a company.
The journey of Marquis Intelligence over 34 years has not been linear. As with any long-term development, there have been periods of growth, as well as challenges that required adaptation, learning, and difficult decisions.
These moments have shaped the company’s approach – based on knowledge, responsibility, and a willingness to go one step further when necessary. The focus on air has remained constant.
Air at the Core of the Company’s Work
For 34 years, Marquis Intelligence has focused on something invisible, yet directly affecting health, quality, and lifespan – air. Although this field was not always in the public spotlight, it has always involved serious challenges. Addressing them – then and now – requires technical understanding, precision, and responsibility. This approach has remained unchanged.
Today, as air quality increasingly comes into focus among both professionals and the wider public, it becomes clear that its importance has long been underestimated. Indoor air quality is particularly critical, as this is where people spend most of their time.
How Many People Actually Breathe Good Outdoor Air?
Unfortunately, far fewer than we might expect. According to data from the United Nations and the World Health Organization, 99% of the global population breathes outdoor air that exceeds safe pollution limits. This has serious consequences for health, the economy, social equality, and the environment.
Indoor air often poses an even greater risk to health, quality of life, and longevity.
Why? Because people spend around 90% of their time indoors, where, according to the US Environmental Protection Agency (EPA), air can be 2 to 5 times more polluted than outdoor air.
What Is Indoor Air Quality?
Indoor air quality refers to the composition of the air we breathe in homes, apartments, and offices. It includes: oxygen and nitrogen levels, relative humidity, concentration of pollutants and ionic composition. Key pollutants include: PM10, PM2.5, and PM1 particles, nitrogen and sulphur oxides, carbon dioxide and carbon monoxide, ozone and microorganisms and allergens.
Indoor air quality directly affects health, comfort, cognitive performance, and productivity.
Its impact is particularly pronounced for vulnerable groups such as children, pregnant women, the elderly, and people with health conditions.
How to Recognise Poor Indoor Air Quality?
Poor indoor air quality may manifest as: stuffiness, unpleasant odours and excessively high or low humidity. It may also be identified through symptoms such as: unexpected fatigue and reduced concentration, headaches, frequent yawning, eye irritation, dry throat and brittle nails. These signs often indicate that the air quality in the space is inadequate.
Raising Awareness of Air Quality
For more than three decades, Marquis Intelligence has consistently highlighted the importance of the air we breathe.
The company’s Blog features numerous scientifically grounded articles addressing the impact of air quality on health, comfort, and human performance across different environments. Through this content, air is not treated as an abstract concept, but as a measurable and manageable factor that directly affects everyday life.

Understanding Does Not Mean Implementation
Awareness of air quality has increased significantly in recent years. However, the gap between understanding the problem and implementing technical solutions remains large – especially when it comes to indoor air pollution.
And where do we spend most of our time indoors? At home. Therefore, ensuring good air quality at home is one of the most important preventive health measures for both individuals and families.
Who Is Responsible for Air Quality in Your Home?
You are. Why? Because achieving healthy indoor air is possible – and the decision to do so is yours.
How can you ensure good air quality at home? Through proper technical solutions combined with energy efficiency.
For this reason, Marquis Intelligence has focused its activities in the past year on residential ventilation systems with additional air treatment in accordance with DIN 1946.6.
Air remains the focus, but attention is increasingly shifting towards the space that affects people the most – the home. According to Harvard research, we spend approximately 65% of our lives at home.
Continuity and Development Over 34 Years
Thirty-four years of work in air quality represent not just a period of time, but continuity in understanding and approach.
In an industry that evolves through technologies, standards, and market demands, consistency in methodology and quality remains a core value. This is an approach based not on trends, but on principles that deliver verifiable results.
Digital Development and Knowledge Structuring
In recent years, Marquis Intelligence has placed strong emphasis on digitalisation and the structuring of professional knowledge.
As a result, the company’s digital presence continues to grow, to make complex topics in air quality accessible, understandable, and applicable.
Modern business environments demand clearer structuring and accessibility of knowledge. For this reason, the Marquis Intelligence website is entering a new phase of digital maturity and becoming a reference point for ventilation and air quality information.
FAQ on the Occasion of the 34th Anniversary
To mark its 34th anniversary, Marquis Intelligence expanded its website with new content in the FAQ section on ventilation and air quality.
These pages systematise knowledge through answers to frequently asked questions, organised into multiple thematic sections and subsections.
In this way, the company’s long-term experience becomes accessible and useful to both professionals and the wider public.
If today we know more about air than ever before, the real question is no longer whether it is important, but why it is still neglected.
What Comes Next?
Through its approach, Marquis Intelligence confirms its direction for the future – not only as a contractor, designer, and service provider, but also as a reliable source of structured knowledge in air quality.
Air will increasingly become the focus of broader public interest.
But for Marquis Intelligence, air has been in focus for 34 years.
