Indoor Air Quality for the health and well-being of people, and improved energy efficiency of buildings

We are celebrating 20 years

What we have learned during this time has allowed us to position ourselves as pioneers and market leaders, both in technology and in business: raising awareness and educating people on the importance of breathing quality indoor air.

Why is indoor air quality so important?

We are inspired by people’s well-being

We promote innovative projects and solutions for companies in various sectors, including hospitals, offices, schools or public buildings to improve indoor air quality, which has positive effects on health, sustainability, energy efficiency and productivity.



The value of a healthy building lies in the fact that it improves indoor air quality, impacts the entire workforce and projects company values.


Improving indoor air quality and placing value on health and sustainability are key elements in the design and development of real estate assets.


The protection of indoor air quality in a hospital environment must be comprehensive and includes patients, healthcare staff and visitors.
