‘A guarantee for healthy indoor air quality’




Clean Air Optima International B.V. was founded in 2002 by Jeroen Kortenschijl and his twin brother Frank Kortenschijl.



We deal with innovative solutions for a fresh and healthy indoor environment to promote your well-being and health!

Studies have shown that people in Europe spend 90% of their time indoors. Recent research by leading environmental protection organisations demonstrates that our indoor air in home and work situations is generally much more polluted by biological and chemical contaminants than outdoor air.

Despite progress, it seems from the annual assessments of air quality in Europe by the EEA (European Environment Agency) that air pollution still continues to pose a threat to human health and the environment. The air pollution levels in many European cities still exceed both the EU's legal limits and World Health Organization (WHO) guidelines on the protection of human health. With tragic consequences: according to EEA estimates, around 400,000 Europeans die prematurely every year because of poor air quality. (Source: EEA - European Environment Agency)

It is estimated that concentrations of particulate matter, nitrogen dioxide and ozone in the air lead to 12,000 premature deaths every year in the Netherlands. (Source: Health Council | No. 2018/01)

According to studies and alarming reports by expert institutions such as the WHO, EPA (U.S. Environmental Protection Agency), the European Environment Agency (EEA) and the Dutch Health Council, the indoor air in our living, working, and mobility areas is often 2 to 5 and even up to 100 times more polluted than the air outside due to biological and chemical loads!

A healthy indoor climate, which is also perceived as pleasant, natural and fresh and conveys a feeling of comfort, is determined by an optimal interaction between humidity, temperature, air movement and air quality (clean breathing air, oxygen content and ion concentration in the air).

Humidity is often the critical factor for an ideal indoor climate. Excessive relative humidity in homes, apartments or buildings can give people health problems. Excessively dry air can have adverse effects on health.




The Clean Air Optima® trademark
Our protected trademark stands for the most important aim of Clean Air Optima International B.V.: to make optimum air quality possible in all interior spaces where people spend time because every individual has a right to clean air and an indoor climate that is good for his or her health.

Being and staying healthy calls for a healthy quality of indoor air!
For more than 20 years now, Clean Air Optima International B.V. has been following its vision of enabling people to be and stay healthy by improving indoor air quality with Clear Air Optima® air treatment systems, suitable for spaces of up to 120 m²/300 m³. Our motto is therefore ‘A guarantee for healthy indoor air quality’ for all indoor spaces in which people live, work and play.

Excellent range of mobile air treatment systems
Our range of effective, stand-alone Clean Air Optima® air treatment systems includes air purifiers, humidifiers, air washers, dehumidifiers, hybrid models for simultaneously humidifying & purifying air or dehumidifying & purifying air, fans, electric-ceramic fan heaters and models suitable for aromatherapy.

The effect
The innovative and energy-efficient Clean Air Optima® air treatment systems with their modern design transform poor, unhealthy, dry or excessively humid indoor air into clean air for breathing. Viruses, bacteria, fungi, pollen, particulate matter, harmful substances and unpleasant odours are filtered out of the air and the relative humidity of the air and temperature in indoor spaces are adjusted to and maintained at the right level.

Design and smart technology
It goes without saying that the attractive and optimised design of our equipment, which harmonises with any interior, combines the greatest effectiveness with the maximum of comfort. For example, smart equipment with intelligent sensor technology and WIFI APP CONTROL is among the options in Clean Air Optima®’s professional and extensive range of mobile, stand-alone devices to improve the indoor climate.

Clean Air Optima story





From idea to enterprise

With ample experience gained in the electrical industry and technical trading company, twin brothers Jeroen and Frank Kortenschijl decided to become entrepreneurs based on their vision of wanting to help people live healthier and longer lives by ensuring clean and well-conditioned air in spaces where people live, work and recreate.

“Breath is the essence of life”

The interior has become the typical abode for modern man. It’s somewhere we often spend as much as 90 per cent of our time. A human being breathes in and out an average of 18,000 to 24,000 times a day. This means that an average-sized adult who does not perform heavy physical labour inhales and exhales an average of 11,000 litres of air per day. This greatly exceeds the amount of food and drinking water consumed each day. While food and water can be carefully selected, this is generally not possible with the air we breathe.

According to research and alarming reports by qualified institutions such as the WHO, EPA and the European Environment Agency (EEA), the indoor air in our living, working and mobility areas is often 2 to 5 and even up to 100 times more polluted than the air outside due to biological and chemical loads!

Anticipating this, the two entrepreneurs decided to establish the Clean Air Optima® brand and the company Clean Air Optima International B.V. and to launch a range of effective new mobile air purifiers with multi-filter technology to be sold online in the Benelux, allowing prospective customers to protect themselves from the risks of poor, unhealthy indoor air in their living spaces at an acceptable purchase price.
