Are employees struggling with pollen problems at work?
Pollen allergy is one of the most common health problems in Norway, and for many employees it becomes a real challenge in their everyday work. Itchy eyes, runny nose, fatigue and difficulty concentrating don’t just reduce quality of life – they also affect productivity.
While good ventilation filters have long been the standard for keeping the air clean, research and experience show that humidity plays an equally important role in how the indoor climate is perceived. An excessively dry indoor climate can significantly exacerbate pollen complaints. Fortunately, there are smart solutions that address this directly in the ventilation system.
Pollen problems worsen indoors
In spring and early summer, the outdoor air is filled with pollen from trees, grass and herbs. Modern office and public buildings are tightly insulated and have efficient ventilation systems that filter out a large proportion of the particles. Yet many employees report that their symptoms persist or even worsen indoors. The cause often lies in the relative humidity of the air.
When the air is too dry – typically below 30-40% relative humidity, which is common in heated buildings in winter and early spring – the pollen particles float around the room more easily. They stay in the air longer and are more easily inhaled. At the same time, the mucous membranes in the nose, throat and eyes dry out, weakening the body’s natural barrier to irritants.
The result is increased irritation, more frequent sneezing and general discomfort. Several studies show that optimal humidity (40-60%) can significantly reduce the spread of aerosols and allergens. Humidified air causes pollen particles to bind to water vapor, become heavier and fall faster to the floor where they are easier to remove through cleaning or ventilation.
Orbit Wing – an innovative solution from Merlin®
One of the most effective technologies on the market today is Orbit Wing® from Merlin Technologies. This is a patented system for duct-based humidification that integrates directly into existing ventilation systems.
Orbit Wing adds microscopic water droplets to the air before it is distributed into the building. The system is energy efficient, hygienic and requires minimal maintenance compared to older humidification systems. It is also available in a hybrid version that both humidifies in winter and contributes to adiabatic cooling in summer.

This is how it works in practice:
- Sensors continuously monitor relative humidity in the ventilation ducts.
- Orbit Wing adds exactly the amount of moisture needed to maintain a stable level.
- The water is distributed as extremely fine droplets that evaporate quickly without leaving moisture on surfaces – thus avoiding the risk of mold or bacterial growth.
A better working day for employees
When humidity is kept at an optimal level, several positive things happen at the same time:
This is particularly valuable in office buildings, schools, hospitals and other buildings where people spend long periods of time. In many industries where performance and production depend on mental acuity, a good indoor climate can make a noticeable difference.
A sustainable choice
Merlin Technologies has extensive experience in humidification technology for industrial, office and specialty buildings. The Orbit Wing system is known for its low energy consumption and high reliability, making it a forward-looking choice at a time when both energy efficiency and indoor climate are high on the agenda. Many employers also find that the investment pays off through reduced sick leave, increased well-being and more alert employees.
Pollen problems at work are not something you just have to accept and live with. By combining effective ventilation filters with active humidity control through solutions such as Orbit Wing, you can create an indoor climate that feels cleaner, fresher and more comfortable – all year round.
Employers who invest in a good indoor climate show that they take their employees’ health seriously. At a time when competition for qualified labor is fierce, an optimal indoor climate can be an important competitive advantage.
