Help for optimizing the indoor climate
When should you get an air purifier?
Imagine opening the window to get some fresh air – but instead of purified air, pollen, dust and polluting particles flow in. For many Danes, this is the reality, especially in urban areas, near busy roads and during periods of high pollen counts. The air quality in Denmark is generally good compared to many other countries, but that does not mean that we are immune to problems with the indoor climate. On the contrary, recent studies show that we spend up to 90% of our time indoors – and precisely here the air can often be more polluted than outside.
An air purifier can be an effective solution for improving indoor air quality, but when does it really make sense to invest in one? In this article, we delve into what an air purifier is, who benefits from it, and how to choose the right solution – with a particular focus on Danish homes, institutions, and workplaces.
What is an air purifier – and why is it important?
An air purifier is a device that filters the air in a room and removes particles such as dust, pollen, mold, smoke and other harmful substances. It may sound simple, but the effect can be significant – especially for people with allergies, asthma or other respiratory disorders. According to Power and Elgiganten , modern air purifiers can remove up to 99.97% of particles as small as 0.3 microns if they are equipped with HEPA filters.
At ÅBN, we work to make the indoor climate visible and understandable. We know that it is not only about temperature and CO₂ – but also about invisible particles that affect our health and well-being. Therefore, air purification is a natural complement to our solutions, which help schools, offices and institutions create a healthier indoor climate.
When does it make sense to use an air purifier?
1. When allergies take over
For many Danes, spring and summer mean runny noses, itchy eyes and fatigue. Pollen allergies affect around 1 in 5 Danes, and symptoms are often worse indoors, where pollen collects in textiles and dust. An air purifier with a HEPA filter can effectively reduce the amount of pollen in the air and thus significantly reduce symptoms. According to Coway and Philips , several models are approved by Asthma Allergy Nordic – an important indicator of effectiveness.
2. When children or vulnerable people are in the room
In schools, daycare centers and homes with small children, it is especially important to ensure a healthy indoor climate. Children's airways are more sensitive, and they often stay closer to the floor, where many particles accumulate. An air purifier can help create a safer environment – especially when combined with data and visualization of air quality, which we offer in the Skye solution . This way, you can not only clean the air – but also understand when and why it is necessary.
3. When you live close to traffic or industry
Ozone, NO₂ and ultrafine particles from traffic and industry can enter homes – especially in urban areas. These particles are invisible, but can have a major impact on health over time. An effective air purifier can reduce exposure and create a healthier indoor climate, especially in bedrooms and living rooms, where we spend a lot of time.
4. When you experience bad odors or chemicals in the air
Have you ever painted a room and noticed the smell lingering for days? Or have you had guests who smoke and the smell lingers? Air purifiers with activated carbon filters can absorb odors and chemical compounds that are otherwise not captured by regular vacuum cleaners or ventilation. This is a particular advantage in office environments where many people share the same air, or in homes with pets.
5. When you want less dust and less cleaning
It is not only allergy sufferers who benefit from an air purifier. Less dust in the air also means fewer dust particles on furniture, electronics and floors. This can make cleaning easier and provide a more pleasant experience in the room. Many facility managers in both public and private buildings have noticed this – not least because it can contribute to more efficient operations and better employee well-being.
How to choose the right air purifier?
Start by understanding your indoor climate
The first step is to understand what you need to clean. Is it pollen, dust, smoke, chemicals or just general particle reduction? At ÅBN, we recommend combining cleaning with measurement. With our intuitive sensors and dashboards, it becomes possible to see when the air is bad – and act on it in time. You can read more about our approach to behavior change and documentation here .
Choose a model with a HEPA filter
HEPA filters are among the most effective at capturing small particles – down to 0.3 microns. This makes them ideal for allergy sufferers and people with asthma. According to PriceRunner and other experts, you should prioritize this filter if you want maximum efficiency.
Consider room size and location
An air purifier should match the size of the room it is intended to cover. Large rooms require more powerful models, while small rooms can make do with more compact solutions. It is also important to place it correctly – preferably centrally in the room and free from obstacles.
Look at energy consumption and noise levels
Modern air purifiers are often energy-efficient and quiet, making them suitable for use in bedrooms and offices. Many models have night functions and automatic sensors that adapt to air quality in real time.
Smart control and monitoring
More air purifiers can now be connected to apps and controlled via smartphone. This allows you to monitor air quality and adjust settings – no matter where you are. At ÅBN, we work to make this type of data accessible and understandable, so you can make informed decisions in your everyday life.
The benefits of air purifiers – in brief
- Reduces allergens such as pollen, dust and mold
- Improves indoor climate and air quality
- Removes odors and chemicals
- Reduces the need for cleaning
- Creates security for children, the elderly and the vulnerable
- Supports sustainable operations and health in the workplace
