About the customer
Danish kindergarten
A new filter and a four-month-old filter side by side. That is how clearly you can see the difference between clean and polluted indoor air.
4 months on the filter
The challenge
In a kindergarten, children and adults spend many hours every day in rooms where dust, pollen and particles circulate constantly. Even if the problem is not always visible, it affects the indoor climate and can take a toll on both wellbeing and concentration.
Dust and particles circulate in the rooms all day
No visible way to assess the indoor climate
Children and staff spend 7-8 hours in the rooms
The analysis
By installing a Pure Air Slim 487 and letting it run for four months, we got a concrete picture of what is actually in the air. When the filter was replaced, the difference between the new and the used filter was clear to see — and to measure.

The filter documented the actual air quality
The difference between new and used filter was clear
The solution
We set up a mobile air purifier that removes harmful particles, gases and odors with an advanced six-stage filtration system. The solution required no renovation or fixed installation, and it could be moved as needed.

Mobile solution with no renovation
Removes particles, pollen, odors and gases
The result
The filter showed how much dust and how many particles had been captured in just four months. For the kindergarten, this meant a documented improvement in air quality — and a reminder that clean air is not a luxury but a prerequisite for a good work environment.

“The difference between the two filters makes it very concrete what the air purifier has captured from the air over four months of operation.”
