When civil engineer Anders Holmgren chose to leave the rat race in Stockholm and move with his family to Smedjebacken, they found an old wooden house with great potential but in need of some love. According to Anders, there are many advantages to an old house, such as building materials being better than in newly built houses, which means they do not emit harmful substances.

The house was built in 1942 with two floors and a basement, and today has water-borne district heating and a wood-burning stove. Although the house had been partly renovated, including additional insulation and new modern windows, nothing had been done about the ventilation. As an inspector, Anders could inspect the house himself and concluded that the insulation and new windows had largely stopped the ventilation, leading to a poor indoor climate.

On the upper floor, the attic spaces had been converted into sleeping alcoves, and the air did not reach there. Measurements showed that the carbon dioxide level was too high. Through a friend, Anders got a tip about Airmove, who, during a home visit, recommended two Airmove 1.1 units to create continuous air circulation between the rooms on the upper floor.

Over the coming year, the old wooden house in Smedjebacken will undergo further renovations. However, for Anders, it was important to address the ventilation immediately after the move, both for his family's sake and for the house itself. The installation of the Airmove units went smoothly, and he was satisfied with the result. As a civil engineer, he did, however, have one wish: that the products would also have a built-in carbon dioxide meter to adjust the air intake, which might be the next step in Airmove's development.
