- During June and July, we have an increase of almost 200 percent compared to the same period last year, says Camilla Waldmark, PR and communications manager at Elon.

It is clear that sales follow the heat.

According to Camilla Waldmark, Elon notices a trend where more people choose portable air conditioning over the traditional fan.

- It can certainly have to do with more people working from home, she says.

Increased by 50 percent

The pressure is also great on Elgiganten.

During the month of July, sales of fans increased by almost 50 percent compared with the corresponding period last year.

- After last summer's record sales of ac and fans, we did not think that the interest could be much greater.

It is clear that sales of these products will increase as soon as it gets warmer, says sales manager Sara Larsson.

"Very high demand"

Kristina Wärmare, head of PR and communications at Netonnet, says that they notice the same tendencies.

- As always when there is a heat wave, we see a very large demand for products such as portable air conditioning and fans - this year is no exception, she says.
