Question about Dyson Pure Cool Link

There is no alternative to air conditioning. It's just a fan. The air is not cooled. The temperature does not drop in the room. It just swirls the air and does not really provide cooling. I have the Dyson AM09 Hot Cool. It is similar to the Dyson Pure Cool Link Tower only without air filter. In the summer I place it early in the morning, when the temperatures are below 20 degrees, directly in front of the open window, the room is cooled quickly. If you want to have cool you have to buy an air conditioning.
