I like Dyson products in general. However with this product I don't know whether intentionally or no but Dyson confuses the customers. Digitec also gives in the description like "you can choose a strong cleaning with or without cooling function". This suggests to the customers that the device works like an air conditioner by cooling the temperature. That's why I have purchased the product. But it's NOT TRUE!!! There is NO COOLING FUNCTION!!! It's just a purifier of the air and a ventilator. By the way looking at the brochures of other similar products of Dyson I think Dyson uses the world "Cool" in the name regularly for devices without cooling function.
