If you are looking for cooling on hot days, the Qlima LK 2100 is what you need. No hassle with drain hoses or connections. Simply fill the large water reservoir with water and the device provides immediate cooling in the form of ventilation and water evaporation.
The honeycomb cooling mats of the Qlima LK 2100 are very durable and require little maintenance. In addition, they are extremely efficient.
The temperature in the room will actually decrease, which is not the case when using a fan. However, the cooling effect cannot be compared to that of a mobile air conditioner. On the other hand, the advantages of an air cooler are that you do not need to route a drain hose to an external vent and that the purchase price is significantly lower.
