Air Cooler (Luftkühler) Stock in Germany

Buying guide

An air cooler draws air through a wet pad or over an ice tank, cooling it by evaporation. It uses a fraction of an air conditioner's power and needs no exhaust hose, but it works best in dry heat and adds humidity — so it's less effective on muggy days. For a sealed room you still want a mobile air conditioner.

Frequently asked questions

Do air coolers actually work in a heatwave?

They help most in dry heat: evaporative cooling can drop the air a few degrees and the breeze adds to the effect. In very humid weather they cool less because the air already holds a lot of moisture.

Air cooler vs air conditioner — what's the difference?

An air conditioner actively refrigerates and dehumidifies a sealed room but costs more and uses more power. An air cooler only evaporates water to cool the air slightly, is far cheaper, and needs no exhaust hose.
