The verdict
An air cooler and AC solve different problems. Select evaporative cooling for a ventilated space where a cooler airflow is enough; select AC when room cooling is essential and exhaust installation is possible.
No exhaust hose: Evaporative air cooler
An evaporative cooler generally avoids an exhaust hose but still needs appropriate ventilation.
Active temperature reduction: Daewoo 3-in-1 Portable Air Conditioner with Fan & Dehumidifier, 5000 BTU
AC uses refrigeration to remove heat and expels it outdoors.
A humid room: Daewoo 3-in-1 Portable Air Conditioner with Fan & Dehumidifier, 5000 BTU
Evaporative cooling adds moisture, making it a poorer fit when humidity is already high.

Common questions
Questions before you buy
How does an evaporative air cooler compare with AC?
An evaporative cooler moves air across water and relies on evaporation; AC uses a refrigeration cycle. They have different effects on room temperature and humidity.
Does an air cooler need an AC hose?
An evaporative cooler usually has no exhaust hose, but it needs suitable ventilation. A portable AC generally needs an exhaust route to discharge heat.
Is portable AC better than an air cooler?
Portable AC is better suited to active room cooling; an evaporative cooler may suit a ventilated space where a directed breeze is enough. Consider humidity and installation.
Can an air cooler work with windows closed?
Follow the manual, but evaporative coolers need air exchange to manage the added moisture. A closed room can become increasingly humid.
Does AC add humidity like an air cooler?
A conventional AC generally removes some moisture as it cools. An evaporative cooler adds moisture through evaporation.
