Head to head
Choose an evaporative air cooler for a localised water-cooled breeze with no exhaust hose; choose an air conditioner when you need active heat removal and can vent the exhaust.

Actively removing heat from a room
The verdict
The Pro Breeze cooler uses a water tank and the manufacturer says its air coolers do not require external ventilation.
A portable air conditioner uses an exhaust hose to release heat outside; the De’Longhi listing identifies it as an air conditioner.
Evaporative cooling adds moisture to airflow, whereas the air-conditioning model’s stated function is cooling with heat exhausted outdoors.

Common questions
No. An evaporative cooler moves air over water to create a cooler-feeling breeze, while an air conditioner removes heat from the room and releases it outside.
An air conditioner is the category to choose when you need active temperature reduction and can vent hot air. An evaporative cooler may suit local airflow where a hose is impractical and added humidity is acceptable.
It does not need an exhaust hose, but ventilation can help avoid stagnant, humid air. Follow the specific manufacturer’s placement advice.
An evaporative cooler does not provide the same controlled temperature reduction as an air conditioner. The products use different mechanisms, so select based on the outcome you require.
