Who wins in which category?
| Category | Winner | Reasoning |
|---|---|---|
| Cooling output | De’Longhi PAC EX105 | 10,000 BTU / 2.4 kW real compressor cooling vs. 80 ml/h of spray mist; only the De’Longhi really lowers the room temperature |
| Room size | De’Longhi PAC EX105 | up to about 40 m² vs. spot cooling; the monoblock cools whole living spaces, the CosmartAir only the immediate vicinity |
| Placement | CosmartAir 4-in-1 | no exhaust hose vs. monoblock with 1 hose; the CosmartAir needs no window, just set it up and fill it with water |
| Extra function | CosmartAir 4-in-1 | integrated ultrasonic humidification + 120° oscillation vs. cooling/dehumidifying/ventilating; the CosmartAir humidifies the air, the De’Longhi dehumidifies it |
| Energy efficiency | De’Longhi PAC EX105 | Energy class A+++ with R290 vs. no class stated; the De’Longhi delivers the lowest electricity costs per real hour of cooling |
| Price | CosmartAir 4-in-1 | from €143 vs. from €480 |
Which one is right for you?

If you only want a light, hoseless refreshment with humidification for a windowless room, the cheap CosmartAir 4-in-1 will do, but it does not replace an air conditioner.
