Wood’s continues to deliver test-winning portable air conditioning units. Following high ratings and recommendations for previous models in the Cortina series, Wood’s AC Cortina 12K AirSwitch was named “Best in Test 2025” by Ljud & Bild.

Wood’s AC Cortina 12K AirSwitch has been named “Best in Test 2025” by Ljud & Bild. In the test, the editorial team particularly highlighted the innovative AirSwitch technology, the low noise level and how the air conditioner contributed to a noticeably better indoor climate in the bedroom.
One of the things that impressed the test subject most was that AirSwitch didn’t just cool the air – it also replaced it. In short: Fresh air in the bedroom thanks to the AirSwitch function.
During the test, the AC was used in the bedroom for several weeks. When the outdoor temperature was low enough, the AirSwitch mode could be used all night, providing a cooler and fresher sleeping environment.
Many people avoid using air conditioning in the bedroom because they are concerned about the noise level. But it was precisely this low noise level that became one of the biggest strengths in the test.
In AirSwitch mode, the air conditioning operates at only around 35 dB, which is equivalent to the noise level in a library. Ljud & Bild describes how the quiet operation made a big difference to a good night’s sleep:
“AirSwitch provided a good indoor climate and better sleep; I woke up feeling rested and without a headache.”
For people who find it difficult to sleep when the bedroom gets hot during the summer, this can be a crucial feature.

All portable air conditioning units use a compressor to cool the air, and it is also the compressor that accounts for the majority of the noise. Wood’s AirSwitch works differently. When the outdoor temperature is lower than the indoor temperature, AirSwitch uses the cooler outdoor air to cool the room instead of letting the compressor run continuously. The result is lower energy consumption, lower noise levels and fresher air in the room.

In AirSwitch mode, the unit operates at only around 35 dB, which is equivalent to the sound of a whisper.
In the test, Ljud & Bild also highlighted how AirSwitch contributed to better air quality in the bedroom. The test subject clearly noticed that the air in the bedroom felt fresher in the morning compared to the rest of the home.
In addition to cooling, the Wood’s AC Cortina 12K AirSwitch is equipped with a HEPA filter that captures pollen, dust and other particles, making it particularly appealing to allergy sufferers and those wishing to improve air quality at home.
AirSwitch builds on the multi-award-winning Cortina series from Wood’s. Wood’s AC Cortina 12K Smart Home has also previously received a special recommendation from Ljud & Bild thanks to its efficient cooling, low energy consumption and smart WiFi control.
Common to the Cortina series is high cooling capacity, user-friendliness and a focus on comfort during hot summer days.
