Consumer warnings issued over fraudulent mini air conditioner advertisements

Consumers are being warned about deceptive online advertisements for ‘mini air conditioners’ that mimic legitimate editorial content. These advertorials often use fraudulent imagery, including the logo of ‘Stiftung Warentest’, to create a false sense of authority and independent testing. These ads direct users to shops featuring fabricated customer reviews to sell compact cooling devices.

In a related discussion on cooling efficacy, physicist Werner Gruber clarifies that electric fans do not lower room temperatures. Instead, they merely circulate existing warm air. While fans can provide personal relief by accelerating sweat evaporation on the skin, they do not provide true room cooling. Gruber notes that sitting directly in a strong airflow for extended periods may cause muscle tension in sensitive individuals.
