Verdict

The TROTEC TTK 66 E is a powerful condensation dehumidifier for rooms up to 50 m² (125 m³), removing up to 24 litres per 24 hours with 168 m³/h airflow and 440 W input. It has a 35-85% hygrostat, four operating modes including laundry drying and temperature-dependent comfort control, an ioniser, a 3-litre tank with overflow protection, a 24-hour timer, auto-restart, and castors with carry handles. Its 46-48 dB(A) operating noise may not suit sensitive bedrooms, it has no app control, and the relatively small tank can require frequent emptying without a drain hose.
