When it comes to noise levels, the Tehanld operates at an impressively quiet 42 dB, significantly quieter than many traditional units that exceed 60 dB. The MERXENG, while also commendable with a noise level of 50 dB, is somewhat noisier than the Tehanld. For users sensitive to noise, such as those with infants or light sleepers, the Tehanld's ultra-quiet operation may make it the more appealing choice.
Energy Efficiency
The Tehanld air conditioner boasts an energy-saving feature, using 37% less energy than standard models and operating at a cost of approximately $0.18 per day. This efficiency is beneficial for budget-conscious consumers.

It also includes adjustable brackets to enhance stability, which is particularly beneficial for renters or those living in older homes.

The Tehanld’s innovative design may provide a more reliable and stable fit for a wider range of window types.
Versatility in Cooling Modes
