  •       The Number Of Fan Speeds

There is an incorporation of a fantastic fan to deliver ultimate performance in eliminating moisture from the surroundings. This fan can be operated at 2 different speed levels according to the user’s needs.

Although these speeds are not clearly mentioned as “high” and “low,” you will find other light indicators for them in the control panel of the unit. Manufacturers refer to “high” fan speed by “turbo” illuminated indicator.

On the other hand, the “low” fan speed is usually the normal speed and noticed by the “turbo” indicator light not being illuminated.

You can easily switch from one speed to another. However, there is no great difference between both speeds, plus you might find the unit noisy at high speed. Comparatively, the “low” speed is silent but takes a bit longer to remove the moisture.

Still, it is a relatively quieter option when compared to other models on the market. The noise level measures only 53.3 decibels, which is almost the same as the sound of the dishwasher.

  •       Timer

Since the tank size is relatively smaller, the water capacity is low, and you have to empty the tank on a frequent basis. This issue is not faced by users of units with relatively larger water tanks.

  •       Poor Drainage System

The drainage system of this unit is the major negative. You have to incorporate an adapter for proper functioning. However, the adapter and even the screws tend to lose after a period of time. This will lead to a potential risk of leakage.

Moreover, you might need a professional for its proper installation. An adapter and professional help will ultimately result in additional costs.


  •       Low-Quality LED

The LED display incorporated in the unit is not made from fine materials. Therefore, there are certain issues of clarity.
