Extraction Rate
This dehumidifier has an extraction rate of up to 21 L of moisture per day.
This makes the unit great for larger spaces, such as living rooms, shops, or offices. However, you will need to connect the unit to a drain if the room’s moisture level is very high and you want to lower it quickly. Otherwise, you will have to empty the water tank a few times each day.
Once the humidity level falls back to normal levels you can just use the water tank to collect water. The continuous drainage feature is handy for less visited areas such as sheds, garages, boats and caravans.
Filter And Water Tank
The filter is located behind the front grill. It’s easy to reach and to remove, and you should clean it at least once every month. You don’t have to change the filter. You should clean it with a damp cloth and let it dry completely before putting it back.
The water tank has a capacity of 3 L. When the tank is full, a sound notification will make 8 beeping sounds and a light indicator will flash.
The unit will automatically turn off when the water tank is full. The water tank has two handles for easier manipulation. You should be careful when removing the tank because the water rises near the top.
