The summer heat can be unpredictable, which is why you need a multi-functional air conditioner unit to match. This HOMCOM 9000 BTU Mobile Air Conditioner featuring a 4 in 1 design does four jobs - cools, ventilates, dehumidifies and has a sleep mode. It switches between keeping the area at a specific temperature, blowing the fan around, drying the moisture out of the air, and gently increasing the temperature every hour. The sleep function gradually increases the temperature by 1°C every hour. The portable aircon unit is suitable for use all day long and in different climates. It automatically stops when the tank is full, safely preventing it from overfilling and causing damage. A 24-hour timer allows you to set a specific running time, especially when sleeping. EER A grade is perfect for saving electricity. This mobile air conditioner features an on-unit LED screen and comes with a remote. The sleep mode can only be set up with the remote. Control requires 2 x AAA batteries (not included). The removable air filter keeps the air hygienically clean.
