FAQ

• How big a room can this air cooler actually handle?

  This model is most effective in medium‑sized spaces, roughly 20–30 m². It’s designed to circulate cool, moist air through a larger tank and strong airflow.

• How does it cool the air, and is it different from an AC?

  It uses evaporative cooling: warm air is pulled through a wet pad, water evaporates, and the unit pushes out cooler, moistened air. This works best in drier climates and will slightly increase room humidity, unlike a compressor AC that actually lowers air temperature.

• How often do I need to fill the water tank?

  With a 40 L water tank, this cooler runs longer between refills compared with smaller models. How often you refill depends on the heat and humidity, but the large capacity means hours of continuous operation before needing a top-up.

• Can it make a noticeable difference on the hottest days?

  People talk about evaporative coolers making a room feel more comfortable rather than drastically dropping the temperature by many degrees. In very hot and humid weather, performance can feel limited since the process adds humidity rather than removing it.

• How loud is it? Will it disturb sleep or work?

  It runs at about 50–55 dB (think soft conversation), which is on the quieter side for these devices.

• What are the control options like?

  You get three fan speeds, 360° oscillation, a digital display, and a remote control so you don’t have to be right beside the unit to change settings.

• Does this unit actually add moisture to the air?

  Yes. One of the cooling effects comes from evaporation, which means moisture is delivered into the airflow. That’s great in dry environments, but it can feel humid if your room is already moist.

• Is it easy to move around?

  The cooler has caster wheels, so moving it between rooms is simple — handy if you want a cooler breeze in the living area during the day and in the bedroom at night.
