Check whether your model accepts ice
Read the manual before adding ice. Some coolers have a separate ice compartment or supplied packs; loose ice in the reservoir may obstruct a pump or exceed its fill limit.

How to Use an Air Cooler with Ice and Water Safely
Use clean water to the marked fill line, then add ice only if your manual allows it. Keep the cooler level and ventilate the room.
Fill the reservoir with clean water
Switch off and unplug the appliance before filling. Use the marked maximum line and keep water away from the control panel and electrical connection.
Add the supplied cooling pack if directed
Freeze and place any included pack in the designated compartment. Do not assume extra ice improves performance, and never force a pack into the water pump area.
Set airflow and open a window
Place the unit on a level surface with its inlet and outlet clear. Evaporative cooling adds moisture, so some ventilation helps prevent the room becoming uncomfortably humid.
Empty and clean after use
Follow the maker’s cleaning schedule. Disconnect power, drain stagnant water and dry accessible parts; never immerse the electrical body.
Common questions
Questions before you buy
Should I put ice directly into an air cooler water tank?
Only if the model manual explicitly permits it. Use a dedicated ice compartment or supplied pack when provided.
Do I add ice before or after filling the tank?
Follow the manual’s sequence and fill limit. Usually water is added to the marked line before placing a designated cooling pack.
Should windows be open when using an evaporative cooler?
A little ventilation is generally useful because evaporation adds moisture. Avoid sealing a small room while the appliance runs for long periods.
Can I leave water in the cooler between uses?
For hygiene, follow the manufacturer’s directions; draining and drying the reservoir when it will sit unused helps avoid stale water.
