How effective are evaporative air coolers?
According to the US Department of Energy (DOE), an evaporative cooler can successfully reduce the ambient temperature by 5 to 15 degrees—but even the DOE is quick to clarify that this process works only in areas with low humidity.
What is the difference between an evaporative cooler and an air conditioner?
The main difference between the two is that an evaporative cooling system uses water to cool air and then directs it through your home while air conditioning (split systems and ducted), relies on refrigerant gasses and a chemical process to cool the air.
Do evaporative coolers cool a room?
These portable evaporative coolers work well in moderate climates, but may not be able to cool a room adequately in hot climates. Room evaporative coolers are becoming more popular in areas of the western United States with milder summer weather. They can reduce the temperature in a single room by 5° to 15°F.
What is a evaporative cooler used for?
Evaporative coolers are designed to circulate evaporated water through the air. This cools and adds moisture to the room or surrounding area and is a cost-efficient climate control method. Evaporative coolers use very little energy, making them an environmentally friendly option for many homes.
Is air cooler worth buying?
Yes, air coolers are worth buying. Evaporative air coolers use a fan to draw in warm stale air, where it passes over water-moistened pads. This immediately cools the air. Then evaporative coolers release this cool moisturized air into space.
Can you leave evaporative cooling on overnight?

Do you need to open windows for evaporative cooling?
For an evaporative air conditioner to work effectively, some windows or outside doors must be open, or some other form of ventilation provided. The best approach is to open the windows or outside doors that are the furthest away from the air conditioning vents or ducts.
Is an evaporative cooler better than a fan?

Can you use an evaporative cooler indoors?
While there are some environments conducive to evaporative cooling use in an enclosed building, the cooler is not going to operate at its highest efficiency. In some instances, running an evaporative cooler in a closed environment could make the room or building warmer by increasing the humidity level.
Can I use air cooler in closed room?
You can use your air cooler just like a fan in a closed room by turning off its water pump. If you are thinking of using an air cooler in a closed room then it is advisable that you use it just like a pedestal or table fan. Due to evaporation the water in liquid form turns into vapor causing cooling.
How much water does an evaporative cooler use per day?
Evaporative coolers use both electricity and water. How much water is used depends on the humidity of the day and the fan speed that the unit is set to operate on. A portable unit might use up to 4 litres per hour while a central system could use as much as 25 litres per hour.
