FAQ

1. Does an air cooler actually cool the room?

Air coolers do provide effective cooling! Their core principle relies on water evaporation to absorb heat, delivering much cooler air than standard fans while being suitable for diverse scenarios.

2. Is it necessary to pour water in an air cooler？

Yes, adding water to the  air cooler is a crucial step that directly enables its cooling function.Without water or with insufficient water, the device functions merely as a regular fan—only circulating air without any cooling effect.

3.Should I close the window when using an air cooler?

Yes, we suggest keeping windows/doors slightly open when using the air cooler. It helps circulate air, expel moist air, and improve cooling efficiency. For small rooms, a 5-10cm window gap works; for large spaces, ensure partial ventilation. Avoid sealed spaces—this ensures the cooler performs at its best!
