If you have two windows, the best thing is cross ventilation. Since hot air rises, you need to open the TOP window a crack...so that the air can escape. Then you want cooler outside air in, which you can use a fan for, or just open the BOTTOM of the other window.

Another idea is to freeze some water in empty milk jugs (do a couple so that you can rotate) and put a table in front of the fan (blowing in, of course) at a level so that you can set a frozen water bottle in front of it so the air blows on it. You'll have to set the jug in a tray because the condensation will ruin your table.

Stay cool.

ya, they are great

Yes

I run mine 24-7 sucking air out...

I am thinking about purchasing the Lasko 2138

which is a twin window fan

I want my room to feel ventilated..I have a ceiling fan but it doesnt do anything but move the stuffy air that's already in my room
