Where can I buy small window fans?

I love my small window fan I have. It's perfect for when it is warm in the home and cool outside. You get that nice cool breeze coming in when you have the fan in the window. 

I have come across several sites online that have very nice and affordable window fans. I have listed a few options for you below to choose from. I do hope this helps and you find one you are wanting to buy.

The fan I have for my window is Kaz HoneyWell Twindow: I have had mines for three years and I love it.

• Circulate fresh air into any room without exposing your home to the elements

The Lasko Air Director 2135 is the only fan of its kind on the market. This original, patented combination window/floor fan is smart and stylish. For those times when a standard window fan doesn't cut it, the Air Director pivots to send the air exactly where you need it the most. Plus, it works as a powerful floor fan too, making it a great choice for any room in the house!
