They are not going to balance a floor to floor problem, but can help a room problem.

Thanks, reading up on these threw floor fans now. I like these!

Look into these fans. I bought the 8" and couldn't be happier. The fan runs just about 24/7 with minimal electric use. Not too noisy either. A bit pricey, but you get what you pay for! Best of luck
