DO NOT BUY - third fan extremely noisy relative to the other two, entire unit died 4 months after purchase. Seeking refund/replacement.

2 fans out of 3 not spinning after 4 month of use

for 3 fans the performance on this unit is horrible. would make no difference on the room at all.

Bottom Line: Moves very little air on high, and not at all quiet on high. Not a speed control but a bogus fan control. Meaning Low has one fan rotating, Hgh has all three fans rotating. Does not have electric reverse. The quality does appear to be good, but on low it is silly worthless, and on High it barely pulls smoke from a cigar.

It doesn't cool

It was too small of a fan to put in the window

it shouldent even get 1 star!!! piece of junk. the middle fan went out in less than 6 months and the the right fan went out in under a year!!! total junk i went back to the old fan i had replaced it for this supposed good fan that is complete junk threw it away. big waste of money

It claims to be multi speed exhaust fan but when it is set to lower speeds the other blades stop turning and the air that is exhausted just comes back through the opening of the blades that are not turning. What a poor design!

This fan is not strong enough

This is hardly a "Whole House" window fan! It barely moves air from one room! For SIXTY BUCKS one would expect a window fan to do a MUCH better job moving air (and I use it strictly as an exhaust fan). Perhaps it's better with fresh air intake, but because it's marketed and designed as dual-use, this is how I am rating it. Whole House? Complete lie and false-advertising, plain and simple.
