Rated 4.1 out of 5 by 224 reviewers.
Rated 5.0 out of 5.0 by Best value for the price. No assembly needed. You just pull it out of the box and start using it. I needed it for a DIY HEPA air purifier project. I mounted the 20x20x1 HEPA filter to the fan and it was done. October 29, 2013
Rated 5.0 out of 5.0 by This item works well and seems to be durable for the price. This box fan does everything I want for a very good price. It moves air nicely and has held up well, even after it tumbled off a counter. June 7, 2014
Rated 4.0 out of 5.0 by A good fan and everyone needs a fan. Lightweight but sturdy, Very quiet for the amount of air it circulates. I have a need to have air circulating around me to control my chemotherapy "Hot Flashes" and this fan has thus far preformed very well. September 2, 2014
Rated 1.0 out of 5.0 by Total Junk. Very Disappointed Fans were shipped to my home and the handle was broken on one, and both fans were bent so badly that the fan blades were making contact with where the handle attaches on the inside of the fan, as well as the grill. Total junk. Home depot should be ashamed April 27, 2015
Rated 4.0 out of 5.0 by Puts out cool air; loud For box fan, puts out cool air but I think it's a little loud. I do not use these in my bedroom when I am sleeping. I live in an old house formerly a carriage house. Main room is huge--almost 50 ft long. Have 1 in each corner at opposite ends to keep cool air circulating. May 13, 2014
Rated 5.0 out of 5.0 by house fan good price, light weight and does the job... durable good for outside or inside April 10, 2015
Rated 3.0 out of 5.0 by Box fan The fan works OK but it just doesn't move enough air. I would like to have a bigger unit. April 8, 2015
Rated 4.0 out of 5.0 by Great value It's a box fan. It does what it's supposed to do. I purchased from home depot online because they had the best price and free shipping. You really can't go wrong with those two factors. September 24, 2013
