Rated 4.1 out of 5 by 347 reviewers.
Rated 5.0 out of 5.0 by Long Lasting Value This 20 inch box fan is light weight and durable. I have used for over a year now and it still works perfectly. Also nice is it still looks brand new even though I leave it outside most of the time in Southeast Florida where the salt air usually makes everything rust in no time. For the value price of this fan, you can't beat it. I do have heavier duty fans when I need to move a lot of air, but this light weight, portable fan is just right when you just want to move some air. We use it a lot out by the pool and spa just to add some additional air movement to the ceiling fans. And it is so quiet that we often forget to turn it off when we come in. Everyone should have one of these box fans for general use. It also fits nicely in an open window to help blow a breeze through the house when it isn't 95 degrees outside. Excellent buy for the money. June 14, 2015
Rated 4.0 out of 5.0 by Fan is a great value!!! 1st things 1st....I have purchased 10 of these box fans over the last 2 years. I would recommend this fan for the Price and as long as they stay on the ground they are great. Although if you give this fan to a person(employee) and it falls off a table or a trash can(somwhere between 28" and 40" off the ground) the blades on the inside of the safty grate break off at the seam like a rotten twing. In the buniness we refer to this as "U.E." or "User Error." sooooo, other than that, these are great fans for moving air. Enjoy. I have seen this happen twice now. I need to switch to another type of fan. September 2, 2015
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 4.0 out of 5.0 by Good quality fan I bought this fan to replace a similar one of a different brand that broke after it was knocked over (still not sure why that would have caused it to not work anymore). The layout of my apartment is such that a lot of dead air gets stuck in areas further away from the windows so having a box fan is the only effective way to push air around. I ordered this fan online on Monday and it came on Wednesday! Very prompt and no hassle whatsoever (the package tracking worked very well). It's not the quietest fan although not so bad on the lowest setting, which creates plenty of airflow. On the highest setting it could remind you of a small airplane, but for my purposes there's no need to go to that setting anyway so all is good. It's a product of excellent value. September 23, 2015
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 5.0 out of 5.0 by great, inexpensive fan! This my second purchase of one of these fans. The first one, ran non-stop for 3 years. So why you ask the 5 star rating? Because the first fan as well as the new one, are in my chicken coop. We live in a very fine dust area. My fans have everything happen to them you can picture living in a coop. Feathers, rain, dirt, dust, chickens roosting on them. I figured with the abuse the first fan was taking I'd be happy to get a year out of it, but three, most impressive! They move a good amount of air, and for the price and durability you can't go wrong. July 14, 2015
Rated 3.0 out of 5.0 by This Blows :) Took a while to locate a fan since all stores were sold out during the hot days. I finally found this one and was looking forward to having. Setup was very quick as I only had to remove the two stickers that were attached to the front and back of the fan. This throws plenty of air but it is not quiet....even on the lowest setting. I was planning on use in the bedroom window but it was just too loud. I moved it downstairs to the office and figured the sound of computer audio would did not. I am returning and paying a bit more for a quieter fan. This type of fan is best for areas that have some noise so it can blend in, otherwise you have to live with the constant sound of a small propeller. October 20, 2015
Rated 3.0 out of 5.0 by Box fan with "3" speed (although it works like a 2-speed) This is a box fan. It has 3 settings. Setting 1 (Low) works nicely, almost too loud for a low setting though. Setting 2 (Medium) works almost identical to Setting 3 (High). The velocity and sound of the fan at both 2 & 3 are extremely similar. In fact, this problem pretty much renders Setting 2 useless. It is LOUD on Setting 3. The amount of air it pushes out is what you would expect. The legs that help it stand up are very handy and easy to install. If all you need is a fan to push some air around, this will work. If you're looking to have a fan that has a true 3-Speed setting, this fan probably won't do the trick. October 6, 2015
