The Lasko 3723 20-Inch Premium Box Fan is a floor fan that delivers good airflow at a bargain price. Users say it's surprisingly sturdy for a budget-friendly model, despite its slim shape and light weight. However, it's noisier than some fans and the wide grille isn't kid-friendly. Moving it from floor to window can also be awkward because of its poorly designed legs.
Powerful and durable. Most owners say this fan produces a good flow of air. One Amazon.com reviewer calls it "the most powerful box fan on the market," with a maximum airflow of 3,623 cubic feet per minute (cfm) compared to a typical fan's 2,250 cfm. Posts at Viewpoints.com say the Lasko 3723 can cool a large room effectively, although a few users disagree at other sites. One drawback noted at Viewpoints.com is that this basic box fan doesn't oscillate and the angle of airflow can't be adjusted. "If there is more than one person in the room they are fighting to direct the air in their direction," an owner complains.
Users also praise this fan's durability, with multiple Amazon.com reviews saying it lasts for years. "It is the only fan that I have found that is both inexpensive and durable," adds one Viewpoints.com poster. Several owners like that the fan's case is made of steel rather than plastic, but that doesn't necessarily make it sturdier. A couple of users report at Amazon.com that the fan arrived with a dented case, although this didn't affect its function. Others say the Lasko 3723 gave off an acrid smell the first time they used it, but it went away in time.
Easy controls, awkward legs. Setting up this fan would be a simple plug-and-play operation if it weren't for the legs. While the fan's case is made of steel, it comes with a pair of plastic "feet" that attach to the frame so it won't scratch floors. At Amazon.com, one user says, "tried and tried but couldn't get one of the feet into its slot in the bottom of the sheet metal housing." This isn't a problem if you want to keep the fan in a window, owners explain, but if you plan to move the fan from floor to window, it's a nuisance to keep taking the feet on and off.
Aside from this, reviewers find the fan easy to operate, with just a single knob on top to turn it on and adjust the speed. One Amazon.com user finds it annoying that the fan goes directly from off to high speed and then gets lower, but this is standard for box fans. Others note that it's easy to remove the fan's grille for cleaning.
High speed can be loud. While reports differ, the general consensus is that the Lasko 3723 is fairly quiet on low speed and equally loud on high speed. Just how loud is a matter of dispute: One Amazon.com user says the highest setting "sounds like you're trapped inside an aircraft" while another says, "it's not too strong and you'll never hear anyone yell, 'turn that fan down, it's blowing me away!'" Overall, reviewers seem to consider the fan's noise level reasonable for its size and price. Some even like that the white noise helps them sleep at night.
Utilitarian looks. The Lasko 3723 is about as basic as it gets. Some users complain that the light-colored case shows dirt easily, although cleaning it is a snap. The fan is fairly lightweight and has a very narrow profile, which makes it easy to lift into a window frame but also makes it likely to tip over when sitting on the floor. Owners' most common gripe about the fan's design is the width of the front and back grilles that won't keep out a curious child's fingers.

Most say it produces good airflow, isn't too loud and holds up well. However, some owners find it noisy on the highest setting and say the airflow isn't strong enough to cool a large room.
