Lasko - 20" Weather-Shield Performance Box Fan, 3-Speed (3720)

Good quality fan. Sturdy build and not too noisy.

This Lasko 20" box fan is powerful but quiet on low speed. I have one that is more than 15 years old and still works well. During a heat spell, I bought a second one, and it is just as effective. I highly recommend the Lasko 20" box fan for quiet but effective cooling.

I have this thing on 15 hours a day, in use for a CR box. It reliably runs at any speed.

This fan fell apart immediately. The handle broke, it started rattling, and all three speed settings now move as slow as speed 1. It falls over easily even with the feet installed, but the feet broke on mine so it’s basically useless! This fan is an affront to the environment, your wallet, and the Lasko brand. Shame on the seller and shame on the company for making such a garbage product and pricing it so highly! This fan wouldn’t even be acceptable at 15 dollars!! When I requested a refund the seller said “the best I can do is give you 50% back”. Shame! Shame! Shame!! Update: I have continued to use it, and now it's SMOKING. This thing is a FIRE HAZARD!

I bought 2 of these fans. I use them everyday, mainly to sleep with...almost as a sound machine. They also work great for their main use...keeping my house cool and myself cool, I don’t use my air-conditioning unit...just open-windows and fans. I spent an absolute total of $78.40 for 2 of these, and overspent by $10.40. Long story, but I should not have spent more than $68.00 total for these 2 fans...Amazon and 3rd-party supplier / seller got a better deal than I did. The fans work great, no issues there, everything is swell...Lasko makes great quality products. I was not happy with the packaging...the 2 fans only came in the actual fan box themselves (see photos), no additional packaging...they easily could have been damaged in the delivery process...no (and I mean zero) additional packaging or boxing, unbelievable. It all worked out though, a couple very small manufacturer scratches on the frame metal, nothing too major at all. I recommend this fan, but paying more than $34.00 total per fan, look elsewhere...at least give it the due diligence to hinder any buyer’s remorse. Great box fans though, I recommend this exact box fan.

I am partial to this brand and have had good luck with longevity of products. This fan is quieter than the older models and very efficient at moving air. Easy to use and quite sturdy. Would recommend this product as it is for the floor a window or on a shelf.

Fan was sturdy, nice looking but reading the fine print on sticker, not supposed to be in window, bathroom or near water. Intended to use in attic window for exhaust at night, and not intending to have to bring in whenever raining. Not sure how it was to be 'weather shield'...returned it after trying unsuccessfully to contact company for clarification. Not willing to take a chance, as sticker made it clear that there would be no responsibility for shorting out, etc. Otherwise, using inside room or to dry basement, etc would be fine , I think. [placement of button on top would have made adjustment necessary if in window frame, as well]

Got it free shipped within 24 hours. Just simply plugged and the fan started running. Just make sure the fan is on a window with back facing the open window. Three speeds good enough to cover a room of 10x12 ft. Quality is good and sturdy.

Seems sturdy and might have good airflow, but it was so loud on the lowest setting, I returned it. Customer service was fairly good, though.
