Customer Reviews

20 in. 3-Speed Weather Shield Premium Plus Box Fan is rated 3.9 out of 5 by 15.
Rated 4 out of 5 by from Better than the regular "Weather Shield". This is an inexpensive box fan, but it works great as we have no A/C. [] We stack two of them in the window w/o the legs and secure them with a bungee. [] We need one fan per 100 sq ft on hot California days. [] I like the larger selector knob. [] It is only a couple of watts more than the original. [] If you like box fans, get the WEATHER SHIELD PREMIUM PLUS. [] But remember, this is a machine and you should not drop it. [] As usual, The Home Depot ships quickly for only a few dollars, or free.

Rated 5 out of 5 by from Excellent value for the money! This fan moves a lot of air and the three speeds are handy also. It is fairly well made and with care should work through a long hot summer (at least). It is light and easy to move around and I added 2 attachments and have it hanging from my shop ceiling and remove it when I am through working there so it won't get dirty. For the price it is a good buy.

Rated 5 out of 5 by from Better than other 20 inchers This fan really moves the air and requires the included feet to remain upright. Stuck in a window it keeps my second floor nicely ventilated. Even on low speed the performance outshines two different 20 inch fans I have. While I can't really say the lowest setting is quiet it does provide some nice white noise at night.

Rated 4 out of 5 by from Great window fan. This fan is very good it's far more durable and well built then the lower end Lasko fans(which are still great by the way). It's a much more solid fan and just feels like it's much higher quality and all for only a little bit more money then the baseline fan. It moves much more air through it and is actually not all that loud even on it's highest setting(it's not whisper quiet but it's surprisingly quiet for how much air it moves) The only real problem I had is that the fan is a bit thicker then the lower end models which is likely the reason this one is so solid. But because of this it doesn't fit my window as well as it could but it's still not that much of a problem as windows vary from place to place. Overall a very solid window fan and a great value for only a little more compared to the baseline model.

Rated 5 out of 5 by from This fan has the great features I need. I'm using this fan to circulate air and cool my greenhouse. This multiple speed fan with it's weather-secure feature is exactly what I needed for my purpose since the speed can be varied to match the seasonal changes.

Rated 3 out of 5 by from Low price but poor quality. The fan works well and is quiet but the whole thing is cheap plastic and will not last for very long. Whatever you do, don't drop it.
