Can it be used in a bathroom?

This question is from Weather-Shield Select 20 in. 3-Speed Box Fan with Thermostat

May 16, 2016
Im looking for a fan i can use in my bathroom window to help with humidity and odors (blowing air outward), and also to blow cool air in at night by flipping it around. I'm only renting this place, which is a small cabin-like house and nearly a century old, so window fans are just about my only options...I'm just concerned about humidity because other standard fans i have tried have deteriorated in functionality within a couple months.

Customer Reviews

Rated 4.6 out of 5 by 22 reviewers.
Rated 4.0 out of 5.0 by Powerful - does what I *expect* a box fan to do I was very impressed with this fan (which I chose due to so many glowing reviews). I have previously used cheap box fans from discount stores, which seem to barely stir the air. This fan is well worth the few extra $, due to its power. On high, I can feel the air flow at about 15-20' away. It's not silent, but the lowest setting is easy enough to ignore at bedtime. Works fantastically as an exhaust fan, as well. I'd like to give it 5 stars, but the power/speed knob shorted out after 3 weeks, during which we mostly ran it constantly - turned the knob *maybe* a dozen times. I'll be exchanging it for another of these, tomorrow. (Since I've seen no other reviews mentioning the knob issue, I'm sure it's just a random defect.) All-in-all, this fan makes a huge difference in an un-airconditioned apartment, whether pulling in cooler air at night or pulling out hot/stuffy air. July 5, 2016
Rated 4.0 out of 5.0 by thermostatic fan The fan moves air with great efficiency. The built in thermostat is an excellent feature. It is a little bit on the loud side during use, which is the only draw back. July 26, 2016
Rated 5.0 out of 5.0 by great service I bought this online unfortunately it took longer then I wanted so I ended up buying it at another store I was not able to cancel the online order so when it came in the service clerk refunded it no problem. Thank you Home Depot. July 20, 2016
Rated 5.0 out of 5.0 by Looks great and works even better I have had this fan for a little over a month now and its by far the best box fan I have ever owned! July 22, 2016
Rated 5.0 out of 5.0 by Great Fan! I love this fan! I use this for a soft noise at night, it moves air wonderfully too! The thermostat will turn the fan off when it gets too cold which is really nice on cool nights! The fan sits in my window and a couple times it got rained on. (oops) I glad the weather shield has kept my fan running smoothly! The fan even looks nice with the stainless steel sides! June 29, 2016
Rated 1.0 out of 5.0 by Survey for the fan that I purchased When I receive a product that has a black wire and a blue plug that just does not appear right. This either means the fan was tampered with or specially designed for me - just like the black and blue back brace that I sent back to Tabeek Medical in Lincoln Park, NJ Have a great day! June 14, 2016
Rated 4.0 out of 5.0 by Modern Day Box Fan Wanted a Box Fan in Black to replace my very old Lasko Box Fan. My old fan is still in good working condition but my decor has changed and black fell into the background. This newer model is not as stable on the floor as the old fan without it's feet. I only hope this fan lasts as long as my first Lasko. June 9, 2016
Rated 5.0 out of 5.0 by Light Weight but Solid I bought this fan online, picked it up within a few days at local Home Depot. Fan is being used to keep air circulating around kilns in the art studio. Thermostat control on/off keeps digit controls of kilns cool and operating properly. Thermostat is appreciated, keeps the fan running only when needed. Great buy! May 24, 2016
