Customer Questions & Answers

Can this be wall-mounted?

I am looking to mount it at a downward angle.
Asked by: Katt
This fan is designed to sit on the floor. Unfortunately, no easy way to mount to the wall.

CFM?

Asked by: valuedcustomer
But is it the same fan? That one has complaints of being noisy. This one is supposed to be super quiet. One would suppose that would change the CFM. Does it?

Also appears to be well constructed. I didn't give it a 5 because the handle feels so cheap. Every time I pick it up, I think the handle is going to break. I have only owned the fan for 2 months. Hopefully, I will just as happy in 5 years.

This box fan work nicely at moving large quantities of air, but is on the noisy side by the time it's set on 3. The only problem I experienced was the insertion of the plastic feet that help stabilize the fan when it sits on the floor, they're a real bear to insert into the opening in the housing (I observed this on each of the 3 fans I had ordered).

Perfect fit, held in place with elastic cord. With a window open on the opposite side of the house it ventilates the house at night or any other time it's too hot inside and cooler outside. The weatherproof feature is a nice touch. Exactly what I needed.

The sensitive alarm in our apartment building has often brought the local fire department to share our quick-seared steaks with us. A simple, effective solution to our kitchen exhaust problems.

Rated 5 out of 5 by from Good performance and rain resistant.. I needed a fan to keep my rabbits cool in this Summer heat of 100+. I had already gone thru 2 other non weather protected fans before I found this one. Works perfectly with no issues after a couple showers. Going to buy another one.
