Customer Questions & Answers

Can this be wall-mounted?

I am looking to mount it at a downward angle.
Asked by: Katt
I do not think it is meant to be put on a wall and is best if placed in a window for air circulation.

How much energy does it consume?

I need the wattage, voltage, and amps.
Asked by: Pichi17un
I really don't know but I think it only costs pennies to operate. Details are in the product information on line.

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?

20 in. 3-Speed Weather Shield Performance Box Fan is rated 4.4 out of 5 by 61.

The description says, "Patented, isolated Weather-Shield motor for worry-free window use." The fan is shipped with a sticker that clearly says it is not for use in a window. I will not purchase from this manufacturer again since they choose to play ridiculous liability games. Home Depot should stop selling this brand since HD is typically good about being clear about products and standing behind their sales.

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.

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.

Rated 3 out of 5 by from Very Loud While this fan certainly serves its purpose in keeping the room cool, it is very loud. Forget about watching tv or having a "whisper moment", you definitely will not hear either.

Rated 5 out of 5 by from Meets the need Had purchased the less expensive model but it was too noisy for my wife. We have one just like this one that finally gave out so we knew the quality and quietness was there for this model. Fan is quiet and so is my wife.

Rated 5 out of 5 by from Excellent, Durable Fan This window box fan is far and away better than most fans of this type on the market. In the summer, we have our fans running all day and night, in lieu of using the expensive air conditioner. We have at least one fan in each room; in some rooms we have two. It is important to have a product that is sturdy, durable and efficient. These fans last us through at least three, sometimes four, summers. We also run them in some parts of the house during the winter. With the cheaper fans we replace them after a summer and a half. They are more expensive than the fans you buy at certain department stores and other hardware store, but they wind up being more cost effective and reliable than the other. As the other fans wear our, we will replace them with these.
