At a Glance
The Brentwood Kool Zone F-20SW is the classic box fan done right. A full 20-inch blade pulls serious air while a slim 60-watt body slips into windows, doorways, and corners without hogging space. Three quiet speeds cover everything from background airflow to a strong, room-cooling rush, and the removable grill keeps it easy to clean.
We would rather you know this now than after it arrives.
Will this fit in a window?
Its slim, compact 20-inch body is designed to sit in a standard window or doorway to draw in cool air, though it does not include expandable side panels.
How do I clean it?
The front grill is removable. Unplug the fan, take off the grill, wipe the blades clean, and snap the grill back into place.
Is it quiet?
All three speeds are tuned for quiet operation, so you can run the low setting through the night without a distracting hum.
Does it use a lot of electricity?
No. The 60-watt motor delivers strong 20-inch airflow while staying efficient, so it is easy to run for hours.

Good but noise
Is a very nice size ,strong built But very noise Work very well I wish it was more quiet
It’s a fan
Does the job of a box fan but it is LOUD. Even at setting #1. I needed a fan so it’ll do.
Good deal!
Loving it so far
Great fan, but loud at full speed.
Great fan, works just fine. At full speed it can get quite loud though, so you have to turn it down for quieter operation.
Works well
Does the job - I use it in a box window to vent hot air out the top of our house. A little loud at the highest settings but that's probably to be expected.
