How loud is the Midea FB5016H on high?

Box fans of this size are audible at the top speed; expect a steady rush of air that some people find hard to sleep through. The lower speeds are quieter and better for a bedroom.

Does it oscillate or come with a remote?

No. It is a fixed-direction box fan with three speeds and manual controls only. You aim it by turning the whole unit.

Can I put it in a window?

Yes, its flat box shape sits well on a window sill or in a window frame to pull in outside air or push hot air out. Check that the sill is wide and flat enough to hold it securely.

How much air does a 20-inch box fan move compared with a smaller fan?

A 20-inch fan pushes more air over a wider area than 10- or 12-inch desk fans, so it cools a whole room rather than one seat. It uses more power and takes up more space.

Dust collects on the front and rear grilles and the blades. Wipe the grilles with a cloth or vacuum them; deeper cleaning of the blade takes a little disassembly.

Shoppers who want strong, simple airflow for a room, window or workshop and don't need a remote, timer or quiet operation. If silence matters, a tower or DC motor fan is the better fit.
