Our verdict
This is the blower we’d pair with a dehumidifier once the water is out of a basement. Lasko rates it at up to 289 CFM over three speeds, and the head pivots, so you can aim air low across a wet floor, up a damp wall or at a ceiling. It weighs 7.52 lb, has a 10 ft cord and is ETL listed.
Two outlets on the housing let you run a second fan or a tool, behind a 10 A breaker you reset by unplugging the extra load and pressing the button. It is a drying tool, not a cooling fan: Lasko lists 52.4 to 59.3 dBA. The one-year warranty is valid in the US and Canada. Pair it with a pump dehumidifier such as the Frigidaire FHDP5033Y1 from our dehumidifiers and drying fans.
Using it safely after a flood
Safety: don’t walk into standing water or plug anything in near it while the power is on. If water is near the electrical panel or outlets, leave the basement, ask your electric utility to cut the power and have an electrician check before it goes back on.
Lasko’s manual says not to use the fan outdoors, near water or in wet locations, and to avoid extension cords, power strips and cord-connected devices; never run more than one fan from a single extension cord. Pump out and mop up first, then use it to move air over damp surfaces. Our flooded basement guide covers what to do before drying starts.
If the fan stops, switch it off, unplug it, leave it 10 to 15 minutes and plug it straight into a working outlet. Vacuum the grilles with a brush attachment; the motor is permanently lubricated.

Lasko U12104 questions
Can I use the Lasko air mover in a flooded basement?
Not in standing water. Lasko’s manual says not to use it near water or in wet locations. Get the water out and the floor safe first, then use the fan to move air over damp floors and walls, ideally with a dehumidifier running.
Why have the outlets on the Lasko air mover stopped working?
The 10 A breaker has tripped because a plugged-in device drew too much current. Unplug that device and press Reset next to the outlets.
Does an air mover replace a dehumidifier?
No. A blower helps wet surfaces dry by moving air over them; a dehumidifier takes the moisture out of the room’s air. Run them together, with doors and windows closed.
