Lasko EcoQuiet S18705 Review: An 18-Inch DC Pedestal Fan with 12 Speeds

Updated October 22, 2026
The Lasko EcoQuiet S18705 is an 18-inch pedestal fan with a DC motor. The listing gives 1800 CFM on 42 watts, 12 speeds and an 8-hour timer, and Lasko covers it for 2 years. It has a 4.2 out of 5 average from 89 ratings among the pedestal fans we cover.
Our Verdict
The EcoQuiet is the fan to buy if you want a full-size 18-inch head without an AC motor’s power draw. Lasko says it is over 60% more energy efficient than its AC fans, and its 12 speeds split into turbo, circulation and whisper quiet groups.
It costs more than Lasko’s AC Cyclones and has a smaller ratings base.

Efficiency
The DC motor draws 42 watts while the listing gives 1800 CFM, close to Lasko’s AC Cyclones that draw over 100 watts. Lasko calls it over 60% more energy efficient than traditional AC fans.
That makes it a sensible choice for a fan that runs all day.
Speeds and Comfort
Twelve speeds are split into 4 turbo, 4 air circulation and 4 whisper quiet settings, and the timer runs up to 8 hours. Widespread oscillation and a tilt-back head spread the breeze.
The height adjusts from 42 to 52 inches.
Warranty
Lasko covers the EcoQuiet with a 2-year warranty, twice its usual 1 year.
Placement Tips
Set a DC circulator a few feet from where you sit or sleep and aim it across the room rather than straight at you. Circulators work best when they keep the whole room’s air moving, so angling the head slightly upward often feels better than a direct blast.
If you run an air conditioner, place the fan where it can push the cooled air into the rest of the room. In winter, the same fan can spread warm air from a heater.
Running Costs and Care
DC motors draw little power, especially on the lower speeds most people use at night, so running the fan for many hours a day adds only a small amount to an electric bill.
Dust the grille and blades every few weeks during the season. A clean fan stays quieter and moves air more efficiently, and most circulator grilles come off for cleaning.
How It Compares
Against the Cyclone 1885, the EcoQuiet uses far less power and adds 9 more speeds and a longer timer, at a higher price.
Against DREO’s TurboPoly Fan 512, the Lasko has a larger 18-inch head, while the DREO is more compact with 120 degree oscillation and a bigger ratings base.
