Lasko T42951 Review: The Classic 42-Inch Wind Curve Tower Fan
Lasko's long-running 42-inch Wind Curve tower: 3 speeds, 60 degree oscillation, a nighttime dimming mode and a 7.5-hour timer, with one of the largest ratings bases of any fan.

Updated October 22, 2026
The Lasko T42951 is the 42-inch Wind Curve tower fan that has sat in American bedrooms and living rooms for years. It keeps things simple, with three speeds, a remote, a 7.5-hour timer and a nighttime setting, and it carries a 4.4 out of 5 average from 62,990 ratings, one of the largest ratings bases among the tower fans we cover.
Our Verdict
The T42951 is the safe, proven pick for anyone who wants a tall tower fan that just works. Its 60 degree oscillation keeps the breeze on you, the nighttime setting dims the controls and slows the fan for sleep, and the slim body with a carry handle moves easily from room to room. Blue Plug safety technology cuts the power if it detects an electrical fault.
The trade-offs come from its age. This is an AC motor fan with only three speeds, so it is louder and less adjustable than newer DC towers, and it has no auto mode, app or temperature sensor.

Airflow and Coverage
Lasko describes the T42951 as a fan for small to medium living rooms, bedrooms and home offices. The specifications list 262 CFM from a 48 watt motor, which is modest next to the latest DC towers, but the 42.5 inch body spreads that air from mattress height up to a seated person’s shoulders.
Lasko deliberately limits oscillation to 60 degrees. A wider sweep covers more of the room, but it also leaves you waiting longer for the breeze to come back. With 60 degrees, the air returns quickly, which feels more consistent if you are sitting or lying in one spot.
Noise and Sleep Features
The nighttime setting is the feature that makes this a good bedroom fan. It automatically dims the LED controls and lowers the fan speed, so a bright panel and a strong blast do not keep you awake. Pair it with the 7.5-hour programmable timer and the fan shuts itself off after you fall asleep.
Lasko lists 55.4 dB in the specifications, a figure that reflects the AC motor. It is a steady, even sound that many people use as white noise, but it is not as quiet as DC towers rated in the 20s.
Controls and Setup
The remote handles power, the three speeds, oscillation, the timer and the nighttime setting, so you never have to leave the bed. It runs on 2 AAA batteries, which are not included. The same controls sit on top of the fan.
Setup takes only a simple base assembly. The fan weighs 10.6 pounds and has a built-in carry handle, so moving it from the bedroom to the living room is easy.
Safety and Warranty
The T42951 is ETL listed, and its Blue Plug safety technology cuts off the electric current if the plug detects a potentially hazardous fault in the motor or power supply. That is a reassuring feature for a fan that may run for hours every night.
Lasko covers it with a 1-year limited warranty. That is standard for tower fans in this class, though some DC models now offer longer coverage.
How It Compares
Against Lasko’s own 36-inch 2510, the T42951 adds height, a nighttime mode and a slightly longer timer, which makes it the better choice for a living room or a bed with a tall frame. The 2510 is lighter and draws less power, so it suits a dorm or small office.
Against a DC tower such as DREO’s 42-inch DR-HTF018, the Lasko is simpler and louder, with three speeds instead of nine. The DREO moves more air and is quieter on low, while the Lasko wins on track record and plain, easy controls. If you want something in between, Lasko’s own Pinnacle DST100 adds a DC motor and 12 speeds.
Pros and Cons
| Pros | Cons |

| Nighttime mode dims the controls | AC motor is louder than DC fans |
