Compare the Lasko 36-inch and 40-inch DC tower fans side by side. Learn which size and speed combination best suits your room and comfort needs.
Quick answer
Choose the Lasko 36-inch DC tower fan for smaller spaces or quieter operation, and the 40-inch model for larger rooms where you want more airflow reach and a taller tower profile.
Why height matters for airflow
The main difference between these two Lasko DC tower fans is the height: 36 inches vs 40 inches. That extra 4 inches on the 40-inch model places the fan blades higher, which can help circulate air over a wider vertical area in a medium to large room. In a compact bedroom or home office, the 36-inch model may feel less imposing and still deliver strong airflow up to 50 feet.
Speed and mode flexibility
Both fans offer 12 speeds, 4 fan modes (including a night mode), and 90-degree oscillation. The WhisperForce DC motor on each runs as quietly as 24 dBA. If you plan to use the fan while sleeping or watching TV, the 36-inch model’s slightly shorter height can make the airflow feel more direct at lower speeds. The 40-inch model’s extra height may be better at moving air across a larger room without needing to run at top speed.
Price and value
The 36-inch model is priced at USD 60.99 (catalog comparison price USD 99.99), while the 40-inch model costs USD 67.99 (also compared at USD 99.99). The 40-inch model costs about USD 7 more, which is reasonable for the additional height and slightly larger coverage area. Both include a multi-function remote, 12-hour timer, and a removable Airscreen filter.
Trade-offs at a glance
- Room size: The 36-inch fan works well in smaller rooms (up to ~150 sq ft). The 40-inch fan is better for medium rooms (up to ~250 sq ft).
- Noise vs reach: Both fans are equally quiet at 24 dBA, but the 40-inch tower pushes air across a taller vertical zone, which may reduce the need for higher speeds in a larger room.
- Price difference: The 40-inch model costs USD 7 more. If your room is small, the 36-inch model saves money without sacrificing performance.
