THE ASPEN 20" Box Fan with Remote AB-20US vs Lasko Weather-Shield 3720 Box Fan

Buy the Lasko 3720 if you want a proven, weather-shielded window fan with a long cord and a sturdy aluminum housing. Buy the Aspen AB-20US if you want a remote control, a lighter fan you can carry with one hand, and the highest airflow in this pair. The Aspen moves more air and is easier to move around; the Lasko feels more solid and is built for window mounting. Owners praise the Lasko's durability and the Aspen's convenience, though some Aspen buyers report the remote pairing is fussy and some Lasko owners find it heavy and loud on high.

  • Choose the Aspen AB-20US if you want remote control, a 6.4 lb body with a built-in handle, and the strongest airflow of the two.
  • Choose the Lasko 3720 if you need a window-mounted fan with a weather shield, a nearly 20 ft cord, and a heavier aluminum housing that reviewers say lasts.

What reviewers say

THE ASPEN 20" Box Fan with Remote AB-20US

  • 4.5 / 52,544 ratings

Ratings are strong at 4.5 out of 5 across more than 2,500 reviews. Owners mainly praise the airflow and the convenience of the remote. Complaints center on noise at the highest speed and on the remote's range and pairing.

What people mention
  • AirflowPraisedOwners say it moves noticeably more air than smaller box fans and cools a room quickly.
  • RemoteMixedThe remote is a common reason to buy, but some say it needs a clear line to the fan and occasionally misses presses.
  • NoiseCriticisedReviewers find the top speed loud, though lower speeds are more tolerable.
  • WeightPraisedAt about 6.4 lb with a handle, buyers say it is easy to move from room to window.

Lasko Weather-Shield 3720 Box Fan

  • 4.2 / 5534 ratings

Owners praise the airflow and build for the price and use it in garages, shops and windows. The main complaints are noise on the top speed and the plain, bulky design.

What people mention
  • AirflowPraisedOwners say it moves noticeably more air than smaller fans and cools a room quickly.
  • NoiseCriticisedMany find the high setting too loud for sleeping or watching TV.
  • BuildPraisedReviewers describe the frame and grille as sturdy and long-lasting.
  • Window fitMixedIt fits many standard windows, but some say the frame is too deep for their sash.

Questions and answers

Which is better for a bedroom?
The Aspen. The remote lets you change speeds without getting up, and it is lighter if you move it between rooms. The Lasko is louder on high, which matters at night.
Which is better for a window?
The Lasko. Its Weather-Shield housing is made for window mounting, and the long cord reaches outlets across a room. The Aspen is also rated for window use but has a much shorter cord.
Which moves more air?
The Aspen, rated at up to 2800 CFM. Lasko does not publish a CFM figure for the 3720, so the Aspen is the safer pick if raw airflow is your priority.
Which lasts longer?
The Lasko's aluminum housing suggests a longer service life, and owners describe it as durable. The Aspen is plastic and lighter, so treat it as the more convenient but less rugged option.
Is the Aspen worth stepping up to over the Lasko?
Yes if you want a remote, easier carrying, and more airflow. No if you need a window fan with a long cord and a sturdier frame.
Can either fan oscillate?
The Lasko listing mentions oscillation, but the 3720 is a fixed box fan in most configurations, so confirm before buying. The Aspen does not oscillate.
