This large size Lasko window fan is not the Rolls Royce of fans but it is an acceptable fan which comes at an affordable price. Less noise production and good air movement are some key features of this model.
Usually you won’t be able to open and close your windows, like you would normally, after the installation of a window fan, but this unit is specially designed to fit in the windows without forcing you to keep them open. This means that you can close your windows whenever you’re not using the fan to keep the bugs out.
Another great thing about this fan is its reversible technology which lets you choose between exhaust or air flow options for your fan. This makes this product flexible enough to be used in kitchen as well as in bedrooms. Also, its speed control settings (Low, medium and high) lets you adjust its speed as per your requirements.
When we take a look on other side of the picture, this model has some noticeable flaws too. Absence of thermostat and immovable grills, to direct air towards a particular direction, are proven to be a major issue for many customers. But overall it’s a good choice for people having spacious rooms but limited financial resources.

A dual window fan, manufactured by Lasko, is a mini pack with wide range of functions. Lasko twin window fan, 2137, is a two speed fan which can operate at either low or high speed. This is designed in such a way that it can be used as a window fan as well as a table fan.
Although this model consists of two fans but they manage to keep the power of this fan to a satisfying level. Even with its small size, it’s capable of delivering powerful functionality for its users. Also, it’s extremely efficient at keeping the noise generation at minimum. When one chooses to install it as a window fan it still is flexible enough to be adjusted in different size of windows ranging from 22 to 34 inches.
There are few cons of this specific model as well. It is a one direction fan, which means that to change its function form intake to exhaust, one has to remove it, flip it and then reinstall it again. Lack of thermostat control is also a hindrance in its use for people who desire to have an automated fan which can automatically be adjusted according to temperature change. These shortcomings result in sufficient decrease in its popularity among customers but it’s still a reasonable option for customers who need a one directional powerful small fan at cheap rates.
This dual window fan surely is an impressive product when it comes to features and advantages when compared to others. Its appropriate size which can be further adjusted for windows of size 25-35 inches when combined with its thermostat control make it a distinct product of Lasko manufacturers. Two speed control settings along with the independently working fans made it a real eye catcher. With the help of reversible fan technology, living rooms or kitchens can be kept cool and smoke free. Its specially designed feet lets it adjust on flat surfaces as well.

This product of Lasko Company is excellent in both efficiency and durability. This model is equipped with many technologies such as thermostat control, airflow reverse technology and independently controlled fan system that makes it a beast in summer seasons. Thermostat control helps in adjustment of speed of the fan in accordance to temperature. Its three speed settings can be adjusted to suit the user’s requirements. Ability of fans to work independently allows the use of the same dual window fan for exhaust, intake or exchange at the same time. It is an adjustable window fan which can be adjusted according to the size of the window (ranging from 25 to 35 inches). Extra advantage of this fan is that it can be used as a table fan along with the conventional window fan use.
This Lasko twin window fan has some flaws that should be kept in mind before going for this fan unit. Fixed vents restrict the choice to direct airflow in a particular direction. Also, you cannot close the window or its grills when you’re not using the fan. This makes it really difficult to keep the bugs out especially in winter season. Its accordion extenders can be troublesome as well because of their poor design. But these flaws can easily be ignored considering the fact that it’s available at a reasonable price.
So, Which Fan Is The Best? Verdict
In this Lasko window fan review, we took a look at three different window fans: one one-motor fan and two twin ones.
Among all of these models, Lasko 2155A window fan is the first on the list thanks to its reversible fan technology. It is a large triple speed fan capable of delivering powerful airflow. As already mentioned, it is an electrically reversible fan which means it has the ability to work as an exhaust and it can easily be used for airflow as well. Surprisingly, its large size does not result in excessive noise generation.
Lack of thermostat and fixed vents are also points of concern for customers who want to use it in hot regions. Lack of snap-on feet limits the use of fan only as a window fan.
Lasko 2138 8-Inch twin window fan is at second spot. This dual window fan is a real gem for customers who want to buy an efficient fan at a very reasonable price. This is basically a two speed compact ETL (Electrical Testing Laboratories) approved fan. It has reversible fan technology, which enhance its productivity. A striking feature of this fan is that it can easily be set on flat surfaces as well, credit goes to its snap-on feet. Built-in thermostat is also a great addition in its long list of functionality which definitely increases its worth. This is an adjustable window fan, which can be fixed in 25 to 35 inches wide space thanks to its extender screen.
Few shortcomings of this electrically reversible twin window fan include inability to close windows when fan is not in use. Immovable grills are also a problem in directing air up, down or in the middle.
Lasko 2137 twin window fan is at third position. It is a two speed (high and low) small fan with reasonable price tag. This fan unit is also approved by ETL (Electrical Testing Laboratories). It has snap-on foot due to which it can easily be used as a floor fan as well. It’s an adjustable window fan which can be adjusted in 22 to 34 inches wide windows because of extender screen.
It is a one directional fan which is a major drawback of this fan. Other cons of this product include lack of thermostat and dependent fans.
So we have listed all the features of three Lasko window fans and compared them in terms of their functionality. Although all of them are amazing at what they are designed for, but Lasko 2138 8-Inch Electrically Reversible Twin Window Fan is the one that offers the most features when compared to others.
