2020 Review of the 9 Best Window Exhaust Fans

The best window exhaust fans offer a convenient and affordable way to keep your space ventilated with plenty of fresh air. Most homes could use the numerous benefits of an odor free home and a much cooler space.

Further, window fans also provides an excellent opportunity of saving a significant amount of money during the hot season. This is because running a window fan instead of the air conditioning all summer long uses up minimal energy and therefore less cost.

Unlike a central cooling system that cools the entire home including rooms not being used during the day, a window fan will cool smaller and isolated spaces that need cooling such as the living room, bathroom or bedroom.

Also, they use little energy yet enhance comfort on a hot day.

Whether you have a central cooling system or not, a window exhaust fan can play a key role in keeping your home fresh, cool and well ventilated.

Buyers Guide

Consider these things when choosing a window exhaust fan;

  1. Size of your space

You will want to consider the size of your space in order to get the appropriate window fan that has enough power to adequately serve that space.

To determine the size of the fan needed for your room, the Home Ventilating Institute prescribes the following formula. Note the area of the room and multiply it by 1.1. Bear in mind that this calculus is under the assumption that you have an 8 foot ceiling. So if you have, a 20 ft by 30 ft room, then you will require a fan with a rating of 660 CFM .That number has been arrived at by multiplying 20’ x 30’ x 1.1 = 660.

It is important to note that this is only a minimum recommended size for this space so it is not cast on stone. In fact, it is not a bad idea to spend some few extra dollars for a more powerful model. It may even be a better idea because the cost of installation for bigger models will be just about the same as that of a smaller model.

  1. Construction

Most window exhaust fan exteriors will be constructed from tough and hardened plastic while the blades will often be of ABS plastic which is malleable but firm and durable. Check to see the unit is sturdy and can withstand being exposed to rain, moisture, dust and heat.

  1. Window dimensions

Before purchasing a window fan, be sure to check the size of the unit and whether it will fit your window. The specification will indicate the type of windows that the unit can be fitted on as well as the minimum and maximum width of window frames within which the unit can be mounted. In case you have a large window that is not within the prescribed dimension, it works better to choose a unit with expandable flaps on either side as this make it so much easier to custom fit the unit to the size of your window.

  1. Installation

In addition to the window dimensions, also look out for whether the unit has to be held in place by the window and whether the window can close without having to remove the unit. Some units can stand alone on a desk or table top in addition to having the option of installing them on a window. So look out for that option if you don’t necessarily want the unit on the window.

  1. Single fan or Dual fan

This is based on individual needs and preference. A single fan can exhaust, and intake air but not at the same time. A dual fan can accomplish these two tasks simultaneously. If you want fast efficiency it doesn’t hurt to consider the dual fan.

Now that you have a good idea on what to look for when buying an exhaust fan, let’s explore some of the best window exhaust fans in the market today.
