5 Best Window Fan for Multi Use – Efficient Ways To Circulate Air

Window fans are excellent candidates for cooling entire rooms and even homes but only at a fraction of a cost of an air conditioner. At the same time, they can also help bring fresh air from the outside indoors and remove stale air from the indoors sending it outside.

Plus, you get the added bonus of the exhaust system that filters out unpleasant odors and such making indoor air quality more agreeable. But, because there is a huge variety of window fans available in the market, it can make choosing one for your home or office slightly challenging.

There are different sizes to choose from since windows can also vary greatly in dimensions. There are construction materials to consider that will affect the performance and longevity of the fan and then there are functions such as intake, exhaust or exchange that you will have to think about as well.

So, here are some of our recommendations that can help you narrow down your choices.

The 5 Best Window Fans

1. Air King 20″ Whole House Window Fan

AC Infinity AIRPLATE S7 150x150

The Air King 9166F is a window fan that is available in a variety of sizes. However, for our review today, we will look at the 20-inch version of this model.

This fan ideally fits windows that have a span of between 27 and 38 inches across and are 26.25 inches high. Powered by a 1/6 HP motor, the fan yields an RPM of 1600, 1450 and 1100 at its 3 speeds of High, Med and Low respectively.

The 3 speed settings give users a fair bit of leeway in choosing the degree of air circulation they want. While the first two settings are relatively quiet, the High Setting may become somewhat noisy when placed in close proximity to the bedroom.

The model lets you close the window behind it which is a feature missing in many other window fans. You can use this feature to secure your home without having to remove the fan.

The construction is industrial-grade plastic with plastic housing that is tress resistant and a front and blades that are power-coated.

This AC Infinity product comes from a line of similar products best suited for installation in component shelves and cabinets that need cooling at minimal noise levels.

One single airplate is 11.69 inches wide and 6.1 inches tall featuring twin fans. You can, however, daisy chain multiple units together to share the same speed controller and wall outlet. Manufacturers say that it’s safe to let six units share the same USB or wall outlet power source.
