Why Buy Dual Window Fans

Ideal for small spaces –If you live in a small apartment or small house, you won’t gain much from a room fan since all it does it is to circulate air in your home. In your case, you need a fan that take in cold air from outside while exhaling warm air and this is where window fans are most helpful, especially the reversible air flow type.

Cheaper than room fans – Most twin window fans [easyazon_link keywords=”window fans” locale=”US” tag=”gadgetrev01-20″]are priced below $50[/easyazon_link] which makes them affordable than room fans. (See the budget twin window fan here) Their maintenance costs are also lower than room fans since they consume less energy.

Ideal for irregular shaped rooms –Not every house has standard shaped square or rectangular rooms, and if you are in one of these houses, you know how difficult it is to position a room fan. Window fans can be added to the windows when needed to complement the air flow in these kinds of rooms.

Can exhaust or take in air at once –Most window fans like the [easyazon_link identifier=”B000065DKJ” locale=”US” tag=”gadgetrev01-20″]Bionaire BW2300[/easyazon_link] are designed such that each fan can work independently. You can, therefore, set one fan to exhaust warm and stale air while the other brings in cool air. This ensures that your apartment remains cool and fresh.

How To Use A Window Fan The Right Way

You should purchase a window fan that can reverse air flow in order to expel warm and stale air out while taking in cold air. Most of the twin window fans reviewed here have this capability and we highly encourage you to take advantage of that.

You should also make sure to place your window fan in a prime position where there are no obstructions outside. Make sure that you don’t place it near garbage bins since the whole house might end up with a bad odor. It is also advisable to place an exhausting fan on the sunny side and the intake fan on a cool shady area of the house.

Don’t leave your window fan on the windows when it is raining heavily and water is likely to enter the unit. Although most window fans are advertised as resistant to water, you don’t want to expose it to a risk that could easily damage the motors.

Window Fan Buying Guide

The following are some of the things you should consider when purchasing a window fan:

Size of the blade: When shopping for a twin window fan, go for the biggest blades you can find. Most of the fans usually have 9-inch blades and these work better than the 7-inch blades.

Noise Level– You don’t want a fan that will be more of a nuisance than a convenient gadget. This is why the noise level generated by the twin window fan should be taken into consideration when shopping. In our reviews, we have considered the noise levels when reviewing the fans.

Cost –Windows fans are an inexpensive means of cooling your home and it is easy to find those that cost less than $50. Although you might have to sacrifice some functionality for the low cost models, sometimes it is worth it.

Type of Windows –Twin window fans are designed mostly for slider and double hung windows. If you have any other type of windows in your home, you will find it difficult to install this fan. However, this can be overcome by getting the Avalon Twin Window Fan which has its own stands.

Thermostat –Window fans with thermostats allow you to maintain a constant temperature in your home. You don’t have to move up and down reversing the fans each time since they will automatically go off when your room reaches the perfect temperature.

Convenience –Does the fan have a remote control? If you are in a large house, you will definitely benefit from a remote control double window fan than if you are in a small house. Other features that improve convenience include functional automated settings for temperature.

Quality: The quality of a fan isn’t just about the material used to make the outer cover. Although this should be strong, the most essential feature of the fan is the motor. Make sure that the fan you select has powerful motors on both twin windows for the best effect.

Pros & Cons

Twin window fans do a great job in small and irregularly shaped apartments than a room fan would. These fans are also cheaper than room fans and consume less energy. They are easy to set up and perfect for apartment units where the air flow is tricky.

Despite the benefits of window fans, most manufacturers design their fans poorly and add inferior components that make them last shorter than room fans. These fans are also designed to work on only specific types of windows.
