The Benefits of Having a Window Fan

Taking out the warm air through the Exhaust will make your room cooler instantly. Having the Intake feature with definitely speed up the cooling process. This is the reason why most people use window fans together with their air conditioners.
2. Window fans can promote better air circulation

You can easily get rid of pollen, dander and smoke with a window fan. The air exchange feature of a window fan will surely get this job done effortlessly by letting fresh air in and dirty air out.
3. Window fans eliminate odors

How to Choose a Best Window Fan?
1. The size and type of your window
The most important thing to consider before buying a window fan is whether it will fit your window. Aside from the size of your window, you also need to check the currently installed accessories that might get it the way of the installation. These window fans fit most double hung and slider windows, but if you have installed screens and grills, you have to consider those too. The last thing you want to happen is making alterations to accommodate one.
2. The room you’re putting it in
All of these brands may claim that the velocity of their fans can make medium to large rooms cooler in minutes. But since not all room sizes are the same, you may want to try getting one for a medium-sized room first as a trial for the rest of the rooms in the house that might have a similar size. For larger areas like your kitchen, living room and entertainment area, consider getting a bigger one or the one suitable for offices. These are bigger in size but have a more quiet motor than industrial ones.
3. Type of motor
Always research the durability of the window fan’s motor. Some are made water-resistant and some are not. Some fans come with a rain guard and that is an indicator that the motor is not suitable to be exposed during the rainy season. For these types of window fans make sure that you can still close the window behind it. Otherwise, choosing a water-resistant is a smarter move.
4. Safety Features
Having a water-resistant motor is a safety feature. Likewise, there are window fans with built-in safety fuse on the plugs to prevent electrical surge that may damage the unit. Another simple but effective safety feature is an insect screen, it does not just keep your fan clean but it keeps pests away from the blades and the motor.
5. Convenience Features
It’s not enough to just get a window fan that can make your room cooler. It must have other convenient features that will make it work efficiently and work for you conveniently like having a programmable thermostat, simultaneous air exchange and remote control among others.
