Just like any other type of fan, the tower style fans are inclined to build up a lot of dirt and dust particles inside. Because of this, your fan can benefit from a clean or service at 12-18 month intervals to ensure it continues to provide safe and reliable operational performance.
Any tower fan can use a clean when it is easy to notice dust building up in the area of the plastic venting. A regular clean is more important in homes that have family members with allergies that are made worse by dust build-up. Instead of clean air circulating through the fan the build up of dirt and dust particles will be blown through the home. Plus, any dirt left inside the fan will make the motor work harder, which can lead to more noise while in operation and also shorten the potential lifespan of this home appliance.
