There are many fans available on the market and you should choose one that suits your needs. A cheap fan is not necessarily a bad choice but it might be cheaper for a reason. A cheaper fan might be inferior in quality or have a shorter lifespan. Some of the features to look out for when buying a fan include: 1. The size of the blades. 2. The number of blades. 3. Whether it has an oscillation function. 4. Type of noise level, and lastly its speed.
