Even the best fans will produce some sort of noise, even if it’s incredibly low. And each fan model produces a different noise level. So, you’re in the right place if you’re wondering how loud is a box fan.
Noise levels will change with different types of fans. For example, the finest exhaust fans for the kitchen will have a far different noise level than a simple 3-speed box fan. For box fans, you’re typically looking at a pretty low noise level. You can compare their noise level to that of a white noise fan or even one that produces brown noise.
Box fans can act as white noise machines if you’re looking for some background noise.
Though older generation models were quite loud, you’ll generally find that modern box fans fall somewhere between 55 to 65 decibels, which is reasonably low. If you’re looking for a new fan, try our Vornado 610DC review.
Of course, different speed settings will result in varying noise levels. Knowing how many CFM a box fan is will help you better understand this concept. Generally speaking, the higher the setting, the noisier the fan. The faster the fan blades are spinning, the louder the sound. For most models, the lowest setting will provide barely any noise.
Letting your box fan become dirty is a sure-fire way to make it noisier than you would like.
The best way to avoid your fan producing a loud noise is to keep it clean. Knowing how to clean a fan with a plastic bag will help you provide this necessary regular maintenance. There are plenty of other ways to clean your fan, however.
