Most duct booster fans are not designed to run continuously, though some models can be programmed for constant operation. Typically, they are controlled by the user via a switch, controls on the unit itself, or by being wired to the HVAC system's thermostat. Wiring the fan to a thermostat allows it to run automatically only when heating or cooling is active, which saves energy and is an effective way to activate the fan only when needed to address issues like uneven room temperatures.

Your bathroom exhaust fan shouldn't be loud. However, bath fans come in a wide variety of models, price points, and loudness characteristics, and yours may be louder or quieter than others you notice. Economy models tend to be the noisiest, with levels of 4.0 sones or more, which is about the sound of an electric shaver, while some high-end models can be barely audible. 

Stainless steel or aluminum fans are long-lasting and have less air resistance. They are best for outdoor use as their durability helps them withstand unpleasant weather conditions. Their heavy weight requires a stronger motor, which leads to more noise than other blade materials.

Wooden fan blades are a classic, durable option. They are much quieter than metal fans and feature a wide range of styles and finishes to choose from. However, they can be damaged by moisture if not covered with plastic.

Plastic fan blades are lightweight, easy to clean, and versatile. There are various shapes and styles to choose from as plastic is easily molded and dyed. They will also deteriorate slower than other materials as they aren’t as susceptible to humidity and moisture.
