The rule of thumb is that you need at least 1 CFM per square foot of room area. To determine the square footage of your bathroom, multiply the length times the width. For example, if your bathroom is 6 feet wide and 9 feet long, its square footage is 54. Therefore, it should have a fan rated for at least 54 CFM.
Whatever the case may be, what is the best bathroom exhaust fan?

Next, what kind of switch do I need for a bathroom exhaust fan? If it's a typical small one speed bathroom fan you can use any on/off switch that matches the load specs; just don't use a dimmer switch intended for lights. If it's a large ceiling fan or a variable speed fan, then you need to use one of the purpose – built fan switches: both Leviton and GE make these.
Experts say bathroom fans can become overheated when clogged by lint and dust, when left on too long or because of simple failure. The heat can ignite the lint, causing the fire. ... Run the fan for only short periods, and never leave it on overnight or while no one is home.
Is more CFM better bathroom fan?
The bigger your bathroom, the higher the CFM rating you'll need. A fan should have a CFM rating high enough to replace the air in your bathroom at a rate of eight times per hour.

Bathroom fans are the most efficient ventilation units that keep your bathroom fresh and free from bad odors, smells, and common bathroom scents. For them to be effective, bathroom fans need to be installed well with the help of professional technicians to avoid any errors.
Bathroom fan installation requires outside ventilation. If the fan isn't accessible through an attic, you'll need to vent through a sidewall of your house. ... Letting the fan exhaust into an open attic will cause moisture buildup on the underside of the roof. Avoid venting through a soffit vent or ridge vent.
The dirt and dust accumulate over time and can cause the vent to make loud or vibrating noises. Other times it may be that the fan or blower wheel that spins and expels the air out of the bathroom is out of adjustment and hitting the side of the exhaust housing and thus causing the loud sound.
The fan exhaust must vent directly to the exterior of the home. Do not put the vent termination in a roof overhang or soffit. Don't put it on a wall near or under a roof overhang. The moist air that's belched out by the fan can be sucked right up into the open soffit vents and be drawn into your attic.
Bathroom exhaust fans with built-in light fixtures are fairly common. If you have one of these, you may have wired the fan and light to separate switches. Now, you'd like to operate both of them from the same switch. The wires are already where you need them to be, so you don't have to run new ones.
"You should turn the fan on each time you run water in the bathroom and leave it running for about 20 minutes after you open the [bathroom] door," says Bayne. The most important time to do this is after you shower. If you're continually forgetting to turn it off, install a fan timer.
Fans and Features Basic fan-only ventilation units can use as little as about 6 watts, for highly efficient models, while many standard units often use around 60 watts or more. In general, electricity usage is related to airflow, measured in cubic feet per minute (cfm) and the fan's energy-efficiency.
There's a small possibility with any electrical appliance that it can get too hot and catch fire, which is especially dangerous when you're asleep as not only will you have a delayed reaction time, but you're more susceptible to smoke inhalation whilst already unconscious.
As you shop for a fan, you'll probably want to consider noise level and choose a quieter model. Bath fan sound is rated in sones. ... If you're looking for a quiet bathroom fan, choose a model with a sone rating of two and under. Fans rated at three and four sones generate more white noise.
