Many bathroom installations have the fan controlled by the same switch as the light, resulting in the fan being turned off as soon as the occupant leaves the room. It is recommended that a separate switch control the fan or, better yet, a timer that allows the fan to run for a pre-determined amount of time after showering.

Apr 2, Converting a Closet to a Powder Room. Jun 6, Mar 14, It can sometimes be very important to insulate the bathroom duct if it goes into an attic, garage, or crawl space. With the temperature difference between the bathroom duct air, and the uninsulated room, condensation or water beads can form on the duct.
This condensation can lead to wood damage or even mold growth. The flapper will either be a circular flap or it will be three louvers. The flapper or grille allows air to move to the outside, but when the exhaust fan has stopped, then these flaps will close to prevent exterior air and bugs from entering the duct. Birds just love to make nests in these flexible ducts because they are secure and sometimes warm places.
It's really no different than making a nest in a tree hole. When the bird makes the nest, it can completely block the air flow and making your bathroom fan useless. It can even be a fire hazard if it causes the fan motor to overheat. In fact, birds nests in dryer vents are a very common fire hazard because the heat builds up in the duct due to the dryer. To prevent bird nests, there should just be a flapper, but also some type of screen. But you don't want a screen with small holes though because these can get easily clogged with debris.
A screen with centimeter sized holes is the right size. In the big box stores, they call these screens 'pest barricades'. The CFM rating basically means how quickly the bathroom fan can exhaust the air in your bathroom on a per minute basis.
The lowest CFM bathroom fans are in the cfm range, but household bathroom fans can go as high as cfm. Anything higher than around cfm is usually reserved for commercial properties. For bathrooms with sf or less, the general rule is 1-cfm for every square foot but with a minimum of cfm. CFM Guide.
One common complaint of bathroom fans is their noise. Some bathroom fans are just noisy, and you can hear them down the hallway. Other bathroom fans are so quiet that they have indicator lights just so you know that they are on. Anything that is 1. Anything in the sone range would be average. Sone isn't a physical measurement, but it is a rating based on how humans perceive loudness. When you double the sone rating , you double the perceived loudness, so a 4-sone is twice as loud as a 2-sone fan.
You flick the switch when you are taking a shower, and then you flip it off when you are done.
