Bathroom Fans Exhaust Moisture From the Shower

Properly ventilating the bathroom will reduce instances of mold and rust in your bathroom, and keep the air free of steam.

The higher the bath fan CFM, the better your fan will ventilate moisture and steam from your bathroom, preventing mold and rust

There is a set formula for calculating a minimum CFM rating for a bathroom fan. Calculate the cubic feet of your bathroom. Multiply length by width by ceiling height. We'll use an example of an 8' x 10' bathroom with a 8' ceiling. 8 x 10 x 8 = 640. Divide that number by 60 (the number of minutes in an hour). 640/60 = 10.7 x 8 = 86. So, 86 CFM is what's recommended as a minimum CFM your fan must move to properly ventilate your bathroom.

A sone is a measurement of perceived loudness. One sone is equal to about a refrigerator running in a quite room. Four sones are equivalent to a normal TV in a home at standard volume.

You never want to exhaust steam and other air into a closed space. Not only will this cause serious mold issues, which can be potentially dangerous, but you can also weaken the structural support of beams and walls

Most exhaust fans are designed to be in the bathroom but outside of the shower itself. One exception is the Broan QTRE110FLT, which needs to be connected with a GFCI circuit to make it shower safe.

Humidity-sensing fans are designed to work only when needed, saving you money. The sensing mechanism of the fan kicks on when it senses steam or humidity in the bathroom, beginning ventilation, and turns off when the humidity is gone.

They work great. A bath fan with a heater is controlled by a switch and often reaches max heating temperature within a minute—much faster than a central heater could warm your bathroom

Exhaust fans are designed to vent steam and heated air form a shower, bath, or faucet. Using one in a kitchen can be dangerous. A range hood is designed to trap grease and food particles before venting. Trying to get a bath exhaust fan to do this poses a serious fire risk.

An electrician can wire your exhaust fan so a single switch turns your light and fan on at the same time. For individual control over both (especially if you have a heater), you'll want to install a multi switch so you can control each piece individually.

Absolutely. A bathroom exhaust fan with a light is a great way to save space in your bathroom. Most bath fans with a light can have the light and fan controlled separately with a multi switch, or together using a single switch.

There are many decorative bath fans available that fit all kids of bathroom styles, from traditional to contemporary. These fans have the same great venting power, but look great in your bathroom!
