How long should the fan be running? You should turn on the fan as soon as you turn on the shower or bath water. Additionally, leave the fan on for about 20 minutes after you're finished bathing. This will help keep your bathroom free of moisture and mold.
You need to ensure you use your bathroom fan for long enough. It needs to run throughout your shower and/or bath. As such, we suggest running your fan for at least 15 minutes after you've finished showering or bathing to fully air out the bath room.
In the bathroom, the exhaust fan vents air outdoors. The primary time to use this is when you take a shower. The fan helps dry out the room so the steam of the water and the humidity and moisture it creates doesn't just sit there and dampen the walls and appliances.
In addition to mold spores, there are a range of other airborne contaminants in your bathroom that an exhaust fan can also help to reduce, including dust and debris, various bacteria and pathogens, as well as VOCs (volatile organic compounds) from cleaning chemicals.
One Foot In, One Foot Out – Ideally, you should place a bathroom fan in the ceiling about 1 foot from the shower and between the shower and the door.
A further consideration to take into account is the positioning of the fan. You will want to install them as close to the source of air moisture as possible, usually above the bath or shower, and be sure to choose a product with the correct IP rating (usually IPX4 or above is enough but always check).
Get out of the bathroom as fast as possible. The humidity of the air will not help you stay dry. Dress as little as necessary and then finish outside, in the open air or preferably in front of a cool breeze or a fan.

Be sure to leave your shower door open and bathroom door open after taking a shower to keep air moving around your shower. If you have one, be sure to leave the bathroom vent fan on until the temperature has cooled down and the steam is gone.
Directly over a shower is very wet, so that will shorten the life of the exhaust fan. A good option is to buy an exhaust fan with a humidity sensor that automatically comes on and runs automatically until the moisture is gone. This will reduce moisture, mold, and corrosion in the fan.
Leaving the exhaust fan running for an extensive period of time can cause significant wear to the motor and may cause a fire. It's a cause for concern, especially when you're not home to hear your smoke detectors!
Experts agree that you should not leave your bathroom fan on all night. You should only run the fan for about 20 minutes during and after a bath or shower. You especially shouldn't leave it on at night. If it's run too long, it can cause serious problems and become a potential fire hazard.
Sleep Advisor says that as the dry air moves around the room, it "causes flurries of dust and pollen to make their way into your sinuses". For those with asthma or allergies, it could mean those problems are made worse by using a fan.

To air out a room: If there is a foul smell inside the house or smoke in the kitchen after cooking, set your fan directions to run clockwise at a medium speed. This will draw the air up and out toward the walls. Open the doors and windows to invite fresh air into your home and eliminate the odor or smoke.
As soon as you get out of the shower, wipe the floor and close the curtain so it can fully dry out. Shower curtains are prime targets for mildew. If you have a shower with a door, leave the door open to air out the inside of the shower.
According to The Spruce, the simple act of closing your shower curtain can help speed up the drying process.
