The bathroom should be kept free of stale and humid air. So a good ceiling fan or a ventilation fan is required to keep the bathroom airy and well ventilated. You consider the size of the room, light options and sound levels before buying a bathroom ceiling fan. Large bathrooms will need more effective ventilation as compared to a small space to filter out the humid air, dust, mildew and other odors from the bathroom. Apart from the simple ceiling fans, there are decorative fans or a fan with an inbuilt heater or a fan with humidity sensing technology. As moisture and humidity rise to the ceiling so installing a humidity sensing bath fan can be quite beneficial. You can get one that suits your requirements and install one with the help of the bath fan installation guides.
If the bathroom is not well ventilated the walls will become moist due to the steam from the shower or bath, creating a damp and mildew filled atmosphere in the bathroom that will over time spread to other rooms in the house. Major damage can occur as mold and mildew will degenerate the structure of the home. Homes often come with built -in bathroom exhaust fans which are sometimes attached with the lights. A bathroom ceiling fan is the best option in case you do not want to go in for an expensive or a high quality exhaust fan. Ventilation of the bathroom is not possible with a ceiling fan but it can definitely circulate the air, keeping the walls free from moist air. In case your there is no window in your bathroom even the ceiling fan will not be of much help to reduce moisture. On the other hand a window coupled with a ceiling fan can provide the function of an exhaust fan but without the disturbing sounds.
A bathroom is a place where the atmosphere should be one of comfort and odor free where you can relax. Proper measures should be taken to avoid moisture and mildew. Bathroom ceiling fans come in 42inches to 50 inch blades depending on the size of the bathroom. Bathroom ceiling fans are UL listed basically for damp places as they can withstand humidity and moisture. Walk-in-closets and laundry rooms should also be fitted with such ceiling fans to keep humidity at bay.
