Between the shower, sink, and toilet, your bathroom is probably the biggest source of moisture in your home. Unfortunately, all of that moisture accumulation leads to the growth of mold and mildew, which are dangerous to breathe and can damage the structural integrity of your home. It’s important that your bathroom be well-ventilated to keep moisture at a minimum. Here are a few tips for bathroom ventilation.
- Choose the right ventilation fan. The best bathroom ventilation solution is a fan that sucks the moisture from the air and exhausts it elsewhere. Fans are measured in the number of cubic feet per minute (CFM) they can ventilate. For a normal-sized bathroom, it’s recommended that your fan’s CFM be equal to the square footage of the room. For a larger bathroom (over 100 square feet), you may need multiple fans for different bathroom fixtures — e.g., a separate bathtub and shower. Talk to an HVAC contractor to determine what kind of ventilation you need.
- Choose where you’re venting. Where is your ventilation fan sending moisture? Is it going to the attic? To the space between two floors? That will only encourage more mold and mildew, in the worst possible places. Make sure your fan is connected to a duct that can exhaust that moisture outside.
- Consider noise levels. How loud will your fan be? To find out, look at the fan’s sone rating before installation. The quietest fans are between 0.5 and 1.2 sones. Anything up to 2 sones is quite good, noise-wise. If the rating is 4 or higher, expect a lot of noise — or consider another quieter model.
- Choose your options. Some fans have to be turned on manually, so if you forget, it’s like you had no fan at all. Now, however, there are fans with motion sensors to turn on automatically when you enter the room. Or you can get humidity sensors, which activate when there’s extra moisture in the air.
