While a bathroom may be the least of your attention when it comes to getting your house in order, you shouldn’t neglect to find the right bathroom exhaust. This fan is intended to keep moisture out of the room and keep it smelling fresh and clean especially during warm summer days. If you’re feeling lost on how to go about, you can start with these simple ways to find you the right one for your home.
The room airflow rating will vary according to the size of the bathroom. Exhaust fans capacities are measured in cubic feet per minute (CFM) and will highly depend on the space footage.
A one CFM per square foot is recommended with a minimum of 50 CFM. Bathrooms with bigger footage (say, 100 square feet) will require higher CFM for the exhaust fan to be efficient. For the bathtub, jetted tub, toilet, and shower, just adds 50 CPM per item to get the right CFM flow. For ceilings measured eight feet and more, higher-rated exhaust fans may be needed to perform sufficient outflow of moisture.
Not all exhaust fans are the same. Sones, the noise measurement for these fans, will vary as to the space of the bathroom. One sone (or less) will have a similar noise to that of a humming refrigerator. Three sones may be louder than that of an office noise. However, most exhaust fans have sones levels of one to four.
Choose the fan that you can tolerate the noise level for about 15 minutes. This is the right amount of time to remove the moisture out of a standard bathroom. Quieter fans usually cost more so if you’re willing to pay the extra, opting for this type may be a good choice. Louder fans are usually intended for powder rooms since it has the same noise level as flushing toilets and sinks.
Common Types of Exhaust Fans
Ceiling-mounted types are usually placed in the ceiling that channels from the room to the roof or ducts. The placement is such since the dampened air usually moves up and this makes it easier for the fan to take out moisture.
Wall-mounted ones are usually installed on the walls that pull out air out of the room. These types don’t need ductwork, unlike the ceiling-mounted types.
Inline fans may be placed in the ceilings or walls with a motor that is wedged between the ducts. Air is remotely taken out of the room to the outside. Compared to the previous types, this one is relatively quieter. It is an ideal exhaust fan for bathrooms with limited spaces.
Companies selling bathroom fixtures and bathroom heater usually have exhaust fans of varying types. Some exhaust fans have lighting, heaters, and automated timers. Some special exhaust fans may also have a humidistat that takes a cue from the temperature in its environment and balances the humidity inside.
It might be best to look for fans that don’t automatically turn on and off when you switch the lights on. Chances are they are not likely to take out the moisture with the right amount of time to take out moisture.
