Choosing the Best Exhaust Fans for Bathrooms
The bathroom is one of the common targets of mold and bacteria because of the excess moisture from showers, tubs, and other fixtures.
Without a fan to suck in the stale air, moisture can quickly accumulate on your bathroom surfaces, creating a perfect environment for mold and bacteria.
A properly functioning exhaust fan provides ventilation by drawing in humid air and odor from your bathroom.
Choosing the right bath fan can be complicated, given the many options.
Thus, before you start shopping around for the best exhaust fans for bathrooms, here are the factors you need to consider:
Fan Size
The first feature you need to check before buying an exhaust fan for your bath is the unit’s fan sizing, measured in cubic feet per minute (CFM).
You must select the appropriate size for your bathroom’s square footage.
Doing so ensures that you will get the right amount of ventilation in the space.
Generally, you need one CFM per square foot of area. For example, an 8″ by 10″ bathroom will require a bath fan with at least 80 CFM.
Smaller and less powerful fans are great for small bathrooms, while larger fans that generate higher CFMs will work better in larger areas.
Installation
Most bath fans are installed on a ceiling, while some models can be installed on a wall.
Whatever you prefer, opt for a device that is easy to install and requires fewer tools.
Most experts recommend installing a fan to vent air outside your home through existing ductwork, not into an attic.
That’s because venting into an attic will only transfer moist, warm air to it, where moisture problems can develop.
Choose a model with an appropriate size duct adapter. If you’re installing a fan over a shower-tub combo, ensure it’s UL-listed or certified for this location.
Noise Level
Another thing to consider when selecting a bath fan is the noise level.
Exhaust fans that sound like jet engines can offset the relaxation and peace you have in the bathroom. Thus, you want to choose a quieter model.
Bath fan sound is rated in sones. The lower the sone, the quieter the unit is.
Look for an exhaust bath fan with a rating of one or less. One sone is equivalent to the hum of a refrigerator in a quiet kitchen.
Efficiency
Efficiency should be your main priority when purchasing any home appliance.
Energy star-certified fans use 70% less electricity than conventional non-energy star models.
While they typically cost more upfront, you can save a lot of money in the long run from utility bills.
These models also meet the qualification for low wattage consumption, efficient performance, and low sound emission.
Features
Modern bath fans have several features that make them more efficient and convenient to use.
For instance, some models have integrated lighting that can replace your existing fixtures or serve as supplementary lighting.
Some bath fans include a night light that delivers soft illumination during the nighttime hours.
Other fans have built-in sensors that help conserve energy and improve the unit’s overall efficiency.
Meanwhile, other models have built-in heaters that supply extra warmth if you live in a cold climate.
Frequently Asked Questions
What is the best type of fan for a bathroom?
The centrifugal fan is able to generate more pressure, which is perfect for lengthy duct lengths. A centrifugal fan is your best option if your bathroom lacks exterior walls in order to provide adequate circulation. Furthermore, compared to other fan types, centrifugal fans frequently provide more switching and operating options.
Do I need a more powerful bathroom exhaust fan?
A small-room bathroom exhaust fan is what you should get for bathrooms that are 50 square feet or less. That is, select bathroom exhaust fan with a CFM of less than 79. Use 80 to 99 CFM bathroom exhaust fan for bathrooms that are average in size. Use a bathroom exhaust fan with more than 100 CFM for large bathrooms that are larger than 100 square feet but smaller than 150 square feet.
What is the difference between a bathroom ventilation fan and an exhaust fan?
An exhaust fan extracts air from the surrounding space, whereas a ventilation fan introduces fresh air.
