Do Bathroom Exhaust Fans Really Work?
The Environment Protection Agency (EPA) states that each bathroom must have a mechanical means of extracting moisture if no window opens to provide ventilation.
So, if you want to extract moist air from inside your home, a bathroom exhaust fan is a crucial tool to achieve this. It works by a fan drawing air into the ducting located in the ceiling and pushing it to an outside vent.
There are many benefits of an exhaust fan. It stops damp penetrating the inside of your home. It prevents mold growth and mildew, as well as improving the air quality inside your bathroom.
How To Choose the Best Bathroom Exhaust Fan
So, what should you look for when you shop for a bathroom exhaust fan? Let’s consider some of the necessities.
Airflow Performance
Airflow is the single biggest consideration when shopping for that new bathroom exhaust fan. Airflow determines how potent your fan is, and is measured in cubic feet per minute (CFM).
The exhaust fan must have a minimum of 50 CFM for intermittent operation and 20 CFM for continuous use. While model codes do not cover the configuration and direction of the vent system, they do publish guidelines that require the vents to exhaust to the outside.
If you have a larger bathroom, you might need to scale up the fan size. Something closer to 100 CFM would be a better option to handle all the extra capacity.
Also, airflow determines the size of the fan relative to the room dimensions. An undersized fan will struggle in a large bathroom, impeding its performance and leaving you at the mercy of moist air.
Noise Levels
Not all bathroom exhaust fans are the same. You can buy standard fans that operate between 3.0 and 4.0 sones, which is the same volume as a conversation or radio playing at a moderate level.
Super-quiet models should be less than 1.0 sone. To give you a point of reference, 0.5 sones is the equivalent of leaves rustling.
What Fittings Do You Have?
The size of your bathroom fan not only correlates to room size, but also relates to what fittings you have in the room. If you have a shower, toilet, and a washbasin, you will likely create a lot less moisture than someone with an additional bathtub in the room.
And if you own a Jacuzzi bath, go for an oversized exhaust fan.
Location of the Bathroom Fan
Your bathroom has zones based on the moisture content in the room. A shower enclosure or bath might be the most water-laden areas of the room, so locating the fan closest to the epicenter of the dampness gives a better extraction performance.
Likewise, if you have recesses or awkward angles and corners in the bathroom, these all affect the way your fan works.
Wall or Ceiling
Where you locate your fan is crucial for the ease of installation. Wall fans are less complicated because all you need is a hole in the wall to insert the fan.
Ceiling fans vent to the exterior, either through a gable wall or the roof, which presents further complications. You need ducting and connectors, as well as a waterproof and wildlife-proof vent cover.
If you opt to vent through the roof, consider getting a professional to do the work.
Safety and Energy Performance
Make sure your chosen fan is certified by the Home Ventilation Institute (HVI) to ensure it is fit for purpose. These fans are tested for suitability and efficiency, and because the HVI is independent, you can trust the results.
Bathroom Exhaust Fan FAQs
How Many CFM Do I Need for My Bathroom Fan?
Your exhaust fan must have a minimum of 50 CFM for intermittent use and 20 CFM for continuous use. This is the bare standard set in law.
Does a Bathroom Exhaust Fan Help With Smell?
The primary purpose of a bathroom exhaust fan is to remove damp air from inside your home to the outside, but they also remove odors during that process. Odors linger in the atmosphere, so when you circulate the air in the room, it freshens the smells.
Is It Bad To Oversize a Bathroom Exhaust Fan?
It depends on what you mean by oversize. It is always a great idea to slightly scale up the CFM values to compensate for increased moisture and upgrades to bathroom fittings. If it calls for 50 CFM, choose an exhaust fan with at least 60 CFM.
However, don’t go too mad when sizing the fan. If you choose something with too much power, you risk increasing your energy costs and drawing all the heat and conditioned air from your home. It also increases the noise levels.
Which Exhaust Fan Is Better: Plastic or Metal?
Plastic exhaust fans are molded with rounded edges. They are lighter and cheaper. Metal fans are heavier and have sharp edges that could cause an injury if they fall or come off the roof.
Metal is also more susceptible to moisture damage and corrosion.
Can I Install a Bathroom Fan on the Wall?
As long as the wall is an external surface, you can install the exhaust fan in a sidewall. In some cases, it might be easier than opting to vent through a ceiling to the outside because it involves less work.
How Do I Know What Size Exhaust Fan I Need?
If you want to keep the air circulating in your space, get a fan that puts out no less than 1 cubic foot of air per minute per square foot. For an 80 square feet bathroom, you’ll want a fan with a CFM rating of 80.
Bath fans for smaller spaces are highly recommended for bathrooms with 50 square feet or less floor space. Thus, pick a fan with a CFM of less than 79 for your bathroom.
How Much Does It Cost to Have an Electrician Install a Bathroom Fan?
It depends on where you live, but having an electrician install a bathroom fan costs between $50 to $100 per hour. The price varies depending on where you live and the project’s complexity. It can take between two and four hours to install a bathroom fan.
What Kind of Pipe Do You Use to Vent a Bathroom Fan?
Experts suggest using a foam core PVC pipe for a bathroom fan. Gluing the fittings together ensures that any condensation inside the pipe will not seep out and drip through your ceiling or wall.
If you will utilize a snap-together metal duct pipe, ensure the horizontal seams are at the top of the pipe. Leaks are more likely to occur at the joints between straight pipe sections and at any angled fittings required when working with a metal pipe.
What is the Difference Between a Bathroom Exhaust Fan and a Ventilation Fan?
Exhaust fans are meant to extract odors from the bathroom and remove them, while ventilation fans will bring in fresh air.
Which Is the Best Exhaust Fan for a Bathroom?
The Panasonic FV-0510VSL1 WhisperValue is considered one of the best exhaust fans for a bathroom because it’s efficient and super quiet.
It includes a wide CFM range, so you may scale up or down the strength of the fan to adapt to varied levels of odor and moisture. It also has an adjustable speed control. This exhaust fan also features a night light capability with only 1W power and a 10W LED strip panel.
Banish Moisture and Odors
If you need to install a bathroom exhaust fan and are looking for options, this guide could be what you need. Exhaust fans are the best tools for extracting moisture and odors from the smallest room in your house.
The best fans protect against mold, mildew, and unsightly discoloration inside your bathroom.
