Buying guide:

The exhaust fan is often the last thing on people’s minds when building a new home or remodeling an old bathroom. It doesn’t seem like it would be all that important, but they’re actually really helpful for clearing out any smells and stale air from your space!

Bathroom exhaust fans are often overlooked when you’re building a new home or remodeling an old bathroom. They are not exciting, but they do serve some important functions in your house like removing air pollutants and humidity from the room to keep it clean for everyone living there.

Bathroom exhaust fans can be very useful, especially if you have asthma or allergies since these types of illnesses thrive on moist environments with high levels of dust mites and mold spores.

Things To Consider When Choosing The Right Bathroom Exhaust Fan

Bathroom Vent Fan Sizing

Bathroom exhaust fans are crucial for creating a clean and healthy indoor environment. The size of your bathroom is the first thing you should consider when choosing one, as this will impact how powerful it needs to be. Smaller bathrooms typically need an exhaust fan with less CFM rating due to their smaller sizes, but if yours has more than 200 square feet then its rate should match the room’s sq ft accordingly.

The CFM rating is an indicator of the exhaust fan’s ability to move moist air. It’s easy enough to calculate a bathroom size by measuring its total area, and then finding out what kind of exhaust fan would be best for that space based on the CFM rating according to HVI (the Home Ventilating Institute). A small room 50 square feet or less needs at least a 50 CFM rated unit.

Where To Install A Bathroom Vent Fan

Bathroom exhaust fans will perform best when installed near or over the main source of moisture in your bathroom. If you have a mid-sized open bathoom, then positioning it between the sink and toilet is ideal for maximum use as well as efficiency.

If you have a smaller bathroom, the best place to put an exhaust fan is at its center. If there’s not enough space for one in this area or if your ceiling is unusually high, install another vent somewhere else and make sure it has fresh air coming into it from as many directions as possible!

Extra Features

Bathroom exhaust fans used to be just that. But now, these mechanical ventilation machines often have extra features such as heaters and humidity sensors; some even come with lighting and motion detectors!

The cost of these vent fans is certainly worth it if you have to deal with the smell coming from your bathroom.

Noise Level

The sound of a bath exhaust fan is measured in sons, and the sound level of a normal conversation is at 4 or 5. The hum of an average refrigerator produces approximately 1.0 son while that same volume on television from 3 to 6 depending how close you are to it!

Low-sones bathroom exhaust fans are a great investment for those who want to avoid the noise of their fan while relaxing in the tub.

Safety and Energy Efficiency

If you’re looking for a bathroom exhaust fan that provides efficiency and safety, look no further than the Home Ventilation Institute’s (HVI) certified models. These fans have been tested by this independent organization to ensure they are safe and efficient in their function as well.

“If you want to choose an energy-saving vent fan,” “then buy an Energy Star model.” These bathroom exhaust fans are more efficient and thereby lower your energy consumption while saving money in electricity costs.
