Purpose Of Bathroom Exhaust Fan

A musty odor in the bathroom is a must unless there is an exhaust fan installed there. Whenever you take a hot shower, your bathroom will be filled with moisture. As a result, there will be foggy mirrors and you can’t see clearly in the bathroom.

If the above scenario goes on for some time, mold and mildew will grow. Besides, the moisture will damage the paint, wall, and fixtures. Overall, it will damage the indoor air quality and have a negative impact on the living quality of all your family members.

In this article, you will learn everything about why your bathroom needs an exhaust fan and if you won’t learn all about great ventilation fans, you can learn how to pick the right one.

Improved Indoor Air

The main function of a ventilation fan is to extract the excess moisture and musty odor from the bathroom through its duct. Unless you extract the moisture, they will escape the bathroom and enter into the other rooms and can make the overall air quality toxic.

An exhaust fan does not let that happen. Even before the musty odor and moisture start to spread, it extracts them outside completely. That way the indoor air quality of the bathroom improves significantly.

Since no excess moisture can’t build up inside the bathroom, mold and mildew can’t grow either. Which in turn prevents the respiratory health hazard. So, ensuring the improved air quality is the main purpose of an exhaust fan.

Improved Living Standard

Modern ventilator fans come with many other modern features like heater, humidity sensor, and night light. It’s good to have the night light when you need to go to the bathroom at night, right?

Besides, in the winter season, the heater will be a blessing for you. It will keep your bathroom warm enough to give you a comfortable shower experience. All that cool features won’t cost you much electricity bill per month.

Keeping The Bathroom Tip Top

Constant moisture in the bathroom is a natural consequence if there is no exhaust fan. These moistures will dampen the wall and the paint. Over a period of time, it will damage the integrity of the bathroom wall.

The fate is true for other bathroom fixtures the vanity cabinet, sink, shower, tub, etc. And exhaust fan will ensure the long term usability of these fixtures.

Picking The Right Exhaust Fan

There are so many popular brands in the market like Panasonic, Broan and so on. You can install it from any of them. However, you need to pay attention to some features like ‘sones’ level, CFM rating, and so on.

‘Sones’ level indicates the noise level of the fan. You definitely want to have an exhaust fan that creates the lowest level of noise while running. Sones level below 1.0 is almost noise free. However, they tend to be expensive as well.

The next thing you should pay attention is the CFM rating. It measures the air flow capacity of the fan. The more CFM rating means it can blow out more moisture from your bathroom. Ideally, 1 CFM is good for per 1 square foot of the space. So, if your bathroom has 80 square feet space, get at least 80 CFM fan.

I am not talking about how to install it, rather where to install it. But before that, you need to identify what causes the most moisture inside your bathroom. Definitely, the shower, right?

So, to take the most benefit of having an exhaust fan, you should install it as near the shower as possible. That way, it can extract the moisture from the hot shower before it can spread everywhere inside the bathroom.
