Features to Consider for the Best Humidity Sensing Bathroom Fan
With each of these fans, there are ways to adjust just how much you want your fan to respond to moisture in the air to prevent mold, mildew, and other unwanted symptoms of high humidity. In some cases, you will want humidity to be virtually non-existent. In others, having a bit of steam in the room is fine. However, if you have slick ceramic tile or rugs that seem to hold in water, a setting that only allows 10% humidity might be the best choice for you.
Check to see if your fan is Energy Star qualified to guarantee efficiency in your electrical power usage. While it is important to have a fan that works strong and fast, it might not be the best choice if you are worried about a power surge or a spike in your electric bill. Luckily, each of the fans we included in our review are Energy Star approved and would not cause a major increase in your utility bill.
Some people like to have a fan on to cover up bathroom sounds such as using the toilet or singing in the shower. If that is a concern for you, then the best humidity sensing bathroom fan probably is not the quietest product on the market. Most of these fans boast their silent features and their ability to do a great job with low noise. If you are wanting to have a tangible way of measuring the sound your fan will project, look at the sone unit. Sones are a measurement of sound. The lower the sone count, the more quiet and comfortable the environment will be. The higher the sone count, the louder the noise will be. This measurement is not like decibels or volume, but more on how the sound is sensed.
How much you pay is a concern regardless of the purchase you are making. Some fans can be well over $100 and others can be in the $60 range. Whatever your budget, make sure the fan you buy is the fan that you need. If you do not need a new fan, maybe a switch that could sense the humidity is a good choice and could save you a few dollars. But if you can afford a fan with all the fancy features and it will fit in your home, more power to you.
Let’s be honest: some fans are just not aesthetically pleasing. On the flipside, the fans that are beautiful may not be the most powerful or useful fans out there. If finding a fan to fit your bathroom’s theme is a concern, look for a sleek fan without a distracting grille. If a fan with a grille is more your style, there are plenty to choose from. If you are looking for something other than white, there are limited options, but some could potentially be painted. Seek your user manual before going that route.
Benefits of Using Humidity Sensing Bathroom Fans
In many cases, your bathroom is the most humid and condensation-producing room in your home. From hot showers to flushing toilets, water is everywhere and likely in the places you cannot even see. For this reason, mold can be a huge problem in bathrooms. It can grow at the bottom of wet shower curtains and in soggy ceiling tiles. With the best humidity sensing bathroom fan, air circulates throughout the room, which helps to prevent mold from wreaking havoc on your bathroom. Mold is not only unsightly and smelly, it can also be dangerous, so having a bathroom fan to eliminate excess moisture levels is important.
Because these fans actually sense when the room is humid, they are extremely energy efficient. Many of these bathroom fans actually shut off on their own once the room reaches its desired humidity level. No more worrying about forgetting to shut off the fan.
Precautions of Using Humidity Sensing Bathroom Fans
Make sure you are adjusting the fan blower based on your desired humidity level. If you are not sure what this means, experiment with different levels of humidity and see what works best with your bathroom. Be aware, too, some of these fans do not offer self-adjustment for humidity. If this is a concern, look for a fan that allows you to adjust based on your own preferences and what works best for your bathroom.
Now obviously when you order these fans online, they do not arrive with a person who will install it for you. Luckily, the internet has some great reviews and comments about how previous customers installed their own fan. With any self-installed product, understand there are risks of user-error for how these products may have been improperly installed.
If there is a concern for your own abilities to install this fan yourself, educate yourself as much as possible on how to properly install your new bathroom fan by reading reviews, asking questions online and watching how-to videos. You can also take it a step further by reaching out to a professional for additional guidance and assistance.
After much deliberation, we chose the Delta Breez 80 CFM Exhaust Fan with Adjustable Humidity Sensor as the best humidity sensing bathroom fan for our needs. It is at a comfortable price point, and has all the features we need to do the job.
We hope this gives you some more information and helps you to find the best humidity sensing bathroom fan for your home.
