Humidity sensor bath fans are an excellent way to extract moisture automatically, particularly in homes with forgetful residents. When the humidity in your bathroom hits a certain amount, a bathroom exhaust fan with a humidity sensor will automatically turn on. The vent fan will continue to work until the moisture level falls below a certain threshold. It works the same way your home’s thermostat does, except it uses relative humidity instead of temperature.

The humidity sensor is an electrical instrument that detects moisture in the air and reacts accordingly. It is used in conjunction with a simple thermometer to provide a precise relative humidity reading. Some bathroom fans allow you to control the relative humidity percentage at which the fan turns on, which is usually between 25% and 75 percent. These fans are ideal if you don’t want to bother about remembering to turn it on or have family members or landlords that you suspect are not aware of the importance of turning on the exhaust fan after showering.

Many people are unaware of how excessive moisture can cause harm to a bathroom and poor air quality. Additionally, using a fan with a humidity sensor will help avoid a fire threat. When occupants have a bath fan on all the time, the fan becomes more vulnerable to heat buildup and may catch fire at any time. There are a few things to consider when looking for the right bathroom exhaust fan with a humidity sensor.

List of Best Humidity Sensor Bath Fans

You picks for the best bathroom exhaust fans with humidity sensors are listed below. Depending on the amount of moisture in the shower, these humidity-sensing fans will switch on and off. Go reading to see the rest of my reviews.

1. Panasonic FV-0511VQC1 WhisperSense DC Ventilation Fan

You’ll have a hard time hearing this Panasonic because it’s so dark. However, it works at a decibel level of 0.3, which is quieter than rustling leaves.  It comes with a Pick-a-Flow speed slider that lets you switch from 50, 80, or 110 CFM, depending on the situation. It also includes a Flex-Z simple bracket for attaching four or 6-inch ducting.

2. AC Infinity AIRLIFT T10, Shutter Exhaust Fan 10" with Temperature Humidity Controller

The exhaust fan’s optimal position is often in the wall. If you don’t have access to a ceiling fan because you live in an apartment, a wall-mounted fan will suffice. This AC Infinity model is compelling, and it comes equipped with an intelligent programming feature that allows you to control the humidity levels.

You’ll also get correct moisture and temperature readings, as well as a 40% electricity cost reduction. You can also adjust the rpm, set a timer, and set the alarm. Since the dual-ball bearings are suitable for 67,000 hours, this device can last for years.

3. Delta BreezSmart SMT130H 130 CFM Exhaust Bath Fan

This fan will make you happy if you like having control of the humidity levels. You can set the levels anywhere between -50 and +90 percent. Who, without a doubt, encompasses all eventualities. The fan runs at 130 CFM when the moisture levels reach the highest fixed point. When the levels decrease, the fan slows down to a 50, 70, or 90 CFM speed.

It produces 0.3 sones, which puts it on par with the Panasonic in terms of volume, and it uses less than 17 watts of power thanks to its Energy Star rating. In addition, this model allows you to adjust the humidity levels over a wide range of temperatures, from -50 to +90 degrees. That covers all types of bathroom use and climates.

4. Homewerks 7146-80-MS Bathroom Fan Integrated Dimmable

This exhaust fan has a humidity monitor and a calming LED light that can be dimmed to help set the mood in the bathroom. It’s a single-speed fan, meaning it only moves 80 CFM but is very silent at 1.5 decibels. It would help if you switched the humidity sensor to auto-on, which means it will turn on when the fan senses dampness in the air and turn off when the humidity level falls below 60%. The light is also motion-activated, so it turns on automatically as you step into the room. If you have children, this is a huge plus.

You also get an LED wall switch that gives you complete control over the features, including the ability to turn off the auto-humidity sensor if desired. Using the motion sensor light instead of turning on the bathroom light is a super convenient way to light the room. This feature would appeal to both children and elderly relatives.

Buying guide

Sensor Humidity Adjustments:

It is one of the most important and perfect factors to remember for these fans. You can’t choose the humidity setting on all exhaust fans. Adjustable fans usually have a knob inside the fan housing to set the relative humidity to somewhere between 25% and 75%.

Fan Speed (Fixed or Adjustable):

You can also monitor the fan speed measured by CFM for sure ventilation fans. The Panasonic WhisperSense has a switch on the inside that allows you to pick either 50, 80, or 100 CFM. The majority of bath fans will have a high and low-speed setting. For instance, in high-speed mode, you might want the fan to run at 80 CFM, while in low-speed mode, you might want it to run at 6 CFM.

Since certain fans have set speeds, make sure to review the product specifications to see if this is a choice for you.

Bathroom Dimensions:

The size of your bathroom is crucial since it will decide how powerful of a fan you buy.

Suppose you buy a bathroom fan that is too strong. In that case, you can waste energy and cause negative air pressure in the household, potentially affecting other home appliances like the refrigerator, fireplace, and water heater. If you buy a poor fan, it will not vent enough air, resulting in bathroom moisture damage and mold formation.

Choosing Fan Power:

This statistic essentially indicates how much air the fan will remove in one minute. As a general rule, measure your bathroom floor and add 1 CFM per 1 square foot of floor space when sizing your fan. E.g., if your bathroom floor is 80 square feet, you’ll need a bathroom fan with at least 80 CFM. If your bathroom is more significant than 100 square feet, you can start applying CFMs depending on how many fixtures you have.

Housing Dimensions:

The housing size refers to the exhaust fan’s metal or plastic container, not the removable cover or grill, which is usually bigger. The housing is the part of the fan that would screw to the joists of your ceiling.

It’s a brilliant idea to measure the size of your current home before making a purchase. If the fan is too small to fit between the joists, you should still apply wood blocking. However, if the fan is too big, you’ll have to break the beams, which is usually a terrible idea. It’s also a perfect way to double-check that the ceiling cavity has sufficiently vertical space.

Levels of Noise:

A ventilation fan’s noise level is estimated in sones, a basic unit of measurement for loudness. A bathroom fan with a noise level of 1.5 sones or less is considered silent, and something with a noise level of less than one sone is considered exceptionally quiet. The underlying principle is that doubling the sones doubles the noise frequency.

Some residents may choose a marginally quieter fan because it creates “white noise” and provides some privacy. Others can need a whisper-quiet fan for several reasons, such as not disturbing a sleeping infant.

Final Thoughts:

Humidity-sensing exhaust fans are the most convenient and hassle-free way to remove moisture. You don’t have to wonder about it or be concerned that you’ve got the fan running all day because it’s ideal for little children. It’s as if you have an all-seeing eye looking over your toilet, turning on and off the fan as appropriate, so you don’t have to.
