8 Best Humidifier with Humidistat Reviews 2020

Whenever you’re buying a new humidifier, it is advisable to consider one with a humidistat. Although you can purchase a hygrometer (also used to measure humidity levels) separately, most HVAC experts recommend a humidistat because it provides additional control features, whereas a hygrometer only measures humidity. 

This guide explores why you should consider a humidifier with an onboard/built-in humidistat, how these humidifiers work, how to use/set the humidistat, and how to maintain a humidifier with a humidistat. First, though, let’s take a look at the top eight humidifiers with built-in humidistat function.

Best Humidifier With Humidistat Buying Guide

With the reviews covered, let’s now get down to how to buy the right humidifier with a humidistat. The whole process begins with you understanding what a humidistat is and how it works.

What is Humidistat?

A humidistat, sometimes called a hygrostat, is a small measurement instrument that homeowners can use to monitor and maintain the desired relative humidity of air in a given space. 

In Home-Heating, ventilation, and Air Conditioning (HVAC), a humidistat is often used alongside a humidifier to set and maintain preferred humidity levels indoors. Indeed, most humidifiers come with a humidistat – either built into the humidification unit or included in the package as a separate device. Whichever is the case, such humidifiers are wired or wirelessly connected to the humidifier and can be used to command the humidifier. 

This, however, doesn’t mean that there are no stand-alone humidistat units. On the contrary, there are many small humidistat units sold independently. These units don’t come as part of a humidifier or any HVAC package. It’s important to understand that most stand-alone humidistat units operate as hygrometers. 

Humidistat vs. Hygrometer; Is There a Difference?

humidistat vs hygrometerYes, there is. Although both instruments measure the relative humidity (quantity of moisture in indoor air as compared to outdoor air), the two devices are also slightly different. 

A hygrometer is designed for measuring the level of moisture in the air – full stop. It doesn’t do anything beyond that. A humidistat, however, goes way beyond measurement.  With a humidistat, you can also manipulate the humidifier. For example, you can set the desired humidity level and even change the settings as you wish, and the humidifier would adjust its operations accordingly to attain and maintain the set humidity levels. 

How Does a Humidistat Work?

A typical household humidistat comprises a relay amplifier and sensing element made of a material that is sensitive to moisture. In most humidistat units, the sensing material is made from human hair or silk. Both of these materials are able to absorb and expel water multiple times without significant damage. 

If the level of moisture in the home increases or falls, the sensing material (after absorbing or losing moisture), tightens or becomes loose, thus strengthening or loosening the electrical resistance between the two attached metal conductors. The relay amplifier tracks these changes. 

The relay amplifier, in turn, is wired to the humidifier and thus communicates current moisture levels, causing the humidifier to slow down or amp-up operation as needed.   

Advantages of Humidifiers with Humidistat Function

There are three main reasons you should consider a humidifier with humidistat function. These are;

  • Ideal comfort: The reason we invest in home heating, ventilation, and air conditioning in the first place is to achieve ideal indoor comfort. Unfortunately, without a means to control how much moisture the humidifier releases into your room, you may end up with too little or too much indoor moisture. A humidistat allows you to maintain perfect indoor moisture round the clock.
  • Health reasons: Too little or too much moisture in the air can cause various health issues for you and your family. Too much humidity creates a breeding ground for mold and mildew, both of which are triggers for allergic reactions. Overly dry conditions, meanwhile, can cause dry nasal passages, resulting in nosebleeds and cold symptoms. A humidistat allows you to maintain the right humidity levels so you can avoid these issues.
  • Furniture health: Finally, a humidistat is also vital for the health of your furniture and other valued items. The mold and mildew often experienced under overly moist conditions, for instance, can damage furniture, leather, clothing, and even books. On the flip side, if the air in your home is too dry, you risk having cracked floors, plaster, leather, and furniture. A humidistat allows you to prevent either extreme. 

Setting the Humidistat for Perfect Year-Round Comfort

controlling a humidifier with humidistat

Setting a humidifier with a humidistat should be easy. Automatic humidifiers, in particular, don’t even need your intervention. As long as the thermostat is working effectively and you’ve set the right indoor temperatures, the humidistat will automatically “read the room” and adjust relative humidity to optimal levels. 

However, if your humidistat is not automatic, you’ll need to feed in the settings manually. This, too, shouldn’t be difficult. Essentially, when you’re home, turn the unit “ON” and set the thermostat to the desired temperature. If going away for an extended period (such as on vacation), all you have to do set the humidistat to a slightly lower reading. 

For manually-operated humidistat units, when you’re home, the recommended setting for the summer is 35 to 45 percent. Since the colder season can be drier, the recommended humidity setting for winter is about 55 percent. All these are Relative Humidity (RH) values. Also, remember that you may need a higher RH if there are more people in the room. 

Cleaning and Maintaining the Humidifier

For the optimal functioning of the humidistat, the humidifier must work without any issues. Keeping the humidifier clean and well-maintained, therefore, is imperative. The following cleaning and maintenance tips should help;

  • Only use distilled or demineralized water: Tap water contains mineral traces that can create deposits in the dehumidifier and promote bacterial growth. Some of the minerals might even find their way into the air you breathe, causing health complications.
  • Change the water regularly: For small, portable humidifiers, the water should be changed daily. For larger humidifiers, the water can be changed once every two weeks or as recommended by the manufacturer. 
  • Clean the humidifiers often: Small, portable humidifiers should be cleaned at least once every three days with a 3% hydrogen peroxide solution. Rinse the water tank with tap water after cleaning.
  • Change the filters regularly: The manufacturer manual will tell you how often to change the filters. If you can’t find any directions on that, change the filters once weekly, unless it’s a washable/reusable filter.

Wrap Up

If you can follow the above guide, finding and buying the right humidifier with a humidistat shouldn’t be difficult. We want to stress two things. First, always consider humidifiers where the humidistat is in-built or included as part of the package. Stand-along humidistat units create new, unnecessary challenges. Secondly, consider automatic humidistat units. They make humidity and indoor climate control more convenient.
