Humidifier With Hygrometer: What Is It And Do You Need It?

Dry climate conditions are as common as humid ones around the world. Humidifiers help to combat that dryness by adding moisture to the dry air. But, of course, you want to make sure you don’t introduce too much moisture. Thus, manufacturers created the humidifier with a hygrometer. 

Humidifiers with hygrometers help users in 2 ways. Firstly, they help them set the humidity level they want for the room, and the humidifier works to achieve that desired level. Secondly, they make sure that the humidifier doesn’t go above the set level. So, it doesn’t raise the humidity to a point that it may be a health concern for anyone with breathing problems.

Sometimes smaller humidifiers are all you need.

A humidifier is a device that adds moisture to the air. Used in dry climates, it eliminates dryness and provides relief for:

  • Dry throat and cough
  • Dry skin and cracked lips
  • Nose irritation
  • Headache and sinus congestion

Adding moisture to the air ensures you have a healthy living environment in dry conditions. While there are many different types of humidifiers, the 4 most popular types are:

  1. Warm mist: Produces a warm mist, used in the winters and for treating colds. 
  2. Cool mist: Used in warm, dry climates. Easy to clean but requires regular maintenance. Otherwise, mildew and mold may start to grow in the device.  
  3. Whole-house: A device that allows users to add moisture to the air throughout their home.
  4. Ultrasonic: Uses water droplets and a fan to add moisture to the air. Ideal for small rooms.

It is recommended you use a humidifier only when the environment in your home is dry. Adding excess moisture to an already humid space may be dangerous. Excess water in the air promotes bacteria, dust, and air pollutant growth. 

What is a hygrometer?

A hygrometer is an instrument used to determine humidity and moisture present in the air in a space. It may be used in a room or an open area. 

Extra moisture in the air is cause for concern. It may lead to health problems such as breathing issues and also increase the chances of allergies and asthma attacks. 

The moisture also promotes an environment for bacteria growth. This is directly linked to black mold and mildew. Black mold is a serious concern for your home if it is not dealt with immediately. It spreads quickly and to various parts of the house, including its foundation. It rots away the materials to the point that they decay. 

A hygrometer essentially helps you determine when humidity levels are high or low. Ideally, you want to keep moisture in the air between 30% and 50% in your home. At this level, bacteria and mold will be kept in check. 

Is a humidifier with a hygrometer common and useful?

A humidifier with a hygrometer is more common than you think since a hygrometer helps you to safely use a humidifier.

As previously mentioned, a humidifier adds moisture to the air. Too much moisture in the air can be a problem for individuals and their homes. So, a hygrometer is helpful in the sense that it notifies you when you’ve reached a humidity of 50% or more. At that point, you can turn off the humidifier, ensuring that you don’t make the space too humid. 

Top 2 humidifiers with a hygrometer option you should consider

Let’s look at the top three humidifiers in the market that have some form of hygrometer in them. 

1. LEVOIT Humidifiers 6L Top Fill Cool Mist


  • Easy to use, comes with a hygrometer
  • Controlled by an app as well as Alexa and Google Assistant
  • Reasonably priced


  • The device may develop bacteria and mold if you don’t clean it regularly

The LEVOIT Humidifiers 6L Top Fill Cool Mist is a smart device that works with your smartphone, Alexa, and Google Assistance. So, it is voice-controlled. All you have to do is download the Vesync app on your phone. 

It is one of the most powerful devices in its size category. It comes with a 6 liter (1.58 U.S. gallons) tank and works in a room that is up to 46.9 square meters (505 square feet). So, you can use it in large rooms in your home. The size of the tank allows it to function for up to 60 hours, depending on the setting of the device. 

The best part is that you get to set the level of humidity you want in the room. The device will work to raise it to that level and then stop. The built-in hygrometer lets it track humidity and ensure that levels don’t go above what you’ve set, which makes it easy to use and convenient. 

2. Paris Rhone 4L Cool Mist Humidifier


  • Well designed with a strong build
  • It lets you set the humidity level you want


  • Not suited for big halls
  • Can develop mold and mildew if you don’t regularly clean it

The Paris Rhone 4L Cool Mist is another great option for large rooms. It comes with a humidistat, which gives you the option to set the humidity level you want the device to work towards. It doesn’t come with the smart features that LEVOIT offers, but the device still gets the job done. 

Since it has a 4 liter (1.05 U.S. gallons) tank, it is more portable than LEVOIT. You can use it in a 29.9 square meters (322 square feet) room. So, it is perfect for bigger bedrooms or small halls.

The device is almost soundless, producing just 28 decibels of noise. By comparison, whispers are about 30 decibels. The noise it makes is equivalent to that of a soft whisper. So, you can easily use it at night. 

The device has a sturdy design with nano-coated inner components. For those who don’t know, nano-coating refers to a thin substance being applied to a surface to help prevent corrosion and other benefits. You can expect to use it for years to come.

A humidifier with a hygrometer or humidistat is more useful than you think. The device lets you keep track of humidity and ensure it doesn’t exceed the recommended amount. So, ultimately you make sure that your home has a healthy living environment.
