A humidistat, also known as a humidistat control or hygrostat, is a humidity monitoring tool that helps keep your home at the optimal level of humidity.

What is Humidistat?

A humidistat is an electronic device that monitors and controls the level of humidity in your home. It measures the relative humidity of the air and then uses this information to automatically adjust the amount of moisture in your home. They are an important part of any HVAC system, as they help to reduce allergens, promote more comfortable temperatures, and prevent mold growth.

How does a humidistat work? 

Humidistats measure relative humidity (RH) levels and compare it to a set “target” level set by you. When the RH exceeds or drops below the target range, the humidistat will turn on or off a device such as an evaporative cooler, dehumidifier, or fan. This allows you to regulate the amount of moisture in your home, which can help reduce allergens and improve comfort.

What are the benefits of using a humidistat?

Humidistats provide consistent humidity control throughout your home. They also help prevent mold growth by removing excess moisture when it is detected. In addition, they can make your air more comfortable to breathe by reducing indoor allergens such as dust mites and pet dander. Finally, having a humidistat can save energy costs since it only runs when needed to maintain the optimal RH level. 

What should you set your humidistat to?

The ideal relative humidity for comfort is considered to be between 30% and 60%. Depending on the climate you live in and other factors like the age of your home, this range may need to be adjusted. If you feel uncomfortable when the RH level drops below or rises above this range, it’s best to consult a professional HVAC technician. Note that mold starts forming at humidity levels of 68%.

Is a humidistat necessary?

Having a humidistat can be helpful in maintaining the right humidity level in your home. It is especially important if you live in an area with high levels of humidity, as this may lead to mold growth and other problems. Additionally, having a humidistat can help keep you more comfortable by reducing allergens and providing consistent temperatures throughout your home. 

Overall, a humidistat can be a great tool for maintaining the optimal air quality and comfort levels in your home. It is an essential part of any HVAC system that will help save energy costs and reduce indoor allergens. With its easy installation, it is an affordable way to ensure that your home stays at the right level of humidity all year round.
