Just got a fancy humidifier but want to know how long it’ll take to work?
Most humidifiers will begin working in as soon as 15 minutes and can take anywhere from 3 to 24 hours to get to your desired humidity level.
Bigger room sizes and humidifier capacity can affect how soon your humidifier starts working.
If you’re wondering if it’s ok to sleep with a dehumidifier on or what is the best relative humidity to keep your environment at, you can find that all below.
Let’s get started.
How Long Does it Take for a Humidifier to Work?
For a small humidifier to start working, it can take around 15 minutes for it to start creating mist.
It can then take anywhere from 3 to 24 hours for it to raise the humidity levels to 30-50% depending on the size of your home.
If you’re running a whole-house humidifier, it can take up to 24 hours for it to affect your home’s humidity level.
Different Types of Humidifiers
Warm mist humidifier
A warm mist humidifier boils water and then releases the vapor created as steam. Since these units can run hot, they can be dangerous if left near children or pets. They also can make your room hotter which isn’t ideal in the summer.
Cool mist humidifier
Cool mist humidifiers are safer than their warm mist counterparts and don’t require as much energy to run.
A fan blows the mist around your home and doesn’t use a heating element which makes it better to use during the hotter months.
One downside is that they’re going to be a bit louder than warm mist humidifiers.
Ultrasonic humidifiers can produce either warm or cool mist by using a metal diaphragm that vibrates at a high frequency.
The sound then vibrates the mist into the air.
You won’t hear the vibrations as the frequency of the sound is much higher than the human ear can pick up.
After the microscopic water drops have been propelled into the air, the humidity levels will start to rise.
Factors that May Affect Your Humidifier’s Capacity
The biggest factors that are going to affect your humidifier’s capacity are the size of the area you want to humidify and how well your home is insulated.
If you’re running a three-gallon humidifier that’s rated for 1500 square feet but it’s running in a 2000 square foot space, it will take longer for it to be effective.
It can even be the case that in suboptimal conditions (like uninsulated spaces), your humidifier may not be able to add moisture to your space.
The best thing to do is to measure the room size want to humidify and then buy the right-sized unit.
