The first step in sizing a steam humidifier is to understand the space that needs to be humidified. This includes the square footage of the room, the height of the ceilings, and any other factors that might impact humidity levels. Once you have this information, you can start looking at different steam humidifiers and their capacity levels.

It’s important to find a humidifier that can handle your specific space without overworking itself.

  • Determine the total volume of air that will be humidified on a daily basis
  • This is typically done by calculating the cubic footage of the space to be humidified and multiplying it by the number of air changes per day
  • Once you have determined the total volume of air to be humidified, select a steam humidifier that has a capacity greater than or equal to this figure
  • It is important to note that not all steam humidifiers are created equal and some may require more maintenance than others
  • Choose a model that best fits your needs and budget

Humidification Calculation Formula

If you have ever wondered how to calculate humidification, there is a formula for that! The calculation for humidification is actually quite simple and only requires a few pieces of information. To start, you will need to know the current temperature and relative humidity.

From there, you can plug those numbers into the following equation: (Td-Tw) x 0.62 x Vh x %RHa = Gg/lb Let’s break down each piece of this equation so it is easier to understand.

Td is the dewpoint temperature, which is the temperature at which water vapor condenses into liquid water. Tw is the wet-bulb temperature, which takes into account both the air temperature and the evaporative cooling effect of water vapor on a thermometer’s bulb. Vh is the volume of air being humidified (in cubic feet), and %RHa is the desired relative humidity increase (expressed as a percentage).

Finally, Gg/lb is the pounds of moisture needed to achieve your desired relative humidity increase. Now that we have gone over all of the elements in this equation, let’s try it out with some example numbers. Say we have an 80 degree room with 50% relative humidity and we want to raise it to 60%.

Here’s what that would look like plugged into our equation: (80-68) x 0.62 x 1,000 ft3 x 10% = 11.48 lbs So in order to raise the relative humidity in our 1,000 cubic foot room by 10%, we would need 11.48 pounds of moisture.

And there you have it! This simple calculation can help you determine how much moisture you need to add in order to achieve your desired level of relative humidity.

Dehumidifier Size Calculator

When it comes to dehumidifiers, size does matter. That’s why it’s important to use a dehumidifier size calculator when choosing a unit for your home. There are a few factors that go into determining the appropriate size dehumidifier for your space, such as:

– The square footage of the room or area you want to dehumidify – The level of humidity in the air – The number of people occupying the space

With these factors in mind, you can then use a dehumidifier size calculator to figure out what capacity unit you need. For example, a small room (up to 500 square feet) with low humidity levels may only need a 20-pint dehumidifier. But if that same room has high humidity levels or is occupied by more than two people, you’ll likely need a larger 30-pint unit.

Ultimately, using a dehumidifier size calculator is the best way to ensure you’re getting a unit that’s properly sized for your needs. This will help improve the efficiency of your unit and make sure your space is comfortably free of excess moisture.

What Size Humidifier for 1,200 Sq Ft

If you have a home that is 1,200 square feet, you will need to purchase a humidifier that can cover that much space. There are many different types and sizes of humidifiers on the market, so it is important to do your research to find the one that will work best for your needs. One type of humidifier that would be suitable for a 1,200 square foot home is an evaporative humidifier.

These types of humidifiers work by pulling air through a wet wick, which then evaporates the water into the air. Evaporative humidifiers are very efficient and can cover large spaces. Another option would be a whole-house humidifier, which is installed directly into your HVAC system.

Whole-house humidifiers can also cover large spaces and provide consistent humidity levels throughout your home. If you are not sure what size or type of humidifier to purchase for your 1,200 square foot home, consult with a local HVAC contractor. They will be able to assess your needs and recommend the best solution for your space.

Dristeem Humidifier Sizing

Dristeem humidifier sizing is determined by a number of factors, such as the size of the room, the amount of humidity required, and the type of humidifier. The first step is to determine the size of the room. The next step is to determine the amount of humidity required.

This can be done by using a hygrometer or by measuring the relative humidity with a wet bulb thermometer. Once you have determined the size of the room and the amount of humidity required, you can then select a Dristeem humidifier that is appropriate for your needs.

How Do You Know What Size Humidifier to Get?

When it comes to humidifiers, size really does matter. The general rule of thumb is that you should choose a humidifier that is sized for the room in which it will be used. But there are a few other factors to consider as well when choosing the right size humidifier for your needs.

The first factor to consider is the square footage of the room. A good rule of thumb is that for every 100 square feet, you will need one gallon of water per day. So, if you have a 500 square foot room, you would need a five-gallon humidifier.

Another factor to consider is the level of humidity you want to maintain in the room. If you only want to raise the humidity by a few percentage points, then a smaller unit may suffice. However, if you are looking to maintain high levels of humidity (70% or higher), then you will need a larger unit that can output more moisture into the air.

Finally, keep in mind that some rooms are simply tougher to keep humid than others. Kitchens and bathrooms tend to have less humidity because of all the cooking and showering that goes on in them, so these rooms may require a larger unit even if they aren’t particularly large in square footage.

What Size Humidifier Do I Need Per Square Foot?

Assuming you’re talking about a whole-house humidifier, there are a few factors to consider when determining the size unit you need. The Association of Home Appliance Manufacturers (AHAM) has a rating system that rates whole-house humidifiers by their output in gallons per day (GPD). To calculate the GPD needed for your home, first determine the volume of your home in cubic feet.

This can be done by measuring the length and width of each room and multiplying those numbers together. Once you have the total volume, multiply that number by 0.133. This will give you the number of gallons of water your humidifier will need to add to the air each day in order to maintain proper humidity levels.

For example, if your house is 2,000 square feet, it would have a volume of 2,000 x 2,000 x 8 = 32,000 cubic feet. 32,000 x 0.133 = 4,256 gallons per day required output from your humidifier unit. Another way to determine sizing is by using AHAM’s Daily Moisture Removal Chart which takes into account both the size (in square footage) and climate zone of your home:

Home Size Average DailyMoisture Removal Rate(pints/day) Recommended Output Capacity(gallons per 24 hours)

How Do You Size a Hvac Humidifier?

Adding a humidifier to your HVAC system is a great way to improve indoor air quality and comfort, but choosing the right size unit is essential for optimal performance. There are a few key factors to consider when sizing a humidifier for your home or business, including: -The square footage of the space you want to humidify

-The climate and weather conditions in your area -The number of people typically occupying the space -The type of HVAC system you have

Using these criteria, you can narrow down the list of potential humidifiers and choose the best one for your needs. For example, if you want to add humidity to a large space that experiences extreme temperature changes throughout the year, you’ll need a different unit than someone who wants to maintain comfortable humidity levels in a small office with relatively stable temperatures. When it comes to HVAC humidifiers, bigger is not always better.

A unit that’s too large will waste energy and money by producing more moisture than necessary, while a unit that’s too small will struggle to keep up with demand and may lead to premature wear and tear. The best way to find the perfect size for your needs is to consult with an HVAC contractor or specialist who can help you select the right model based on the specific conditions in your home or business.

What Size Humidifier Do I Need for 800 Square Feet?

If you’re looking for a humidifier to cover 800 square feet, you’ll need to find one with a capacity of at least 2 gallons. A 2-gallon humidifier can cover an area of up to 1,500 square feet, so it should be more than enough for your needs. When choosing a humidifier, it’s important to consider the features that are most important to you.

If you want a unit that is easy to clean, look for one with removable parts that can be washed in the dishwasher. If you have allergies or asthma, choose a unit with an air filter to help remove contaminants from the air. And if you want a unit that is energy-efficient, look for one with an automatic shut-off feature that will turn the unit off when the desired level of humidity has been reached.


A steam humidifier is a great way to add moisture to the air in your home, but it’s important to choose the right size for your needs. The size of your humidifier will depend on the square footage of the space you’re trying to humidify, as well as the level of humidity you want to achieve. A small humidifier might be enough for a single room, while a larger unit will be better suited for a whole house.

Once you’ve determined the size of humidifier you need, it’s important to also consider the features that are available. Some units come with built-in timers and thermostats, which can help maintain a consistent level of humidity. Other models include filters that help remove impurities from the water before it’s released into the air.

When choosing a steam humidifier, be sure to consider all of these factors to find the best unit for your needs.
