What Size Humidifier Do I Need?

Nowadays, there are a lot of humidifiers on the market that promise high-end features and functions, making it difficult to narrow down your best option. The concept behind a humidifier might be simple to understand, but the process of choosing one isn't quite as simple!  Let us look into humidifier size suggestions and factors for consideration to answer, “What Size Humidifier Do I Need?”.

How To Size A Humidifier

Sizing the humidifier to appropriately fit the size of your room is essential, as humidifiers are categorized by their suitable coverage area in square feet. Most, if not all, humidifier manufacturers indicate the intended room size for their model, and this is because the square footage is the most important factor to take into consideration when you are shopping for a humidifier.  If you get an underpowered humidifier, you either won't get the humidity level you want, or the humidifier will take much more time to reach the desired humidity level. 

Additionally, some people might get the right tank size; however, they forget about moisture output! The moisture output is rated in gallons, and describes how much water will be dispersed into the air during its use. A higher moisture output means a more efficient humidifier. The moisture output rate (in gallons) is more or less accurate if the humidifier is used within the square feet listed in the manufacturer's specs. Remember that if you are in doubt that a humidifier will work for your home or room's size, go for a slightly bigger model. 

If you have other concerns regarding your ideal humidifier, be sure to refer to our humidifier buying guide, which dives deep into all of the information and features you need to look out for when shopping for a humidifier.

What Size Humidifier Do I Need For My House?

There is no perfect answer for this question, as the humidifier size is going to depend on how big your house actually is. You will need to measure your house, taking into consideration your current and desired humidity levels. The less humid your house is, the higher moisture output rate you will need. However, we recommend that most homes start with a humidifier that can cover at least 800 square feet and has a minimum of a 7 gallon tank capacity.

What Size Humidifier Do I Need For My Bedroom?

Similar to selecting a humidifier for your house, the answer to this question will depend on the actual size of your bedroom. However, there is one key difference: in your bedroom, you may also want to consider the humidifier's noise level. Almost every humidifier will produce some level of noise, but some humidifiers are quieter than others. Aside from size, this is a factor that you should consider when looking for a humidifier, since the bedroom is where you're going to sleep and relax. Having a humidifier that's uncomfortably loud will hinder you from getting the rest you need. Infants and children are also more sensitive to noise than adults, and will greatly benefit from using a more silent humidifier.
