Humidifiers are a great way to maintain humidity levels indoors. A humidifier improves the comfort and the overall health levels indoors by injecting moisture in the air in the shape of invisible mist.

The boost in the humidity levels indoors helps in safeguarding the health of the family and protecting the structure of the home from dry air.

Humidifiers are more popular during the winters because the product helps in combating the physical discomforts caused by the weather. Winter brings with it a series of diseases that affects the young and old alike. By adding moisture in the air, the humidifier prevents the drying of hands and the formation of respiratory conditions common during the winter.

The concept of humidifiers is easy to understand. However, the same cannot be said for choosing one.

There are many types of humidifiers available today. Some units use evaporative technology to humidify a place while others use ultrasonic or straight-mist mechanisms. Humidifiers have different varieties too,  with each providing convenience to a different segment of consumers. Portable humidifiers and whole-home humidifiers are an example of the types available as each provides unique benefits to users.

Therefore, as a consumer, the first question that comes to the mind is the type of humidifier you need. The answer to the problem lies in assessing your need for a humidifier and then deciding the one that fulfills those needs perfectly. There could be a medical condition or the overall uneasiness during the dry winter season that may prompt you to consider the idea of choosing a humidifier.

Once you have decided on the type of humidifier, you need to ask yourself the second and the more important question regarding the size of the appliance. The size of a humidifier depends directly on the space where you intend to use it for.

What Size Humidifiers Do I Need for My House?

There are a lot of factors that you need to consider when deciding the size of the humidifier. To ensure that you make the right decision, we have made a list of the factors you need to consider when choosing the Humidifier size.

1. Square Foot- The Room Size and the Area You Need It From

Most humidifiers mention the intended room size for each model, this is crucial because square feet is the most important of all factors.

In addition to the intended room size manufacturers state the amount of moisture the humidifier adds to the air. The moisture output is usually mentioned for 24 hours.

Although the details mentioned on the humidifier are more or less accurate, you need to go for a bigger humidifier size in case of doubt.

If the specifications suggest that the humidifier will work for a room size 400sq.ft while your room actually is 360sq.ft, choose a medium size model.

2. Room Insulation- Resistance to the Flow of Heat

Once you are done measuring the square feet, you need to divert your attention to the room insulation.

It is essential to know the insulation of the room. The amount of air in the room determines the choice of humidifier size.

A humidifier circulates air in the room X number of times/hour.

Homes or rooms that are airtight usually have insulated walls and draft-free exterior doors and windows. On the contrary, drafty homes are not airtight. While humidifying a zone or a room that contains a fireplace, ensure that the damper is closed.

3. Room Volume- Volume of the Sections of Room

Every house is different. Some rely on high ceilings, while others depend on vaulted ceilings. Having ceilings that are higher than average will result in you under-sizing the humidifier. This is one of the disadvantages of following humidifier-size charts.

The major flaw with these charts is that they are made with standard ceilings size in mind. With each house having its own types and sizes of ceilings, it is crucial to have an idea of room volume when choosing the size of the humidifier.

4. Humidification Load- Calculation of the Load of Humidification

For those who don’t know the term humidification load implies the amount of moisture needed in the air to achieve a healthy level of relative humidity.

Scientists and experts believe that a healthy RH level ranges from 40-60 percent.

Many factors play a crucial role in the humidity indoors. The presence of drafts and the temperature indoors are the factors that contribute significantly to the indoor levels of humidity.

The number of people in the home and the activities they pursue throughout the day are secondary factors that affect the humidity levels. The more the people inside the house, the more the levels of humidity while activities such as showering and cooking also lead to rising humidity.  

5. Gallons per Day- The Rate of Moisture Output

Gallons per day refer to the moisture output levels. The GPD varies widely from one humidifier to another.

The manufacturer uses two ways to determine GPD. In the steam-type humidifiers, the amount of water that evaporates in the air is used to calculate the GPD.  Other types of humidifiers, however, calculate GPD by the amount of moisture that passes through the humidifiers media.

Portable Humidifiers vs. Whole House Humidifiers- Types of Humidifiers

As discussed earlier, the type of humidifiers falls into two categories. As the name suggests, the user can move portable humidifiers from room to room, this helps in providing zone humidification to a single place.

Whole-home humidifiers are relatively more straightforward; these products are responsible for the humidification of the whole home. Home humidifiers just like portable humidifiers come in two sub-categories.

Stand-alone humidifiers are stationary humidifiers that provide 24-hour humidification with the help of a sink connection.

Furnace humidifiers, on the other hand, are installed on a furnace, as the humidifiers have a dedicated water line of their own.

1. Cool-Mist or Impeller Humidifier

Cool-mist or impeller humidifiers are products that come with a reservoir and a spinning disc. The spinning disc is responsible for breaking up water particles and turning them into a fine mist.

The quiet sound input of the humidifiers has made the Impeller amongst its users.

2. Warm Mist or Steam Humidifiers

The steam mist does not come with a spinning disc; the product instead has a heating element of its own. The heating element in the humidifier raises the temperature of the water in the tank to boiling point. Once the water boils, the humidifier releases warm steam in the air.

3. Evaporative Humidifiers

Evaporative humidifiers contain a filtering wick. The highly-absorbent wick soaks up water in the reservoir. The humidifiers fan then blows across the filter, spreading moisturizing mist in the room.

4. Ultrasonic Humidifiers

Of all the four types of humidifiers in the list, the ultrasonic humidifier is the quietest. The two ceramic plates in the humidifier vibrate at a high frequency, converting water into ultra-small droplets

The product, however, needs demineralization to prevent it from creating the white mineral dust that settles in the room.

Humidifier by Room Size- Humidifier Size

If you have an airtight room that has ceilings which are 8 to 9 foot high, then you are safe from making complex calculations. The rough guideline given below is enough to help you choose the humidifier size.

Small Rooms

Until or unless the manufacturer suggests otherwise small rooms usually means room measuring less than 400sq.ft. Typically, rooms such as the kitchen or bathrooms fit into this category. Small rooms need compact and tabletop humidifiers, as they can produce up to 1.5 to 4 gallons of moisture.

The humidifiers for small rooms don’t take up much space and have permanently affixed reservoirs.

Medium-Size Rooms

Medium-size rooms range from 400 to 1000 square feet. Bedrooms, large kitchens, or small dens occupy this category.

Tower-style humidifiers that are kept on the floor are ideal for such rooms. The majority of tower humidifiers put out 2-4 gallons of moisture. The tanks are removable, making it convenient for the user to refill the tabletop humidifier.

Large Rooms

A stamp of “large room” on the humidifiers means that the unit works effectively on rooms bigger than 1000 sq. ft.

Tower humidifiers that have a moisture rate that lies in the upper quartile of the 2 to 4 gallons of moisture are ideal for large rooms.

In addition to the tower, humidifier users also have the option of console humidifiers. Console humidifiers boast of an output rate that is approximately double of the tower humidifiers. Although console humidifiers are much heavier, they are movable.

Console units have an output rate of 6 to 8 GPD. This makes the products ideal for dual-room or open-room humidification.

Entire House

Currently, no portable humidifier can provide an entire home with moisture. Rather than choosing portable humidifiers, you need a whole-home humidifier.

The large console humidifiers can release up to 9 gallons of moisture per day. If you live in an apartment of up to 2,500 sq units, you can humidify your whole place with the help of a single console unit.

However, if you live in a house that ranges from 2500-4000 sq. ft, you will need to install a duct or furnace humidifier.

Duct or furnace humidifiers are explicitly designed for whole-home humidification. Installing the units in the existing HVAC will ensure that each and every portion of the house is moisturized at the same time.
