Best Humidifier For Medium Room

What is Considered a Medium-Sized Room for a Humidifier?

Mid-sized rooms typically range from 400 square feet to 1,000 square feet. Large kitchens and bedrooms are standard examples of mid-sized rooms.

Small rooms comprise kitchens, bathrooms, and related indoor spaces. Small-sized rooms measure less than 400 square feet and require humidifiers with few performance features.

Large-sized rooms measure more than 1,000 square feet and need humidifiers that can dissipate large amounts of moisture per hour to humidify the air effectively.

How do you Size a Humidifier for a Room?

Sizing a humidifier for a room entails taking into consideration several factors as outlined below.

The area of the room

The room area, which is expressed in square feet, is a good indicator of the size of a humidifier that one needs. Generally, you can use humidifiers that are designed for small, medium, or large rooms.

The height of the ceiling

The height of the ceiling determines the volume of air that needs to be humidified at any time. Rooms with high ceilings require humidifiers with matching high output than those with a low ceiling.

The insulation level of the room

Room insulation determines the level of humidification needed to keep the air inside your home ideal for breathing. If a room is poorly insulated, a lot of air moves in and out. This means that you will need higher humidification to fight off cold and dry drafts that keep flowing inside the room.

On the contrary, it is easy to humidify the air in houses that are correctly insulated. If your room is poorly insulated, you will need a humidifier with a high-performance capacity.

Things to Consider when Choosing a Humidifier

Choosing a humidifier is easy if you understand a few basic things about these devices and know what you are looking for. Here are a few things that you should always consider when choosing a humidifier.

The level of maintenance required

Maintenance of a humidifier entails daily cleaning of the water tank, thorough cleaning of the entire device, and occasional checking of every part. Generally, cleaning a humidifier follows a standard process, but the steps’ intensity varies with the model.

Some models, especially those that have filters, need more detailed cleaning and maintenance procedures than those humidifers without filters. Hence, ensure that you check the humidifier’s technical features that you intend to purchase to determine its cleaning requirements.

The noise levels

Humidifiers produce some noise when they are running. The noise level of humidifiers varies considerably and depends on their mechanical design. The best humidifiers are those with a noise level of less than 30 dB.

Go for humidifiers that are ultra-silent when operating if you would like to place them in bedrooms. Some humidifiers have the sleep mode feature that ensures that they produce very little noise at night. Such humidifiers can also be the best pick for you if you would like to place them in bedrooms at home.

The type of humidifier

There are three types of humidifiers, based on their mode of operation: cool mist, warm mist, and ultrasonic. Cool mist humidifiers disperse mist that is at room temperature. They use less electric power than warm mist humidifiers because they do not heat the water before vaporizing it.

Warm mist humidifiers require much more electric power than cool mist ones. This is because the water in warm mist humidifiers must be heated first before the mist gets dispersed.

Ultrasonic humidifiers are specially designed to produce the least amount of noise when operating. They exist in both cool mist and warm mist types.


Modern humidifiers have a range of inbuilt features, including a humidistat, water tank indicator, and auto shut off. The auto-shutoff feature helps protect the humidifier’s internal components from getting damaged if something goes wrong when the humidifier is working. The auto-shutoff feature triggers the humidifier to shut off instantly when the water tank is empty.

Humidifiers that have inbuilt humidistat are more convenient than those without. The humidistat helps the humidifier to automatically adjust its performance to the needs of the ambient air. Such humidifiers maintain the air’s humidity level within the recommended range of 40% to 60%.

The size and design of the water tank

The larger the size of the water tank, the more convenient it is to use a humidifier. Some humidifiers have large water tanks that can hold 6 liters of water when full, while others have smaller ones. Separately, it is easier to refill humidifier water tanks with top-refill designs than those with other types.
