What Is a Humidifier?

A humidifier is used to maintain the moisture level inside your home. It is important to have a good moisture level inside the home because it reduces health risks due to respiratory diseases such as bronchitis and sinusitis.  By adding moisture to the air inside your home humidifiers also keep you comfortable instead, and preserve the wooden furniture inside your home. 

There are two types of humidifiers. Point-of-use humidifiers are used to control the moisture level in a single room or a small area. Whole-home humidifiers are meant to control the moisture in a larger area covering several hundred square feet, and, as the name suggests, an entire house as well.

What Are the Types of Whole-Home Humidifiers?

Whole-Home  humidifiers can be classified into three broad categories:

Bypass: Bypass Humidifiers use hot air from the HVAC system of the house to create moisture by passing it through water

Fan-based: This kind of humidifier you got a fan built into the system to blow air across a water panel which is then sent into the HVAC unit of the house Tu to maintain the moisture level in all areas.

Steam-based: As the name suggests the humidifiers generate steam by boiling water and then blow the steam across different areas of the home through the help of a blower.

They can also be classified as per their working systems:

Drum: Drumbeat humidifiers use a fabric belt Run over a rotating drum to capture moisture above the source of water which is then circulated across the entire house

Spray Mist: Spray Mist humidifiers spray the moisture in the AC duct as and when the AC or furnace comes on 

Flow-Through: These are similar to drum-based humidifiers, except that they used in an evaporator instead of a rotating drum.

Features to Look For in a Whole-Home Humidifier

Area Covered

While for small houses whole-home humidifiers that cover 1000 to 2000 square feet would be enough if your house is a larger one you might consider getting a more powerful machine that is capable of covering more than 4000 square feet such as the Honeywell HE360A


If you are living in an area where humidity is an issue you would ideally want a humidifier that can run for a longer period without having to do any kind of maintenance. While some humidifiers can work at a maximum stretch of 24 hours only there are others that can run up to 48 or even 72 hours at a stretch


While small humidifiers are typically easy to install and can be done by yourself, for larger humidifiers you might need professional help and you may also need to buy a separate installation kit altogether. Consider whether you will be able to install the humidifier on your own or you would need help.


Does the humidifier have an auto cut-off system or do you need to keep watching the settings at all times? How long before the wicking filters need to be changed? Are spare parts easily available?  you may need answers to all of these questions before deciding to buy a humidifier unit.

Capacity & Size

The capacity and size of the humidifier refer to the size of the tank which holds the water (which is necessary to create moisture used by the humidifier to moisturize the air in the house).

There are models that can hold only three gallons of water, and then there are others at the larger end of the spectrum which can hold up to 9 to 10 gallons as well.

If your house is larger in size than average, consider buying a humidifier that can hold more water but also check whether the tanks are easy to fill and clean. If the tanks are not easy to fill then it can be a major pain area for you going forward


The cost of the humidifier will always be a factor in making the final decision.

Make sure to not make this buying decision purely based on budgetary constraints because a humidifier that is simply not large enough to cater to the requirements of your home, even though you may have spent a good amount on it, will end up being nothing but an eyesore and a hole in your pocket.

Take careful note of the size, capacity, and square footage parameters of the model that you are buying before making any decision.
