Top 5 Best Humidifiers for the Furnace in 2019: Buying Guide

Winter tends to bring low humidity. This is due to the cold temperatures, which create dry air. When there is dry air, there is no moisture, and this leads to things like colds and the flu, along with allergies.

Best Humidifier for the Furnace

When buying a humidifier, you have plenty of different options to choose from. This article is concerned with a humidifier that can work directly with your furnace. One that connects to both your heating unit and water line.

In this short buying guide, we’re going to be taking you through the key factors that must be considered, along with why you should make this investment.

Why Should I Purchase A Humidifier For My Furnace?

Regular humidifiers are great. No one is denying that. They work very well, and for their purposes, they are more than ideal. But, there is one small “problem”, you might say.

The problem is that most air humidifiers can only work within a single room. Not the entire house. So, if you want to add the necessary humidity to your home, you’re going to have to either buy multiple humidifiers or invest in a humidifier that can humidify your entire home.

When you add that necessary humidity to your home, several things happen.

First, the air becomes far more moist, which lessens allergies and symptoms of things like colds and coughs.

Second, if you are already dealing with some kind of sickness – especially if it’s directly related to the dry air – it becomes far less potent, making it easier for your immune system to get rid of it. For example, if you have a runny nose, your nasal passages will become far more moist with a humidifier, which gets rid of your runny nose.

Third, things like houseplants, and even the wood that makes up your floors, become a lot healthier and sturdier. With the dry air, house plants often suffer from a lack of moisture. The same is true of wood.

Now, if the wood in, say, your floors doesn’t have enough moisture, it can begin to degrade. Things like shrinking are quite common. If this is left unchecked, it can easily cause some very nasty damage.

The Type Of Furnace Humidifier You Are Purchasing

There are three types of furnace humidifier that you can find.

A steam humidifier is by far the most popular type of furnace humidifier. Now, steam humidifiers are unique in the fact that they produce both cool mist, as well as warm mist. Because of this, they are the furnace humidifier that produces the most moisture, overall.

Flow-through humidifiers take the warm air that your furnace produces, and they allow warm water to trickle over it. This leads to evaporation. One of the notable things about flow-through humidifiers is that they are very, very low-maintenance, and there is no risk of mold.

Finally, we have drum humidifiers. Drum humidifiers use a large pan that is full of water, as well as a belt that rotates and passes through this pan. All of the water on the belt then evaporates. Now, this particular furnace humidifier does require you to clean the pan on a regular basis. If you fail to do so, it can easily lead to mold.

Each one works well with any kind of furnace, but you need to consider what your needs are.

For example, steam humidifiers are great, but they do use a lot of electricity, and as such, they can be more expensive.

On the other hand, flow through humidifiers are a bit cheaper, but they only produce warm mist. If you want the option for cool mist, then a flow-through humidifier isn’t ideal.

With a drum humidifier, you have a humidifier that works very well but does require a fair amount of regular maintenance. And, of course, there is the risk of mold.

Maximum Area Coverage

Whether it’s an air purifier or humidifier, this is a BIG factor that must be considered.

Most furnace humidifiers have a Maximum Area Coverage of at least 1500 feet. Some have less, but most have around that, or more.

But, depending on how large your home is, this might not be enough. And if you don’t know the size of your home, it’s always wise to choose a furnace humidifier that has a large Maximum Area Coverage.

However, no matter the size of your home, there will be a furnace humidifier that is right for you. You have access to humidifiers with a Maximum Area Coverage of 3000 feet, and even up to 8000 feet, if not more.

Naturally, though, if your home is especially large, then you will have to pay some extra money for a furnace humidifier that can accommodate that particular space and its abnormal size.

Daily Output & Control Over This Output

Most furnace humidifiers measure their daily humidity output in gallons. Some produce 19 gallons per day. Others produce 12 gallons per day. Every furnace humidifier is different.

What you want to consider is both the output and the kind of home that you live in, as well as the space that the furnace humidifier is designed for.

If you are living in a home that is two-thousand square-feet, and the furnace humidifier you are using is designed for three-thousand square-feet and produces 20 gallons of humidity per day, then that humidity will be spread around your home in fairly large quantities. You might get too much of it. Or, depending on the furnace humidifier and the space, too little.

More often than not, it’s good to go for the furnace humidifier that can accommodate a bigger space with a bigger output. Usually, you have many options when it comes to how much humidity is being produced. This is especially important if you know the necessary humidity levels.

Make sure that you have access to the daily humidity output. This means that you know exactly how much humidity is being produced, and what humidity levels work best for you.
