Furnace humidifiers are super useful pieces of equipment which can help your home stay humidified throughout the cooler months.

On the most basic level, if you live in a very dry area, a furnace humidifier can be super useful during winter months when a cold or flu virus is going around your area and everyone is going around coughing.

During the winter, furnace humidifiers can help with dry skin, nose bleeds, cracking lips, and dry sinuses. Dry sinuses can cause ear aches during the winter, so a furnace humidifier is extremely useful for your workout routine.

Fortunately, these humidifiers are not super expensive and most humidifiers have built-in timers for convenience. Many also have filters to keep your furnace relatively clean.

However, with that said, not all humidifiers are created equal. There are a wide variety of humidifiers out there on the market which use different methods to output humidity. Some pump moisture into the air while others use a heating method.

But of course the most important thing is that the humidifier you choose match your home. We put together this comprehensive guide on the best furnace humidifiers and included helpful tips on how to use these humidifiers to boost your furnace humidity.

We really enjoyed testing the replacement whole home humidifier for the Aprilaire 400. We used it during the winter months as our furnace runs pretty frequently to help maintain our desired +/-50 humidity levels.

While humidifiers are typically good for sick people and people with allergies, it’s no surprise that you can use these humifiers for the aesthetic as well. Even on days of when the humidity levels are quite high outside, the “dry” indoor air in your house can be very uncomfortable.

Long story short, getting an Aprilaire 400 whole house humidifier is a great idea if you’re in a climate where the weather gets very dry in the winter months. You may even want to get two of these bad boys to help out in larger homes.

Frequently Asked Questions (FAQ)

What is the best humidifier for a furnace?

A furnace humidifier adds to the comfort of your home by increasing the air moisture levels.

The discussion can quickly become technical because there are many options which are designed to work with different types of furnaces. A good rule of thumb is to purchase a humidifier with a built-in pump that is meant to work with your exact make and model of furnace. Check the packaging and user reviews to decide which would be the best-fit for your furnace.

Are humidifiers on furnaces good?

Furnace humidifiers are the best way to keep your home comfortable during the winter and fall when the temperature drops, especially if you keep doors and windows closed throughout your house. Humidifiers spread the moisture evenly through the air, and as a result, increase the amount of moisture in the air.

In addition to this, the moisture in the air helps combat dust mites and allergens in your home that are in the air and keep it more comfortable for you to breathe.

What percent should I set my humidifier?

According to the experts, you should keep your moisture level between 30 and 50 percent. If you know the percentage of dryness in your area, you can adjust accordingly. You can easily test the humidity level in your home by checking the amount of moisture on a bathroom mirror every day. If you can see your reflection or leave a trace, you should increase the amount of moisture in your home. Those with allergies may want to keep their home humidifiers set to 55 to 60 percent.

Do high efficiency furnaces need humidifiers?

If you have a high-performance furnace, then you can pretty much bet that it’s been designed to take in as much air as possible and provide maximum back-vented ventilation in order to maintain consistent temperatures. Unfortunately, this cold air can sometimes dry out your lungs and sinuses. For those with high-efficiency furnaces, investing in a humidifier is a worthwhile decision.


If your home or business has a furnace, and you are experiencing a wintertime dry spell, it might be time to purchase a furnace humidifier. This will help you improve air flow, reduce static, and rob dust and debris, too. We’ve reviewed the top five furnace humidifiers on the market below. We hope you find the information helpful as you look to increase the quality of air in your home and business.
