Best Whole-House Humidifier – Comparisons and Reviews

If the air in your home or office is a little too dry, you may want to think about purchasing a humidifier. Alternatively, if you suffer from cold-weather–related symptoms such as chapped lips and nose bleeds, a humidifier that puts moisture back into the air could alleviate your symptoms.

Our guide to the best whole-house humidifier will help you find the right pick for your budget.

What’s the difference between a humidifier with a diffuser and one without?

Humidifiers that come with a diffuser are designed to fill the air in your home with a scent that you love. Using essential oils, you can potentially make your home smell like calming lavender or invigorating peppermint. Humidifiers that do not come with a diffuser simply add more moisture to the air, which still helps to relieve those nasty cold-weather related symptoms and makes the air in your home easier to breathe.

Quick Look

How do you differentiate?

Humidifiers tend to differentiate in terms of capacity; for example, some humidifiers can hold 1.7 liters of water, whereas others are capable of holding as much as 6 liters. If you have a large home and you wish to increase the amount of moisture every room, a model that comes with a larger capacity may be best for you. Alternatively, if you have a small home, a model that comes with a smaller capacity may be just right.

Things to look for

Quietness––Some humidifiers are naturally louder than others, so if you plan on using your humidifier day after day, you may appreciate using a quiet one. Some humidifiers are as quiet as a refrigerator, whereas others are even quieter. The humidifiers that are “whisper quiet” are those that are so quiet that you can fall asleep without disturbance.

Anti-mold function––The anti-mold function is crucial as it can help reduce the likelihood of your home becoming damp and moldy. Furniture, wooden floors, and other surfaces are protected from mold, which means you can use your humidifier as often as you wish without worry.

How to make the most out of your new humidifier

The best way to make the most of out your new humidifier is to make sure that it always contains enough water. Many humidifiers can work for 24 hours without needing to be topped up, but if the air is particularly dry or you are suffering from some cold-weather–related symptoms, you may need to check your humidifier from time to time.

Do I really need a humidifier with an auto shut-off function?

Humidifiers that have an auto shut-off function are thought to be a lot safer than those that do not have this feature. With the ability to automatically shut itself off when there is no water left in the tank, the unit will neither overheat nor short circuit.

Most modern humidifiers come with this function, however there are still a few that do not. If you cannot be at home or awake when the water is likely to run out, you should make sure to either switch the humidifier off or be sure that it is completely full of water.

An auto shut-off function is convenient and makes it much safer to use, so if you come across a model that has this feature, you may want to consider buying it.

Prerequisites to using a humidifier

Humidifiers can be quite large, which means you will need to make sure you have enough room in your home for one. Some humidifiers can measure up to 21 inches in height and they can be as deep as 21 inches. Please make sure you have enough room in your home to house a humidifier before purchasing one.

You should ideally leave a gap of at least a few inches on every side of your humidifier so that it can work efficiently. Humidifiers that don’t have enough space to work may not work to their full effect, meaning you won’t benefit from using it quite so much. If you have a small home, please opt for a small whole-house humidifier so that it works to its full effect.
