How to Buy the Best Steam Humidifiers

How to Buy the Best Steam Humidifiers

Photo: Vicks

1. Types of Steam Humidifiers: Room Model or Whole House

You will need to decide whether you want a steam humidifier that can humidify the entire house or just one room. This choice depends on your specific needs, but each of the two types has its merits and demerits.

Room Model

Room steam humidifier models are designed for humidifying single rooms like bedrooms and offices as they will not have a very wide coverage. These models are more compact and highly portable to allow you to move and use them in different rooms.

The room models like the Vicks V105SG will also not require any permanent installation or complicated setup, which makes them super easy to use.

However, they have a limited runtime and coverage when compared to the whole house types. And they will also often have smaller tanks that are typically under 5 gallons, which means they need more regular refills.

Whole House

The whole house steam humidifiers like Aprilaire 800 are larger and more powerful models that are designed to spread the warm mist throughout the house. This eliminates the need to have a different humidifier in every room.

These models will cover spaces up to 10,000 square feet and will also have more advanced features and sturdier build to ensure they will serve you longer. Also, these units have a relatively lager tank capacity.

For the drawbacks, they tend to be more expensive and will be a little more hectic to maintain when compared to the room models.

2. Water Tank Capacity

If you opt for the stand-alone humidifiers with a built-in water tank, you will also need to check the capacity as it will determine how often you will need to refill the appliance.

You can get a model with as little as one gallon tank or even less while some more expensive ones will have massive tanks that can hold tens of gallons.

Large tanks are more convenient as they will reduce the frequency of refills. But also keep in mind that water use differs among different models, and so some will use up the water relatively faster regardless of the tank size.

3. Mist Output

The amount of mist that the unit will put out into your air also matters as it is what determines its effectiveness and efficiency.

Mist output is largely dependent on the water tank capacity, and so for many units the two will be the same. However, for the whole house systems that will be connected directly to the water supply in your house, you need to check how much mist the unit can put out every 24 hours.

There is no right or wrong mist output as it depends on just how dry the air is and your preferences, but something that can put out at least 5 gallons of mist every day should be good enough.

4. Coverage Area

The exact coverage area of the humidifier will also matter as it will determine whether it will be adequate for your room or entire house.

For room humidifiers, the size of your room should help you decide the right model to buy. That said, some users will be okay with 100 to 500 square feet coverage provided by the Vicks V105SG, while others might want something larger than this.

However, if you want something for the whole house, you need something that will cover at least 1,000 square feet like Vornado HU1-0062-43, but the actual model you need depends on the size of your house.

5. Noise Level

Noise level is a big concern when choosing a steam humidifier because you do not want something that is too loud as it will make it hard to sleep.

Hence, as you pick up a model, you need to check the noise rating. Here something with under 50 dBA noise rating should be quiet enough for you.

6. Extra Features

The best warm steam humidifier for you is one that will include a few extra features to enhance its functionality and versatility.

These extra features are however not necessary for the appliance to work but are still very useful. They will include things like an essential oil diffuser, built-in timer, automatic sleep mode and a remote control.

7. Ease of Use and Cleaning

The humidifier you choose needs to give you an easy time when it comes to the use and cleaning. Some simple and easy to understand controls will ensure you can easily choose your preferred settings.

A removable tank with a wide opening and can fit under a facet will also give you an easy time as it makes water refills a breeze. And to make cleaning easy, the surface should be easy to wipe down and the removable parts should be dishwasher-safe.

Conclusion 

Steam humidifier will not only keep your air moisturized but also warm it up a bit to make the house even more comfortable. And now finding the best steam humidifier is all about picking one model from our list.

From our reviews, the Vornado HU1-0062-43 is our best overall model thanks to the efficient vortex action and customizable settings.

But, if you want something small and portable that also does not cost much to buy, the Vicks V105SG should meet your needs.
