There are many whole house humidifiers available online, but many of them over-inflate their value. We wanted to help you avoid these pitfalls by testing and reviewing six of the absolute best whole house humidifiers you can purchase today.

We will share with you the best whole house humidifier that we found and the features of all of them.

What is a Humidifier

A humidifier is a device that distributes water vapor throughout an environment to keep it from drying out.

Heaters and some air conditioning systems can leave you with dry air and uncomfortable to live within and a humidifier helps solve these problems.

Those that are especially sensitive to dust benefit from humidifiers as they can help reduce the irritability of the air in your home.

What Is a Whole House Humidifier?

A whole house humidifier is simply a type of humidifier whose effects can be scaled up to affect your entire household. Some humidifiers are targeted at humidifying single rooms, but our focus is those that can be used on larger spaces.

Some of the best whole house humidifiers are attached directly to the house’s HVAC system so that anyplace you can get air conditioning can also receive humidity.

Types of Humidifiers

Evaporative Humidifier

An evaporative humidifier is one of the simplest forms of humidifier. It essentially consists of three working parts: a reservoir of water, a wick, and a fan that blows across the wick.

The wick is a substance which is absorptive enough to draw water up from the reservoir.

It also needs to be porous enough that the fan can easily knock the water from the wick into the air as vapor. With these three elements, you really can get quite a bit of humidity flowing

Natural Humidifier?

Natural humidifiers are even more simple than evaporative humidifiers. They consist of only a wick and a reservoir, meaning they do not include a fan.

A houseplant is technically a natural humidifier, since it draws water up from its soil (its reservoir) and acts as a wick by losing this water into the air through evaporation.

Some people set up fans near their plants to create a homemade version of an evaporation humidifier.

Ultrasonic Humidifier?

Chances are, you are looking for a humidifier because you want the air in your environment to be wetter. We support that plan.
However, there is a point when humidity levels are too high, and you should not run your humidifier nonstop unless it has auto humidity detection.

Experts recommend keeping indoor humidity levels between 40% and 60% to avoid encouraging the growth of mildew and mold, so if your humidifier does not monitor levels for you, consider a humidity monitor for better indoor air quality.

Impeller Humidifier?

Impeller humidifiers work differently than both natural and evaporative humidifiers. An impeller uses a spinning disk and a diffuser.

The disk flings water droplets at the diffuser which further breaks them up into a fine mist that humidifies the air. These tend to be a bit noisier than the previously mentioned types of humidifier.
