Best Whole-House Humidifier: Buying Guide and Top 5

Humidifiers are wondrous appliances. When used correctly, they have the ability to improve the overall health and wellness of you and your pets by increasing the surrounding area’s relative humidity. They can also reduce the likelihood of contracting the flu, and they are able to ease asthma and cold symptoms. Due to the moisture they put out, humidifiers can lower static electricity and safeguard wood furniture.

What Happens When a Home Has a Low Relative Humidity?

In the winter, cold weather can cause some homes’ relative humidity levels to drop to the teens, which is well below the minimum recommended 25 percent. In turn, the people who live in these homes experience dry sinuses and general malaise. In some cases, houseplants may begin to wilt and expensive items like artwork and musical instruments can sustain permanent damage.

How Does Dry Indoor Air Occur?

When there is cold air outside, people tend to run their home’s heating system to maintain a livable temperature. However, water evaporates at a more rapid rate when the indoor temperature is warm. Although a heater can rectify cold temperatures, it simultaneously causes the home’s relative humidity to plummet, leading to dry air.

Can the Relative Humidity Be Too High?

Ideally, the air inside of any home should hover around 50 percent relative humidity. When the humidity rises above this percentage, bacteria and mold can grow and dust mites will thrive, negatively affecting your health and even destroying your home on a structural level. Therefore, it’s crucial to regularly monitor your home’s relative humidity.

What Types of Humidifiers Are Available?

For clarity, humidifiers can be broken down into five major categories. There are evaporator humidifiers that blow air over a wet filter. These humidifiers are budget-friendly, yet they are only suitable for one-room humidification. There are also cool-mist impeller humidifiers, which work similar to evaporators. Since impeller models don’t have a filter, it’s best to use distilled water in order to prevent mineral buildup.

Like their name suggests, steam humidifiers create steam by boiling water. Some models can be used in conjunction with vaporized medication for cold and flu relief. Alternatively, there are cool-mist humidifiers called ultrasonic humidifiers that utilize ultra-quiet high-frequency vibrations to generate mist.

Finally, there are whole-house humidifiers that hook up to an existing HVAC system to deliver humidified air throughout the entire home. As opposed to the other types, whole-house humidifiers require the expense and expertise of a professional installer.

What Is a Whole-House Humidifier?

The sole purpose of a whole-house humidifier is to raise the relative humidity of the home in which it’s installed. To get the water they need to function, some models glean it from the home’s plumbing system while others must be manually filled. Either way, these humidifiers push mist throughout the home’s ducts to deliver soothing moisture to every room.

Often, whole-house humidifiers are set up near the home’s water heater on in the basement. You can even get one with a humidistat, which adjusts the relative humidity by itself according to the percentage you program.

What Are the Different Kinds of Whole-House Humidifiers?

There are four major kinds of whole-house humidifiers you can buy. One type is a steam humidifier. This version heats water to a boiling temperature. Then, it takes the steam made by the water and shoots it into the home’s ducts. One downside to a whole-house steam humidifier is that it requires a ton of energy, driving up your power bill.

Another variety is called a bypass humidifier. This whole-house humidification machine utilizes the furnace’s heat to warm the water in its reservoir. As a result, mist forms and travels through the home’s vents.

There are also whole-house cool-mist options, such as a fan-powered humidifier that generates mist by blowing air across a panel of water. Unlike steam humidifiers, fan-powered models don’t need hot water to work, so they don’t dramatically impact your electricity bill.

Finally, there is the whole-house drum humidifier. Since it is easier and cheaper to install, drum humidifiers are a popular choice among homeowners. However, these machines use a belt-driven motor to evaporate the cold water; therefore, they require periodic belt replacements.

How Do Whole-House Humidifiers Compare to Portable Ones?

When looking at the benefits of whole-house and portable humidifiers, whole-house models have a leg up in certain areas. They usually don’t need as much maintenance as portable ones, and their filters tend to last for months without you having to clean or change them. Whole-house humidifiers also use fresh water so quickly that it doesn’t have time to become stagnant and grow dangerous organisms.

Whole-House Humidifier Buying Guide

A balanced indoor humidity level is crucial to your health. That’s why you need a whole-house humidifier that can deliver consistent, reliable results year round. To find one that won’t let you down, we created a detailed guide of the most common features available on top-of-the-line humidifiers, so you can find the best humidifier that fits your budget.

Whole House Humidifier Mist Levels

Virtually every high-quality humidifier has a setting that allows you to change how much mist the machine emits. If you don’t want to make those adjustments yourself, many models are equipped with a humidistat that can take care of that for you.

The amount of moisture the humidifier puts out depends on the chosen mist level. The bigger the space or the drier the air, the higher the setting needs to be. Higher levels produce more mist; however, it takes longer for a humidifier to run out of water when on a low-mist setting. Often, manufacturers list the humidifier’s mist delivery rate in the model’s specs.

Whole House Humidifier Mist Temperature

While cool-mist humidifiers are the most popular among consumers, some of these machines also offer a warm-mist mode. This feature is great to have when you’re under the weather and need relief from a stuffy nose or a scratchy throat. The time it takes for the humidifier to heat the water correlates with the capacity of its reservoir.

Whole House Humidifier Mist Nozzle

Pay close attention to the humidifier’s nozzle configuration. Some machines have one while others have two. The nozzle or nozzles may be stationary or movable. Dual-nozzle setups usually cover the most cubic feet of air, especially if you can rotate them 360 degrees. If you buy a humidifier with only one nozzle, make sure the outlet is wide.

Whole House Humidifier Tank Size

You’re a busy person. As such, you don’t have the time to constantly monitor how much water is left in your humidifier’s tank. To reduce the number of fill-ups, opt for a humidifier with at least a 5-liter reservoir. It also helps for the humidifier to have a viewing area that shows the tank’s water level or a timer you can set to turn the machine on or off automatically.

Whole House Humidifier Control Panel

The design of the control panels on humidifiers varies greatly from one model to the next. For instance, some have one push button that controls all the functions on the machine while others have a touch panel with a multitude of buttons. A lot of humidifiers also have an LED display that shows the settings you select. What you should choose is entirely up to your personal preference.

Whole House Humidifier Sound Output

Humidifiers are machines with moving parts; therefore, it’s impossible to find a completely noiseless one. If you are sensitive to loud sounds, your best bet is to get an ultrasonic humidifier. These humidifiers are quieter than other humidifiers such as fan-forced ones, and they never get louder than 40 decibels.

Whole House Humidifier Safety Features

Regardless of what appliance you buy, you want it to be safe to use, particularly if you have children or own pets. Most humidifier manufacturers integrate safety features into their products, like an auto-shutoff mechanism that activates when the tank runs out of water or becomes detached from the machine. Some even have a child lock that prevents little ones from pressing buttons.

Whole House Humidifier Essential Oils

Many people enjoy infusing the air around them with the scents created by essential oils. Although this is not a necessary feature to have, some humidifiers are built with aromatherapy in mind. To accommodate your essential oils, these humidifiers have a special drawer with a sponge that absorbs the oil, sending it to the mist-delivery system. In turn, the mist pushed out of the nozzle will smell like eucalyptus, lavender, sandalwood or whatever scent you’ve chosen.
