Best home humidifier

Which home humidifier is best?

Home humidifiers are used to address a variety of needs. They can help soothe illnesses and allergies, alleviate the effects of a dry environment and can even help regulate temperature. Choosing the right humidifier for your needs can be complex, as any given model may not have the features you need.

One of the best home humidifiers is the Levoit Smart Classic 300S. It features a large range of options, including smart-home connectivity so you can easily control it from anywhere. 

What to know before you buy home humidifiers

Types of vaporization

Home humidifiers vaporize water using one of four methods: evaporation, ultrasonic vibration, steam and impelling mist.

  • Evaporation humidifiers are simple and successful. A wick gathers water and its vapor is dispersed with a fan. Many humidifiers use this method.
  • Ultrasonic vibration humidifiers are equally common. Soundwaves are sent coursing through the water, sending a layer of mist out of the machine. These models may not be suitable for homes needing high levels of humidity.
  • Steam humidifiers, also known as warm mist, are less common. They use a heat source to generate steam. More often you find this as an option in expensive humidifiers rather than steam-only models.
  • Impelling mist humidifiers cause water to be forced together at high velocities, sending the cascading droplets through the air. These tend to leave residues behind and are rarely found.

Filterless vs. filtered

Many home humidifiers are filterless. This saves you the recurring cost of replaceable filters and makes them easier to use. 

But be careful: filterless models allowed to run with old standing water or hard water can be hazardous to your health. Unused standing water will develop bacteria that will be expelled with the water when next switched on. And filterless models filled with hard water wll disperse the minerals inside into the air to gather as dust around your home, or worse, be inhaled. 

Avoid these situations and your filterless model will be safe.

What to look for in quality home humidifiers

Ease of maintenance

Humidifiers require maintenance, not just to continue operating, but to prevent health problems. Typically, this just involves a good cleaning every month or so. However, some models have odd configurations that make it difficult to scrub the areas that need scrubbing. Check the user reviews to see how easy a given humidifier is to clean.

Noise

Home humidifiers usually operate between 30-60 decibels, or the difference between a whisper and a standard conversation. Those with fans are usually the loudest. Some include noise dampeners such as “night mode,” which limits the decibels the humidifier generates.

Coverage

All humidifiers have a coverage range, which is the total size in square feet they can effectively add moisture to. Some are only suited to spaces as small as a kitchen pantry, while others are large enough to add moisture to an entire small home.

How much you can expect to spend on home humidifiers

Home humidifiers are available in three price tiers. Basic models for occasional, one-room use rarely exceed $30. Midrange models for regular use in average-size environments go up to $80. Beefy whole-home models can cost as much as $150.

Home humidifiers FAQ

What’s the difference between warm- and cool-mist humidifiers?

A. Each offers its own pros and cons, with some top-dollar models being able to do both. Warm-mist humidifiers are best used in cold environments, as their heating element usually raises the room’s temperature. The heating element also helps to kill bacteria, but can be hazardous to both children and animals and will draw more energy. Cool-mist models are safer to use and draw less energy. They tend to be louder, thanks to an internal fan and also are quicker to develop bacterial growth.

What percentage of humidity should my home be kept at?

A. That depends mostly on preference. Most homes have humidity ranges between 30%-60%, with humidities outside this range tending to cause health problems. Try setting your home humidifier to 45% humidity and adjust from there until you feel comfortable.
