Most ultrasonic humidifiers are cool mist—and that’s fine for most folks. But what if the room you are trying to humidify is drafty?
In that case, a humidifier that can also pump out warm mist is a good solution. Now, the warm mist won’t heat the entire room—you’ll still need a heat source. But a warm mist humidifier can take a bit of chill off a drafty room.
We looked at several models and did some real world testing before deciding LEVOIT’s Humidifier For Large Room is the best of the bunch in this category.
First, it has a generous 6 liter tank capacity. And the brand has a good quality and reliability reputation, in our opinion.
Then you add a convenient remote that lets you change the settings from a distance—perfect for living rooms when you’d rather not leave that comfy couch.
What We Liked
• Quiet! Perfect for a home office, living room or kitchen.
• Display can be turned off at night. That’s great if you decide to use this humidifier in a bedroom.
• Essential oils tray.
• Auto shut-off.
• Humidity sensor to set comfort level.
• Works up to 735 square feet.
• 3 mist levels.
• Real world testing shows it works for about 12 hours before refilling. This can vary depending on the room size and dryness, however. The maker claims it can work up to 36 hours (on low) before a refill.
What Needs Work
• Humidistat could be more accurate. That’s true for most humidifiers we tested, however. It’s always good to have a separate humidity gauge to double check.
• Filters must be replaced periodically.
• Large footprint.
• White dust. This is true for many ultrasonic humidifiers, unfortunately—if you use tap water, the minerals in the water can precipitate out as white dust. The solution: use distilled water instead of tap.
• Warm mist humidifiers don’t last as long as cool mist models, in our opinion. Based on our research and testing, we believe this is caused by wear and tear on the heating element.
