Ultrasonic for Bedrooms
The Levoit LV600S is the best ultrasonic humidifier I have used in a bedroom. The 6 liter tank lasts 36 hours on low and the auto humidistat shuts off at the target percentage. The mist is whisper quiet which matters when it sits two feet from your head. Use distilled water or the demineralization cartridge or you will get a fine film of white dust on every surface within a week.

I moved to Colorado and the indoor humidity dropped to 18 percent by December. My nose bled twice in one week and the hardwood floors started creaking. I bought five humidifiers over the next two months and figured out which ones actually work without making a new mess.

Ultrasonic for Bedrooms
The Levoit LV600S is the best ultrasonic humidifier I have used in a bedroom. The 6 liter tank lasts 36 hours on low and the auto humidistat shuts off at the target percentage. The mist is whisper quiet which matters when it sits two feet from your head. Use distilled water or the demineralization cartridge or you will get a fine film of white dust on every surface within a week.
Evaporative for Hard Water Areas
The Honeywell HCM 350 uses a wick filter and a fan, which means no white dust no matter what water you use. It is louder than an ultrasonic because of the fan, but the trade off is worth it if your tap water is mineral heavy. I run mine on medium overnight and the humidity climbs from 25 to 42 percent by morning in a 200 square foot bedroom.
Whole House Console Style
The AIRCARE MA1201 sits in a hallway or living room and humidifies up to 3600 square feet. It uses four large wick filters and a 3.5 gallon tank that lasts about 36 hours on low. It is bulky and not pretty, but for an open floor plan home in a dry climate, one of these replaces three bedroom units.
Warm Mist for Cold Symptoms
When my daughter got the flu, the Vicks V745A warm mist humidifier was the right choice. The heated reservoir kills most bacteria in the water before it leaves the unit. The mist is warm against the face, which feels better when you are congested. It uses more electricity than ultrasonic or evaporative, so I do not run it nightly when nobody is sick.
Furnace Mounted for Hands Off Whole Home
The Aprilaire 700 mounts to the forced air ducting and runs off your furnace blower. Once installed, you set a humidistat on the wall and never touch the unit again. Water comes from a small line tapped into the plumbing so there is no tank to refill. This is the answer if you live somewhere dry and want to never think about humidity again. Installation is one weekend with basic tools.
What matters most
What to consider
For one bedroom, Levoit or Honeywell. For an open floor plan, AIRCARE console. For sick kids, warm mist with caution around the cord. For a permanent solution, furnace mounted. Match capacity to room volume not just floor area because high ceilings double the work. Clean weekly with white vinegar to prevent mineral buildup and replace wick filters every two to three months in heavy use.
Frequently asked
Between 40 and 50 percent. Below 30 dries out sinuses and wood furniture. Above 60 invites mold and dust mites. A 10 dollar hygrometer pays for itself.
Hard water minerals get aerosolized along with the water. Use distilled water or buy a humidifier with a demineralization cartridge or a different technology like evaporative.
