Are you looking to make the air in your house healthier? Do you often get shocked by static electricity? Do you experience a runny nose and eyes? Are your lips, skin, and throat dry? Do you have allergy-like symptoms without allergens present? If yes, you need to buy a warm air humidifier.
A warm air humidifier fights against dry air indoors. During cold season, a humidifier can help keep you healthy and fight against colds. The National Institute of Health (NIH) recommends warm mist for colds and stuffy noses. To help find the best warm air humidifier to suit your needs, we have reviewed five of the top options to help you find your perfect match.
Top Warming & Misting Humidifiers On The Market
The Vicks Warm Mist Humidifier (V745) gets top marks because it is inexpensive and works very well. It is energy efficient and boils water quickly, removing 95% of bacteria from its mist.
It also has an automatic shut-off for safety when the water runs dry. The clear blue tank lets you easily see the water level. Because it is Vicks, there is a pocket to hold vapor-rub or another inhalant.
The Vicks Warm Mist Humidifier is a good choice for large rooms because it covers 500 square feet. It runs fairly quietly, although you will get an occasional gurgle as water moves around. Its filterless system is easy to clean, just check the unit monthly to see if there is build-up from your water source.
The unit holds one gallon of water and runs 12 hours on a fill. It has two output settings, low and high. This unit works best for a medium to large room.
Note: Honeywell makes an almost identical warm moisture humidifier, the Honeywell HWM705B Filter Free Warm Moisture Humidifier. This unit is black instead of blue, a bit quieter, and humidifies a smaller area. Other than that, the two units are interchangeable.

Only runs for 12 hours
Only 2 outputs
Must lift and turn over the tank for filling
The BONECO U330 Warm Mist Ultrasonic Humidifier is a better humidifier than the Vicks, but it also costs quite a bit more money. Thus, it comes in at #2 for value. The Swiss-made BONECO covers a larger area, at 650 feet.
The best thing about this humidifier is that you simply pour water in the top to fill it. This makes it much easier to operate than some other models. This unit does have a filter, which kills nearly 100% of germs, bacteria, mold, and mildew. It has extra safety features like a locked boiling chamber to avoid spills from kids and pets.
The BONECO has a humidistat that turns off when ideal humidity is reached (45-60%) and on again when you need more moisture in the air. Some people find this on-and-off to be annoying, especially at night when they are trying to sleep. Others complain that its built-in light is too bright at night.
The BONECO U330 comes with a filter and a calcium cleaner and descaler. This unit works for a large room, or a set of smaller rooms.

The Levoit Large Room Humidifier is your year-round system. It offers a hybrid system delivering both warm and cool mist. It covers 750 feet, the largest area we found.
It quietly humidifies a room very quickly and will shut itself off when it reaches your desired humidity. It comes with remote control and customizable or automatic humidity sensors. It also has a timer you can set in advance.
It is filterless but offers filters to deal with hard water issues. The maker recommends running filtered water in it or purchasing the filters. If you register it online, you get a 2-year warranty. This machine is in the upper area of the price range.
The Levoit is a small machine. The machine holds 1.5 gallons of water and will run for 36 hours on the lowest setting. This unit is best for people who want power out of their humidifier.

TaoTronics offers a stylish humidifier for those who want design. Whether black or white, this top fill humidifier is easy to fill with water and offers a pile of extras. It is a dual warm/cool model that offers a sleep mode where the warm mist is turned off, the machine quiets, and the lights dim.
The machine allows you to select your mist output, mist temperature, and humidity as well as offering a timer. It monitors your humidity automatically and its front display tells you how humid your air is. It will also shut off when out of water.
It has three mist levels, three mist strengths and two nozzles that provide 360-degree mist coverage. It is filter-free and even has a memory, allowing it to remember your last settings.
The price matches the options, as this is a more expensive machine. You cannot see the water level and it is difficult to access some small parts when changing the mineral pad and such. You will need to buy these pads if you do not use filtered water.
The TaoTronics Warm and Cool Mist Humidifier covers a 450 square foot area and runs 45 hours on a full tank at the lowest setting. This unit is best for people who want to look at a sleek box rather than a humidifier.

Difficult to place in room
The Crane USA Classic Warm and Cool Mist Humidifier is Ultrasonic. This means it creates a mist with high-frequency vibrations, operates near silently, and kills 99% of germs, bacteria, mold, and mildew. It also does not need to boil water, so it is safer around young children and pets. This model is offered at a mid-range cost.
This nice-looking unit has a tank with a 1.2-gallon capacity and operates for 55 hours on one fill. It covers 500 square feet and is good for a large room. It is filterless, but the maker does sell a filter for those people who have problems with hard water. The tank needs removed and filled at a sink, causing some risk of spills.
The Crane is one of the safest units around. Not only does it not have hot water inside, but if tipped over, a safety switch will shut it down. It will also turn itself off when it runs out of water. The plastic is BPA-free.
The Crane USA Classic Warm and Cool Mist Humidifier has multiple steam settings and creates both warm and cool mist. This unit is best for people with small children or pets.

What should my indoor humidity be?
The EPA recommends a humidity of 30-50%.
How do I clean this machine?
You should follow the manufacturer’s instructions, but most of these machines just need wiping down with a white vinegar and water mix.
Should I buy a filterless unit or one with a filter?
Filterless units are cheaper to run and easier to clean. A filter traps more dirt and germs, but it has to be cleaned and changed regularly.
What are the most important things to look for when buying a warm mist humidifier?
Run time on a tank of water is important. Think of how often you are ready to fill the tank. The tank design is also key. Do you have to remove it to fill it? Flip it upside down? Or can you simply pour water in the top? Also, look for the size of the unit and how much empty space you need around it and compare that to the space you have in your room.
The Vicks Warm Mist Humidifier-V745A is a great little machine at a great price. It works very well in most places for most needs. While it lacks the add-ons that the other units have (remote controls, sleep modes, or humidity sensors), it more than makes up for them in being able to quickly and easily humidify a room. This little workhorse is our top pick.
