Best Humidifier for Living Room
For most living rooms, the best home humidifier is the Levoit humidifier. The best humidifier for large room covers 430 to 753 square feet, and its 1.58-gallon (6-liter) tank runs up to 50 hours on low mist. Output reaches 300 mL/h of cool mist or 550 mL/h of warm mist, and the unit switches between the two, with auto mode turning the warm mist off to keep the noise down. Noise stays under 28 dB on low cool mist and under 40 dB on high warm mist.
Best Humidifier for Bedroom
The best humidifier for a bedroom is the Dreo 311S. The best humidifier for small bedroom is the Dreo humidifier, since it covers 300 square feet and its 4-liter tank runs up to 36 hours. Rated noise is 28 dB, the tank top-fills without coming off the base, and the mist is ultrafine at 5 micrometers.
The best humidifier for a bedroom that is easy to clean is the Carepod One, whose stainless-steel tank breaks into three pieces and goes in the dishwasher. It holds 4 liters, runs up to 30 hours over spaces up to 500 square feet, and has three ultrasonic mist settings and a built-in timer.
A child's room
Use a cool-mist humidifier rather than a warm-mist one, because a warm-mist unit can burn anyone who gets close. Place it several feet from the bed, about 2 meters, and run it to the 40-to-50-percent setting and then stop rather than leaving it on.
Either pick needs the same care: empty the tank, wipe every surface dry, and refill daily, then clean it every third day, scrubbing off scale, deposits, and film. Rinse the tank thoroughly after any cleaning or disinfecting agent, so the chemicals don't end up in the air. One room is the simple case; a whole house is a sizing problem instead.
Best Humidifier for Whole House
The best humidifier for a whole house is a central unit installed in the home's heating and air-conditioning system, not a portable. For an apartment or a living room, the best humidifier is a portable sized to the room. For the whole house, get the AprilAire 720M.
The AprilAire 720M is fan-powered and evaporative, rated at 21 gallons per day at high speed and 19 gallons per day at low speed, and sized for homes up to 6,250 square feet. It pulls heat directly from the furnace plenum.
Size a whole-house unit by volume, not floor area: the building's treated volume in cubic feet and how tightly it is built decide the capacity. At 8,000 cubic feet, a tight building calls for 3.3 gallons per day and a loose one for 10.0; at 56,000 cubic feet, 23.4 against 70.2. The best humidifier is the one sized to the space, not one model.
Which Brand of Humidifier Is Considered the Best
No brand is considered the best, because the room decides which unit you need. What humidifier is recommended comes down to the room: the best humidifier for a whole house is the AprilAire 720M, the best humidifier for a bedroom is the Dreo 311S, and a living room takes the Levoit LV600S. Match the unit to the room and the brand stops deciding anything.
Should I Put a Humidifier in My Living Room
Yes, when the air in the room is dry. A humidifier relieves a stuffy nose and helps break up mucus so you can cough it up, and it thins mucus so coughing and blowing your nose work better.
Dry air is what a humidifier is for. It irritates the nose and lungs and can aggravate a condition you already have, and it makes mouth breathing more likely; mouth breathing makes you snore and raises the odds of waking with a cough, a nosebleed, or a dry mouth. Keep indoor humidity between 30 and 50 percent.
The benefits of a humidifier in an air conditioned room are the same as in any dry room: the moisture is what helps. A humidifier for a room adds moisture and nothing else: an evaporative unit releases it invisibly through a wetted wick or filter, an ultrasonic one makes a cool mist with sound vibrations, and an impeller one throws a mist with a high-speed rotating disk.
Excess moisture encourages biological growth in a home, including dust mites and molds, so the top of the range matters as much as the bottom.
If water condenses on your windows, walls, or pictures
Relocate the humidifier, lower its humidity setting, or run it less, until the surfaces stay dry.
Which Type of Humidifier Is Most Effective
The evaporative type is the one to choose, because evaporative units disperse less, if any, of the pollutants a standing-water tank can grow than ultrasonic and impeller units do.
That gap is the whole argument: ultrasonic and impeller units can disperse microorganisms and minerals from their tanks into the room, and microorganisms grow readily in a humidifier that holds standing water. Breathing mist that carries them has been implicated in a type of lung inflammation. Warm-mist and steam units work by boiling water and releasing it as visible vapor.
If you run an ultrasonic or impeller unit anyway, fill it with low-mineral water such as distilled water. Minerals in tap water become white dust on your surfaces and crusty scale inside the unit, and scale is a breeding ground for microorganisms.
Best Humidifier for Allergies
When allergies are the reason you're buying, get the Honeywell HCM-350. The Honeywell is an evaporative unit. Adding moisture soothes irritation and reduces inflammation in the airways, so they are less reactive during asthma and allergy flare-ups. That counts for you more than for most buyers: the young, the elderly, and people with lung diseases or respiratory allergies are the ones most susceptible to airborne pollutants a humidifier puts out.
A UV bulb in the water path is claimed to render up to 99.9 percent of bacteria, mold, fungus, and virus in the water germ free.
The unit puts out 2 US gallons, or 7.6 liters, per day. A UV bulb sits in its water path, so the water that soaks the wicking filter is the water the bulb treats. That filter is soaked and replaced as part of cleaning, and the water tank and water tray are top-rack dishwasher safe, while the tank cap, filter, and main housing are not.
