Best Cool-Mist Humidifier Choice Without Exception: Levoit Ultrasonic Cool-Mist Humidifier
The humidifier has a small light on the front, but I don’t care for night lights when I sleep, so I turn the light off at night and sometimes turn it on during the day. (The kids love turning the light on all the time though). The nozzle on top turns around and can be put to any place you want the mist to come out. I think anyone buying this humidifier will not be disappointed.

This humidifier does wonders for colds and congestion. It’s easy to clean, and I use purified water so that there is no mineral build-up inside. It’s nice that the light turns off, since I like sleeping in the dark. I find it helps with my dry eyes problem, and with LASIK surgery I never want them dry. This is a wonderful help to little ones with colds and sniffles. I highly advise getting this one for its simplicity of operation and compactness.
Best Cool- and Warm-Mist Humidifier Choice Without Exception: Levoit Hybrid Ultrasonic Cool- and Warm-Mist Humidifier with Remote
I love the remote control that comes with this humidifier! It won’t wake the baby when I use it in his nursery and I can turn off the light. Eucalyptus essential oil can be put in the little box for when the baby has congestion. It’s made to be sturdy and quiet.
I just set the timer and it shuts down when the water is low or gone. Plus, I can set the humidity where I want it. Turning the nozzle on the top lets me aim the mist in the direction where I want it, which is awesome! This unit is highly recommended. It holds a lot of water so you can fill it up and let be for a while.

Humidifiers are systems for adding moisture to the air circulating inside houses and buildings. They provide water vapor or steam to increase the relative humidity.
If you are a mom or dad, you never want to see your baby or children be sick. It hurts us parents to see them hurting. When your doctor tells you to get a humidifier or you intuitively know the moisture will help baby’s congestion, stuffiness, croup, bronchitis, cough, and hopefully not the flu, then check out our reviews of the best humidifiers for babies.
Remember that a cool-mist humidifier is best. Warm or hot air increases the swelling in baby’s airways. Humidifiers are an environment for germs and bacteria ready to happen and multiply! Be mindful to wash it out with bleach and vinegar every day adding fresh new distilled or purified water for the baby. The little one does not need to breathe in minerals and lime scale from city tap water. And don’t use soft water; it uses salt to “soften” tap water.
Benefits of Using a Humidifier
The amount of water vapor in the air is known as humidity (moisture). You can see it outside on foggy days. Depending on the season and where you live, humidity will be higher during the summer. It will be lower during the cold wintertime. Home humidity should be between 30 and 60%. Problems can occur when humidity is too high or too low.
- Low Humidity irritates nasal passages, might cause dry skin, cause eyelids to itch, and makes the throat dry with a cough.
- High Humidity causes condensation on windows, makes your home feel stuffy and it is hard to breathe in high humidity feeling like a sauna. High humidity activates unsafe bacteria, mold, mildew, and dust mites. Allergies, asthma outbreaks, and other respiratory problems can be triggered by high humidity levels.
Additionally, with humidity too low, static electricity may become a problem causing irritating static cling of fabrics and the slight shocks you can get when touching doorknobs or metal. Furniture can crack and dry out, and papers can dry and crumble.
To be healthy you want the benefits of humidity at a level to provide comfort to avoid any health issues by having your humidity level too high.

Humidifier and Diffuser Differences—What to Choose
In cold weather climates, a humidifier will add beneficial moisture to inside air. A diffuser adds fragrant scents to the air using essential oils derived from plants and the mist is diffused into the air with moisture. Another device, the vaporizer adds medication to the moisture diffusing the medication with the mist when someone has a cold or illness. Each one has its own unique benefits.
Types of Humidifiers
Homes use small units for point-on moisture in one room. There are a number of types that are listed below:
- Central Humidifiers humidify the whole house and are built into heating and air conditioning systems. The newer wall thermostats allow you to select the percentage of humidity you want.
- Impeller Humidifiers use a rotating disk to produce a cool-mist.
- Ultrasonic Humidifiers use Ultrasonic vibration to produce a cool-mist.
- Evaporators use a fan to move air through a filter, wet wick, or belt.
- Steam Vaporizers create steam that cools before leaving the machine using electricity. Do not use this type of humidifier if children are around; the hot water inside it can cause burns, blisters, and scalding when spilled.
Ultrasonic Humidifiers use a metal diaphragm that vibrates at a high frequency to produce a cool or warm-mist. The sound vibrations push moisture into the air. The water molecules are micro-fine and the mist is absorbed into the air almost instantly. This humidifier type does not use a fan; therefore, it operates quietly not using filters.
Warm-Mist Humidifiers are the least expensive and they use boiled water for producing steam. Before being released into the air, the steam is slightly cooled. The warm-mist tabletop units will raise air temperature in a room and are quieter than evaporative humidifiers but cost more to operate. These units raise the air temperature that is nice for winter, but not so nice in warm areas. The heated water can cause accidental scalding. No one suffering from asthma should use a warm-mist humidifier because the warm-mist can irritate the airways.
Vaporizers boil water and releases steam moisture into the air. To reduce coughs and colds, stuffy sinus passages, medicated inhalants are sometimes added to be misted into the air. Being healthier to use than the cool-mist humidifiers, the steam is not as likely to disperse microorganisms or impurities in the holding tank water. More energy is required however, to boil water than other methods used. There are small single room vaporizers available that are used at bedtime or when a child or person is in bed feeling sick.
Cool-Mist Impeller Humidifiers use a spinning disk for delivering the water into a diffuser forming water droplets that float into the air. It can put dissolved minerals and microorganisms into the air. The dissolved minerals from tap water can appear as white dust on items in your home. Use distilled water to prevent this, which also adds to the cost of operating a cool-mist humidifier.
Evaporative Humidifiers use a fan for sending moisture out after having first soaked water up into a wick. This type is provided as large console types.
These small units are not expensive and the filtering system helps keep water minerals and microorganisms from entering the air. It is important to do timely maintenance on these units. The unit must be cleaned and replaced with new filters as recommended by the manufacturer. These are the most common in the marketplace, also known as wick or cool-mist humidifiers. The filters or wicks can become moldy when not thoroughly dried out between reservoir fillings. Over time, they also can have mineral deposits build up. When this happens, the filters need to be rinsed or replaced. If not done, the air cannot pass through the filter or wick and the unit stops humidifying. When you see the water at the same level in the reservoir, you will know the unit is not working.
The water in the unit evaporates based upon the relative humidity in the room. If a room has low humidity, the humidifier’s water will evaporate faster than a room that has high humidity. Consequently, this type of humidifier is self-regulating and as the humidity rises in a room, the water vapor goes down.
Whole-House Furnace Humidifiers - Winter not only brings cold, it also brings with it dry air. Retrofitting a humidifier to your existing furnace will do wonders for the lack of moisture in your home. Humidity extends the life of your wood floors, wood furniture, pianos, and art when a home is too dry. You will feel warmer when your home has humidity. You will not need to turn the heat higher with humidity to keep the house perfect. When you keep your home’s humidity between 30 and 60%, for health and keeping nosebleeds and mucous membranes moistened, you will be more comfortable. It is only wise to have additional humidity in your home’s air.
Which Humidifier is Right for You?
First, decide on whether you want to humidify your whole house or just one room, usually a bedroom. A small unit for your child’s room or a bedroom will usually be sufficient. When you live in a dry, arid climate, or have serious sinusitis, dry coughs, dry flaky skin, and dry hair, you might want to consider a whole-house furnace system.
- Be sure to purchase the right capacity and size for the specific room to humidify.
- Portable and tabletop humidifiers are great for one room. They can be purchased with two tank sizes for different room sizes.
- Whole-house humidifier systems are wonderful for adding moisture to an entire house using the furnace ductwork and are thermostatically controlled. A retrofit to an existing furnace is expensive. These units connect permanently to the water supply. No filling of water tanks is required. They are best installed by a heating and ventilation professional who will mathematically calculate the square footage of the house to be humidified to install the correct size system.
Top 9 Best Single Room Humidifiers
Best Cool-Mist Humidifier Reviews
1. Pure Enrichment Ultrasonic Cool-Mist Humidifier
The Pure Enrichment® model number PEHUMIDIF, is a premium ultrasonic humidifier emitting a cool mist and is whisper-quiet for sleeping all night thorough. This unit is a top best seller on Amazon.com® at an affordable price in white and light blue colors.
The unit humidifies the air in your room for a greatest run time of 16 hours continuously. After the water is gone it will shut off by design automatically. It has a soft blue night light that can be comforting to a sick child at night time. The light can be turned off when you push the power button 2 times. If you like, you can set the light to low or high without the light or with the light at low to high. It’s a personal preference for the function you prefer.
It is excellent to have and use for congestion, asthma, colds, flu, allergies, dry skin, and static electricity in the air—the door knob that zings you and the flyaway hair and clothes clinging to your body.
The misting nozzle at the top will turn 360-degrees so that you never need to move the unit to disperse the mist where you want it. Holding 0.4 gallons (50 ounces) (1.5 liters) of water in the reservoir will give you 250-square feet of coverage. This should encompass a large bedroom, living room, and baby’s room sufficiently distributing 5 ounces (150 mL) of mist each hour. That’s very good coverage using the low- or high-mist setting. It does have a beep sound and cannot be disabled.
The feet on the bottom will not slip or skid to hold the tank in place securely for safety and no water to clean up. No filters are installed or used with this humidifier.
For a healthy environment, it’s necessary to have moisture in the air to breathe in and to keep mucous membranes from becoming dry. Moisture ends a dry mouth and throat, dry eyes, dry skin and hair, sinusitis, and nasal congestion. Moisture is beneficial to infants, babies, youngsters, and all people and pets in your family, including healthier vibrant plants.
Use soft, distilled, or bottled water for best results rather than tap water. The minerals from hard water create a white dust when misting and the lime scale will clog up the inner workings and mister. The nozzle comes out and can be cleaned daily if you run the unit each day. Water must be changed each day as well to avoid mold growth.
Use the included brush for getting into corners and groves and clear distilled vinegar is the best for removing debris; add a few drops of bleach. Be sure to check the box carefully for the brush—it is there. Do not get water in the dry air exhaust hole. Do not put any of the plastic parts in the dishwasher even on the top rack.
Do not use essential oils, eucalyptus, additives, salt, or Vicks® VapoRub® in this unit. It will clog up the works and ruin the ultrasonic disc. If you want to use essential oils, buy a diffuser that also mists. It does not have a gauge to tell you the humidity. You might want to buy a humidity and temperature monitor or see the humidifiers here that have a 100% pure essential oil cup for adding essential oils to the mist: Levoit Ultrasonic Cool-Mist Humidifier and Levoit Hybrid Ultrasonic Cool- and Warm-Mist Humidifier with Remote control.

The gray console with 4 easy to roll casters is a great humidifier for an entire house up to 3600-square feet. AIRCARE® is made by ESSICKAIR®. The digital control provides extreme accuracy for maintaining an ideal level of humidity from 30% to 60% for health benefits, comfort, and to keep wood furniture and floors from cracking and drying out. It is an evaporative cool-mist humidifier with an output of 12-gallons. It disperses 3.9 gallons of water with the 4-speed fan to run it at low, medium, or high for an average run time of 36 hours. The tank holds 3.6 gallons of water. It has an adjustable humidistat.
The humidifier will automatically shut down when the humidity level is reached or when the water tank is empty. It has no pulley, belts, or wheels inside the unit to maintain. It is simple and easy to clean the mineral deposits from the wick. There will be no white dust or flecks with the filtering system. Simply remove the water tank located on the side. Check the filter indicator to see the status and roll to different rooms, as you need. If you have stubborn mineral build-up, use vinegar and water to remove.
One button turns the power off and on. Another button lets you set the humidity level and another button allows you to set the operation to automatic or manual. It runs quietly and you see an “F” when it’s time to refill the reservoir with water. For minimizing mineral deposits from hard water—calcium, lime, and scale—use a capful of S1708PDQ-U Humidifier Bacteriostat. It will be beneficial and save you some time. You can also purchase distilled water for about $1 a gallon at most stores.
The humidifier comes with a 6-foot power cord, and is UL listed. It will run on USA 110/120-Volts and the unit is ETL certified.
The unit is 20.5-inches high by 21.5-inches wide by 14.5-inches deep and weighs 13.5 pounds. The AIRCARE® MA1201 comes with a User’s Manual, a float, 4 casters, 1 wick (MAF1), and a 1-year Limited Warranty with 2-years Warranty on the motor.
3. Honeywell™ Cool Moisture Console Humidifier
The HCM-6009 evaporative cool-mist Honeywell™ QuietCare™ has 2 tanks for ideal performance. It was designed and engineered for multiple rooms for comfort in large areas. The humidity level with this unit will be 30% quieter than other brands. The dual tanks have a wide opening top making it easier to fill and clean. The humidifier uses one tank of water at a time.
The high output design has adjustable humidity controls with multiple output settings. It will run for up to 24 hours on one water filling. Humidity will keep your lips from chapping, hands from cracking and drying, and congestion will be gone from nose and sinus mucous membranes. You can run it 24/7, since it has an automatic shut off when out of water. Therefore, you will have no worries about it burning up if you are not “watching” it. It does not have a thermostat because there is no heat. The humidistat is built in and is controlled by the humidity level you set. When that level is reached, it will shut off.
Clean out the water tray about once a week that collects pet hairs and dust when it runs. Turn the filter over every 3 to 4 days to extend filter life. The 2 ProTec™ balls with silver will kill anything having bad smells. Put one in the hole of each water tank. When you do not use the unit daily, the stale water can smell and grow mold, mildew, and bacteria.
The water flows from the tanks into the water tray where it is absorbed by the ProTec™ treated filter. The adjustable humidistat turns the humidifier on and off automatically at the preset humidity settings done by you. There are 3 speed settings for adjusting the moisture level and sound intensity. The convenient “humidity reached” and “tank empty” will be helpful at a glance. The wicking filter will remove water impurities and reduce white dust and flecks from landing on your furniture. The ideal humidity level is between 30% and 60% for comfort and health. At 80%, your windows will drip moisture and mold will grow. The air blows out of the front and sides. Keep it 2-feet away from walls, since it must breathe.
The humidifier is manufactured in Southborough, Maine, and any repairs are done in Memphis, Tennessee. The Honeywell™ is made by the American company, Kaz, Inc., that manufacturers products under the brands of Honeywell™, Vicks®, Envirocare, and more.
It will run on USA 110/120-Volts, 50/50 Hz, UL listed, using a 240-Volt adapter for those outside the USA.
The dimensions are 23.2 by 15 by 17.5-inches and weighs 20 pounds. The Honeywell™ comes with a User’s Manual, filter, and a 3-year Limited Warranty.
Things to Keep in Mind when Choosing the Right Humidifier
The right humidifier for you depends on where you are going to use it and what you want to accomplish with it. Do you live in a dry climate and need humidity? Do you occasionally have sick children that will benefit from humidity? Do you have health problems from the lack of humidity? Do you have annoying static electricity and dust in your home?
You will want to keep in mind several things: performance, features, design, service, and warranties.
Performance—Most humidifiers express the output of humidity in gallons of water used in a 24-hour period. They are also evaluated by how many square feet will be humidified. You will need to buy a humidifier for the correct space of your room or house. When your air is too humid, over 60%, the conditions are right for growing mold, mildew, and bacteria.
Features—Ultrasonic humidifiers provide both warm and cool output. This type unit uses cold water that is passed over a heating element to become warm. When the water is warm, a mist leaves the Ultrasonic unit at a safe 104 degrees Fahrenheit. The water inside the unit could burn a child if it is tipped over. Evaporative warm-mist humidifiers heat the water to boiling. It is safer to use cool-mist humidifiers around young children, infants and the elderly.
Hygrostats and/or humidistats that measure the humidity in the air are provided on the best humidifiers. These help you to know the moisture level you want without guessing what the output is.
Design—If you know where you want to put the humidifier, measure the unit to see if it will fit your space. Your humidifier of choice should be easy to carry to the sink for water refilling. It would need to have handles for gripping when it is wet.
Service and Warranties—Most humidifiers typically come with a 1-year warranty. Purchase from a company that backs their products for a longer time. Be sure the company provides a toll-free number or live chat for support. You will want to select a reputable company providing customer support assistance.
How to Choose the Right Humidifier for Your Home
Humidifiers benefit the comfort level of your home. The right choice will satisfy all of your needs. They are not expensive and easy to use. Here are some specific guidelines for choosing your perfect humidifier:
Square Footage—It would be overkill to retrofit a humidifier to an existing furnace if all you need is a humidifier in one room occasionally. A smaller portable humidifier will easily provide the comfort level you need and save you money. To figure square footage multiply the width by the length of the room. If a room is 12 W x 10 L it will be measure 120 square feet.
Running costs—Whole house furnace humidifiers are more expensive to initially install but cost the least over the years. Warm-mist vaporizers are cheap to buy but are the worst energy hogs. This is because the water must be evaporated by first boiling it. Unnecessary usage can be better controlled when using a humidistat for running time. Replacement filters, wicks, or cartridges are another cost to consider. The replacement cost can make this unit not cost-effective.
Humidistat—is an important dial or digital device and might include a hygrometer for detecting moisture, to display the humidity level and to shut the humidifier off. Humidistats are important since a unit without a gauge will continue to put mist into the air until it is manually shut down. Since humidistats are not very accurate allowing condensation to form on windows, and create mold and mildew, it is best to have a portable hygrometer.
Noise—the warm-mist tabletop humidifier barely makes any noise except for a slight boiling and hissing. Evaporative humidifiers create as much noise as a small window air conditioner or as much as a vacuum cleaner. The larger evaporative console models are used for larger areas; they will be best placed away from sleeping areas because of their noise.
Water Quality—when hard water from the faucet is used, many humidifiers will have a lower output of mist. They usually require more costly maintenance. Distilled water might be worth it, but that is an additional cost as well.
Safety—purchase a humidifier that automatically turns off when the reservoir is empty. There are models that will beep when the water is low and needs refilling. A reservoir that is transparent will show you when water is needed.
Warm or Cool—some people prefer cool-mist feeling that warm-mist is the same as breathing inside a sauna. Others like the soothing warmth of the warm-mist saying it makes the air feel soft. It is a personal choice and your doctor can recommend which one is best for a medical problem. If you use a vapor medication, such as Vicks®, the moist warm-mist vaporizers are the way to go.
Humidifiers - Frequently Asked Questions
Humidifiers are essential during the cold winter months, in dry climates, or yearlong. Humidity in the air makes the air warmer and more comfortable—that ‘chill’ will be gone. It is easier to breathe and humidifiers add that much needed moisture to your living environment. Do not be confused with de-humidifiers—they remove moisture from the air.
Be sure to keep the box your humidifier came in to store it when it is not in use. Date the box so you will know when you received it. Be sure to keep the User’s Manual and any other instructions or papers in a place you can quickly find. You could put them all together in a plastic bag with the sales receipt in a handy spot.
By using a humidifier, you will improve dry cracked skin, nosebleeds, congestion, and sinus problems. To be enlightened about what to know when purchasing a humidifier—what type, how they operate, how to clean, and what to expect—we have listed frequently asked questions for your knowledge.
There are not too many differences. A cool mist humidifier makes breathing easier for allergy, asthma, and respiratory problems. If you breathe easier in a steam-filled bathroom or when the humidity is high when it is raining, a warm mist would be better. If it were harder to breathe with lots of humidity, a cool-mist would be better. The warm mist uses a heating element to boil water for a steamy vapor where a cool mist unit does not. A warm-mist might not be the best consideration with young children and pets since it has a heating element. The cool mist disperses its mist at room temperature.
Yes, humidifiers run 24/7 to keep the moisture at a perfect level in your home.
There are humidifiers in the marketplace that have built-in features to either reduce or prevent bacteria from growing in the water tank and at that the output device emitting the moisture. Some humidifiers use Nano or silver eon technology and are more expensive. You will still have to clean, demineralize (hard water), and disinfect the unit to keep the growth at a minimum. Even though these units cost more, they are well worth it and lengthen the life of the humidifier. You will probably only find Nano-silver technology in the specifications rather than in the unit’s description.
No. Do not add salt to a humidifier. Salt is corrosive and it will ruin metal pieces, seals, filters, and decrease the life of the humidifier. You can corrode the heating element in a warm mist unit. It can be a fire danger from overheating. Water with salt in it boils at a higher temperature. The circuit breaker can trip or a fuse can blow. You will void your warranty doing so.
Measure your bedroom or other rooms you want to humidify. Measure the length by the width (feet), and multiply for square feet: A 10×12 room = 120-square feet. A 15×15 room = 240-square feet. A 700- to 900-square foot size unit would do well. Manufacturers vary in terms of square feet. By using the highest output on your humidifier, you will have the best running operation for your room.
You will probably need to refill the water tank after about 12 to 16 hours of operation contingent upon if you run it 24/7 and on high or low. You will typically refill the water reservoir each morning or evening. Do not go to sleep with the unit low on water; make sure it is full up for sleeping.
Some humidifiers create a mist that is invisible and you might have this type. If your humidifier is running and the water level is going down, then the unit is taking in air, and it should put out a mist that is invisible. Check your Owner’s Manual to verify your unit’s operation manner.
Be sure to read your User’s Manual. It should be cleaned on a regular basis to stop mildew, mold, fungus, and bacteria from growing. Never let the water sit in your humidifier because standing water will grow pathogens. A good rule of thumb is to empty the water daily. Maintaining that practice means you can thoroughly clean and disinfect every week or so, rather than daily. That is easy and quick to do so that you do not inhale contaminated mist. Follow the manufacturer’s instructions for doing this procedure. You will want to remove mineral deposits if you use hard water. Distilled water is always best to use to keep your humidifier in great shape.
Yes. However, many of the new humidifiers have built-in programmable timers digitally controlled. This lets you run it when needed saving you energy as well. Humidifiers with a countdown timer lets you program it when it is currently operating to shut off. If you do not have this type of unit, you can use a timer set at the number of hours to run safely.
It is hard to tell how much energy a humidity will use. It is not expensive to run a humidifier, so check your electric statement.
- Cool-mist humidifiers have the ability to moisturize larger areas and use less energy than the warm mist units.
- Warm mist humidifiers heat the water so will use a little more electricity that the cool mist units. They release a warm invisible mist into your room.
- Larger tabletop units use less energy than console humidifiers running all day.
- Whole-house humidifiers attached to your furnace’s ductwork use the least amount of power and are the most efficient.
Ultrasonic humidifiers have less noise because they produce ultrasonic sound waves. Ultrasonic sound is above the frequencies we hear, so these units are quiet. Evaporative units use built-in fans to emit the mist and will have the loudest sound because of the moving parts. Warm mist humidifiers do not use a fan so are less loud than cool mist. You will become used to the sound as a white background noise and with a television or music on, you will not hear it.
White dust is a result of minerals naturally found in hard water. It is not harmful, is as easy to clean as you would clean any dust. It is sometimes released into the air from humidifiers. Warm moisture steam humidifiers and evaporative cool misting humidifiers do not release white flecks and dust. Ultrasonic humidifiers can release dust if they do not have a demineralization cartridge to trap minerals before they enter the misted air. Use distilled water if white dust is a concern. Distilled water will not make white dust, you will not have to remove mineral deposits from your unit, your filter will last longer, and you will not need to clean it as frequently. You still have to change the water every few days and disinfect pursuant to the manufacturer’s instructions.
Be sure to check your User’s Manual, since different brands and humidifier types have different requirements. If you do not own a humidifier and are planning to purchase one, buy one that has a mineral cartridge. Hard water from the tap or well has minerals that can collect inside the unit. The mist might contain white flecks and dust around the humidifier area caused by minerals. When you inhale white dust over time, it can exacerbate respiratory conditions or trigger new problems. The cartridges in units with one attract and take in the minerals from hard water for less of a chance to breathe the white dust in. If your existing unit does not have a mineral cartridge, it is best to use distilled water that has no minerals.
If you use CPAP (Continuous Positive Airway Pressure) therapy, this machine helps a person who has obstructive sleep apnea (OSA) breathe more easily during sleep. A full-face mask should not change the water amount used in your unit at night or any other time. If you have air leaks around your mouth, you will lose air and moisture via your mouth. Warm humidity will not wear out your masks and hoses. The tubing included with the unit can withstand much higher temperatures than the slight heat produced by the humidifier.
Humidifiers of any type put large amounts of moisture (humidity) into a larger area of space and can operate for longer periods. Humidifiers are made of sturdy metal or thick plastic and are large in size and use great amounts of water.
Diffusers, however, are small glass, plastic, or ceramic devices about the size of an apple up to the size of a 5-pound bag of sugar. It would take 6 to 10, 5-pound bags of sugar to equal a small room humidifier’s size for dispersing humidity when a child is sick.
A personal diffuser can fit into a purse or satchel when traveling because they are so small, and some of the larger ones can sit on top of a table in a more limited to a small area. A diffuser can be a very small humidifier emitting a mist only from water. They are primarily used as aromatherapy essential oil diffusers for misting a lovely fragrance into the air having therapeutic benefits for colds, sore throats, dry coughs, dry flaky skin, sinus irritation, and dry mucous membranes in the nose. They also help those suffering from hay fever, allergies, asthma, and respiratory problems. The diffusers use the components of nature’s plants that are known to have healing powers.
Some people have no need for the moist (humidity) essential oil’s benefits, so they use the fragrance from the diffuser to make their home’s specific rooms, office, spa, or hair salon smell wonderful all day. Some boutiques use diffusers with lavender oil to have their shop smell great when customers drop in.
There you have it. Bulky humidifiers are for sizeable areas and diffusers are for local small area spaces. Humidifiers can operate longer with larger amounts of water consumed, and diffusers operate for shorter periods needing to be refilled with water more often. Some of the latest more advanced diffusers can run up to 15 hours without a refill and that is because the small units have larger reservoirs for holding water. They will typically cover 200- to 1000-square feet.
Both humidifiers and diffusers produce moist vapors into the air. One is simply bigger than the other is.
