Humidifiers help raise the humidity and moisture levels in your home. The problem is that most humidifiers are only designed for a single room, and often only smaller sized rooms. What if you have a larger space, or want to use the humidifier for multiple rooms?

This article will examine the best humidifiers for large rooms and multiple rooms, each reviewed and compared. We will also show you the consideration factors you need to make an informed decision and help you understand the various humidifier types and features.

Ideal Humidity Level in the Home

Having the right humidity in your home has a lot of benefits. For starters, it helps minimize mold and mildew, and it can reduce the condensation on windows and surfaces that lead to structural damage.

On a personal side, low humidity can dry your skin, cause chapped lips, and even nosebleeds. If the humidity is too high, you can develop respiratory problems, coughs, and sinus issues. According to the EPA, the ideal indoor humidity level should be below 60%, and ideally between 30 and 50%. This can be difficult to achieve based on all the factors, both internal and external, that come into play.

The only way to check the humidity is to use a hygrometer. These are relatively inexpensive tools that work much like a thermometer. Some humidifiers have a hygrometer built-in, which can help with automatic settings.

Choosing Humidifiers for Large Rooms

Humidifier Type Vs. Coverage Area

The type of humidifier will play a large part in the efficiency and power of the machine. There is more detailed coverage of the various types below the reviews. However, bigger humidifiers can cover more area and for longer times because of the size of their water tanks.

Ultrasonic humidifiers tend to be longer lasting than evaporative humidifiers, too. While there is still more research needed for the filtered vs. filterless models, filterless humidifiers seem to have higher output over longer periods, at least as large room capacity models are concerned.

Filtering Properties

Filters play a large roll in the efficiency of humidifiers. They help purify the water and the air that carries the vapor into the room. They type of filter will matter a great deal, too. HEPA quality filters can trap larger amounts of smaller particles. They do cost more and need more frequent replacement, though.

You also have the option of using a filter-free humidifier. These can also purify the air and water, but they don’t capture particles. If you go this route, make sure that the humidifier has some method of purification that goes beyond demineralizing the water.

Runtime & Water Tank Capacity

The runtime is essential because we expect the larger capacity humidifiers to run longer. Most of the time, you can expect at least a 24-hour runtime. This will depend greatly on the speed or mode settings on the machine and the tank capacity.

The larger the tank capacity, the longer the machine will run. Most large room or multi-room humidifiers will have water tanks that can hold between 1.5 and 4 gallons of water. When these models are set to the lowest setting, a single tank can last upwards of 50 to 60 hours, some even more.

Diffusion Functionality

Not to be confused with an essential oil diffuser, humidifier diffusion is something not every model or manufacturer deals with. Diffusion is when a waterproof membrane is used to soak up the water from the tank. The water is then vaporized or evaporated, where the vapor passes through the membrane.

This vapor, or mist, is what is pushed out into the room. With ultrasonic technologies and filter-free humidifiers becoming more prominent and less expensive, diffusion technology is going away. However, it is still available, highly efficient, and can lower the maintenance needed.

Noise Level

The noise level is defined by decibel ratings. The higher the rating, the louder the machine. For example, a hairdryer on high setting from 5 feet away will have a rating of about 65dB. This is fairly loud, as you are aware.

Ultrasonic humidifiers are the quietest of the bunch with a barely audible 22 to 30dB. Evaporative humidifiers are a bit louder but are more common among those that prefer white noise when they sleep. These models can get above 45dB but tend to stick in the high30s to low 40s range.

Ease of Use, Setup & Maintenance

One of the most commonly overlooked features is the ease of use. While it may sound simple, some machines are much more than just add water and turn on. Many humidifiers will have humidistats to control the power supply, speed, or timers based on the humidity levels.

Others may have different settings, modes, or functionalities that you may or may not need. Ensure you understand all of the features before you buy so you don’t overpay for things you won’t ever use.

The set up for all humidifiers is pretty simple. Some require a little bit of assembly, but overall once you open the box, you can place the tank on the machine, plug it in, add your water, and begin adjusting settings.

The cleaning and maintenance will need to be something you can handle too. Finding a humidifier needs weekly maintenance only to then realize you can’t fit your hand inside the tank to clean it properly can be a problem.

Extra Features

While simple machines are less expensive, they may not serve you as well. However, certain features can be invaluable (or a waste of your money) depending on your specific needs. You should check for features such as a built-in hygrometer or humidistat, built-in diffuser, timer feature, overflow protection, automatic settings, mist output controls, and essential oil diffusers.

Price & Warranty

Finally, the price and warranty will be a factor as well. Staying within budget is important, and you want to ensure you get good value for your money. Buying the most expensive unit just to have “the best” isn’t a wise choice, especially when that choice comes with items or features you don’t need or won’t use. Stick to the minimalist humidifier that serves your needs well, and you can save a bit of money while getting the best machine for you.

9 Best Humidifiers for Large Rooms Reviewed

1. AIRCARE Space-Saver

Best Evaporative Humidifier For Large Room
TypeEvaporative – Cool Mist
Room Coverage2300 square feet
Water Tank Capacity6 gallons
Runtime70 hours
Filter Change30 days

The best evaporative humidifier for large rooms is the AIRCARE space-saver 826000. There are a few models to choose from, but the 862000 is the best bang for your buck. With 2 fan speeds, easy operation, and simple controls, you can’t go wrong.

This cool mist evaporative humidifier uses a filter wick system to draw the water from the tank and to the fan. It produces a fine mist that can reach up to 2300 square feet, giving you plenty of space and time to add humidity and moisture to your home.

The simple controls consist of two analog dials. One turns the unit on and control fan speed while the other allows you to adjust the moisture level. Combined, you can fill the huge 6-gallon tank and let the machine run for up to 70 straight hours.

There isn’t much better when it comes to keeping your larger rooms or entire home at an optimal humidity. It lacks in the looks department, but with its compact design and plain white coloring, it won’t clash or stand out in any room.

You can also tuck it away in the corner of the largest room, or against the wall in a central part of the house for ideal reach. It is a bit noisy when on the high speed setting, reaching about 55dB, but it isn’t so loud that it would disturb you much. On low speed, it offers a gentle hum that many find pleasant to fall asleep to.

The 2-year limited warranty will actually cover the first wicking filter for 30 days. After that, the warranty only covers the machine. Replacement filters and cleaning solutions aren’t costly but are a constant purchase you need to make (about every month or two).

Pros

  • Simple top-fill water tank
  • Easy to use controls
  • Ideal for medium to large sized homes
  • Compact design and minimal aesthetics
  • Cool mist evaporation ideal for summer use

Cons

  • 2-year warranty is a bit light
  • Fan can get loud over time

2. OPOLAR Whole-house Evaporative Humidifier

Best Humidifier For Large Living Rooms
TypeEvaporative
Room Coverage1000 square feet
Water Tank Capacity2.6 gallons
Runtime20 hours
Filter Change30 days

If you want the best humidifier for large rooms, the OPOLAR evaporative model may be the one you are looking for. This unit is a lot larger than most other humidifiers, but it is easily portable and extremely reliable.

The touch screen digital display allows you to select the running mode, humidity level, and lighting. It is a relatively small display, though, and the touch sensors can be hard to get right on. Sometimes you will have to press a few times to get it to register.

This machine is fast, too. The fan and wicking filter material can go through up to 6 gallons per day, resulting in a rapid rise in the humidity levels of your large room. You can also monitor the humidity from across the room.

With a built-in hygrometer, the unit will display a colored LED on top of the machine to let you know when the levels are within range. A red light indicates levels are below 30%, blue is between 30 and 50%, and green is above 60% humidity.

It does only come with a 1-year warranty, but the entire machine is covered. Some reports state that customer service is challenging to get a hold of; however, the process is simple and quick after contact is made.

Pros

  • Illuminated humidity indicator
  • Timer function for all modes
  • Doesn’t produce a mist
  • Castor wheels for portability

Cons

  • 1-year warranty
  • Touch display can be challenging to activate

3. hOmeLabs

Best 4L Ultrasonic Humidifiers For Large Rooms
TypeUltrasonic – Cool Mist
Room Coverage215 square feet
Water Tank Capacity1 gallon
Runtime40 hours
Filter Change4 months

A compact yet powerful humidifier is brought to you by hOmeLabs. This quiet, ultrasonic humidifier is sleek, stylish, and fits in any room. It isn’t a whole-home humidifier, like a lot of others on this list, but it will be efficient in rooms up to 20×20 feet.

It has a touch panel display that blends into the case. The white LEDs are visible in any light, but won’t distract from anything. The water tank holds 1 gallon of water and has a low-level indicator.

You also get an essential oils tray so you can infuse your favorite fragrances with your mist to bring even more benefits to your environment. This model also makes use of a charcoal filter, which helps reduce odors and controls mineral deposits. The filter needs to be changed out 3 times per year (depending on use) and is fairly cheap.

On the lowest setting, this unit will run for up to 40 hours on a single fill. If you plan to use it while sleeping, you should still make sure there is plenty of water in the tank before you lay down.

It does come with auto shut off and burn out protection should the tank run dry, but it is always better not to let this happen. Cleaning and maintenance are simple, too. The machine comes apart quickly and has large pieces that are easy to clean. There are relatively few spots that are hard to access for cleaning.

Pros

  • Whisper-quiet operation
  • Easy to clean and maintain
  • Essential oil compatible
  • Auto shut off protection
  • touch-sensitive LED display

Cons

  • 2-year warranty
  • Not suitable for huge basements or multiple rooms

4. TTLIFE Ultrasonic Humidifier

Best Ultrasonic Humidifier For Large Rooms
TypeUltrasonic – Cool & Warm Mist
Room Coverage750 square feet
Water Tank Capacity1.5 gallons
Runtime40 Hours
Filter Change90 days

When it comes to ultrasonic humidifiers, you know you will get a quiet machine ideal for nurseries, bedrooms, and even the living room to watch TV. The TTLIFE model has a stylish design that fits almost any décor and will perform well enough that you won’t even know it is there.

This model also offers a touch screen display and a remote control so you can adjust settings from the bed or across the room. There are 3 levels to choose from, including the self-monitoring auto mode.

You also get the benefit of a built-in humidistat that will continuously monitor the humidity levels and adjust itself to maintain the settings you select. If you want to change these settings, you can do so with the touch panel on the front of the machine or the remote control from anywhere within 30 feet (line of sight).

One of the best features, though, is the ionic air purifier. This helps keep the air clean and fresh while also reducing minerals and deposits from the water. While it won’t completely remove that common white dust from tap water or a dirty filter, it is a marked difference.

The 1-year warranty is a little light for the industry, but TTLIFE offers the first 90-days to try the machine and return it for a full refund, no questions asked. After the 90 days, you have another 9 months of warranty time remaining to make a claim on anything that may go wrong.

Pros

  • Ionic purification
  • Capable of tap water use
  • Built-in humidistat for self-monitoring
  • Remote or touch screen controls

Cons

  • 1-year warranty (90 day return)
  • Must run on Fog Level 1 to reach full capacity

5. Proscenic 808C

Best Smart Humidifier For Large Rooms
TypeEvaporative – Cool & Warm Mist
Room Coverage750 square feet
Water Tank Capacity1 gallon
Runtime30 hours
Filter Change60 days

Proscenic’s 808C is a stylish, sleek, and powerful little humidifier that does a lot more than most other options. Not only does this model have cool and warm mist options for year-round use, but it also features a touch screen as well as voice and mobile app controls.

For a true smart humidifier, there isn’t much better.  The voice controls work with all Amazon devices and apps, or you can download the free mobile app and take full control over the device. With the mobile app, you can change the speed, mode, and even humidity settings. You are also able to turn the device on and off.

Aside from the multitude of controls, you can also choose to use cool mist or warm mist for your spray. Warm mist is generally better suited for wintertime as it helps maintain the level of humidity in the air and moisture in your skin. Cool mist in the summer can be refreshing and welcoming.

You also get the use of an aromatherapy tray for your favorite essential oils. This tray will allow you to use any oils to infuse a fragrance into the mist. However, larger rooms may not notice the oil’s effects as this machine can reach over 730 square feet.

The heating and cooling can be set to automatic as well, but there are some reports that this won’t work correctly all the time, as sometimes the heating will come on to promote the warm mist when you want a cool mist. Otherwise, for a humidifier that offers just about everything for large room capabilities, you can’t go wrong.

Pros

  • Wireless communications with Alexa devices and mobile app
  • Essential oil tray included
  • HEPA filtration for water and air
  • 7 speeds and adjustable modes

Cons

  • 1-year warranty
  • Automatic heating may come on when not wanted

6. LEVOIT LV600HH

Best Warm & Cool Mist Humidifier For Large Rooms
TypeUltrasonic – Cool & Warm Mist
Room Coverage732 square feet
Water Tank Capacity1.6 gallons
Runtime36 hours
Filter ChangeNo Filter

The Levoit LV600HH model is a filterless model designed for large rooms. It offers you plenty of safety features as well as control options. There isn’t a wireless node, but you do get a remote control.

The set up is as simple as it gets, and once you have everything programmed, you just turn it on and let it work. This machine isn’t the prettiest of the bunch, but it is a powerhouse. Providing moisture for over 730 square feet, it is commonly used in the middle of the house to help out in multiple bedrooms.

At high speed, the fan does get a little noisy. However, you probably won’t want the humidifier running at high speed when you are trying to sleep. To help it get through the night, lower speeds are preferred. It will cover the space regardless, and the lower hum of the fan and motor can help you sleep just as well as the air’s moisture.

If you need more help, it also comes with an essential oil tray so you can infuse your favorite fragrances into the mix. Like most large capacity humidifiers, the potency of the oils can be hit or miss. Some reports state the aroma is perfect, while others say they can’t smell it at all.

Aside from the noise, the only downside to this machine is the 1-year warranty. It is easy to make a claim should anything happen, but for this industry, 3 years or better would be ideal.

Pros

  • Warm and cool mist options
  • Acceptable for overnight use
  • Essential oil compatible
  • Remote control operation
  • Automatically adjusts for humidity levels

Cons

  • 1-year warranty is a bit low
  • Can get loud

7. Venta LW45

Best Filterless Humidifier For Large Rooms
TypeEvaporative
Room Coverage800 square feet
Water Tank Capacity3 gallons
Runtime24 hours
Filter ChangeNo Filter

Venta is another filter free humidifier that works in large spaces. Like the Levoit model, it’s isn’t a pretty machine to look at, and it may not win any awards for home décor of the year, but it produces humid mist to fill an entire home.

The 3 gallon water tank is simple to fill, and this machine not only purifies the water, but it also purifies the air passing through. You get two machines in one with a humidifier and air purifier. Covering 800 square feet, you can quickly raise the humidity to normal levels in multiple rooms at once, a large basement, or even a family room.

The Venta has  each sold separately) to allow you to use tap water with a water treatment additive, a cart to aid in portability, an aromatherapy tray, and a digital hygrometer to measure your humidity levels. Each of them is optional, of course, but they allow you to build the humidifier that suits you best.

With the water treatment, you can use plain tap water without voiding the impressive 10-year warranty. However, to maintain coverage, you must use the additive and increase your cleaning and maintenance schedule form every 7 to 10 days down to 4 to 6 days.

This link goes to sylvane.com which was linked to in the brief. It is the only place I could find the hygrometer for sale. The other 2 links here go to Amazon and if kept, will need affiliate link added.

Pros

  • 10-year warranty
  • Easy setup and use
  • Purifies water and air
  • Has additional parts for upgrades

Cons

  • Difficult to clean in some places
  • Case may become damaged after a while

8. Elechomes

Best Large Room Humidifier For Plants
TypeUltrasonic – Cool & Warm Mist
Room Coverage755 square feet
Water Tank Capacity1.4 gallons
Runtime40 hours
Filter Change30 days

If you have a lot of plants in your home, you know how easy it is for them to dry out. Overwatering can kill your plants even faster. The best option is to install a humidifier to keep the air moist so your plants don’t dry out.

The Elechomes humidifier also works to keep your skin from drying out and will keep your relative humidity where it needs to be. This touch and remote controlled unit is compact enough to sit on a table or counter, and strong enough to fill a 755 square foot room.

With a 1.45 gallon top-fill tank, you don’t need to worry about taking it apart every time it needs a refill. You only need to open the top and pour in the water. This top port opening is also the ideal method for cleaning.

When using the remote control you can change all settings and even power the unit on or off. However, unlike most infrared remotes with a range of about 30 feet, this one needs to be within about 6 feet to work properly.

It does come with an essential oil tray for your favorite fragrances and a sleep mode, which lowers the noise rating to below 30 decibels. The biggest downside though, is the nominal 18-month warranty. Claims can be made, but customer service isn’t the easiest to get ahold of.

Pros

  • Essential oil tray for fragrance additives
  • Sleep mode lowers noise level to 28dB
  • Compact design can be placed near plants
  • Dual nozzle output for maximum disbursement

Cons

  • 18-month warranty
  • Remote control needs to be close to machine

9. Hessaire MC61M

Best Evaporative Cooler
TypeEvaporative
Room Coverage1600 square feet
Water Tank Capacity14.6 gallons/Continuous flow option
RuntimeN/A
Filter Change6 months

While the Hjessaire MC61M is technically a swamp cooler, it works well to put a lot of moisture into the air. This beast is perfect for basements, garages, and patios during your outdoor summer barbecues.

The 68 pound machine holds over 14 and a half gallons of water with an adjustable float and louvers for ultimate control. However, there is also a continuous flow option if you would rather not mess with refilling. Simply attach your garden hose to the outlet, and the machine will run as long as you have it turned on.

The downside is that the filter here gets soaked, and to prevent damage, mold, or mildew, you need to run the machine longer than you want. At the end of the day or when you plan to store the unit, the cooler must be run in the fan-only mode for at least 30 minutes.

It also comes with a smaller 1-year warranty, which means you may only get a season or two of use before it expires. Still, if you need to keep your yard, patio, or garage cool for long periods, there isn’t anything better to use.

Pros

  • Ideal for outdoor use
  • Continuous water fill option
  • Simple toggle controls
  • Automatic oscillation

Cons

  • 1-year warranty
  • Must run for 30 minutes after use to dry filter

Types of Humidifiers Suitable for Larger Spaces

Overall there are two main types of humidifiers; ultrasonic and evaporative. There are also two methods of humidification which come in cool mist or warm mist options. Let’s take a closer look at these variations.

Ultrasonic

Ultrasonic humidifiers are the new guys on the block. Even though they have been around for years, their technology is still the newest. Essentially inside the machine area, there are two plates. These plates are vibrated at ultra-high rates.

When the water is drawn between the two plates, it, too, begins to vibrate, breaking up into tiny droplets. These droplets are then pushed into the room as a vapor to raise the humidity levels in your home.

Evaporative

Evaporative humidifiers use a couple of different methods to produce the vapor. The original versions use a filter material as a wick. The water is drawn up the filter and evaporates as the fan blows through it. The air absorbs the moisture and carries it into the room.

Impeller

Impeller humidifiers are the same as evaporative cool mist humidifiers. The moniker is just another name for the same thing. However, these units cannot heat the water and use a spinning plate to cool the water making a mist.

Warm Mist Vs. Cool Mist

As mentioned above, cool mist humidifiers work to cool the water and the vapor that is released. Used often enough, they can actually reduce the room’s overall temperature (though only slightly).

A warm mist humidifier doesn’t use a spinning disk. Instead, it has a warming plate that boils the water, turning it to steam. The steam is then carried out through the exhaust with the air to raise the humidity. It can also increase the temperature of the room slightly.

Humidifiers & Aromatherapy

Some humidifiers allow you to add fragrance to your mist. By utilizing essential oil trays or pads, you can infuse your room with various soothing aromas. In most cases, you will need a special model that has an essential oil option. A few, though, are capable of having the oils added directly to the water.

Some essential oils are known to help dry skin, dry eyes, and even sleeping habits. Oils such as lavender, peppermint, and eucalyptus can aid the humidifier in helping your skin maintain moisture. The main issue, though, is that larger rooms need more water in the humidifier, which needs to run longer to be effective.

In these cases, many essential oils burn off without being noticed, smelled, or felt. While it is a good selling point, if you are trying to use the humidifier in large rooms or multiple rooms, the oils may not be strong enough to make a difference.

The Best Placement For Humidifiers In Large Rooms

Large rooms are no different than smaller rooms when it comes to humidifier placement. You want to avoid placing them near electronics such as your television or stereo. You also want to keep them away from doors and windows.

When placement is in a special room like a nursery, you will want to make sure the unit is away from the crib and not pointing directly at the babies. You will also want to keep them off of the floor where they can become a trip hazard.

People Also Ask (FAQ)

Is it safe to leave a humidifier on all night?

It is safe to leave a humidifier on overnight while you sleep. However, there are a few precautions you need to make to ensure your safety as well as that of the machine. First, make sure the humidifier won’t tip or spill and that it has enough water to make it through the night. You also want to ensure that there isn’t a chance someone can trip over the machine or the power cord if they happen to walk past. Otherwise, the machines are durable and safe to use at all hours of the day or night.

Is a humidifier safe to use around children & pets?

Humidifiers are also safe around children and pets as long as the machine itself is out of reach. The mist won’t cause any harm. However, if you are using warm mist, the boiling pate can cause burns. Also, the use of essential oils can get into the eyes and lungs if the child or pet is allowed to breathe directly from the nozzle.

How big of a humidifier do I need for one room?

The humidifier needs to be large and powerful enough to disperse the mist throughout the room or rooms. Each model will tell you the maximum room size it is capable of adding humidity to. You need to know the square footage of the space you plan to use the humidifier in. To get this measurement, multiple the length (in feet) of the room by the room’s width. Compare this number to the maximum capabilities of the humidifier you plan to purchase.

Will a small humidifier work in a large room?

Depending on the room’s size and the humidifier’s capacity, a compact humidifier can work in a larger room. As long as the output capacity (measured in square feet) meets or exceeds the size of the room, there won’t be many issues. The smaller models may need to run longer and be refilled more often, but this should be the only concern.

Do humidifiers kill airborne viruses & mold?

Some humidifiers can kill viruses and mold. The humidity level itself is the largest combatant, not the humidifier. A relative indoor humidity of about 35 – 40% has shown the ability to kill mold and prevent it from growing. For viruses, you will need a humidifier that purifies the air as well as the water passing through. Check out our article on air purifiers and VOCs here.

How do I clean and take care of these devices?

All humidifiers will have specific maintenance details in their owner’s manuals. However, you can expect weekly cleanings, including removing the water tank, filters (if any), and scrubbing with a brush or sponge.

Is it safe to use tap water in a humidifier?

It is highly advised that you do not use tap water with a humidifier. Distilled water or demineralized water is recommended. The use of tap water can leave deposits, minerals, and aid in bacteria or mold growth.

Are humidifiers with permanent filters safe to use?

As long as the filter can be cleaned, permanent filters work just fine and are safe for long periods. However, some cheaper models use a permanent filter that cannot be cleaned, and the entire unit must be replaced when the filter goes bad. There are methods to prolong the life of a filter, including cleaning chemicals specially formulated for humidifiers. That, along with using only distilled water and preventing scale or deposits from building up, will also help.

Where is a good place to buy these units?

One of the best places to purchase humidifiers for large rooms is through Amazon. The 3rd party vendor offers many incentives to shop there, including expedited shipping, better customer service, and warranty claim processes and pricing. One of the biggest factors is that companies will also list previous year models at significantly reduced prices that you won’t find in stores due to new models taking up space.

Conclusion

Humidifiers for large rooms are not hard to find. The hard part is deciding which one is the perfect match for your space and needs. Whether you want remote control operation, essential oil infusion, or variable speed settings, you have a lot to wade through.

This article showcased the 9 best humidifiers for large spaces and also covered a buying guide to consideration factors to help you narrow your search. If you are still in doubt, take another look at the AIRCARE Space-Saver. This model is compact yet powerful with 2400 sq ft. capacity and simple to use controls.
