Levoit LV600HH Hybrid Ultrasonic Humidifier

Best Overall Humidifier For Large Rooms

Product Overview

  • Coverage area: 753 sq. ft. / 70 sq. m.
  • Water tank capacity: 1.5 gallons / 6 litre
  • Warm Mist output: 500ml/hour
  • Cool mist output: 300ml/hour
  • Running time: 24 – 36 hours
  • Dimensions: 11.3’ x 7’ x 10.5’
  • Weight: 4.92 lbs

The Levoit LV600HH Hybrid Ultrasonic Humidifier is a dual mist humidifier that can put out both warm and cool mist depending on your settings. Covering an area of 753 sq. fr, this is an extremely powerful humidifier that can work well in a large room. Powered by ultrasonics, this humidifier does not have a fan and is whisper quiet. It registers a mere 35 dB when it is operating on the highest setting and it is barely discernible. This makes it a perfect choice for a humidifier in a bedroom or a study room.

In terms of functionality, this humidifier comes with an auto mode which does the heavy lifting for you by automatically adjusting the humidity to a comfortable level. However, if you would like to customize the humidity level yourself, you can also pick an exact percentage and adjust it at well until you find your preferred humidity level. This is made possible by an inbuilt humidistat that can accurately detect the level of humidity in the room. 

For homeowners who intend to use it overnight, you will love the timer that can be adjusted between 1-12 hours so it can shut off automatically during the night. However, if you are as forgetful as me in setting the timer, you will really appreciate the auto shutoff that kicks into place when there is no more water left in the tank. For my wife, she was really thrilled to find that this humidifier comes with an aroma box so she could go crazy with her essential oil aromatherapy. 

When judging the ease of use, I have mixed feelings about the Levoit LV600HH. The remote control is a nice feature which allows homeowners to adjust the settings from the comfort of their couch or bed in the middle of the night. 

However, I really have an issue with the water refilling. This is a bottom refilling humidifier and the water cap is on the base of the water tank. So during a refill, you have to remove the tank, turn it upside down to fill it up and all the while dripping water everywhere and then turn it back again before inserting it back to the humidifier. I suppose I am more of a top refilling kind of guy but that is just me.

As with most ultrasonic humidifiers, it is recommended that you use distilled water or filtered water instead of tap water. Tap water is considered hard water that contains traces of mineral deposits. When used in an ultrasonic humidifier, it releases white dust into the air which may be inhaled by the user. Also, hard water will cause rapid buildup of mineral deposits in the humidifier resulting in more frequent washes. And this is one heater which does require a fair bit of work when washing. There are multiple components which require cleaning and disinfection so each wash can take about 20 minutes if you are thorough. 

All in all, a nice sleek humidifier with numerous awesome features which does a great job in humidification. However, it does require a bit more work for maintenance.

Pros

  • Large coverage area
  • Dual mist function
  • Quiet – 35 dB
  • Long running time
  • Auto shutoff function
  • Aroma box for aromatherapy
  • Touchscreen LED display

Cons

  • Requires distilled or filtered water for best results
  • Refilling water is messy
  • Washing is somewhat tedious

What the fans love: “First, I love this humidifier. We have 4 different humidifiers in our home, and this one is by far our favorite. The settings are easily adjustable, no leaks, it’s stable, it’s quiet, no problems. And the customer service is great!”


Best Humidifier For Large Rooms Buyers’ Guide

Humidifiers can come in all shapes and sizes each with its own pros and cons and this can be confusing for the homeowner who is choosing a humidifier for the first time. When choosing the right humidifier for a large room, there are certain considerations that the homeowner should know in order to make the right choice. 

Types of Humidifiers

There are 4 main types of humidifiers

  • Evaporative
  • Ultrasonic
  • Vaporizer
  • Air washer

Evaporative Humidifier

In essence, evaporative humidifiers work by evaporation of the water in the humidifier and releases it as a cool mist. Inside most evaporative humidifiers is a wick that absorbs the water in the humidifier. A fan then evaporates the water in the wick giving us water vapor and increasing the humidity in the room. For those who are unfamiliar with what a wick is, it is a porous cylindrical structure that has a large surface area which allows maximum water absorption and water evaporation (my son thinks it looks like a beehive). 

Example of a wick filter used in humidifiers

The wick also acts like a filter to filter out any impurities or contaminants in the water being used in the humidifier. Due to the presence of this wick filter, the type of water used in an evaporative humidifier is less restrictive than an ultrasonic humidifier which does not use a filter. Generally, you can use normal tap water in an evaporative humidifier without any issues. Wicks are usually quite large in size and therefore you will find that most evaporative humidifiers are bulkier in size and also heavier.

Another advantage of evaporative humidifiers is that it can never over-humidify the air because it works by evaporation. If the ambient air is already saturated with water, evaporation will not be able to occur no matter how much the fan blows at the water. 

Example of an evaporative humidifier

The purchase cost of an evaporative humidifier is usually the lowest among the different types of humidifiers but the operating cost is the highest from the replacement of wicks and filters. It is recommended that filters be replaced every 3 to 6 monthly depending on the usage of your humidifiers. Different humidifiers may also have different recommendations so it would be best to check in with the manufacturers if you are intending to get an evaporative humidifier.

Evaporative humidifiers also tend to be louder due to the running fan that is used to evaporate the water in the humidifier. Some humidifiers can register noise level up to 50 dB at their highest speed settings. If you are intending to use your humidifier in your bedroom or if you are very sensitive to noise then an evaporative humidifier may not be for you.

Ultrasonic Humidifier 

An ultrasonic humidifier is a nebulizer that uses high frequency vibrations to break water down into ultra-fine droplets which then get released into the air as a mist. Depending on the specific model, the mist may be a cool mist or a warm mist. An easy way to see if a humidifier is an ultrasonic humidifier is to see if there is a mist plume coming out from the model. If there is a mist plume, it is usually an ultrasonic humidifier. 

An ultrasonic humidifier does not have a wick like an evaporative humidifier and typically does not have any filter as well. As such, they are usually less bulky and lighter. However, because of the lack of a filter to absorb impurities and contaminants, it is recommended to use either distilled water or filtered water in the humidifier. If hard water such as tap water is used, ultrasonic humidifiers may dispel white dust into the air due to the mineral contents in the water. 

Ultrasonic humidifiers have the highest humidity output among all the types of humidifier because it actively breaks down water into fine droplets and forcefully discharges it into the air. Theoretically, there is the risk of over-humidifying the air but most humidifiers have an inbuilt humidistat to prevent that from happening.

Example of an ultrasonic humidifier

Ultrasonic humidifiers do not use a fan in its operation and quietness is one of their main selling points. Ultrasonic humidifiers rarely register noise levels beyond 35 dB and are great for use in bedrooms, baby’s room and study rooms. However, after prolonged usage, ultrasonic humidifiers may shake a bit and hence make some noise. When that happens, it may be time to consider a change.

In terms of price, ultrasonic humidifiers usually cost more upfront but have the lowest operating cost because there is no need for filter replacement every 3 to 6 months. 

Vaporizer

Vaporizer humidifiers basically boil the water in the humidifier into steam before releasing it into the air. As you can probably imagine, the mist from a vaporizer can get quite hot and hence it is also known as a warm mist humidifier. Vaporizer or warm mist humidifiers are very popular among homeowners suffering from allergies or asthma because the warm mist usually has a more soothing and comforting effect on sensitive airways than cool mist humidifiers. 

Due to the heating of the water in the vaporizer, most bacteria in the water are also eliminated and the mist coming from these humidifiers are generally cleaner and healthier compared to an ultrasonic humidifier. 

Example of a vaporizer

For homeowners who are into aromatherapy, you will be glad to know that most warm mist humidifiers contain a medicine cup or reservoir  for the incorporation of essential oils into the mist. However, do not confuse  vaporizer/warm mist humidifier with a diffuser. A diffuser is an appliance that converts essential oils into tiny droplets of oil that are dispersed directly into the air. A humidifier can sometimes act as a diffuser but a diffuser can not humidify a room. 

Vaporizers/warm mist humidifiers generally do not have a fan and are also very quiet during its operation. However, homeowners will generally want to refrain from using these in a baby’s room or kid’s room due to the boiling water that is in these humidifiers. If they are accidentally knocked over and lands on the child, nasty burns are certain to happen. 

 Air Washer

Air washers are 2-in-1 appliances that combine a humidifier and an air purifier together in one unit. Besides being able to control the humidity in the air, air washers also clean the air by filtering large particles, pollen and contaminants from the air. With a combination of these two functions, the indoor air quality in your house will be maintained at a comfortable and healthy level. For homeowners who are suffering from chronic allergies and asthma, air washers may be your best bet yet.

Air washers work by using a series of spinning discs to filter out allergens and particles from the air as air is drawn into the unit. The discs then spin the water through a special filter that breaks it down into a fine mist that gets released into the air. For some models, the water vapor is created using evaporation before being released.

Example of an air washer

Depending on the models, air washers may contain fans and some do get quite noisy. Therefore, air washers do tend to be bulkier than normal humidifiers due to the discs in the unit. Because of the added feature of air purification, the upfront cost of an air washer is also the highest among all the other types of humidifiers.

Comparison Table Of Types Of Humidifiers

Size Of Room

When choosing a humidifier for a large room or for the whole house, it is crucial that you find out the size of your room or house as accurately as possible to avoid disappointment. The easiest way to find out the size of your room is to measure the length and breadth of your room and then multiply them together. To find out the size of the whole house, measure the area of each individual room and then add them together. For an odd-sized room, try to get an estimated measurement of the length and breadth before multiplying them. 

Once you have an idea of the actual size of your room, you can look at the models of humidifiers that you are interested in. Almost all manufacturers will list down the coverage area of their humidifiers in the product overview. These give you a good indication of what size room the humidifier is best for. 

When looking at these values provided by the manufacturers, I would probably round them down by about 20%. For example, the manufacturer may say that the humidifier can cover an area of 1000 sq. ft. but I would take away 20% from that and estimate the coverage area to be about 800 sq. ft. This is because these values were probably measured in an ideal environment where there are no leaks or drafts in the room. In real life, we may have leaky windows, wall cracks, door gaps that may contribute to the loss in humidity.

Ease Of Use

This refers to the user-friendliness of the unit. A humidifier that is user friendly should have the following features; intuitive controls, digital display and remote control. All these features add a touch of convenience to the overall experience and should be taken into consideration when choosing humidifiers.

Ease Of Maintenance

This refers to the ease of refilling water and the ease of cleaning. Most humidifiers will require a refill of water every 24 hour depending on the capacity of the water tank. For something that you have to do frequently, it makes sense to find a model that allows easy refilling that is fast, efficient and neat. Usually, a top refill model is easier to do refilling as you just need to cover the top lid and pour in water. Generally, bottom refills tend to be messier and more of a hassle.

Humidifiers usually need a good thorough wash once every week. Depending on the model of the humidifier, the cleaning may take anything from 10 minutes to 30 minutes. WHen choosing a humidifier that is easy to clean, avoid units with many components or units with many small parts that are difficult to access. Some models come with specialized brush to allow users to reach difficult to access areas. The water tank should have a large access hole which allows the users to place the whole hand in for easy scrubbing.

Timer

This is a useful feature if you intend to use the humidifier during sleep but not over the entire night. After a humidifier has sufficiently humidified your bedroom for the night after a few hours, you would not want to wake up just to turn it off. Therefore a timer that enables you to determine the duration of humidification will be extremely useful. 

Humidistat

Almost all modern humidifiers from reputable brands have an inbuilt humidistat. They allow users to determine a target humidity level and the humidifier will automatically shut off or start up as required to maintain that level.

Waterless Automatic Shut-Off

Having a model with automatic shut-off when the water runs out is a great safety feature in all humidifiers. This function detects when the water tank is dry and shuts off the unit. This saves electricity and also prevents overheating on the humidifier.

Noise

Noise from humidifiers is usually caused by the fan unit in the humidifier and they are usually found in evaporative units or air washer units. Ultrasonic and vaporizer units are usually quieter as they do not require a fan to generate the water vapor. 

Portability

Evaporative humidifiers and air washers are usually bulkier and heavier due to the extra components they have in their bodies and this reduces their portability. These units may be better suited for a fixed position in a house or room. Ultrasonic humidifiers and vaporizer are generally more compact and lighter and can be transported between rooms easily. 


Best Humidifier For Large Room Product review

Honeywell Cool Moisture Console Humidifier

Best Humidifier For Whole House

Product Overview

  • Coverage area: 1900 sq. ft. / 175 sq. m.
  • Water tank capacity: 3 gallons / 12 litre
  • Running time: 24 hours
  • Dimensions: 23.15” x 14.96” x 117.48”
  • Weight: 19.95 lbs
  • Warranty: 3 years

The Honeywell Cool Moisture Console Humidifier is a cool mist evaporative humidifier that has a coverage area of up to 1900 sq. ft. Perfect for a large living room or even as a multi-room option, this humidifier will not disappoint you when it comes to large spaces. 

Using evaporative technology, this humidifier utilizes a wicking filter to add moisture into dry indoor air before blowing it off into the room with a fan. With a wicking filter that removes impurities from the water, there is much less chances of white dust or contaminants being released into the ambient air as compared to an ultrasonic humidifier. Along this line, it is also less strict about the type of water that can be used because the filter can remove the impurities from normal tap water. It is not mandatory to use distilled water.

In terms of functionality, this humidifier comes equipped with an inbuilt adjustable humidistat that can automatically turn this humidifier on and off to maintain set humidity levels. With three speed settings, homeowners can personalize their preferred moisture output based on their humidity needs and noise level. Because it is an evaporative humidifier, there is no danger of over-humidification because the humidification is self-limiting once it reaches a certain level. 

Armed with 2 water tanks that can hold up to 3 gallons/12 litres of water, this humidifier can run up to 24 hours on the low setting. The water tank is designed with a wide tank opening allowing users easy access into the tank for thorough cleaning. It may look intimidating but once you get around to it, the parts are easy to disassemble and easy to clean. In terms of refilling water, this humidifier uses bottom loading so you will need to remove the tank while refilling which makes it a little troublesome. However, because it is a dual tank system, the humidifier can still run on a single tank while you are refilling the other tank. 

A Pro Tip for homeowners: Flip the filter over every time you refill the water containers. Doing so greatly reduces the buildup of crusty minerals on the filter and improves the longevity of your filter.

As with all evaporative humidifiers, this humidifier also utilizes a fan to blow the moisture into the air and this generates noise. On the low and medium setting, the noise level is not really noticeable but it does become somewhat noisy when you switch it up to the high setting. This might not be suitable in a quiet environment like a bedroom but should not be an issue in a large living room where there is conversation going on anyway.

Another issue to consider for homeowners would be the size and weight of this humidifier. Weighing almost 20 lbs, this humidifier is a heavyweight among the other models reviewed here. It simply boils down to how powerful it is and it is not surprising that it is bulkier than usual. However, if you are looking for something that can be transferred between rooms then this might not be a good choice.

All in all, a humidifier that is amazing for very large spaces. As with such powerful humidifiers, you will expect some noise. However, if you keep it in a place where noise is not an issue then this is perfect.

Pros

  • Extremely large area coverage
  • Easy to clean
  • Auto shutoff feature
  • Long running time
  • Able to refill water while operating

Cons

  • Noisy fan
  • Troublesome bottom refilling
  • Heavy and not portable

What the fans love: “A couple of months of use so far and I have to say, this thing rocks .This unit was on the low end of the cost scale and performs way beyond my expectations. We are humidifying over 2,600 sq ft easily!”


Elechomes SH8820 Ultrasonic Humidifier

Best Convenient Humidifier For Large Rooms

Product Overview

  • Coverage area: 430 – 755 sq. ft. / 40 – 70 sq. m.
  • Water tank capacity: 1.5 gallons / 5.5 litre
  • Warm Mist output: 600ml/hour
  • Cool mist output: 300ml/hour
  • Running time: 24 hours
  • Dimensions: 10.4” x 7.2” x 12”
  • Weight: 6.3 lbs

The Elechomes SH8820 Ultrasonic humidifier is a dual mist humidifier that is able to put out either cool or warm mist depending on the homeowner’s needs. Designed for large rooms, it comes equipped with a 5.5 gallon water tank that can run for up to 40 hours (on low settings) for areas up to 755 sq. ft. 

In terms of ease of use, this humidifier has a thumb up from me. Water can be refilled from the top so you just need to open the lid and pour water in. A lot more convenient compared to bottom refilling models. During water refilling, the water tank is also easily accessible and users will be able to put their whole hand in for thorough cleaning and scrubbing. However, this unit does contain many small parts which can be challenging to clean thoroughly. It also comes with a remote control so you can adjust it from the comfort of your couch or bed if you need to make changes in the middle of the night. 

In terms of functionality, there is the option for cool mist or warm mist depending on your preference making this a very flexible humidifier. A safety tip is to ensure the unit is out of reach of pets or children when using the warm mist function. There is an inbuilt humidistat that allows users to determine their preferred humidity between 30% to 80% in intervals of 5%. If you are an aromatherapy enthusiast, you will be glad to know there is a port for your essential oils as well. For the parents, this humidifier has a child lock that prevents your young children from meddling with the controls. 

A nice feature that is not commonly seen in other humidifiers is the 360 degree nozzle that allows the user to direct the mist where they want it. Another feature that is not commonly seen in ultrasonic humidifiers is the use of filters. This effectively reduces the white dust that usually comes with ultrasonic humidifiers. Of course, this also means you will need to replace the filter on a regular basis to achieve the cleaning effect.

 As an ultrasonic humidifier, quietness should be one of the main selling points of this unit. When using the whisper sleep mode, this model is advertised to only register 20 – 32 dB of noise. However, it is actually much closer to 40 dB on testing and may not be suitable for rooms where quietness is crucial. However, if you are very sensitive to light during sleep, you will be glad to know that this humidifier has a screen-off setting to eliminate all lights from the unit. 

Pros

  • Large area coverage
  • 360 deg nozzle to direct mist
  • Dual mist function
  • Has filter to reduce white dust
  • Child lock 
  • Easy water refilling with top refill

Cons

  • Has small parts that are difficult to clean
  • Noisy during operation, especially when using the warm mist function

What the fans love: “It works so well and very quickly! It easily humidifies my living room and the neighboring bedrooms and bathroom. It has a nice large water tank and immediately begins spouting out steam as soon as it is turned on. I love the two swivel heads on top which allows me to choose which direction I want the steam to blast.”


Everlasting Comfort Ultrasonic Humidifier

Best Budget Humidifier For Large Room

Product Overview

  • Coverage area: up to 500 sq. ft./ 47 sq. m
  • Water tank capacity: 1.6 gallons /6 litre
  • Mist output: 270ml/hour
  • Running time: 50 hours
  • Dimensions: 11” x 7” x 14”
  • Weight:4.25 lb

The Everlasting Comfort Ultrasonic humidifier is a cool mist humidifier that can cover rooms up to 500 sq. ft with its 6 gallons water tank. With a mist output rate of about 270ml/hr, this humidifier can last for 50 hours on the low setting. This makes it ideal for a large bedroom where you can leave the humidifier running through the night. As an ultrasonic humidifier, you can expect it to be quiet and it delivers on that. This humidifier is virtually silent during operation and is perfect for bedrooms or baby’s room.

In  terms of functionality, the water-less auto shut off feature enables the humidifier to turn itself on automatically when it runs out of water.The humidistat is controlled by an adjustable knob which allows the user to choose any humidity between their minimum and maximum. However, there is no numerical indication of the humidity level so you require a separate hygrometer to tell you exactly how humid/dry your home is.

For homeowners who use aromatherapy, there is an essential oil tray by the side so you can enjoy the benefits of aromatherapy with your visits. Unlike most other humidifier models, this humidifier is also filterless so you dont require costly filter changes. However, this does mean that there will be white dust coming out from the humidifier. 

In terms of ease of use, I am not a big fan. The water tank is easy enough to wash but the refilling can get pretty messy and wet because it is a bottom refilling humidifier. Most homeowners have complained that refilling can be difficult due to the shape of the tank and also how heavy it can get when it’s full.

All in all, this is a no-nonsense humidifier that will get the job done with no frills. It has a good price point even for users on a tight budget. 

Pros

  • Very quiet operation
  • Auto shut off 
  • Essential oils tray
  • Good price point

Cons

  • Refilling water can be difficult and messy

What the fans love: “It’s a great humidifier that does everything it was intended to do. The tank is huge! It is a nice perk since refilling a smaller tank every hour can get quite annoying. Even on Max power, which is a strong mist, this humidifier still lasts for hours.”


HuPro Premium Ultrasonic Cool and Warm Humidifier

Best Quiet Humidifier For Large Rooms

Product Overview

  • Coverage area: up to 500 sq. ft./ 47 sq. m
  • Water tank capacity: 1 gallons /4 litre
  • Running time: 30 hours
  • Dimensions: 14” x 11.2” x 10.5”
  • Weight: 8.48 lb

The HuPro Premium Ultrasonic Cool and Warm Humidifier is a dual mist humidifier that can cover an area up to 500 sq. ft. with its 4 gallon water tank. This large capacity humidifier has a running time of 30 hours between refills allowing users to use it through the night without waking up to refill it. If it does run out of water during the night, the auto shutoff feature kicks in, ensuring the safety of the unit and the user. As an ultrasonic humidifier, this model is also very quiet, registering only about 30 dB on the highest speed setting. This makes it an ideal choice for babies, seniors and sensitive sleepers.

In terms of functionality, the dual mist feature allows users to choose between cool or warm mist depending on their preference for the day. The smart humidification system incorporates three types of humidity control, auto mode, constant humidity and 5 speed levels. There is also an essential oils tray for homeowners who love to indulge in some aromatherapy at the end of a tiring day.

One particular feature that caught our attention was the triple purification unit that consisted of  a ceramic filter, UV light and air ionization. The ceramic filter contains active carbon and mineral pellets that will absorb impurities from the water as it passes through the filter resulting in cleaner and fresher air. The great thing about this filter is that it never needs replacement. Another feature that aids the cleansing of air is the air ionization. It produces 300 million cleansing negative ions per minute to decontaminate the water of fungus, virus and fungi. Combine that with an UV light that prevents odor in the water and you have a winner!

For ease of use, I really love that it is a top refilling humidifier because that is just so convenient for homeowners to refill without much effort and without any mess. The water tank also has an extra-wide opening for easy filling and cleaning. 

One gripe I have with this humidifier is that the mist shoots straight up and some droplets will just drop down and wet the surface the humidifier is sitting on. It would have been better if the mist can be directed away from the humidifier and further away. It still does a good job but users will need to make sure they protect the floor with a rug or a tray so that water does not collect. Besides wetting the floor, this also causes the humidistat to register a higher humidity than what the room really is.

Pros

  • Quiet
  • Auto shut off feature
  • Triple purification feature
  • Good coverage area
  • Easy to refill water and clean

Cons

  • Tends to wet the surface/floor that it sits on
  • Humidistat can be inaccurate because the mist is saturated near the unit

What the fans love: “Easy to clean due to the removable water bin. Virtually silent. No fans or other noise. Love the little warming tray to put some scented oil. Keeps the master bedroom humidity at 45% ( up from 33% naturally ) and has solved respiration problems due to dry air. Bought a second one for the office.”


Frequently Asked Questions (FAQs)

Q: Will a humidifier work in large room?

A: Yes. Humidifiers will work in a large room as long as you get a humidifier that is suited to the size of your room. Most manufacturers will specify in their product description the recommended room size for their humidifier. I personally would deduct 20% off that recommendation because their recommendation is likely based on ideal conditions without any leaks or drafts in the room. In a real life scenario, the coverage area is likely smaller than advertised.

Q: How big a humidifier do I need?

A: This depends on the size of your room. Measure the size of your room as accurately as you can before shopping for your humidifier. Once you know the size of your room, compare it against the recommendation coverage area as recommended by the manufacturers. I personally would deduct 20% off that recommendation because their recommendation is likely based on ideal conditions without any leaks or drafts in the room. In a real life scenario, the coverage area is likely smaller than advertised.

Q: Where is the best place to put a humidifier?

A: Long story short.

  • Placement in the middle of the room leads to fast and even humidification
  • Keep humidifier 14 -17 feet (4-5m) away from walls and furniture
  • Place 3 feet (1 m) away from the bed 
  • Elevate the humidifier 2 feet off the ground
  • Keep the windows and doors shut when using the humidifier
  • Avoid running a humidifier and air purifier in the same room
  • Avoid placing humidifier in direct sunlight
