  • Essential Oils Compatibility: No
  • Refilling: top fill

The TaoTronics TT-AH018 warm and cool mist humidifier is an ultrasonics humidifier that can produce both warm and cool water vapor to humidify the room. While not technically a steam vaporizer, it does contain a heating element to produce warm mist that can reach temperatures of 60°C / 140°F. As an ultrasonic humidifier, there is no fan required and hence this unit is pretty quiet. It registers about 35 dB while it is operating and is a good fit for a bedroom or study room where you might be keeping your plants.

With a coverage of about 200 to 450 sq. ft., this humidifier is good for a medium sized grow room and can run up to 45 hours between refills. For refilling, this is a top fill humidifier and refilling is easy and convenient. Just pull up the top lid and pour water in. 

Other features include a touch screen LED display for style and easy handling. The settings may be adjusted to customize mist output, mist temperature and also the humidity level. As with any good humidifier, this model comes with an inbuilt humidistat that allows it to determine the room humidity and adjust the humidity according to the plant’s needs There are also two 360° nozzles which enable the user to direct the mist towards the parts of the plant which needs more moisture.

As with most ultrasonic humidifiers, there will be white dust generated from this unit because of the mineral contents in the water. As much possible, it is advised to use distilled or filtered water rather than hard water. That might be a little bit more troublesome for users but if you do not mind cleaning the humidifier slightly more frequently, hard water is fine as well!

Pros

  • Has warm and cool mist for different seasons
  • Able to customize mist temperature to suit one’s needs
  • Quiet during operation

Highly recommend this humidifier. “


Best Humidifier For Indoor Plants 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 a humidifier for your houseplants, there are certain features which are more crucial and we will highlight them in our buyer’s guide below.

Are Humidifiers Good For Plants?

The short answer is yes. The more elaborate answer is it depends on the humidity levels in your home and the moisture requirements of your plants. 

Most homes and climates are too dry too for plants to grow well and plants become dry and withered up. Most plants thrive well in humidity levels between 40% to 60% so it is best to keep your homes within this range. However, this can be difficult to achieve during the winter seasons and a humidifier is required. Granted that most plants also have less needs for moisture during the winter season, the amount of moisture in the air is still insufficient to sustain the plants.

Depending on the moisture requirements of your plants, it can also impact if you need a humidifier. If you have plants that are very “thirsty” like orchids or plants with large broad leaves that lose a lot of water through transpiration then you really need to maintain the humidity levels well. However, if you are more of a succulent kind of person, then you can totally give the humidifier a miss! 

Types Of Humidifiers

There are 4 main types of humidifiers

  • Evaporative
  • Ultrasonics
  • Steam Vaporizer
  • Air washer

Evaporative

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 vapour 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.

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. 

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.

A evaporative humidifier is a great choice for humidifying your plants as it can put out a good amount of cool mist without any danger of over-humidifying the room air. 

Steam Humidifiers/Vaporizer/Warm Mist

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. 

These vaporizer types of humidifiers may not be most suitable for houseplants as the temperature of the warm mist can get quite hot in some models. The increased temperatures will not be conducive for your plants and may cause injury to them. 

Ultrasonics 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.

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. 

An ultrasonic humidifier is also a suitable choice in homes with plants as it can usually put out both cool and warm mist. There is less maintenance as users do not have to change filters regularly but usage of distilled/filtered water is preferred to reduce generation of white dust.

 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.

The upfront cost of these air washers are usually much higher. Therefore if you are just using your humidifiers mainly for your plants, there is no need for air purification and these air washers may be an overkill.

how to choose humidifier

Size Of Room

When choosing your plant humidifier, you need to find out the size of your room 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.

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.

Humidistat

Almost all modern humidifiers 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. This is quite important if your plants have specific humidity levels in which they thrive.

Most plants will do well with humidity levels between 40% to 60% which is also the most optimum level for us as well. However some plants do better in drier conditions. Ferns do best between 40% to 50% while orchids prefer a wetter environment between 50% to 60% relative humidity.  For some tropical plants, you might even need humidity levels above 80%!!

For the serious house plant grower, maintenance of the ideal humidity level can also be achieved if there is an inbuilt humidistat

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..

Portability

For homeowners with multiple plants in multiple rooms, it can make a lot of difference to your quality of life if you get a unit that is light and portable. Imagine having to lug a heavy humidifier multiple times a day! If you value portability, choose models that are lighter with a small water tank. A large water tank that is filled is not easy to carry. An added bonus is if they come with carrying handles.

Adjustable Nozzle

Having a 360 degree rotatable nozzle ensures that the mist can be pointed towards the parts of the plants that need it the most. Some parts of your plant may be in more dire need for moisture and having this ability to direct the nozzle there really helps. The alternative is to place your humidifier right below the area but sometimes this may not be possible and the mist does not go where you want it to go.

This is also great when you want to direct the mist AWAY from certain areas such as your furniture or plants that prefer a drier environment.


Best Humidifier For Indoor Plants Product review

Levoit LV600HH Hybrid Ultrasonic Humidifier

Best Large Room Humidifier For Houseplants

Product Overview

  • Coverage area: 753 sq. ft. / 70 sq. m.
  • Water tank capacity: 1.5 gallons / 6 litre
  • Essential Oil Compatibility: Yes
  • 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 grow 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 where you might be keeping your houseplants.

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 until you find your preferred humidity level. This is great for plants which may require a higher or lower humidity than usual and having this adjustable feature gives you tons of flexibility and gives you more options when deciding what plants to get.

For homeowners who sometimes forget to do a refill, you will really appreciate the auto shutoff that kicks into place when there is no more water left in the tank. For users who use aromatherapy, you will be thrilled to know there is an aroma box for your essential oils in this humidifier.

Regarding 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. 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.

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!”


Homasy 4.5L Cool Mist Humidifier

Best Medium Room Humidifier For Houseplants

Product Overview

  • Coverage area: 380 sq. ft. / 35 sq. m.
  • Water tank capacity: 1.2 gallons / 4.5 litre
  • Refilling: Top fill
  • Running time: 30 hours
  • Dimensions: 9.1” x 7.5” x 12.1”
  • Weight: 3.5 lbs

The Homasy 4.5L cool mist humidifier is an ultrasonic humidifier that uses nebulization to break down water into ultra fine droplets before being released into the air. As an ultrasonic humidifier, it does not have any fans or moving parts. Therefore, one of the main selling points of this humidifier is the quietness of it. It registers a mere 28 dB while in operation and is quieter than a library! If your houseplants are in your bedroom or study room then this is the perfect unit for you.

With a coverage area up to 380 sq. ft, this humidifier will be able to function in a medium to large living room where you may keep your plants. Able to run about 30 hours between refills, it allows you to just make one water refill per day, saving you time and energy. If you happen to be out or simply forgot to refill the water, it will just automatically turn itself off when the water has run out.

A feature that is useful when using it for plants is the 360 degree rotatable nozzle that allows you to direct the mist at different parts of plants which may need more attention. Rather than moving the humidifier, this makes it much easier for you.

As mentioned before, the humidifier will require a refill almost every day and it just makes sense to get one with easy refilling. As a top fill humidifier, this unit definitely meets the criteria of easy refill and you never have to worry about wiping the floor during refilling. 

One limitation with this humidifier is the difficulty in cleaning. The water tank is large and easy to clean. However, the other parts and components of this humidifier can be pretty small and difficult to reach. Therefore, I would suggest avoiding hard water when using this humidifier to reduce the build up of scale. Go for filtered water or distilled water.

All in all, it is a solid humidifier that will humidify your plants well with minimal fuss. There is a bit more work involved in cleaning but you can make your life easier by using filtered water.

Pros

  • Quiet during operation – 28 dB
  • Top fill for easy refilling
  • Adjustable mist output mode for different environments
  • Water-less auto shut off 
  • Good running time of 30 hours

Cons

  • Small parts are difficult to reach and clean
  • Will need filtered or distilled water

What their fans love: “It’s easy to use and setup. I don’t hear any noise at all. My plants always get so dry when I wake up in the morning because I always keep the AC on. This machine keeps the air in my room moist. After a couple days, I can see the difference in the plants when I wake up!“


Homech Quiet Ultrasonic Cool Mist Humidifier

Best Quiet Humidifier For Houseplants

Product Overview

  • Coverage area: 215 – 430 sq. ft. / 20 – 40 sq. m.
  • Water tank capacity: 1 gallons / 4 litre
  • Refilling: Bottom fill
  • Running time: 12-50 hours 
  • Dimensions: 10.2” x 6.5” x 13.3”
  • Weight: 4.8 lbs

The Homech cool mist humidifier is an ultrasonic humidifier that uses nebulization to generate cool mist for the room. Designed for small to medium sized rooms, it comes equipped with a 1 gallon water tank that can run for up to 50 hours (on the lowest settings) for areas up to 430 sq. ft. If you are like me who is always lazy to refill water then this humidifier is a great fit because you can go almost 2 days without refilling it and your plants will still be well humidified.

As an ultrasonic humidifier, quietness is one of its selling points. It also uses weakened water flow technology and dustproof sponge to further lower the noise level to an almost indiscernible 26 dB. It is the quietest humidifier in our review and we would recommend it if your plants are in your bedroom or study room.

In terms of portability, this humidifier also gets a thumbs up from me. There is a convenient carrying handle that separates the water tank from the base so you can transport it easily even when it’s full or slippery. The unit itself is also very compact and lightweight. Weighing at just under 5 pounds, it is easy to bring around without any difficulties.

Other features include a 360 degree rotatable nozzle to direct the mist towards your plants, water-less auto shut off to protect against dry burn.

One feature that I wished for it to be changed is that it is a bottom fill humidifier. Generally bottom fill units are just more troublesome and difficult to refill. Thankfully, this unit can go pretty long between refills so it is not that painful. 

Another limitation is that it does not have an inbuilt humidistat so it cannot detect the humidity levels of the room and make adjustments automatically. Users will need to purchase their own humidistat to supplement this unit. 

Pros

  • Very quiet
  • 360 deg nozzle to direct mist
  • Lightweight and portable
  • Long running time between refills

Cons

  • Bottom fill is more troublesome to refill
  • No inbuilt humidistat

What the fans love: “I’m using this humidifier not for myself but for my tropical indoor plants. I love the 4L capacity which means I only have to refill the reservoir every other day or longer depending on the strength of the mist I select. I leave it running for around 15 hours each day. The all white design has a clean and modern look and matches with any room. The 360 degree nozzle is helpful if I want to shift the mist to other plants. The handle also makes it easy to carry the reservoir over to the sink.”


Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier

Best Portable Humidifier For Houseplants

Product Overview

  • Coverage area: 250 sq. ft. / 25 sq. m.
  • Water tank capacity: 0.3 gallons / 1.5 litre
  • Refilling: Bottom fill
  • Running time: 16 hours 
  • Dimensions: 8” x 6” x 9”
  • Weight: 2.3 lbs

The Pure Enrichment MistAire humidifier is an ultrasonic humidifier which puts out cool mist as its mode of humidification. It comes with a 0.3 gallon water tank that can run for 16 hours between refills. With a coverage area of about 250 sq. ft., it is a comfortable fit for a small sized grow room. For those of us with a small balcony of houseplants, this humidifier will be more than sufficient to provide the necessary moisture for your plants.

With two different settings of mist speed, users will have some degree of control over the amount of humidification needed. There is no inbuilt humidistat for complete customization so you will need a separate humidistat if you desire a tight control of humidity level at home. There is a 360 degree rotatable nozzle that allows you to direct the mist towards the plants you want and away from areas which do not need so much moisture.

Quietness is also one of the features of this humidifier. It is whisper quiet and will not disturb the peace and quiet as you enjoy the beautiful greenery on your balcony. Other features include waterless auto shut off and it comes with a cleaning brush to with the small spaces while maintaining your humidifier.

Perhaps the most defining point of this humidifier is how light and portable it is while still maintaining a decent amount of humidification. Weighing just slightly 2 pounds, you can bring this humidifier anyway, be it your home or office. That makes it so much more flexible than just a humidifier for your plants.

Do note that this is a bottom fill humidifier so you will need to remove the whole tank while refilling. Generally, a bottom fill humidifier is less convenient than a top fill humidifier and requires a bit more work.

Pros

  • Light and portable
  • Easy to clean
  • Decent humidification for a small humidifier
  • Quiet

Cons

  • Bottom fill is more troublesome to refill
  • Distilled or filtered water preferred

What the fans love:”Love the small humidifier I purchased — I use it in a bedroom and it makes a tremendous difference! So quiet you don’t know it’s on and provides just the right amount of moisture to keep me breathing easy all through cold weather months.”


Frequently Asked Questions (FAQs)

Q: Which is better, cool mist or warm steam humidifier?

A: Both humidifiers will do a good job of humidifying the room so it really depends on your specific needs when trying to determine which is the better humidifier. If you want a unit that is quiet then a warm steam humidifier is better in that aspect. If you prefer a child-friendly humidifier that is safer then go with cool mist. There are many other considerations to understand. For more information, visit our guide on the types of humidifiers!

Q: When should I use the humidifier for my plants?

A: You should use the humidifier more during the day because there are higher levels of evaporation during the day. Plants lose a lot of moisture from the soil and their leaves during the day so it is important that these moisture get replaced with a good level of humidity. 

You do not need to use the humidifier for your plants during the night as there is much lesser evaporation with the lower ambient temperature. Excessive moisture in the soil can also cause damage to the roots which is harmful to the plants. 

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

Q: What type of humidifier is best for plants

A: Evaporative and ultrasonic humidifier with cool misting is the best for plants. They provide good levels of humidification and get the job done with minimal fuss. Warm mist humidifiers are not recommended as some warm mist can be very hot and damaging to the plants. Air washers are more expensive due to the air purification feature which is usually superfluous for plants. 

When choosing humidifiers for your plants, you should also consider if you might want to use the humidifier for other purposes as well. If so, then you can consider humidifiers with flexible settings such as dual mist (cool and warm) or air purifier-humidifier combo units.

Q: Is cool mist or warm mist better for plants?

A:  Generally cool mist is preferred for plants because there is no danger of injuring the plant with warm mist that is too hot. However, there are some models which can adjust the temperature of the warm mist. If you prefer a humidifier with warm mist, you may look for such models or choose a unit which has both cool and warm mist functions.

Another consideration is the energy efficiency. Warm mist humidifiers are usually more energy efficient because the conversion of water to steam is 1:1. This means that 1 gallon of water in the water tank translates to 1 gallon of steam/vapor. For cool mist humidifier that uses evaporation, you will require 10 gallon of water to get 1 gallon of vapor.
