TaoTronic TT-AH018 Warm And Cool Mist Humidifier

Best Overall Humidifier For Arizona Weather

Product Overview

  • Coverage area: 450 sq. ft. / 40 sq. m.
  • Water tank capacity: 1.45 gallons / 5.5 litre
  • Essential Oils Compatibility: No
  • Refilling: top fill
  • Running time:45  hours
  • Dimensions: 10.2” x 8.07” x 12.6”
  • Weight: 6.8 lbs

The TaoTronics TT-AH018 warm and cool mist humidifier is an ultrasonic 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. For consumers like me who could never decide whether a cool mist or warm mist was better, this is perfect. 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 and light sleepers.

With a coverage of about 200 to 450 sq. ft., this humidifier is good for a medium sized 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 user’s preferences. There are also two 360° nozzles which enable the user to direct the mist where they want it.

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!


  • Has warm and cool mist for different seasons
  • Able to customize mist temperature to suit one’s needs
  • Quiet during operation
  • Long running time between refills
  • Top fill makes for easy refilling


  • Generate white dust during operation

What the fans love: “This humidifier works excellent for my large master bedroom. It has a large water tank so I do not need to change water everyday. The part I love most is that it comes with sleeping mode which is really quiet. The design is awesome. It is easy to set up with a phone and to clean the inside of the tank. Highly recommend this humidifier.”

Best Humidifier For Arizona Weather Buyers’ Guide

How Humid Is Arizona

In order to tell how humid Arizona is, let’s take a look at the average humidity levels between the years 1961 to 1990 for place in Arizona. The table below gives the daily average humidity along with the highest and lowest relative humidity levels. 

PlaceAverage HumidityHighest HumidityLowest Humidity
Humidity levels in Arizona

With the exception of Flagstaff and Winslow, the other places in Arizona all suffer from low humidity as their average humidity all lies below the ideal level of 40%. Statistics don’t lie and these hard facts tell us very clearly that homeowners will need some form of humidification in order to hit the minimum optimum humidity levels of 40%.

What Is The Best Humidity Level For Our Homes

The most ideal and most comfortable humidity level to aim for is between 40% to 60% relative humidity. Studies have shown that this is the most optimum range of humidity for human health and comfort. 

While it may seem logical that higher humidity will be better for such a dry climate, anything beyond 60% can cause other problems like increased growth of mold, fungus and viruses. Therefore, try to keep the humidity levels regulated between 40% to 60%

During winter, where humidity drops to 20% and lower, a humidifier would be a lifesaver for conditions such as dry skin and dry eyes.

What Type Of Humidifier Is Best For Arizona Weather

Humidifiers can be broadly categorized into 4 main types

  • Evaporative
  • Ultrasonic
  • Steam Vaporizer
  • Air washer

While each type of humidifier has its pros and cons, homeowners will be glad to know that there are no specific type of humidifiers that are just for Arizona weather. In other words, all 4 types of humidifiers can be used if you are suffering from dry skin. However, each type has their own unique selling points that may be applicable to other aspects of your life.

Considerations When Choosing Humidifiers For Arizona Weather

Coverage Area

When choosing your 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 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.

If a humidifier cannot be cleaned properly, there will be buildup of lime, mold and fungus and these particles can get released into the air when the humidifier is working. 

When choosing a humidifier, definitely go for a unit that can be cleansed easily and thoroughly. This ensures that the water that is released is clean, fresh and healthy. 

Running Time

Some of us find that when we wake up in the morning, our skin becomes dry and scaly and our lips become cracked. This is usually because the air at night is cooler and drier. For homeowners looking for a humidifier to use overnight during their sleep, the wise thing to do is to find a humidifier that can at least run continuously overnight without the need for a refill. 

Homeowners can look at the running time of the humidifier when choosing their humidifier. At least 12 hours on their highest setting is recommended for overnight usage. Some units boast a long running time but only on the lowest setting. So… read the fine print!

Noise Level

For many of us living in Arizona, the weather at night may get even drier and colder and we frequently wake up in the morning with dry throats and dry lips. Therefore, we would most likely be using the humidifiers in our bedrooms while we sleep. Hence, having a quiet humidifier that runs silently is crucial for us to get a good night’s rest. 

When choosing quiet humidifiers, ultrasonic humidifiers and steam humidifiers are usually much quieter than their evaporative and air washer counterparts. This is because there are less moving parts in ultrasonic and steam humidifiers.

Best Humidifier For Arizona Weather Product review

Honeywell Cool Moisture Console Humidifier

Best Humidifier For Whole House In Arizona

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.


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


  • 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 Humidifier For Baby Room In Arizona

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. 


  • 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


  • 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.”

Levoit LV600HH Hybrid Ultrasonic Humidifier

Best Humidifier For Large Rooms Arizon

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.


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


  • 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!”

HuPro Premium Ultrasonic Cool and Warm Humidifier

Best Quiet Humidifier For Arizona Weather

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.


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


  • 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.”

best place to put humidifier

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: What is ideal humidity level at home?

A: The ideal range you want to keep your home at is between 40% to 60% relative humidity. This is the best range of humidity to maintain comfort at home and also to reduce direct and indirect health effects.
