If you are wondering what makes this model from Honeywell so popular among buyers, let us shed some light on this subject. Not only that it is very practical, with a large 3.8 L water tank included, that ensures its optimal functioning for up to 24 hours, but it features an innovative filtering technology, based on
Ultra Violet light and
wicking filters, designed to release only germ- and particle-free mist into the air. With HCM350W you won’t have to worry about breathing calcar deposits that are an effect of hard water and may get sprayed into the air with other humidifiers.
Honeywell has another option just as worthwhile for those interested in raising humidity indoors. The Honeywell HUL520W is the product we are talking about. The difference is that this particular model is suited for smaller areas of up to 120 square feet and holds 1.9 liters of water tops in the tank. Considering that the peak mist output is 200 milliliters per hour, the approximate runtime is of 20 hours.
99.9% Germ-Free Mist
Studies have shown that viruses and germs multiply faster in less humid environments, so keeping a good level of humidity in your house may be the best way to avoid flu and seasonal colds. But what do you do with microorganisms that travel through water and get dissipated into your room through the cold mist? Meet Honeywell evaporative technology that includes:
- Ultra Violet Light - kills 99.9% of germs, bacteria, and viruses that are found in the water
- Wicking Filter – absorbs the sanitized water and uses it to moisturize the dry air as it passes through it
- Self Regulating System – automatically adjusts the mist output according to the humidity level in the room
The water tank is made of break-resistant materials and it is dishwasher safe. Provided with a wide tank opening, it is easy to clean and fill, thus helping to prevent any mold or bacteria growth on its interior walls.

Multiple Health Benefits
Cold weather especially can decrease the thermal comfort in your living place, favoring the occurrence of irritating symptoms such as difficulties in breathing, coughing, or sneezing. By keeping the RH level between 40 and 60%, Honeywell HCM350W reduces the risk of:
- Influenza
- Asthma
- Allergies
- Congestion
As long as you remember to replace the filter periodically, it will do a fantastic job of keeping viruses, bacteria, and other potentially harmful airborne particles away from your house. Genuine Honeywell Filters are treated with Protec Antimicrobial that stops up to 99.99% of mold growth, so we recommend the use of these specific ones.
Performance Test Feedback
We tested the Honeywell humidifier in a 160 square feet room, a bit larger than the recommended size. Nevertheless, it aces our testing trials, so it’s easy to understand why we gave it the leading position. We let the humidifier function for about 24 hours, that’s how long it took for the tank to run out of water, exactly as promised by the manufacturer. We tested humidity levels before and after using an indoor hygrometer and were pleasantly surprised to learn that this neat device increased moisture by a whopping 13%. It didn’t make much noise in the process either, so it’s safe to say that this is a viable option for bedroom, nursery, or office use. Furthermore, detaching the tank and cleaning it is as easy as it gets.

5. Levoit Dual 100
Summary: The Dual part of the name comes from the fact that this unit can be used either as a humidifier or as a diffuser. So, whether you’re looking to enjoy a soothing session of aromatherapy or you want to get rid of dry air indoors, it’s the product that you can rely on for the job.
Pros:
- Dual-purpose machine – you can use it as a humidifier or as an essential oil diffuser
- Among the quietest humidifiers available
- Comes at a cheap, accessible price
- The top-fill opening makes it easy to refill the tank when the water runs out
Cons:
- The cleaning instructions provided in the manual aren’t complete – beware that you have to take apart the lower portion of the tank and clean it too, otherwise mold will form there
- It’s a bit difficult to clean
This Levoit humidifier presents a cheap solution to get rid of the issues associated with dry winter air. Design-wise, it’s one of the most appealing options to go for due to its pleasant aspect and compact size which makes it perfect for the nightstand. Although it’s small, it fares quite well when it comes to its main function of increasing air moisture,
outputting 220 milliliters of moisture per hour when used on the highest of its 3 misting levels.
It’s a dual-function product, which means that versatility is its main trait. You can use it for humidification purposes to normalize RH levels indoors, or you can add essential oils into the base chamber to use the machine as an aromatherapy diffuser. What we urge if you want to benefit from its performance to the fullest is that you use it in spaces of up to 220 square feet, not larger. Since the tank has a 1.8-liter capacity, you won’t find yourself refilling it very often. For example, if you use it on the lowest misting level, it will run for 20 hours without interruption before the tank empties.
A feature we liked using during tests was the Sleep mode. It turns the running speed of the machine low to reduce operating noise as much as possible. It also features automatic shut-off that prevents overheating, so there’s no need to worry about safety in use with this ETL listed product. In terms of backing, the company has it covered for the first 2 years after you buy it.

Alternative Cool Mist Humidifiers Worth Checking Out
After testing 45 models for several weeks, we concluded that the 5 products we previously reviewed are the best, hands down. However, there are another 4 entries that we deem just as worthy of your attention, products that scored high in our tests. We didn’t include these alternative products in the main ranking because we considered the products in our top slightly better, but dissimilarities aren’t high, so you can choose whichever models you like without worrying about quality differences. Here is a brief description of your best alternative choices, as well as the reasons why these products didn’t make it into our main top:
#1. Honeywell HUL520W MistMate
Check Price at Amazon
A filter-free humidifier that doesn’t cost much upfront and won’t cost you a cent when it comes to maintenance. It’s a budget pick that we recommend to anyone interested in upholding proper RH levels indoors without spending much money in the process. The MistMate provides optimal humidity increase performance when used in
spaces of up to 120 square feet. It is fitted with a
1.9-liter capacity water tank that you won’t have to refill absurdly often when you use the unit in an appropriately-sized space. In fact, it should run for
18 hours when you use it on the lowest moisture release setting before you have to refill the water tank. If you happen to forget to fill it on time or you’re asleep when this task is needed, the unit
automatically turns off to impede overheating. Thanks to the
whisper-quiet operation, this is one of the preferred options for bedroom or nursery use. Of course, the
compact size doesn’t hurt either since it makes the MistMate perfect to place on the nightstand.
Why we chose to leave it out: The MistMate has a smaller area coverage and tank capacity compared to our top pick from the same brand, the Honeywell HCM350W. So we recommend that you pick this more compact, cheaper model if you don’t need as hefty coverage as provided by its counterpart.
#2. AquaOasis AO-101
One of the best humidifiers for bedroom and nursery use because of its low noise output. You can count on this col mist unit to
run for 24 hours without interruption on a full tank and when used on the lowest mist release setting. The
large 2.2-liter capacity of the water tank is what makes it so efficient when it comes to the time that passes between refills. Say that you don’t refill the tank on time, this won’t cause issues like overheating since the unit
turns off automatically when the water level is low to prevent this from happening. What we especially like is that
the nozzle rotates 360 degrees. Therefore, you can direct it as you prefer so that the mist is released toward specific locations inside the room. Best of all, it comes at an
accessible price that makes it a viable option for a wider range of customers.
Why we chose to leave it out: This otherwise great moisture-releasing unit didn’t make it into our main ranking because of how difficult it is to clean the water tank. It doesn’t come apart, so the only solution that you are left with is to fill it with vinegar and swish the cleaner around. Just make sure that you rinse the tank multiple times before using the humidifier again so that it won’t release vinegar steam into the air.
#3. Vicks VUL520W
If soothing comfort is what you need for a good night’s sleep, then look no further since this Vicks product has you covered. What makes it the go-to option is the fact that
it works with Vicks VapoPads, allowing you to enjoy the beneficial, aromatic vapors to soothe your nocturnal slumber. You get to fully customize the level of comfort that the VUL520W creates since you can adjust the mist release level with the simple turn of a knob. The
0.5-gallon water tank ensures
20 hours of continuous use when you use the lowest mist release setting. When the water tank is close to emptying, the unit
automatically turns off to prevent any damage. It’s
very quiet and comes at a
cheap price. Additionally, thanks to the
filter-free design it boasts, you spend no money on routine maintenance.
Why we chose to leave it out: Performance-wise, we were very pleased by this Vicks product during tests. But in our experience, it was very difficult to clean. After we checked online reviews of customers, we noticed that most of them complained about how hard it is to clean the reservoir as well, with some even stating that mold grew inside the recipient over time.
#4. Everlasting Comfort Humidifier
It comes at a higher price compared to most of the products we reviewed, but this is understandable seeing how the Everlasting Comfort model is fitted with a
large 6-liter water tank. Thanks to its capacity, you can count on this humidifier to release higher amounts of moisture per hour into the air. Best of all, the tank will empty at a much slower pace. It is suited for use in
large areas of up to 500 square feet, so no matter what room you want RH levels increased in, this humidifier will handle the job just fine. We are big fans of the
essential oil tray that you can add essential oils to and benefit from aromatherapy whenever you need that soothing comfort. It stays very quiet when it runs, so it is viable for bedroom or nursery use. Additionally, the manufacturer covers it against defects for
2 years after you make the purchase.
Why we chose to leave it out: The manufacturer states that the unit provides 50 hours of runtime on a full tank, but this wasn’t our experience with it, nor that of most customers. Instead, it ran for 36 hours without interruption on the lowest mist release setting before the water tank depleted. Because of this misinformation, we decided against including the Everlasting Comfort product in our top but rather only list it here as an alternative.
How Do Cool Mist Humidifiers Work?
The benefits of a humidifier cannot be contested, especially when it comes to relieving the symptoms caused by
low humidity. When the cold season approaches, nasal congestion, dry skin, and itchiness are just a step away, and the best way to fight these symptoms is to increase the humidity level in your house. Unlike
warm mist humidifiers, which boil the water to produce vapors that are further released into the room,
cool mist humidifiers work more like evaporative coolers, using the warm air as the main catalyst for evaporation. Another method that is often found on these appliances is ultrasonic technology.
The process of turning the water into a refreshing cool mist is pretty simple, and once you’ve understood how these devices work, you will be able to better distinguish between the two types and make the right choice for your home. So, let’s take a closer look at the technology behind them.
Two Effective Technologies
The years of research and innovation produced two types of cold mist humidifiers, one that uses evaporation to release the mist and increase humidity, and one that implies a spinning disk driven by a performant motor that splits the water into microscopic droplets. Each of the two methods has its benefits and drawn-backs, but when it comes to their main purpose, the result is excellent.
Evaporative Humidifier
The three components that are found obligatory in this type of humidifier are the wick filter, the water reservoir, and the fan. Although the fan size and power may vary, and the filter can be either of higher or lower quality, the process is the same, implying the following steps:
- The reservoir is filled with water according to its volume and capacity.
- Once the device is turned on, the water is drained from the reservoir into the wick through a paper sheet or a cloth.
- The fan draws the warm air into the room and blows it towards the wick, activating the evaporating process that leads to a drop in temperature.
- The cold mist is then released into the room, increasing humidity and creating a refreshing atmosphere.
Often, evaporative humidifiers use filters to remove the particles and pollutants that travel through the air. Depending on the quality of the filter, they can capture bacteria, germs, viruses, pet hair, dust mittens, mold, mildew, fungus, and even odors or VOCs.
Renowned for their whisper-quiet operations and efficiency, ultrasonic humidifiers cannot function without 3 main components: the water recipient, the nickel electrodes, and the piezoelectric ceramic disk. Here’s how the process follows:
- Once the recipient is filled with water, the device is turned on.
- The electric current crosses the 2 nickel electrodes and reaches the disk.
- As the disk is piezoelectric, it starts to vibrate at an ultrasonic frequency which breaks the water molecules, turning them into smaller particles.
- The mist is instantaneously transmitted through the air into the room, all at an inaudible level of sound.
Ultrasonic humidifiers don’t use filters, as the high vibration process is powerful enough to sanitize the air. However, water deposits such as minerals or chlorine are broken along with the water molecules and end up in the air. This fine powder is known as ‘white dust’ and, although it is not dangerous for your health, it tends to deposit on the proximal furniture. An efficient way to ameliorate this problem is to replace the tap water with distilled water or try to find milder water.
Benefits
Whether you choose the first or the second variant, the most important benefit is the improvement it brings to your health. Cold and flu symptoms will be alleviated and allergies reduced. Plus, during the summer, the cool mist will refresh the air in your house and drive away a small part of the summer heat.
However, a cool-mist humidifier can also bring you financial advantages, and these include:
- Low power consumption – it is designed to save energy, and many models include a timer, so you can set the optimal operation time.
- Attractive prices – although variable, depending on the technology, options, and smart functions, the average price remains within reasonable limits.
- Low maintenance – Ultrasonic humidifiers don’t use filters, so you won’t have to deal with extra expenses. Moreover, even if evaporative humidifiers use them, they are pretty affordable and last for many months, so the maintenance cost will remain low.
Conclusion
Cold mist humidifiers run on ultrasonic vibrations, a technology that provides effective results without consuming much energy, thus turning them into real money savers. Many of them are equipped with large tanks that are easy to fill and clean and can run for tens of hours without interruption. Furthermore, their main function is supplemented by many attractive features that increase their usability and turn them into genuine gadgets. We presented you with the best options this market offers previously, and before we end, we want to briefly go over a few of the standout models to help you decide if you haven’t made up your mind yet. Here it goes:
Best Cool Mist Humidifier for sale: Honeywell HCM350W
The complex features, reliable performance, and design work together to make this Honeywell entry the best money can buy. When used in a 150 square feet area, the humidifier provides continuous mist release for up to 24 hours before you have to refill the large 3.8-liter water tank. It’s silent, which makes it the usual go-to for nursery and bedroom use. Thanks to the UV light and wicking filters, you can fill the tank with tap water without worrying that the mist released into the air is polluted since the aforementioned technologies handle removing bacteria and contaminants. Moreover, it is capable of automatically adjusting its moisture output to maintain your desired humidity level.
Editor’s choice: Crane EE-5301
What makes this Crane humidifier our favorite is that it covers very large spaces. You can count on it to increase humidity in areas of up to 500 square feet, which makes it more hefty performance-wise even compared to the top-rated Honeywell HCM350W. The materials that go into the manufacturing of the water tank impede germ and bacteria growth. Therefore, you don’t have to fear that the mist released can harm your health in any way since it’s sanitized. Best of all, it features a 360-degree rotating nozzle that lets you direct the mist wherever you want.
Best Cool Mist Humidifier for the Money: Pure Enrichment PEHUMIDIF
What makes this Pure Enrichment product the best for the money is a combination between the reasonable asking price, reliable performance, and features. It turns off when the tank is low on water. The nozzle rotates 360 degrees, allowing you to direct the mist where you like. Since it’s filter-free, maintenance doesn’t cost you a cent. It features a soft nightlight that soothes you into sleep if you use it in the bedroom. Additionally, the company backs it against defects for 5 years as of acquiring it.
