The Ultimate Review of the Best Humidifiers in 2021

1. GENIANI Smart Aroma Ultrasonic Humidifier – The Best Overall

1. GENIANI Top Fill Cool Mist Humidifier

The Best Overall

This is a smart humidifier that can automatically maintain the ideal moisture level in your house thanks to its integrated intelligent sensor.

For manual operation, you can select low, medium or high setting to quickly humidify the air or maintain the quietness at 38dB noise level.

You can put the GENIANI Smart Aroma Ultrasonic Humidifier in your kid’s bedroom or yours without any fear. It has a night light mode to aid human sleep (you can turn this off) and can shut itself down when the water runs out.

If you love the scents of essential oils and their great effects for health, just add some drops of essential oils to the water tank and turn on the diffuser mode.

Refilling this machine is easy as pie. We just need to pour water through the tiny insert on the head of the appliance without removing its cap. To clean it, simply detach the lid and use a cloth to wipe the empty tank.

Owing to the clear water gauge, users can observe the water level inside the large 4-liter water tank and estimate when they will need to refill the tank effortlessly. However, this might be unnecessary because the unit can run for 18 – 24 hours with a full tank.

2. Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier

The Best Humidifier for Bedroom
Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier - Premium Humidifying Unit with Whisper-Quiet Operation, Automatic Shut-Off and Night Light Function - Lasts Up to 16 Hours
Pure Enrichment

The Pure Enrichment PEHUMIDIF is one of the most popular options for bedrooms. With a 1.5-liter water container, the machine can cover a moderate area of 250 square feet overnight.

The transparent tank mounted on the top of the humidifier enables users to view the remaining water level without effort. Thus you can calculate the next refill time in seconds.

However, as we have just mentioned, as this machine is engineered to run overnight (around 12 hours), there is no urgent need for you to worry about refilling it regularly. Besides, it has an auto-shutoff function, so it is still okay if you forget to refill the tank sometimes.

What we love is its 360-degree nozzle in insanely hot summer days. This component helps the device to distribute cool mist quickly and in all directions.

In addition to the cool feeling, the equipment also brings about a gentle blue glow night light and whisper-quiet operation that give us perfect sleeps as well.

In spite of being in the low price range, this product still comes with a premium warranty of up to 5-year, which is even longer than many premium models in the market.

Nonetheless, as a humidifier designed for bedrooms, the Pure Enrichment PEHUMIDIF can hardly provide enough power for larger rooms and run for a longer time.

3. TaoTronics Cool Mist Humidifier

The Best Humidifier for Baby
TaoTronics Cool Mist Humidifier, 4L Ultrasonic Humidifiers for Large Bedroom Home Baby, Quiet Operation, LED Display with Humidistat, Waterless Auto Shut-off (1.06 Gallon, US 110V)

This model is equipped with a detailed and intuitive control panel. It allows you to monitor the current mist level, working state, current humidity, and low water indicator to make necessary tweaks in time.

In addition to the humidistat and the LED display for fine-tuning settings, the appliance comes with a mineral filter to prevent white dust from escaping into the environment and harming your children, too.

Nevertheless, this means that the pollutants will still remain inside the water tank, and you should clean it with vinegar periodically.

When your babies need to sleep, you can switch from the night light to sleep mode, leave the machine work at the lowest setting to reduce the noise to under 38 dB.

With a 4-liter tank capacity, this unit can work for a half to a full day over a space of 107 to 322 square feet, depending on the setting you configure it to work.

4. Honeywell HCM350B Germ Free Cool Mist Humidifier

The Best Cool Mist Humidifier
Honeywell HCM350B Germ Free Cool Mist Humidifier

When the summer comes, and extreme heat visits your home, the Honeywell HCM350B will be your best savior with its super-cool mist.

This sturdy unit allows users to switch between three different speed settings, giving more control over the rate of adding cool air and moisture as well as the quietness level.

The selling point of this humidifier must come from the antimicrobial design. Unlike conventional humidifiers, the Honeywell HCM350B utilizes a wicking filter to eliminate impurities like mold spore, bacteria, and germs, bacteria from the water.

While the most time and effort-consuming work in using a humidifier is refilling, the manufacturer has eased your burden with a wide opening on the top of the water tank.

Thereby, users can pour water in and out of the reservoir as well as clean it conveniently. Besides, the water tray and container are able to be washed by a dishwasher, too.

And, of course, because of the antimicrobial design, cleaning the humidifier by hand will also a breeze for anybody. Since the UV technology has killed 99.9% of bacteria inside the water tank, the mold, mildew, and other residues left there are negligible.

Anyway, there is no challenge in cleaning the machine. The tank opening is large enough for us to clean it with our whole hand inside. Simultaneously, this design also allows you to fill the tank in a few seconds.

5. Honeywell HWM-705B Filter Free Warm Moisture Humidifier

The Best Warm Mist Humidifier
Honeywell HWM-705B Filter Free Warm Moisture Humidifier

Well, the models above are going to add cool mist to help you in the summer, so they will freeze you in the winter? Don’t worry. Here is the best humidifier you can use this winter to add some comfortable and warm mist.

This super-quiet humidifier generates a soothing warm mist that we can even see with our naked eyes to create a cozy atmosphere all over your rooms.

With this handy companion, you can counteract all the harmful effects of the harshly dry winter air, such as dry skin, cracking lips, nasal congestion, and many more.

If you are suffering from severe illness, the medicine cup included within the box will help you add liquid inhalants to the mist.

The 1-gallon tank enables the unit to run for the maximum time of 24 hours at the most energy-saving mode. Plus, there is a reset light informing you when the water runs out. If you cannot refill the reservoir in time, the humidifier will turn itself off.

Using this model is one of the most straightforward things we have done in our life. There are only two humidity output settings, and all adjustments are made with a knob.

Similar to the majority of Honeywell products, the Honeywell HWM705B is an affordable option for people on a tight budget. Yet, sadly, this cheap model is not well-constructed and seems to be flimsy.

You should treat it with care and maintain it well. Or else, the humidifier will not last for very long with broken parts and leaks.

6. 6L Cool Mist Humidifiers Quiet Ultrasonic Humidifier

The Best Humidifier For Large Rooms
6L Cool Mist Humidifiers Quiet Ultrasonic Humidifier

Humidifying a part of the room is insufficient for you? As the best humidifier for large rooms, the Homech HM-AH003 promises to go beyond your expectations.

This beast has a massive water tank that holds up to 6 liters of water, which is equal to 1.6 gallons. Hence, it can operate continuously for up to 100 hours at a mist output of approximately 60 to 300 ml per hour.

As such, you will rarely have to refill the reservoir. But it will cost you a remarkable effort every time you do this because you will have to fetch 6 liters of water.

Luckily, as the opening is 3.54 inches in width, pouring water through it and cleaning the water tank will not cause you many difficulties.

To deliver moisture to every crevice in your home, the unit features a robust fan and 360-degree rotating nozzle that disperse mist at the high of 3.28 feet over an area of 215 – 430 square feet.

So, as a portable humidifier, the Homech HM-AH003 cannot be so efficient as types of whole-house humidifiers that are built into the HVAC system. Yet, it is the most effective humidifier for large rooms.

Quite unbelievably, notwithstanding being a heavy-duty humidifier intended for massive spaces, this big boy can produce sound as quiet as under 27 dB, which is much lower than smaller models.

Thanks to the nano-coating protecting the circuit board, solid construction, and auto-shutoff function, the unit will last for a long time even when you run it consecutively for months.

7. Pure Enrichment MistAire XL Ultrasonic Cool Mist Humidifier

The Best Ultrasonic Humidifier
Pure Enrichment MistAire XL Ultrasonic Cool Mist Humidifier
Pure Enrichment

Manufactured by the famous brand for ultrasonic humidifiers, it is easy to understand why the Pure Enrichment PEHUMLRG is the top-rated ultrasonic humidifier for a good reason.

This model features a small 1-gallon tank to reduce weight and size, yet still sufficient for humidifying a medium room. This tank is totally clear so that people can directly monitor the remained water.

Nonetheless, given that a full tank will not run out in less than 12 hours, you will not have to replenish it too regularly. And the standard auto-shutoff feature is also available.

Furthermore, the 360-degree nozzle facilitates convenient speed and directional adjustments just in moments. In combination with the ultrasonic technology, the dry air in the room will soon be replaced with moist air from the machine.

This compact device is almost silent and supplies a blue night light to soothe your stress and aid your sleep all night long as well.

You will need to clean the unit weekly because if you do not do this frequently, the residue will be harder to remove inside the tank. Thankfully, there is a brush included in the box for easier cleaning tasks.

One thing that brings about peace of mind for any customer is the industry-leading 5-year warranty of Pure Enrichment. This makes sure to keep troubles away from you and guarantees a good bet.

What many customers may find unsatisfactory about this humidifier is that it might be too small and light-duty for larger spaces. So if you want something more powerful, this is surely not your right choice.

8. LEVOIT Humidifiers for Large Room Bedroom

The Best Whole House Humidifier

Your entire home is devastated by dry air, or you often move from room to room? It seems that you would appreciate this whole-house humidifier.

The Levoit – LV600HH is designed to handle extra-large spaces of up to 753 square feet, so given that the average area of houses is around 650 square feet, nothing can stop this monster.

However, be patient while the machine is working. This is still a portable model rather than something that can be integrated into your house’s HVAC system. What’s more, a massive area will take a while to be completely humidified.

Its 6-liter tank is the same as that of the Homech HM-AH003. However, the advantage of the LEVOIT LV600HH is the user-friendly LED display. On this screen, you can read real-time information on the working state of the device and the current humidity.

The electronic controls and the remote share the same interface, including buttons On/off, Mist level, Humidity, Timer, Warm, Auto. With the user manual, even our kids can use the device.

We find this model appropriate for many people in various cases. It can produce either a warm or cool mist as well as work as a fan-drawn essential oil diffuser.

Sadly, without filter and pure water, this unit will spray pollutants all over your home. Since you do not have to waste time cleaning the filter, pay attention to the water quality.

9. Frida Baby Fridababy 3-in-1 Humidifier

The Best Small Humidifier

If you often travel a lot, a super-compact humidifier is what you should pack in your luggage. But do small humidifiers provide sufficient moisture and features? In most cases, they typically have limited capacity and functions, except for the FridaBaby 053.

Although as small as a bottle, this unit can run for up to 12 hours at the lowest setting and offer full three functions that a bigger humidifier can perform.

At first, we could not believe that there was such a functional humidifier at such a modest size. With a twist of the tiny knob, you can enjoy various humidifying modes from mild mist to a tropical rainforest atmosphere.

Additionally, you can add any aromatherapy essential oil to the BPA-free 0.5-gallon tank of this mini diffuser to perform some therapies or simply make the air more comfortable to breathe.

Despite being smaller than other models, the FridaBaby 053 manages to distribute dampness over a decent area of up to 320 square feet, which is even larger than the coverage area of many bigger humidifiers.

With this unit, you will also not have to buy a nightlight since it can automatically change between a wide range of nightlight colors should you turn this mode on.

Like many other customers and us, you must have completely changed your point of view about this little bottle of water. It is a 3-in-1 device, indeed!

10. Brondell Air Purifier O2+ Revive Air Purification System with Humidifier

The Best Humidifier For Allergies

The last choice in our list is a shining candidate for people who are suffering from allergies and respiratory problems. It is not only a high-quality humidifier but also an excellent air purifier.

In other words, this is a 2-in-1 machine, and this also amplifies its effects in improving and refreshing the air. All the annoying symptoms of dry and contaminated air will disappear soon after you turn on the device.

In fact, it is proven to relieve sinus congestion, stuffy nose, dry skin, asthma symptoms, and is recommended by numerous therapists and physicians.

Thanks to the advanced dual suction system, the Brondell PR50-W can improve the air quality much faster than machines at the comparable size.

This unit has a True HEPA filter to remove 99.97% of airborne particulates and allergens larger than 0.3 microns, a granulated carbon filter to get rid of gaseous pollutants, and an off-gassing reduction filter to remove invisible substances such as VOCs or formaldehyde.

While most people overlook this, the purer air also helps the evaporative humidification method work more efficiently because the moisturized air can travel more easily.

It is not so strange that such a smart device offers up to four specialized operating modes. In Eco Mode and Auto Mode, the machine will automatically control the airflow speed depending on the air quality that its built-in sensor can analyze.

In Allergen Mode, the appliance runs at the maximum speed to eliminate allergens quickly. And the Manual Mode is for making detailed adjustments as you like.

What To Consider When Picking A Humidifier

There is hardly any “one-for-all” electronic device that can suit all uses. Therefore, to find out the most appropriate model for yourself, you have to analyze your case and use the following useful information and tips.

Go on! Let’s learn what we should know.

1. Types Of Humidifiers

Evaporative Humidifiers

Evaporative humidifiers feature a large sponge-like filter to fetch water out of their tanks and enable dry air to go past to get moistured. This means that there is a relatively huge fan to pull and push air in those models, and it is likely to be noisy, which is inappropriate for bedrooms and offices.

The damp air goes out in the form of invisible vapor instead of the billowing cloud that you see from an ultrasonic humidifier. However, it is still a cool-mist but not steam.

The most significant benefit of this kind of humidifier is that since the capacity of air for holding moisture is limited, the evaporation mechanism would work faster when the ambient air is dry.

Nonetheless, this also means that when the air reaches a decent humidity, the effect of the machine will decrease gradually.

Another remarkable downside is that the filters of these devices may collect minerals in your tap water and become crusty over time, if not brown. If you use these appliances every day, it is necessary to replace their filters every one or two months.

Besides, you ought to let the filters dry and store the machine properly anywhen you do not use it. If the machine does not work for a week when water is still inside, non-mineral things can grow on those filters, too.

Ultrasonic Humidifiers

Ultrasonic humidifiers, as known as “nebulizers,” utilize ultrasonic frequency from a vibrating disc to create diminutive vibration pulses that vaporize water molecules to turn them into a mist. Users can see the mist rise, settle, and swirl around for hours.

Then, a small fan (often in larger models) is responsible for pushing the vapor farther out into the ambient environment. However, the fans of ultrasonic models are much smaller and quieter than the fans of evaporative humidifiers.

Actually, they are nearly silent and are the quietest options. Thus, they are perfect for bedrooms and offices.

In addition, ultrasonic humidifiers are low-maintenance due to no filter. As a result, you will not have to spend time and money cleaning or replacing the filter.

Of course, these machines still have some drawbacks. No matter how moist the air has been already, they still generate the same amount of humidity. For this reason, once the air is saturated, you are likely to see a puddle under your device.

But this is not the end yet. The most terrible issue with ultrasonic humidifiers is the quality of water you pour into their tanks. The vapor that comes out from the machine consists of the same ingredients in your water.

Therefore, if there is harmful stuff in the water or the tank is too dirty, the air will be polluted. If your tap water is not reliable, you had better utilize distilled water or buy models with filters to trap pollutants before they get into the vapor. That’s said, cleaning the tank regularly is mandatory, too.

As you could see in the comparison table at the top of this article, cool mist ultrasonic humidifiers are ruling the market. Still, there are a few models that can produce both either a warm or cool mist.

Cool Mist Humidifiers

Cool mist models can use either evaporative or ultrasonic mechanism to create the cool mist. They typically have a tiny fan to broadcast cool air, so they pose no burn risk related to heating elements and are safe when used near pets and children.

However, mold and mildew are more prone to grow inside cool mist models than warm mist ones. Consequently, users have to clean them more regularly and are advised to use distilled water.

Ultrasonic cool mist humidifiers have no filter, which means there is one fewer component to clean, and you do not have to replace anything. But it is often recommended that you use distilled water in this type of humidifier.

Yet, evaporative cool-mist humidifiers use a filter (sometimes known as a wick) to pick water from a tank at the bottom. A fan will blow the dry air across this wick to get moisturized before propelled out of the device.

And as we mentioned earlier, these models require users to periodically clean and replace filters after a specific time.

Warm Mist Humidifiers

Simple as its name is, a warm mist humidifier delivers dampness for the air via a warm mist. Its operative mechanism is straightforward, like a boiler. The water will be heated to the boiling point to become warm steam, which is then released into the air to increase the humidity there.

Since the hot steam will escape the machine without the help of any fan, warm mist humidifiers are almost silent.

A significant advantage of these appliances over their cool mist rivals is that boiling water can kill most microbes. Thus, the mist will be cleaner, and you will also not have to clean the machine regularly.

Nonetheless, warm mist humidifiers generally cost more energy than other models because they consume a lot of electricity to heat water. In addition, boiling water and hot steam is dangerous for pets and children.

Whole House Humidifiers

If you need high humidity over a large area, a whole-house humidifier is your optimal choice. To install this type of humidifier, you need to have professionals connect it to the ductwork and water supply of your house.

The three main kinds of whole-house humidifiers are steam, reservoir, and flow-through. You should discuss the disadvantages and advantages of each model with HVAC experts to know which is the best option for your house.

Remember that only steam whole-house humidifiers are able to work independently with the furnace. In other words, a reservoir or flow-through whole-house humidifier will restrict you to seasonal use.

In spite of the high expense for purchase, installation, and operation, a whole-house humidifier is great for moistening the air all over your home simultaneously.

Besides, whole-house humidifiers often have extremely low maintenance requirements compared with portable models and no need to refill the water tank.

2. Coverage Area

There is no point in humidifying a part of the needed area because dry air will soon saturate with the humid air that your device produces. Besides, people and objects are still under the bad influences of dry air in uncovered areas.

Therefore, it is crucial to determine the area that you need your humidifier to distribute moisture. This factor is intimately associated with the discharge rate and the water container size of the device, as well as the humidity level of the air.

The information on the square footage of a humidifier can be found on marketing materials, the packaging, or on the Internet.

Generally, there are three basic sizes of humidifiers that you can buy:

  • A portable (Tabletop) humidifier for travel or personal use is usually effective for a small area of 25 to 100 square feet. Its water tank is small, so you will have to refill them frequently.

These devices are cheap and compact. With the smallest models at the size of a water bottle, they can be easily moved between places and put on a desk or nightstand.

  • Console humidifiers are bigger machines that stand on the floor and offer higher-capacity water reservoirs that need less regular refilling than portable models. Depending on the model’s capacity, they are the optimum option for areas of up to 1,000 square feet.
  • Whole-house humidifiers are large-scale humidifying systems that can cover a vast space of over 1,000 square feet. The pros and cons of this type of humidifier are just as we have discussed above.

3. Tank Design

For the majority of humidifiers, it is not obligatory yet still important to feature a good tank design to enhance user experience.

Select models with wide openings so that you can refill and clean the tank more easily. A transparent or translucent tank is also convenient for you to observe the amount of water remaining inside.

Also, it goes without saying that a larger tank requires less frequent refilling, but it makes the machine heavier and bulkier as well. If you are a busy person, invest in a humidifier that can turn itself off when the water tank is empty.


A built-in humidistat will show users the real-time data on the humidity level in the ambient environment. In smart models, this piece of equipment can automatically monitor and regulate your room humidity according to your settings as well as turn off the machine when the desired humidity level is achieved.

Although it is not a critical feature, it is a favorable add-on for busy people and those having difficulty in maintaining a suitable moisture for their home.

Air Sanitization

If you or any members of your family are suffering from allergens, we suggest using a humidifier that can sanitize the air (although, of course, it is incomparable to a specialized air purifier).

Such a model would have a pre-filter to catch dust mites, pollen, pet dander, mold spores, and other tiny particles in the air that may get into the device and be delivered into the air again later.

Because there also might be harmful bacteria, germs, pathogens, mold spores, and so on in the water tank, some machines come with a specialized UV light filtration system to get rid of them, keeping both the water tank and the released mist much cleaner.

Besides, some manufacturers also use silver ion or nanotechnology in their humidifiers to achieve better sanitization performance. Although these models are more expensive, they worth it.

However, don’t be too subjective and totally depend on your equipment. It is still necessary to check the internal parts and do some cleaning periodically.


As the majority of humidifiers are deemed small household devices, their warranty policy is often limited. Commonly, there are products backed with a one-year limited warranty that covers flaws in workmanship or manufacture.

For premium models, the warranty period can increase up to three years. Expensive whole-house humidifiers can be covered for up to five years or even more.

Whichever model you buy, be sure to check its warranty information since this can decide the quality and value of your investment.

Other Critical Features To Consider

  • Rate Controls:

If your humidifier does not come with a humidistat to turn itself on and off, a function of controlling the mist when the outside temperature is too low will prevent water condensation on items in your house.

  • Night Mode:

Throughout the night, you will want your humidifier to feature a night or sleep mode to turn down the light and operate more quietly, especially if you intend to put the device near your bed.

  • Oil Diffusion:

As you have seen in the list above, there are a few humidifiers that allow users to add essential oil to a separate pad to work as a diffuser.

Yet, although these oils can blend within the mist, they are not so effective as when dispersed by a dedicated diffuser. So if you have no high requirements, you can give it a try.

  • Auto-shutoff

If you may have to leave your equipment running without your supervision for a long time, the auto-shutoff function will help to reduce energy wastage and prevent the humidifier from burning if the water tank runs out.

  • Demineralization Cartridge

If your tap water is hard water, we highly recommend using a model with a demineralization cartridge. A demineralization cartridge is an extra filter that collects types of minerals naturally existing in hard water and deter them from being discharged into the air because they can cause respiratory irritants.

Top-rated Brands of Humidifiers Are Ruling The Market


Although Honeywell is mainly famous for its household cooling and heating appliances, this brand’s humidifiers are also excellent.

The majority of models are portable and cool mist humidifiers, but whole-house and warm mist models are available, too.

Maintenance Guide

We have repeated this thing throughout the article so many times that we cannot count, “please keep your humidifiers clean!”.

When it comes to humidifier maintenance, there is nothing much to do, but cleaning your device thoroughly. It is simple yet essential, so just spend a little time doing this periodically or when necessary.

Getting rid of pollutants, germs, bacteria, dust mite, and other harmful factors inside your humidifiers is protecting both you and your device.

On a weekly basis, take the following steps in order:

  1. Unplug your equipment from the electric outlet.
  2. Detach its reservoir and filters.
  3. Add a huge amount of bleach, white distilled vinegar, hydrogen peroxide, or a specially formulated cleaning agent into the base of the unit.
  4. Utilize a clean toothbrush to scrub against the film to remove dirt build-up.
  5. Next, leave the solution in the base of the device for around 15 to 25 minutes before pouring it out.
  6. Rinse by adding clean water to the base. If there is still any residue remained, redo the whole process.
  7. Leave the base dry under sunshine.


  • Drain all of the remaining water and dry the water tank of your humidifier before you refill it with new clean water.
  • Different kinds of humidifiers will need different cleaning products. For example, there are additives that should be soluted into the water in the water tank, while others need to be applied when the tank is empty.
  • Always follow the manufacturer’s manual.


1. What do humidifiers exactly do?

Humidifiers are electronic devices that increase the moisture of the air by generating and delivering steam or mist. They are designed to maintain the humidity level that you want to have in your house so that both you and your home can stay away from issues with too dry air.

Except for evaporative humidifiers that boil water in their tanks, all humidifiers will take in the dry air from their ambient environment to grant dampness to it before using a fan to blow the wet air out.

Depending on the model, some humidifiers can make the air either cooler or warmer, while some others can do both of them.

2. What can I benefit from a humidifier?

Humidifiers are great at tackling problems that are originated from dry air such as itchy skin, nose bleeds, chapped lips, allergies, respiratory symptoms, and so on.

Besides, despite its rarity, super-dry air in some climates can lead to severe damage to household objects, especially wooden ones like window, door, ceiling, floor, wall, bed, wardrobe, etc.

If the air in your office or house is so dry that you are putting up with the above issues, a humidifier is a must-have item. Nonetheless, of course, if you live in a humid climate, it will be unnecessary or even harmful.

The same thing happens if you leave your humidifier creates dampness beyond the suitable level.

3. What are the signs of excessive dampness?

As we mentioned above, a humidifier is useless and even negative if you live in a humid climate, or you use it improperly. So, you had better realize when the humidity is becoming superfluous.

The most straightforward method to do this is by using a hygrometer or buying a humidifier integrated with a humidistat to check the moisture level.

Otherwise, you can observe moisture or water accumulating and dripping on items in your house, such as glass surfaces of doors and windows, mirrors, furniture, wet and clammy floors, so on.

Other signs that may be a bit more difficult to detect include the emergence of mold, mildew, allergies, respiratory issues, etc.

4. Should I run my humidifier all the time?

This depends on the humidity in your room/house/office. When the air’s dampness reaches your desired level, you can turn it off. Anyway, most humidifiers are designed to run all day long.

Also, there are humidifiers that are smart enough to turn itself on/off when necessary.

5. How often do I need to replace filters?

Although most manufacturers suggest replacing the humidifier’s filter every quarter, it may even not last as long as that.

Depending on the volume of pollutants in the air and the water that goes through the filter, a filter can last for one to three months.

If your tap water contains a huge amount of mineral content and dirt, and the air is full of smoke, mildew, pet, so on, you should clean the filter and replace it more frequently.

Pay attention to apparent signs that tell you it is time to replace your filter such as bad odor, reduced performance, mold growth, etc.

6. Where should I place my portable humidifier?

It is out of question that you should put your humidifier in the places where you need it to work most. These may be your living room, your family room, bedroom, children’s room, or where there are many wooden items, etc.

While those are the most common and ideal locations, you should also take the coverage area of your portable humidifier into consideration. If it cannot affect a vast area, just place it in a small one.

7. What are the signs showing that I need humidifiers?

When you feel hard to breathe or suffer from itchy skin, nose bleeds, chapped lips, allergies, or other medical issues relating to dry air, it is high time you purchase humidifiers.

Apart from that, you can find wooden objects in your home too crispy or damaged due to dry air. Or simply your hygrometer indicates that the humidity level in your home is too low, you should also need the help of a humidifying machine.

8. Are humidifiers quiet or noisy?

While there are humidifiers that feature a “quiet”, “super-quiet”, “whisper quiet” operation technology (often ultrasonic models), there is no 100% silent model.

If you need quiescence, it is a good idea to purchase a humidifier with a night mode and several different speed settings.

Whatsoever, a humidifier should only be as quiet (or noisy) as an average refrigerator/air-conditioner.

9. How long can a 2-gallon humidifier run before I have to refill its tank?

Typically, a 2-gallon humidifier can run for around 12 – 14 hours consecutively before you need to refill it. However, this may depend on the settings that you configure it to run.

For example, if the appliance operates in the minimum setting, it can run for up to 16 hours. Meanwhile, at the maximum setting, it can continuously run for merely around 9 hours.

So, on average, you should fill your humidifier’s water tank twice a day, each time is 12 hours separate from each other.
