8 Best Humidifiers in 2021 (and Why They’re the Best)

If you’re struggling with static electricity, chapped lips, dry skin and a scratchy throat especially during winter, a humidifier can help.

Cold air doesn’t hold much moisture like warm air does so the colder it gets, the more the humidity levels drop and the more uncomfortable you feel.

The best way to balance it all out is by investing in a humidifier to prevent the harsh effects of low humidity from affecting you and your family.

If you’re on the prowl for a good quality humidifier, then you’ve come to the right place. We’ve covered the 8 best humidifiers on the market, basing our selection on performance, features, customer experience, durability and overall quality.

The second part of this article covers everything you need to know when buying a humidifier as well as how to choose the right one for your specific needs.

Types of Humidifiers

Before we start, let’s take a quick look at what exactly a humidifier is.

A humidifier is an electrical appliance that increases humidity in a room or an entire building by putting moisture back into the air. It does this by emitting water vapor into a space, which increases the humidity levels and relieves dryness. There are five different types of humidifiers including the following:

  1. Central humidifiers: these are hardwired into the heating and air conditioning unit of your home and hooked up to your plumbing, humidifying your entire house at once.
  2. Evaporators: this type of humidifier uses a fan to circulate humidity in the room. It doesn’t generate heat and is ideal for homes with little children and pets. 
  3. Impeller humidifiers: these throw water at a diffuser by using a rotating disc. When the water hits the diffuser, it breaks into miniscule droplets that permeate the air.
  4. Steam vaporizers: these humidifiers use electricity to power their heating element, boiling water and creating steam. Before the steam leaves the machine, it cools down and then enters the air.
  5. Ultrasonic humidifiers: this type of humidifier uses a ceramic diaphragm that vibrates at an ultrasonic frequency, creating water droplets. These droplets silently exit the humidifier in the form of a cool fog. Some models use a fan to get the mist out whereas others are built without a fan and are mostly for personal use.

Each of the humidifiers we’ve reviewed below fit into one of these categories. The type of humidifier you select should depend on your specific needs and budget. With that said, let’s get into the reviews of our top 8 humidifiers.

Honeywell HCM350W Germ Free Cool Mist Humidifier

as of February 13, 2024 2:03 pm

The Honeywell HCM350W Germ-Free Cool Mist Humidifier is one of the most popular humidifiers on the market. It’s quiet, easy to use and designed for large rooms from 500-800 square feet. It falls into the evaporative category of humidifiers.

One feature that we really liked about this is the UV light, which kills up to 99.9% of fungus, mold or bacteria in your water. Also, the device features a wicking filter, which removes hard water minerals like calcium and magnesium. This makes it safe to use with hard water, as it doesn’t allow the minerals to enter your air and leave white mineral dust, as most other humidifiers do. This means that even if your water is unfiltered, the pathogens in it will be killed and the minerals removed before the water is dispersed into the air.

What makes it stand out from the rest is how easy it is to maintain and clean. Its water tank has a wide opening that’s big enough to fit your hand inside for easy manual cleaning and both the tank water tray are dishwasher safe, provided you place them on the top rack so all the corners get cleaned as well.

The Honeywell Humidifier features a built-in fan which makes a low buzzing noise when operational. This can be distracting if you prefer total silence at bedtime.

What We Liked:

  • Kills germs
  • Dishwasher safe
  • Affordable
  • Has a cooling fan
  • Improves air circulation
  • Can be used with hard water
  • The device is energy saving

What We Didn’t Like:

  • The bottom tends to detach easily, causing spills
  • White background noise can be distracting

It also has a large coverage area of up to 3,600 sq. ft, making it a powerful option for humidifying your entire household.

The device is portable and easy to use. We were impressed by the digital humidistat this model features, which can easily be set to automatically maintain the level of humidity in your home. The system also has the safety feature of shutting off when the air has reached the desired humidity level or if the tank is empty. This means you don’t have to monitor the system once you’ve switched it on. 

The unit is easy to clean since the side-mounted water tank is removable. However, replacing the filters can be costly and the design of the unit could use some work since it’s not as attractive as most of the other products on the market.

Humidifier vs diffuser

Pros and Cons of Using a Humidifier

Humidifiers come with more benefits than disadvantages but if you’re not sure about buying one, weighing the pros and cons might help you make up your mind. Let’s take a quick look at the possible pros and cons that come with purchasing a humidifier.  


  • Kills germs – It makes your home less conducive to germs that tend to thrive in dry air. This can reduce colds and flues, especially during winter.
  • Relieves dryness – Humidifiers add moisture to the air which relieves dryness and issues associated with dry air.
  • Nourished plants – It keeps your plants happy and hydrated as plants need more than 23% of humidity in the air to thrive.
  • Furniture – Proper humidity in your atmosphere can mean longer life for your furniture – fixtures and wooden furniture can suffer from being in an environment that’s too dry. A humidifier could help with that.
  • It provides comfort – Humidifiers help relieve symptoms associated with dryness in the air. These include irritated sinuses, eyes and skin, and other similar conditions.
  • Static electricity – Humidifiers can reduce static electricity in your home, which can prolong the life of electronics.


  • Condensation – If the humidifier runs too long or is on the wrong setting, it can increase the humidity levels too much, resulting in condensation. Condensation can trigger the growth of bacteria, mold and dust mites in your humidifier.
  • White dust – Some humidifiers disperse a very fine, white dust which is the result of mineral deposits and other contaminants in your water.
  • Risk of burns – There is always a risk of getting burnt when using warm mist humidifiers which boil water so if there are small children in the house you can keep it out of their reach or go for another option.
  • Can cause bacterial growth – This is mainly if your humidifier isn’t cleaned out as regularly as it should be. Bacterial growth can promote colds and coughs so remember to keep your unit clean at all times.
  • Filter replacements – Humidifiers often come with filters which remove the contaminants in your water. however, replacing filters can be expensive.

Key Considerations When Buying a Humidifier

With all these benefits, buying a humidifier makes a lot of sense for any home, especially during winter conditions. Here’s what you need to consider when purchasing.

  • Type of Humidifier

We’ve discussed this at the start of the article but here’s an infographic with a quick recap:

As we mentioned in the start, there’s no right or wrong answer to which type of humidifier to get. It depends on your specific requirements and budget.

  • Size

The size of the humidifier depends on the size of the room you’re planning to use it in. if you’re looking to humidify a room up to 1000 square feet, you might want to go for a console humidifier. These are larger units that stay on the floor and have large-capacity water tanks. They require less filling than portable humidifiers.

Portable humidifiers on the other hand, have small water tanks and need to be refilled more often. They’re not that expensive and can easily be kept on your tabletop, nightstand or desk.

Whole-house humidifiers attach to the ductwork of your home, adding humidity throughout since they have the ability to handle spaces larger than 1000 square feet. These are connected to the plumbing of your home so you don’t need to refill the tank. They’re also the most expensive and will require professional work to get them into the system.

  • Humidistat

This is an important feature to have in a good-quality humidifier. The humidistat monitors the level of humidity in your room and turns off the unit automatically when the moisture level in the air hits the set target.

Although this isn’t a vital feature, it makes things a lot easier when it comes to operating a humidifier. It also helps with preventing excess moisture in the air that can lead to breeding of bacteria and fungi. Over humidifying your home is another problem and can be avoided by a humidistat.

  • The Capacity of the Water Tank

The size of the humidifier you select is closely related to the capacity of the water tank and affects how often you need to refill it. If you want the unit to run all day or all night without interruption, make sure you go for a model that comes with a large capacity.

It’s also a good idea to check whether the tank is removable since this allows for easy filling. If it’s not, you may have to bring water to the unit with a jug or a pitcher, which can be a hassle.

  • Auto-Shutoff Feature

There are lots of humidifiers available on the market with the auto-shutoff feature. This is extremely important if you plan to leave the unit on for long periods of time, since it will switch the humidifier off in case it runs out of water. This is a useful feature that can prevent the unit from burning out.

  • Demineralization Cartridge

If you live in a hard water area, you might want to consider getting a humidifier with a demineralization cartridge. The filter will trap the minerals in your hard water and prevent them from being sent out into the air as white dust which can be a nuisance and cause respiratory issues.

  • UV Filtration

Some humidifiers feature a UV light that eliminates bacteria, mold and pathogens that can breed in the humidifier’s tank. This is a convenient feature since it will keep you and your family safe from microbial related health conditions.

  • Air Filter

If you suffer from allergies, opt for a humidifier with a filter that will clean incoming air. Air filters are great for trapping dust, pollen, mites and dander that can pass into the humidifier and be sent out into the air.

  • The Mist

There are two types of mist: cold and warm which need to be taken into consideration when choosing a humidifier.

Warm mist humidifiers aren’t recommended for use if you have children in the house since they can pose a risk of getting burnt.

Cool mist humidifiers make your room feel damp or cool initially and are safe for use around children.

Both types of humidifiers are highly effective at adding moisture to the air as well as easing sinus and respiratory discomfort so in terms of comfort doesn’t exactly matter which one you choose.

The Bottom Line

Humidifiers offer many benefits, especially when you’re suffering from symptoms of dryness, but they do require a little bit of attention and ongoing maintenance. However, they come with a range of benefits that far outweigh the disadvantages.

By following a few commonsense steps, you can ensure that your humidifier performs as expected and lasts for a long time.
