Who is Honeywell?

Honeywell is known to be one of the most respected and largest companies that focus on engineering and electrical technology. Moreover, the brand's history can be traced back to the end of the 19th century. With over 130 years of experience in the industry, Honeywell produces unrivaled top-of-the-line home appliances. It not only puts out great humidifiers, but it also has a wide range of products ranging from security systems to thermostats.

The brand carefully picks out the features that users would greatly benefit from and eliminates those that are highly unnecessary, thus resulting in the best products. Apart from manufacturing well-made products, Honeywell also stands behind their craftsmanship by offering a warranty on their humidifiers.

How Does Honeywell Compare to the Competition?

Installing a humidifier by Honeywell can be quite instrumental in combating various negative aspects of the environment, particularly in the cold months. Extremely effective and highly affordable, these humidifiers offer numerous benefits that greatly assist homeowners in establishing a healthy home environment. Honeywell outperforms many competitors for many reasons. These include:

Relieving dry and itchy skin

With the wonderful cold winter months come skin agitation, which can cause a series of uncomfortable and painful conditions like chapped lips and cracked skin.

Plus, such skin ailments can worsen for homeowners living in areas surrounded by insufficient moisture. However, a Honeywell humidifier adds the right amount of moisture into the air, efficiently helping to combat itchy and dry skin.

Creating a comfortable breathing environment

Pollution and cold weather can both cause extreme mayhem with the respiratory system, particularly if the winters are dry. As winter comes, flu and cold attacks become more common than ever. As a result, bitter air significantly weakens the immune system and aggravates the sinuses. Honeywell offers numerous humidifiers that can act as the remedy for problematic and disastrous winter air. With a Honeywell humidifier installed, you can enjoy a new level of protection from discomfort and illness.

Protecting your furniture

In addition to posing a threat to the wellbeing of homeowners, cold, dry weather also has the potential of damaging the interior of a household. The constant presence of frigid air causes wood to naturally shrink. Moreover, an inadequate amount of moisture can cause the wood to splinter and the paint to smear. These outcomes can ultimately add up to a hefty amount of housing repairs. However, with a Honeywell humidifier installed, you can add some moisture to the dry air that causes cracking woodwork and carpet shock.

Honeywell humidifiers are available in various sizes ranging from large to small. Each humidifier employs different methods and technologies for creating vapor for your house.

This Honeywell whole house humidifier has a flow-through design. Apart from its design that provides various benefits, the unit is quite feature-rich. Suitable for houses as big as 3000 square feet, it releases up to 16 gallons of moisture daily. Its flow-through design ensures that it stays free of microorganisms that are removed by draining and rinsing routinely.

If you want a small humidifier to adjust the moisture level in the air around you, the Honeywell HUL520L Mistmate is a good option. While it’s a little bigger than a personal humidifier, it can handle a space of roughly 150 square feet.

Honorable Mention:
Honeywell HCM350w

Honeywell HCM350B Germ Free Cool Mist Humidifer White


  • Easy to maintain
  • Large tank that is dishwasher safe
  • Doesn’t need to be cleaned frequently
  • Highly durable unit that can work for many years


  • Lid of the tank isn’t easy to clean
  • Makes noise even on the low setting

Our Review

To date, the HCM350w is one of Honeywell’s most loved humidifiers. With a 1.1-gallon tank, the unit is able to cover an area of up to 500 square feet. It is an affordable and robust cool mist humidifier that makes use of an evaporative system.

One of the greatest features of this unit is the UV light feature that can eliminate 99.9% of bacteria, mold, and germs. It also prevents them from mixing up with the water, thus ensuring that the mist is completely clean. Moreover, its self-regulating evaporative system reduces the risk of over-humidifying a room. So, you can use this unit without any worry around small children overnight.

Since it is an evaporative humidifier, it doesn’t leave a film of white dust when it is used with hard water. Another strong suit of the unit is its ease of use as well as the simple control. There’s just one dial that allows users to choose from three fan speeds. Plus, the tank is quite easy to fill thanks to the large filling hole. The large hole also means that cleaning the tank is simple. Lastly, the unit accompanies an easy-to-grip handle which makes it super easy to carry the tank.

Bottom Line

The patented ultraviolet technology of this unit helps to kill up to 99.9% of virus, fungus, mold, and bacteria in the water. Thus, the unit emits moisture that’s free from germs. Overall, it is suitable for medium and small sized rooms both.

Honeywell Cool Moisture Console Humidifier


  • Pushes a great deal of air out
  • Can humidify a very large area
  • Tank can hold up quite a large amount of liquid
  • Automatic shutoff feature adds to the unit’s security


  • Tends to rattle and vibrate
  • Honeywell does not have its own replacement filters

Our Review

Most commonly, humidifiers are designed to add moisture to only one room of the house. However, with this console humidifier, you can increase the humidity level of your whole house. This is a large unit that comes with dual tanks capable of holding three gallons of water. Moreover, it is rated to cover a space of up to 1900 square feet, which is more than what many portable humidifiers have to offer.

With its 3-gallon tank, this humidifier can work for up to 24 hours so you can enjoy the perfect humidity level throughout the day. In addition, this unit comes with a humidistat that senses when the moisture level in your room is low. Once the moisture level is up to where you want it to be, the humidifier stops; it’s just that smart!

Another important feature of this unit is Evaporative Technology. This unique technology blows the moisture off of a wicking filter, rapidly evaporating it into the air. With this technology, over-humidifying your air is impossible since the technology avoids adding in more moisture than the air can handle.

To keep the humidifier running, you’ll have to change the filters. Plus, the unit is easy to clean and can be simply done with a vinegar wash or additives.

Bottom Line

This is the ideal option for those looking for a whole house humidifier but don’t want to install anything on the furnace or water lines. Plus, its evaporation technology and the 3-gallon tank provides the ideal humidification for 24 hours.
