Honeywell has been and still is one of the top household appliance manufacturers worldwide.

For more than a decade they have produced top-of-the-line products that impress with longevity, quality, and ease of use.

They are known for many, many lines of products, but their air quality solutions for homes truly set them apart from their competition.

And this is, why we have decided to take a closer look at their humidifier line.

We have put their most popular products to the test, have tried and measured, and had a look at the gritty details for you. And now the results are in — here is our list of the best Honeywell humidifiers currently available:

Honeywell HCM350W Germ Free Cool Mist Humidifier

Q: Why do I need a humidifier?

Basically, too dry air can lead to a whole lot of problems. Your mucous tissue can dry out, making it easier for viruses and bacteria to enter your body; your eyes can become dry and itchy; as can your skin; headaches can become more common; … The list is endless, and none of the items are particularly pleasant.

A humidifier adds moisture to dry air and alleviates all of these problems – and more.

Q: Why does my room air get too dry anyway?

This, typically, is a matter of climate and season.

In winter the air is drier than usual. Add in the simple fact that we all somehow heat our homes and tend to air them less, and here’s your answer.

Q: Which humidifier is the right one for me, then?

That entirely depends on your preferences, intended use, and the size of the rooms you need to humidify.

Generally, you will have to make a choice between a few factors:

  • cool vs. warm mist (neither one is particularly “better”, but warm mist tends to soothe more when you are battling a cold and is also usually the option that can be used in combination with essential oils and inhalants)
  • filter or no filter (i.e. follow-up costs or not)
  • do you need white dust control, a way of dealing with bacteria in water, etc.?
  • suitable for large or medium or small rooms
