Buyer’s Guide

So, you are interested in buying a warm mist humidifier? It is not a difficult process, but it can still take a while to figure out which humidifiers are relevant to you. The last thing you want to do is waste time and money on warm mist humidifiers that don’t fill the needs you expected, so it is always a good idea to focus on spending a while doing your own research. Even if it extends your search time by 12 hours, you will get much closer to finding a good humidifier, even if it is only in the top 10 best options that you’ve found so far.

Tank Capacity

The tank capacity of all warm mist humidifiers (as well as cool mist humidifiers or units that can handle both) can directly affect how useful they are for their intended purpose. A warm mist humidifier that runs out of water in 12 hours is half as effective as one that lasts for 24 hours in terms of raw statistics since it needs to be refilled half as often and can usually run for longer without being interrupted. If you ask anybody what their 10 best humidifiers would be, they’d usually mention ones with a high capacity for this exact reason. There is also the fact that having to refill humidifiers is a hassle: every single one has to be refilled in some way eventually, but it is still a chore that can get annoying if it has to be done really often.

Mist Settings

The best mist humidifier for you will obviously be one that produces a warm mist, but this doesn’t mean a single set of details. The best warm mist humidifiers for one person might not even be in the top 10 best warm mist humidifier options for another. The same goes for any cool mist humidifier, ultrasonic humidifier, or whatever other features you are focusing on: all of them have specific settings they might offer that change how they work.

For example, some warm mist humidifiers also double as a cool-mist humidifier, including a cool-mist option that you can swap to at any time. Others might let you adjust the amount of warm mist created at the expense of emptying the tank faster. Either way, these features can change how humidifiers work while also making them more suitable for certain tasks or locations over others.

Cleanliness

A warm mist humidifier creates water vapor, but this warm vapor can sometimes be dangerous (the same goes for cool mist, too). If you have allergies or a weak immune system, this warm or cool mist can deliver bad bacteria right into your body, but there are ways to prevent this. For example, an ultrasonic humidifier like a Vicks warm mist ultrasonic unit cleans the internal tank, while the rest of the Vicks warm mist humidifier uses a filter to get rid of any bacteria in the water. Other designs will allow the tank to open up properly so that you can easily clean it without having to take apart the entire humidifier, which can be just as good of an option.

Is cool mist or warm mist better?

A warm mist humidifier is the superior option when you are cold or sick, whereas cold mist humidifiers are better when you are hot. That is really the only consistent difference between the two that most people will care about since all humidifiers still work in more or less the same way. Warm mist humidifiers work differently to cold humidifiers, and the tanks aren’t the same, but if you understand one, then you also usually understand the other. Choose based on your heat-related needs and current climate, since the wrong type of humidifier can easily make you even more uncomfortable.

What is the best warm mist humidifier to buy?

It is impossible to pick one product and say that it is the best on the market. All humidifiers can have differences, ranging from the tank, type of mist, ultrasonic technology, or even just the shape of the unit. You might like a Vicks warm mist humidifier, but another brand might make the best warm mist ultrasonic humidifiers you’ve seen: you have to look at humidifiers as individual units, not part of a brand.

Because of this, the “best” warm mist humidifiers vary from person to person. The best warm mist humidifiers for you might be different from the warm mist humidifiers preferred by somebody who lives next door since even one small difference can change which humidifiers are the most useful in each location or situation.

Conclusion

If you are still looking for details on the best humidifier available, you might need to start searching on your own. For every humidifier that doesn’t suit you, there is also at least one that will, and it is just a matter of taking the time to track down a humidifier that fills your needs properly. Be sure to use these reviews and this buyers’ guide as help, since there is a lot that can go into a humidifier, and it is not easy to know where to start if you’ve never had to buy one like this before. Whatever you end up choosing, the extra waiting and searching time will have been worth it!

Expert Tip

Keep your humidifier away from walls if possible: certain surfaces can get stripped by the warmth of the air, leaving the humidifier.
