Pros and Cons of Dual Mist Humidifier
Well, if you are convinced about using a warm and cool mist humidifier in your home/room, you should quickly check about its advantages along with very few disadvantages.
The Pros:
✓ Comes with all the essential features:
The cool and warm misting humidifier comes with all the essential features (generally more than single mist units) such as auto shut off, low water indicator, humidistat, etc.
Also, it features smart modes (like auto mode and sleep mode), which is usually convenient for people who want to switch “On” their humidifier and forget.
✓ More versatile and good for all seasons:
With its unique versatile features and ability to produce either warm or cool-mist, this humidifier can make the temperature ideal both in cool and hot climate conditions.
You can, therefore, use it in all seasons (summer, winter, spring, and fall) to keep all your allergies at bay.
✓ Effective in providing better healing benefits:
As you can switch between the two modes (as per the atmosphere and your body needs), it assures that you ease all your breathing and skin problems very fast.
This type of humidifier is also good for the baby as it provides better sleep at night with its excellent features and options to select cool or warm mist.
The Cons:
The major drawback I can find with these types of humidifiers is it’s a bit expensive.
As it comes with a range of versatile features and sophisticated technology, the money you pay upfront when buying – will be more.
But in the long run, as you can enjoy dual benefits, we don’t think it’s an expensive buy.
If your family needs to buy another unit due to a change in season, investing in a dual mist rather makes sense and seems to be a much more profitable deal.
Using aromatic essential oil in these humidifiers is also not recommended in these models.
If however, you wish to use them, do check with your manufacturer and specific model if it allows you to do so.
Do not forget to clean your unit often, mainly when you use it regularly.

Should You Put Hot or Cold Water in Your Humidifier?
The air quality inside your home can be significantly affected by the temperature.
This means that the temperature of the water you put into the humidifier may have a considerable effect on the quality of the indoor air.
While most people tend to put cold water in their humidifiers on hot days and warm water in on cold days, the truth is that you may be best served by always putting in cold water.
Let’s see below – why?
It may seem counter-intuitive to some who only see the mist rising from a humidifier as hot.
But the truth is that cold water is recommended for most humidifiers for several good reasons.
It not only helps in dry conditions but also provides health advantages to those who want better indoor air quality.
What follows are just a few of the reasons why cold water should be the choice.
Fewer Microorganisms:
The differences between hot and cold water are more than just temperature.
Hot water contains more substances compared to cold water, such as the following;
- Mold
- Bacteria
- Minerals
The bacteria and mold are present because they have the minerals to cling on to and grow.
In cold water, the lack of minerals makes it far more difficult for mold and bacteria to gain a foothold.
By putting cold water in your humidifier, you can keep it from becoming a harmful source of harmful microorganisms.
Plus, that prevents specific issues from developing in your humidifier, which may shorten its life.
It’s Safer:
Accidents can happen to anyone, but with kids, the danger of hot water becomes more pronounced.
This is because children may not understand hot steam’s effects until exposed.
Plus, if the humidifier breaks and spills hot water, that may result in scalding or even a serious burn.
Given their curiosity and lack of experience, having hot water inside a humidifier represents an unnecessary risk.
Better to be safe and use cold water, which will not harm them.
Easier Breathing:
The FDA has determined that a cool-mist from a humidifier is actually better for breathing compared to a warmer mist.
This is because the cold water shrinks the nasal passages allowing for easier breathing. A warm mist swells nasal passages, making breathing more difficult.
Besides the above, there are other advantages as well to using cold water, but the bottom line is that it simply is better overall compared to hot water.
The advantages of using cold water are that you can run your humidifier safe, knowing it will last longer, not spread bacteria or mold, and not present a danger to the children or anyone else in your home.
Choosing to put cold water in your humidifier offers several advantages no matter the season.
In addition to regular cleaning, you should ensure that the cold water you put in is pure or close to pure to prevent the buildup of harmful microorganisms in the humidifier itself.
