Which’s better? Cool mist vs warm mist humidifier for babies

Cool mist vs warm mist humidifier for babies

Without going into technical jargon, a humidifier works by breaking down the water into tiny droplets (ultrasonic vibration) or by boiling water to form vapor (warm mist). It then disperses the tiny droplets, or the mist into the air that we breathe.

A humidifier is a very useful appliance when you are looking to get through winter. However, you would rather buy the right thing and choose it carefully so that you can keep it for a long time.

Cool mist humidifier: Good for the respiratory health of the baby

That is right, a cool mist humidifier is one of the best appliances to buy if your baby has sinus problems.

When the moist, cold air hits the membranes of the sinuses, they contract. This gives more room for air to pass through.

The way that cool mist humidifiers are designed is such that they have a wick that absorbs water. The fan then sprays the water through the filter, creating a smooth mist that is then spread throughout the room.

You may fear that this appliance will be noisy, but that is not the case. I mean, there is some noise, but it is what is referred to as white noise. Your baby will sleep right through the noise.

When you are considering cool mist vs warm mist humidifiers for babies, safety is always at the top of your mind.

If you have a toddler, you know how they move around fast. Get a cool mist humidifier because it is safer for the baby’s room. I mean, there are no parts to get hot and burn the baby.

A cool mist is easier to inhale than a warm mist. It has a softening effect on the throat, just the thing you would like to do to prevent the occurrence of a sore throat.

If you have a larger room, a cool mist humidifier would be much better. You see, when you have a warm mist humidifier, the warm mist can cool down before it reaches the furthest end of the room.

You will also save more money on energy bills than you would with the warm mist humidifier. OK, it could be just a few dollars, but hey, any money that you save is good money.

Warm mist humidifiers: good for indoor allergens and bacteria

From the section on cool mist humidifiers, you must think that warm mist humidifiers are no good. However, depending on the circumstances, you have to buy a warm mist humidifier for your baby’s room.

But first, a peek-a-boo into how a warm mist humidifier works…

This humidifier is going to boil water, and then it will release it in the form of mist into the room. It operates silently since there is no fan involved.

In the process of boiling water, the humidifier kills all the bacteria in the water. Thus, for your baby’s room, you can be sure that your little one is breathing in a fine, healthy mist.

Just as happens in the cool mist humidifier, a rotary disk moves fast, cutting the hot water into a fine and smooth mist.

This, in turn, is dispersed through the mist so that your baby can breathe it. The temperature will be higher than that of the cool mist humidifier.

If you think the water from your taps is not free of bacteria, it is better to use a warm mist humidifier in the baby’s room. It is pretty easy to carry out a test to determine the quality of the water that you use at home.

A warm mist humidifier also keeps the baby’s room warm

You need not worry about heating the baby’s room if you are using the warm mist humidifier. As it disperses warm mist, it will also keep the room warm.

It is the best humidifier for a small room during the winter. No one wants to inhale ice-cold air, and in winter, your air can be quite cold.

But the warm mist humidifier is not all glamour. There are some downsides to think about. One of them is that the tank requires to be cleaned more frequently than that of the cool mist humidifier.

Cool mist vs warm mist humidifier for babies: Pros

There are many benefits to using a warm mist humidifier or a cool mist humidifier in a baby’s room. There are a few disadvantages too, but you know when the pros outweigh the cons, you have a good product.

Cons for the best dehumidifier for baby

And feel good about yourself.

However, all is not done. You see, humidifiers need to be handled with care. If you are not very keen, they can cause more harm than good.

Since the work of a humidifier is to increase humidity, this can create a good atmosphere for indoor allergens to thrive.

Talking about indoor allergens, one of the most sinister of them is mold. It grows on walls, especially in the dark corners that you hardly reach when cleaning.

Mold can grow inside the water tank of the humidifier. It can cause respiratory problems. It can also cause asthma. Now, you can be sure that you do not want that to happen to your baby. That is why you must only use a humidifier when necessary.

Mold poisoning is another serious condition that you do not want anywhere near your baby. Unfortunately, mold spores are not visible.

Note that mold can only harm your baby if you do not clean the humidifier very well. You should do the cleaning in a solution that has 10 percent bleach.

Another thing that you have to consider is the cost of running the humidifier. It is a small addition to your energy bill, one that you hardly notice, but an addition all the same.

The warm mist humidifier can cost more to run at the end of the month since it boils water, thus spending more energy.

A warm mist humidifier means there is boiling water involved. In that case, you would need to be extra careful because hot water poses a danger to your baby. A spill would be nasty.
