What to Pay attention to When Choosing the Best Humidifier for Baby

When it comes to having a humidifier in your baby nursery room, the biggest benefit is that you will protect your baby from the dry air.

This is especially important during the winter, when, because of heating systems, the air in your home becomes dry, and without its natural moisture, which is extremely important to have for the newborn’s, proper health development.

However, before making the final choice, there are a few things to consider.

Warm Or COLd Mist HUMidifier?

There are both cons and pros to each type of humidifiers. For example, warm humidifiers produce a warm mist, which results in pathogen-free air, and they are much easier to maintain.

On the other hand, they tend to get hot and dangerous for touching, and if spilled, your child can potentially burn itself on the hot water.

The cool mist humidifiers are designed specifically to prevent having dangerous situations as they produce cool mist and do not heat up.

However, they need to be regularly cleaned and maintained, or they can start producing mist with pathogens such as mold and other microorganisms, which your child can inhale.

Ultrasonic Or Evaporative humidifier?

The ultrasonic units take up less space, use less energy thus are more effective, and are quieter than evaporative models.

But, they are more expensive, tend to spread the white “dust” around the room because they don’t use filters, and are more prone to breaking down.

On the other hand, evaporative humidifiers are more durable, don’t produce the white dust because they use filters.

But, they need more energy, therefore bigger electricity consumers, need more space, and are noisy because they use and the high-powered fans to move the air through the machine.

HIDDEn costs of 

With cool mist humidifiers, since there is no water heating element in the equation, you can save up some money in the long run on account of the electricity bills.

But, unlike with evaporating models, ultrasonic ones need much more maintenance, and it’s better to use distilled water to avoid the dreadful white dust, and that water costs.

On the other hand, evaporating humidifiers are not that demanding, but they need regular filter replacing, and they tend to “eat” more electricity, which all adds up to a serious the final cost.

So, in the long run, ultrasonic models will come with less hidden costs, but they need more attention.
