What type of humidifier is good for pregnancy?

There are two kinds, such as warm and cool mists humidifiers. Your choice is a matter of preference. We’ve explained each of them to enable you to decide which you think is best.

Warm mist humidifiers

This type boils water, destroying germs before distributing the output. The mist it releases is considered highly safe and healthy due to the heating process that kills germs.

On the hand, occasionally, the hotter mist it releases can cause burns. Additionally, warm mist units consume more energy and may increase your monthly tariff.

Cool mist humidifiers

Ultrasonic or evaporative humidifiers are also known as cool mist units. They don’t heat the water, use vibration frequency, or an evaporative process to emit mist, depending on the type.

If you want to add moisture to a larger space, a cool mists humidifier is better and is friendly around kids.

You’ll pay less on electricity but spend more on buying distilled water because using ordinary tap water can lead to white dust settling in the home.

In addition, cool mist types require high maintenance, unlike their warm mists counterparts.

Humidifiers risks during pregnancy
