What The Heck Does A Humidifier Do And Why Do I Need One?

Just in case the Internet hasn't sufficiently informed you, it's getting colder outside. And as the weather gets cooler and the air drier, you might consider purchasing a humidifier, which can alleviate some cold-weather ailments.

So, what exactly does a humidifier do?

There's more than one type of humidifier, but at the most basic level, the device emits water vapor into a space to increase the level of humidity. When used correctly, humidifiers can help to alleviate dry skin, chapped lips, nose bleeds and other pesky cold-weather conditions. It can even help to reduce some snoring!

Are there any downsides to humidifiers?

Humidifiers do more good than bad, as long as you clean them properly. Without regular care, a dirty humidifier could promote bacteria and mold growth.

You can monitor the indoor humidity of your home by checking this website, and looking for an increase in condensation, mold or insects in your home.
