What Humidifiers Do?

There are two primary kinds of humidifiers and these include warm mist and cool mist. To know the best unit for your house, consider the following:

Warm Mist Humidifiers

Several doctors recommend this kind of humidifier since its warm air could kill germs and viruses. Warmer air can help you breathe well and it lessens buildup of mucus. It also opens one’s respiratory passage.

Cool Mist Humidifiers

Since this kind of humidifier does not have an installed heating system, the air it produces is cool or room temperature. The reason why doctors could recommend this kind of product is that young toddlers or children can’t be scalded when touching or playing it. Cool mist devices could also be recommended if you or your child suffers from croup.

Those kinds of humidifiers add moisture to the room with the major difference being that cool mist device releases good room temperature air while warm mist devices release heated air.
