So, you’ve determined that your interior air needs more moisture. Now it is time to buy a humidifier.
If you truly want to solve your dry air issue all over the house, then you need to buy a central humidifier, which hooks onto your HVAC system. For more portable applications, you will choose between cool mist, warm mist and ultrasonic types of humidifiers.
So what type should you choose: cool mist, warm mist or ultrasonic?
Your physician might have a recommendation for you.
If not, here is a short guide to help you make the choice that is right for you and your family.
Whatever type of humidifier you go for, make sure that it is not too powerful for the room you put it in. Otherwise you can end up with condensation in the room, which can ruin wallpaper and produce a fertile environment for bacteria and mold. Buying a model with a built-in humidistat can prevent this problem. It will turn off the machine when a sufficient humidity level has been reached.
No matter what type of humidifier you buy, it will need regular cleaning and possibly changes of filters. A solution of nine parts water to one part bleach is recommended in most cases to kill any pesky bacteria.
