cool mist humidifier or warm mist?

[Damicofam6]

I currently have a warm mist but i have seen people say that cool mist is much better, the humidifier does not run directly into the cage so the heat isn't the problem I have just heard that warm mist may cause respiratory problems.

Warm water will be a perfect host for bacteria. Unless you plan on disinfecting it quite often, I'd stick with the cool mist. That's what I have and I use it primarily in winter when humidity levels need to be higher.

When you say "warm mist" humidifier do you mean a vaporizer? Does it heat the water to produce steam? That's what you don't want to use, as the water reservoir will sit and stagnate...and potentially support algae and bacterial growth. What is often called a "cool mist" humidifier is an ultrasonic type that produces a room temperature fog. Any humidifier can harbor algae and bacteria so you do need to clean them periodically. The cool mist types, used with either distilled, demineralized, or reverse osmosis water will tend to stay cleaner longer.
