I was pricing humidifiers today to put in my snake room, which is actually my garage. I'm going to need one since the heat is on the humidity is low. Anyway, some said "cool mist" and some said "warm mist". Does it matter which one I use? I'm assuming the warm one. Thanks in advance for any info.

I tried a cool mist unit and quickly exchanged it for a warm mist model. Since my entire snake room is heated I thought it made more sense to have a humidifier that complimented the heating system rather than fight it by adding cool mist. If a cold mist model is placed to near tanks I'd be afraid of creating a potential cold spot or draft. The only problem I've run into with a warm mist is mineral deposits accumulating and ruining the unit over time. I now use ultra-pure deionized and biologically pure water which is one benefit of working in a pharmaceutical analytical lab LOL. Since the average person doesn't have access to purified water use of clear vinegar to periodically clean the system helps prevent scale build up from minerals.

You want to make sure that the unit is disinfected often to prevent bacteria and othe nasty things from multiplying and then being spewed into the room. Even though the water is boiled in many brands, there are many surfaces that stay nice and warm, but are not subjected to temperatures high enough to kill everything off. Most manufactures recommend that the unit be washed with a bleach solution periodically. Also try to check out some reviews of the unit you wish to buy as many brands have mechanical problems and some companies have very poor customer service or get a failing grade in honoring warranties.

I definitely agree that bacteria, algae, and even fungi can grow if not contolled. My unit also has a UV bulb the water passes through to keep microbiological organisms from getting into the mist. An indicator light comes on as well to tell me when the bulb needs replacing.

The UV bulb will help kill bacteria as the water passes, but it will not stop anything from growing on the "cooler" surfaces where water will collect subsequent to the UV and boiling of the water including most of the plastic parts in the discharge area. Assuming you have a slant fin brand unit, be aware that these units are prone to break and their customer service as a rule is not very good.
I agree that this type of humidifier is better, but you still have to clean and disinfect it occasionally to prevent any spread of various organisms.
