There are a lot of options based on your specific needs- room temp and humidity, tank construction and set-up, tank temps and humidities. substrate, etc.
One quick and simple option is a basic 'warm mist vaporizer', about $15 at most department or drug stores, can run most of the day on a filling, and do not throw out cool mist that chills the habitat. It would be even better on a timer set up that ran it for a while every hour or so.
I just got one of them. Fantastic. Seems to me there is a small element inside that gets laser hot so it seems to flash boil the water that contacts it, but doesn't heat up all the water. Seems it boils the water so fast and on a small scale that there is little to no heat transfer to the main body of water. Efficient little sucker. You control the amount of steam by controlling the salinity. More salt = more steam... to an extent of course.
I guess I'm down to deciding between the sunbeam and vicks. both look good. may check them out this weekend. hopefully wal*mart has them both. we'll see.
I do like the habba mist one for retiles, but it's so much more. What's the difference between a reptile mister and a humidifier?
But as far as the difference between reptile humidifier and human humidifier?
Looks, and price. Mostly. There's a lot of 'reptile' accessories that have been in people pharmacy's for decades. Typically, the human made alternatives are built to a higher standard with more safety features (See: Heat mat/Heat pad). Calcium is the same way, get it at the pharm, and grind your own. There's almost always cheaper and easier ways for the thrifty person with access to large reptile and pet forums.
I should have thought about the question when I asked. Ha. It's self explanatory. Guess I'm checking target tonight after I run to the pet store. they're side by side in the complex, and I may have time to spare before my bf gets off.
