either buy a humidifier, they start around 30 bucks but range to well above 200 just as well, and we are not really in the season for those now if you not happen to live down under so you have to check and shop around a bit i guess.
other method would to use passive vaporisation, so vaporise water from a jar basically get a rubbermaid box with lid and drill holes in for a or several wicks, the key is to create as much surface as possible and place it into air current
A bowl of water with an airstone in it. You can get a cheap air pump at the pet store for $3-4, and the airstone is about $1. This would be better than just a bowl of water, but not as good as a humidifier.
