Basics

A Device that removes water vapor from the air, producing relitively pure Distilled Water
Most use a Peltier Module and are thus innefficient, yet also compact and simple
Most OTS do not have a "set relitive humidity" and simply remove as much as possible
Most HVAC units have some intigrated system
- Although not often VERY capable
User:Eric currently lives in florida and considers humidity control a borderline life support system (we have a statue of the inventer of refrigeration in the statue area of the congress building...)
