I just found out that the humidity in my apt. gets low when the heater is on....it got down to like 50 deg. here the other day, so I turned it on for the first time....The humidity in 'the closet' was getting to around 40 and I don't do well without humidity....

i went it picked up two humidity units for about $25 each....one for my bedroom, one for the office/herp room. They seem to be doing really well.
