Jim,

I don't have AC. I've got a small humidifier unit, but only run it in 
the winter and then in the bedroom and not my office. I've had the 
CIS up and running for about a year and am just getting ready to 
re-fill the bottles.

I tend to keep the temps in the house cool; windows open in the 
summer and mid to upper 60's in the winter. Inside RH probably tracks 
with outside RH. Currently 43% -- I used to live in the Midwest and 
DC, so I tend not to pay much attention to humidity now <g>.

I can't tell if there are any deposits in the K tubes. I did have one 
clog when I set-up the CFS that took probably 50 cleaning cycles to 
clear. It may have been the K position, but I don't remember for sure.


Kevin
