UNDERSTANDING HUMIDITY
Humiditycan be puzzling. It cannot be seen, heard, touched,
smelledortasted. Many peopledo notunderstandwhata humidi-
fier willor will notdo.
Probablythe best way tojudge whetherthe humidityistoo high,
too loworaboutdghtistowatch yourwindows.Ifthey are heavily
fogged you mostlikely have too much.Ifthere is no moistureon
TYPICAL QUESTIONS ASKED
themat all, especiallyin the comers, you have too little.(NOTE:
Moisturewill notnormallyformon thermopaneorwhenstormwin-
dowsare used.) If there is some moisture inthe windowcomers
andalongthe edges,the humidityis Justaboutright.This isa good
rule of thumb, if you do not have an expensive piece of testing
equipment.Yourcomfort isanothergoodcheck.
1. Why do moisture requirements vary from home to home?
Requirements depend on the amount and dryness of air to be
humidified. The larger and more loosely constructed the home,
the greater the quantity of moisture required.
2. How can I best check my home's relative humidity?
Firstgive your humidifiertime to build up the humidityto an
acceptablelevel. Instrumentsareavailabletomeasurerelative
humidity,but from a practicalstandpoint,yourcomfortis the
bestguide.Youcannotdependon table top or wall hungdial
gauges.
3. How long will It take my humidifier to build up the
humidity In my home?
Much depends on the outside temperature, time of year, home
construction, and how dded outthe home has become. In some
cases, it may take a week or more.
4. What are some of the common things that cause higher
than average air leakage In the home, therefore causing
low humidity?
A. Jalousie windows
B. Open fireplace dampers
C. Cracks around windows and doors
D. Open doors and windows
E. Unusually large attic or foundation vents
F. Range hoods and bath fans
5. What else causes static shock besides low humidity?
Some types of carpets tend to create more static than others.
While the proper humidity level will reduce the static level, it
may not eliminate static entirely.
6. What Is the safe humidity level for my home?
In ordertodeterminethe safe relativehumidityfor homesex-
posedtovadouslowoutsidetemperatures,NESCA*conducted
