UNDERSTANDING HUMIDITY
Humidity can be puzzling. It cannot be seen, heard, touched,
smelledortasted. Many peopledo notunderstandwhat a humidi-
fier willor will notdo.
Probablythe best way to judge whetherthe humidityis too high,
too loworabout dghtis towatch yourwindows.If they are heavily
fogged you mostlikelyhavetoo much.Ifthere is no moistureon
them at all, especiallyin the comers, you have too little.(NOTE:
Moisturewill notnormallyformon thermopaneor whenstormwin-
dowsare used.)If there issome moisture in the windowcomers
andalongthe edges,the humidityis Justaboutright.This isa good
rule of thumb, if you do not have an expensivepiece of testing
equipment.Yourcomfort is anothergoodcheck.
TYPICAL QUESTIONS ASKED
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.
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.
2. How can I best check my home's relative humidity?
First give your humidifiertime to build up the humidityto an
acceptablelevel. Instrumentsare availabletomeasurerelative
humidity,but from a practicalstandpoint,your comfortis the

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 out the home has become. In some
cases, it may take a week or more.
