UNDERSTANDING HUMIDITY

Humidity can be puzzling. It cannot be seen, heard, touched,

smelledor tasted. Many peopledo not understandwhat a humidi- fier willor will not do.

Probablythe best way to judge whetherthe humidityis too high, too low or about dghtis towatch yourwindows.If they are heavily fogged you most likely have too much. If there is no moistureon

them at all, especiallyin the comers, you have too little. (NOTE: Moisturewill notnormallyformon thermopaneor whenstorm win- dows are used.) If there is some moisture in the windowcomers and alongthe edges,the humidityis Justaboutright.This isa good

rule of thumb, if you do not have an expensive piece of testing equipment.Yourcomfort is another good check.

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.

2.How can I best check my home's relative humidity?

First give your humidifiertime to build up the humidityto an acceptablelevel. Instrumentsare availableto measurerelative humidity,but from a practical standpoint,your comfortis the best guide.You cannot depend on table top or wall hung dial 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.

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 order to determinethe safe relativehumidityfor homes ex- posedtovadouslowoutsidetemperatures,NESCA* conducted

tests and publishedrecommendedhumiditylevels for various outdoortemperatures.These are shown in the chart.These levels help preventdamage to your home such as water run- ningdown the wallsor even buildingup insidethe walls.

The safe indoor relative humidity percentage is not a fixed num-

ber but will increase or decrease as the outdoor temperatures dse or fall.
