Maintaining Ideal Humidity

Dew points and relative humidity (RH) affect the way your
body senses heat. Higher humidity levels cause the air
to feel much hotter than the actual temperature. When
maintained properly, your cooling equipment may not run as
much because dehumidified air feels cooler.
Ideal humidity is defined by industry experts* as being
between 40-60% on an average annual basis.
WHAT THE AIR FEELS LIKE
HOW HOT THE HEAT-HUMIDITY COMBINATION MAKES IT FEEL.
EXAMPLE: AIR AT 90ºF WITH 50% RH FEELS LIKE 96ºF TO THE HUMAN BODY!
SOURCE: TEMPERATURE - HUMIDIY INDEX WAS DERIVED BY R.G. STEADMAN, JOURNAL OF APPLIED METEOROLOGY, JULY 1979.
When indoor humidity exceeds
60%, the home is more susceptible
to mold and mildew growth. DR90/
DR120A3000 safeguards against
excessive humidity in the home year-
round.

and Air Conditioning Engineers (ASHRAE).
