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.
When indoor humidity exceeds 60%,
the home is more susceptible to
mold and mildew growth. TrueDRY
DR90 safeguards against excessive
humidity in the home year-round.
