About the TrueDRY DH150 Dehumidifier
The Honeywell TrueDRY DH150 ensures the home is maintained at proper humidity levels through its high perfor-
mance and efficiency.
Benefits
• Removes up to 150 pints of water from the indoor air.
• Can be ducted for whole-house humidity control, or operate
unducted to address moisture problem areas such as an attic or
crawl space.
• Easy access panels makes service quick and simple.
Maintaining Ideal Humidity
Dewpoints 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 TrueDRY is installed properly, your cooling
equipment may not run as much because dehumidified air feels cooler
than humid air.
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.
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 DH150 safeguards against exces-
sive humidity in the home year-round.

Conditioning Engineers (ASHRAE).
