Facts about radon, mold, and moisture.
Mold
1. The Eliminator is attached to any standard foundation
vent, and then wired to a 120v source.
2. Optional de-humidistat is placed in center of crawl
space area.
3. When temperature in crawl space exceeds 50 o F
and/or when humidity exceeds de-humidistat setting,
the Eliminator is engaged.
4. Moist air and radon gases are pulled from crawl
space and replaced with fresh, outside air.
5. When thermostat or de-humidistat are satisfied, the
Eliminator is deactivated.
Typical installation
Radon
Radon is a radioactive gas that is considered to be a
health hazard affecting indoor air quality worldwide.
Radon gas is the second most common cause of lung
cancer in the United States. One in fifteen homes in
the U.S. has a high level of radon.
Mold
According to a study by the Mayo Clinic, nearly all
chronic sinus infections are a result of mold. Since up
to 40% of the air we breathe in the home can come
from the crawl space, mold in the crawl space means
mold in the home. The EPA recommends to keep
humidity levels in the crawl space to 40% –50% to
reduce the likelihood of mold formation.
Moisture
Excess moisture in a crawl space can have serious
consequences. Not only can it lead to mold formation,
it also increases termite potential and can increase the
potential for rot in floor joists, cross members, and sub-
flooring. Moisture level in wood should be less than
20%. In high humidity areas, that number can easily
exceed 30%. To maintain safe moisture levels, experts
recommend a plastic moisture barrier on the ground in
combination with a vent fan such as the Eliminator.
