What
you should know about Mold
Mold, mildew, and fungi are all terms
generally used to describe a group of diverse plants which appear as
woolly or powdery growth. They have been recognized as an allergen
for over 100 years. Mold infestation is mentioned in the Bible in
Leviticus chapters 11-14.
Molds are everywhere, indoors and
out, in every type of climate, and in every social and economic
condition. They grow in places we would not expect. They are elusive
and will be more prevalent at different times of the day or night
depending on the type of mold. A single mold can germinate and
produce hundreds of thousands of airborne spores in 4-9 days.
Surveys have shown that high mold and
pollen counts frequently occur at the same time of year. Hay fever
symptoms may be caused by mold rather than pollen.
Mold needs moisture, food, which can
be any organic matter, and preferably warm temperatures. Relative
humidity below 40% discourages mold growth.
Molds are found in soil and in
decaying leaves, straw, grains, and wood. Any contact with these
things can expose you to mold. Mowing the grass; raking leaves,
working in the soil, working in a garage, barn, hay field, or grain
storage areas, cleaning out pet litter and sleeping areas, or
cleaning your closet can bring on symptoms associated with mold
allergy.
Lifestyles
That Increase Mold Counts
Poor housekeeping practices - dirty dishes and food left around the
house, trash kept in the house in cans or compactors, dirty clothes
lying around, and infrequent housecleaning-can all increase mold
growth.
The use of ceiling fans in lieu of
air conditioning can increase mold levels in homes. Higher
thermostat settings mean the air conditioner operates less so
humidity is not removed from the air.
Inefficient
Filters
Inefficient filters allow dirt to accumulate on coils, the drain
pan, and duct work. This dirt becomes "food" for mold. Washable,
electrostatic filters which contain media treated with an
anti-microbial inhibitor are preferred and have proven effective in
reducing mold levels in homes.

How
To Locate Mold
1. A gravity mold test can be done in the rooms you suspect have
high mold counts.
2. Inspect walls, ceilings, carpets,
windowsills, drain pan, ductwork, vents, bathrooms, and wall board
for any darkened or discolored areas.
How
To Reduce Mold Exposure
1. Decrease moisture and the
food source for mold on all surfaces.
2. Use a high performance
electrostatic air filter in the central air system.
3. Remove items on which mold
can grow from the bedroom.
4. Use a room air purifier in
the bedroom.
5. Drain and ventilate areas
under and around the house.
6. Clean and maintain central
air system.
7. Use air conditioning to
reduce humidity.
8. Use a dehumidifier to keep
relative humidity below 40%.
9. Frequently use a HEPA
vacuum cleaner on carpets and furniture.
10. Clean
visible mold from surfaces using Safety Clean. Treat cleaned
areas with X-158.
11. Remove moldy carpet.
12. Ventilate and put lights
in closets.
13. Keep shrubs and grass
trimmed from around the foundation of the house.
14. Wear a mask when doing any
activity that could expose you to mold spores
