Humidity control tips

HUMIDITY CONTROL IN THE HOME

 

One of the leading causes of mold in warm humid climates is humidity.
Everyone knows that leaks causes mold and that leaks must be repaired as soon as possible  to prevent mold growth. However few take elevated humidity seriously, people will live with high humidity for weeks, months, or even years and think nothing of it. Yet it is humidity that causes a thin sometimes almost invisible layer of mold to grow on clothes in our closets, on furniture, and on walls ceilings, and floors.

This surface mold is sometimes referred to as mildew, microscopic analysis will reveal the presence of mostly Aspergillus, Penicillium, and Cladosporium and others. Culturing or DNA analysis reveals much of the powdery white mold to be Penicillium chrysogenum and the black colonies to be Cladosporium. My specialty is dealing with these very specific types of mold problems. The above mold identity observations are based on my own analysis and lab analysis of hundreds of samples.

To prevent such growths from spreading throughout your entire property and potentially covering all your belongings follow these steps:

1) CLOSE WINDOWS AND DOORS
Most importantly stop humidity at it’s source. Do not keep windows and doors to the exterior open excessively on warm humid days.

1) VENTILATE SHOWERS
Also in line with source control, ventilate bathroom air to the exterior during and for several minutes after all showers. After doing mold inspections and humidity investigations in South Florida for a decade I can safely say that outdoor air infiltration and showers are the two leading sources of humidity in homes in my area and likely yours as well.

2) SEAL ENTRAINMENT HOLES
Seal openings in AC closet walls and ceilings. You will not find this one in a book or any other source. I cannot find it anywhere but I can tell you without about that this one can and does cause humidity problems. Openings even a few inches across in an AC closet wall will allow the AC to pull humid air out of the walls. This humidity will then be free to circulate through your AC and through your property. Sure the Will remove some humidity but it can only do so much.

3) CHECK ON V.S. AUTO SETTINGS 
Set your thermostat to auto and not to on. This is another one of those tips that are not well known. Setting your thermostat to on will cause your AC to circulate humid air without drying it, this is obviously a bad thing. Setting it to auto will force the AC to dry and cool your air when it circulates it.

4) LIMIT FRESH AIR INTAKE IN HVAC SYSTEMS.
In commercial buildings introducing fresh outdoor air into your AC system can be beneficial, and even a building requirement, it dilutes indoor pollutants such as volatile organic compounds and body odor. However in warm humid areas outdoor air being pulled into the AC system will very often overwhelm the AC units ability to dry air and will cause condensation, humidity, and mold inside the system. Some of the buildings and homes with the foulest smelling mold problems are in such a condition because of the introduction of fresh outdoor air. This is truly a case of good intentions resulting in a very negative outcome.

Of course there are other factors to consider such as boiling foods, detached dryer vents, humidistat use, and improperly sized AC units. The above considerations however should cover most situations.  One other thing I did not mention is using a dehumidifier. These devices can be quite effective at removing humidity from your air but they do not solve the problem only mask it. It is almost always possible to cure the problem with a proper understanding of what is causing the problem.

Toxic Mold Syndrome

September 18, 2013

> Subject: Toxic Mold Syndrome?
>
> Message: I am concerned that I may have Toxic-Black Mold Syndrome.
>
> For the past 2 years I have experienced the following symptoms:
>
>

Question: Black discharges/grey spores in my phlegm—normal CT Scans

Answer: Spores of toxic and other household molds are usually around  2 to
10 microns more or less, thus you cannot see them in your phlegm.

Question: Sinus infections but tests have ruled out that possibility and not
a  chronic sinus issues

Answer: Over 90% of all sinus infections are caused by mold according to a
mayo clinic study a few years ago, it is thus very likely that your
infections start out as mold, typically a common mold called Alternaria
altanata. As the infection progresses it is taken over by bacteria in the
sinuses and the mold does not show up in culture because it is crowded out,
or because the lab only looked for and singled out bacteria during
culturing. You do not have to believe this mold inspector, A year ago at a
seminar I learned this from one of the doctors who discovered this mold &
sinus
infection link years ago.  This has been common knowledge among most doctors
for a few years but some have not caught on yet.

Question:> Illness prone with increased susceptibility to colds and flu bugs

Answer: This is a somewhat common and a possible clue that you may have
possible mold or other allergens, If you have allergy to mold, or if you
have
asthma, then you may develop allergy and asthma symptoms in moldy homes,
this
damages the protective mucous linings and some doctors and scientists
believe that this increases the chances of catching
cold. I have seen it to many times on mold inspections.

Question:> Chronic fatigue

Answer: I here about chronic fatigue from clients sometimes. I know of no
truly scientific
studies that support this, but if you do not sleep well because of allergy
or asthma, or if you are depressed on anxious over your overall condition
then depression, anxiety, or lack of sleep, might cause fatigue, I am
not a doctor this is not a medical statement it is just a common sense
theory and it is not my own but once again I read it from some scientific
studies.

Question:> Increased asthma symptoms–such as wheezing and breathing issues
> Allergy symptoms, tested but none positive

Answer: This is a very common and likely clue that you may have possible
mold or
other allergens, in fact mold triggers asthma symptoms in persons suffering
from asthma, and it increases a childes chances of developing asthma by
double
this fact is from a reputable study as well.

> Excessive Post-Nasal Drip
This is a very common and likely clue that you may have possible mold or
other allergens, in fact mold triggers allergic reactions in persons
suffering from allergy this is well known by al doctors.
>
Question: > All symptoms began when I moved into a new apartment, 2 years
ago.

Answer: Both happened at the same time, wow this is the best clue that you
may have
possible mold or other allergens in your condo.

Question:> The air system revealed that acrimonium was found.
What ? did your air system talk to you and tell you you have acromonium?
I can almost guarantee you have rodents or  roaches, releasing allergens and
making you sick, or you have dust and humidity that
causes dust mites, or mold releasing allergens and causing these problems.
Most likely you have mold.

Question: I also had a lung chest X-ray and it was normal.

Answer: Chest X ray will not show exposure to allergens or asthma triggers,
some x
rays show fungal infection.
>
Question:  > Do you think I could have Black Mold Syndrome?
>
Answer: No you do not likely have any Black Mold Syndrome. But at the same
time I
would bet you just about anything you have something releasing allergens,
most likely mold hidden
in your condo walls or AC.
You have been reading bias non scientific fear monger stuff online.
Stop worrying about toxic mold you are not likely being poisoned you are
more likely having allergic reactions to mold.
I do not care if you tested neg for some allergens, you may be allergic to
some
specific mold or allergen in your condo that you were not tested for.
Regardless of toxin vs allergen you still need help.

> Any additional information, help, or referrals would be greatly
> appreciated. Thank you for your help and time!

I have to say once again I am not a doctor you need to see a general doctor
for a
referral to a allergy doctor. This is not medical advice just guidance
telling you to see a good allergy doctor or mold inspector.
A knowledgeable doctors best advise may be to tell you to hire a good mold
inspector to find the problem.

Have an inspection done by a certified indoor environmental consultant or
certified indoor environmentalist who can find the problem if any, and who
can advise you or your landlord on how to have it professionally remediated.
for certified inspectors go to iaqa.org

Think about moving to another apartment if any mold problems are found and
not resolved.

Read only non bias mold info  written by epa,  centers of disease control, your
state health dept, doctorfungus.org, institute of medicine, etc. I know all the symptoms you described are blamed on toxic black mold, but people who want to make money off you after scaring you will blame everthing under the sun on toxic mold. In reality most everything you described sounds like allergy related reactions, in the real world toxic reactions are typically from eating toxic mold not breathing it in, but most people do not know this.
