Air Movers Ineffective At Drying Wet Carpeting
Air movers, fans and other drying techniques are generally not effective in drying carpeting. Biological growth will occur within 72 hours. The infrared image above shows wet areas around the air mover after 2 days. Mold and bad odors will result causing adverse health conditions in the home or building.
Ice Dams Lead To Mold
Ice dams occur due to many variables to include roof pitch, insulating properties and the amount of freezing and melting on the roof. The consequences of ice damming will last far beyond the winter season as moisture seeps into the attic sheathing and walls causing black mold.

“The Basement Smell”: Why Basement Air Is Unhealthy
Do you or know somebody who lives in a home with the noxious
“Basement Smell”? Based on thousands of
assessments we’ve conducted and the resulting tens of thousands of samples processed
as Indoor Air Quality Specialists, I can say with certainty that basement air is
the most compromised air in every house.
Even an apparently clean, finished basement often carries ten times the
pollution levels as upper floors and, because these pollutants are buoyant and
therefore rise, often spoil air in rooms above them. But, why does the air in
basements smell unhealthy enough that we’ve coined colloquial phrase after it?
Finished basements with carpeting and gypsum-based wallboard
may accentuate the “Basement Smell” and degrade the overall air quality because
carpeting absorbs moisture through the foundation in a process called capillary action; this capillary action
in turn creates excess humidity, putting more moisture into the air and wetting
the insulation. While carpeting manufacturers claim the carpeting is resistant
to mold, dusts, dirt and skin cells in the fibers are not. Combined with excess
moisture, conditions become ripe for smell molds like Penicllium and
Aspergillus. To even further complicate matters, standard gypsum wallboard is a
common source for the “Black Toxic Mold” such as Stachybotrys, Chaetomium, and
Ulocladium. Typically the insulation behind the wet wall will absorb the
moisture from exterior cement walls or a moisture intrusion source like a
sponge, making the backside—out-of-sight—moldy first. When you are able to see
patches of mold on the front of your wallboard, it is the tip of the ice berg.
As a note: even a one-time water damage incident can lead to Black Mold, which
can continue to grow and release pathogenic spores even after the wall has
dried. It may take months for this insulation to dry. Such environmental
circumstances lead to the foul odor we refer to as “The Basement Smell.”
Unfinished basements also create conditions optimal for mold
growth because they often contain more organic content (dust, dirt, debris),
encouraging fungal growth, than finished basements. Because basements are
typically designed with the limited cross flow ventilation, their lack of airflow,
combined the humidity from the capillary action described above, insight toxic
mold, bacteria and virus growth. It’s not just the toxic properties of these
pathogens that make for an unpleasant odor but the irritating and harmful microbial
volatile organic compounds (mVOCs) present.
So, when you say it “smells like a basement,” you’re really saying “these
mVOCs are out of control. I need fresh air!”
Stored utilities further degrade basement air quality by
spitting out ultrafine lung damaging debris referred to as particulate matter.
These particles ranging from 0.3-10.0 microns are so tiny you can’t see them,
but have the ability to infiltrate the lung tissue in your respiratory tract.
The smaller the particle, the more likely these toxins are to enter your blood
stream. Just because you have a door separating the finished to unfinished
section does not block these particles; you can fit hundreds of thousands of
these particles on a pinhead. At IndoorDoctor, we use digital meters to quantify
these particles so you can make informed decisions about how to properly service
and ventilate your basement.
Other environmental concerns contribute to an overall the unhealthy
basement environments that produce the “Basement Smell.” Some are listed below:
- Fiberglass: Often ignored, fiberglass insulation is another
pollutant that very common in basements; it can be found within walls, on
ceilings, stored in crawlspaces, and lining duct work. Unfortunately, despite
being a known carcinogen and terribly irritating to breathe, little effort
is made to reduce breathing in the tiny jagged glass particles. It is not uncommon to see exercise
equipment below or near exposed insulation even though the vibrations from
this equipment can jar thousands of lung-damaging glass particles into the
air.
- Crawlspaces: Crawlspaces are often so dank and
inaccessible that most homeowners don’t bother trying to make improvements
because redoing a foundation, tearing out walls, installing vapor barriers
becomes cost prohibitive. These crawlspaces , which are often nesting
areas for vermin, account for the majority of odors, With our advanced
equipment, IndoorDoctor can help you make sound practical decisions to
reduce the harmful toxins generated in crawlspaces.
- Radon: Radon is the 2nd leading cause of
lung cancer in the United States and New England is a hot spot for for the
gas due to the ledge and granite rock formations. Radon, which comes up
through the basement foundation, is colorless and odorless, making it
almost impossible to detect without the testing that the EPA suggests
every two years. Beware of uncapped
sump pits, too, which allow for greater passage of radon gas into your
airspace.
- Traditional Volatile Organic Compounds (VOCs): Traditional
Volatile Organic Compounds (VOCs), which are found in the paint cans and
fertilizer bags we tend to store in our basements because we cannot take
them to the dump, can also emit odors and have serious health effects.
So, what can you do about
the “Basement Smell” when you can’t get rid of your basement? The first step is
to get it tested. An Indoor Air Quality Specialist from IndoorDoctor can help
you quantify the molds, pathogens and other environmental factors that are
either emitting a foul odor or, sometimes even worse, are dormant below your
main living area. The information from these tests will help you develop a
cost-effective plan to reverse the conditions and improve your indoor air
quality. As I mentioned at the beginning of this article, basement environments
account for a large percentage of the Indoor Air Quality Assessments I conduct,
and I am confident that proper testing and follow-up will prevent you from
having to talk about your “Basement Smell.” Contact IndoorDoctor today to see how we can
make your home healthier.

Is Your Firewood Contaminated with Poison Ivy?
So you’ve just cut down some firewood from the back yard or gathering some sticks for the stove. Did you check to see if there were any harmful plants nearby like Poison Ivy? It’s not just touching the plant when cutting the wood that can cause you harm. Burning wood exposed to Poison ivy, poison oak, and poison sumac release an oil, urushiol, that when burned will release into the air. Because it's an oil, it sticks to just about everything it touches.
IndoorDoctor recommends that wood exposed to urushiol should not be burned. Even in winter you may contract poison ivy from touching wood you use to burn in the fireplace. The wood may be long dead but the urushiol remains active for up to several years. What's more, burning the wood may actually carry the allergen to your skin or you may even inhale it with the smoke and ash. It has been known to cause respiratory distress. If this happens, see a physician immediately. The smoke and gaseous by-products of burning urushiol may end up on your skin and in your lungs if you burn it in an inadequately ventilated stove or fireplace, resulting in severe medical distress. The oil from poison ivy is extremely stable and will stay potent - essentially forever. For example, you can get a rash from clothing or tools that have the oil from last summer, or even from many years back. Removal of the bark from the wood can help but that process has its own set of problems.

Visualize the Invisible Ultrafine Particulate Matter
Ultrafine particulates are lung damaging and enter the blood stream easier than larger particles. The IQair Purifier is one of the few purifiers out there that can filter these tiny particles.

5 Ways to Instantly Reduce Dangerous Indoor Airborne Particulate Matter
“Hear no evil, see no evil,” the saying goes, but your body
feels the damaging effects of tiny particles that penetrate deep into your
lungs. Ultrafine particulate matter are comprised
of tiny microscopic airborne particles containing biological and inorganic
matter such as pollen, dander, mold, and minerals. These particles are so
pervasive that they can enter] the blood stream and cause a wide variety of
illnesses. As a rule, If you can see the
dust particle in the air, there is a good chance your lungs can filter it. For
a point of reference the width of a human hair is about 100 microns; damaging
particles are significantly smaller: 5.0 and 10.0 . It is these invisible
particles that contribute to persistent coughing, watery eyes, and chronic
illness such as asthma. In order to prevent this, there are simple steps you
can take to reduce the amount of ultrafine particulate you breathe:
Step 1: Replace any
carpeting with hard wood floors. Your carpeting traps ultrafine
particulates. The same principle goes
for area rugs. Infants and toddlers are most prone to the ill effects of these
lung-damaging particles, as the crib or bed is often much lower to the floor.
The particulate levels at carpet level can be up to 100 times higher than at
regular breathing height. If you cannot afford to replace the carpeting, schedule
professional carpet cleaning using an experienced technician.
Step 2: Invest in a
quality vacuum. Most vacuums show a HEPA (High Efficiency Particulate Air) label and actually
perform as advertised on the box. The problem becomes when the HEPA filter
fails in a few months or year as it gets coated and clogged. The motor still
runs, forcing the ultrafine particulates through loose vacuum seals into the
air. Let’s put the “P” back into HEPA by maintaining your HEPA filter with
regular cleaning or replacing. Look for a true HEPA filter that passes higher
standards of emission certification.
Step 3: Encourage Air
Flow. How? Simple. Open the windows. If it’s cold or hot outside and you
are running a heating or cooling system, add a heat or energy recovery
ventilator system (HRV/ERV) to bring fresh conditioned, filtered air year round
into your home. It’s like leaving the windows open without the energy loss!
Instead of recirculating the same stale air you are now creating true air
exchanges into the home and reducing overall particulate levels.
Step 4: Run A Quality
Air Purifier. But which ones? There are hundreds of air purifiers out there that all
claim to do about the same thing. We started evaluating these various purifiers
during the course of our daily air quality assessments using a laser particle
scanner to measure the ultrafine particulate emission. Our studies found lower
particulate levels in the homes where people were regularly running an IQair (www.iqiar.com) and Austin Air (www.austinair.com) brand purifier.
Step 5: Maintain and
Clean Your Systems. Your furnace, air ducts, and even chimney can backfire
with exponential ultrafine particulates. Yearly attention to these critical
systems will ensure proper exhaust and filtration. We recommend hiring an
independent licensed technician who is experienced with your particular system.
Your technician should advise you without bias about whether a MERV 16 filter
is too much filtration and will cause your system to be clogged and should show
you why your furnace is not exhausting the harmful particles and fumes.

Why Your Front Loading Washing Machine Can Make You Sick from Toxic Mold
Instead of keeping you clean, many front-loading washing
machines can make you green with toxic mold and harmful bacteria’s. Water
accumulates behind the seals. You may not notice visual signs of mold but every
time you open and close the washer door you could be releasing tens of
thousands of toxic mold spores, usually of the Cladosporium type. In addition to inhaling this pathogenic spore
cloud you could exposure yourself to dermal issues by touching mold on the
surfaces of the door followed by ingesting the mold by not washing your
hands. Manufacturers of front loading
washing machines are snarled in Class Action Suits (see links below).
Surprisingly, the manufactures of such defective washing
machines continue to downplay the issue by contending mold formation and the
foul odor is a normal part of use. The
foul odor is actually a chemical release from biological growth known as a
microbial volatile organic compound (mVOC) which contain similar attributes to
traditional VOCs like paints, aerosols and petroleum based products. The ill effects from the mVOCs is
significantly worsened with the introduction of toxic spores. Some people may
not be affected by short term mold exposure, however, many people suffer
immediately from mold exposure and others from chronic exposure. To minimize
your mold risk when using a front loading washing machine we recommend:
1) Leaving
the door open after washing.
2) Sanitize
the door seals, gaskets and glass after laundering.
3) Dehumidify
or condition the laundry room if the relative humidity remains above 60%.
4) Run
a hot water wash with no clothes and use bleach or white vinegar instead of
detergent.
5) Remove
Clothes Promptly
6) Use
High-Efficiency Detergent
7) Add
a manufacturer recommended fan kit to your washing machine to accelerate the
drying process after use.
8) Run
the cleaning cycle at least as often as the manufacturer suggests
