How Is A Water Mold Able To Reproduce
Water molds Water molds are heterotrophs and resemble fungi. They can exist as unicellular organism or as fine filaments. They are parasites and free. Water fungi can reproduce sexually by fertilization and asexually by spores. They absorb food from the environment or invade and feed on other organisms.
How To Fix Humidity Problems In The Home
A home that has high relative humidity problems indicates there is a problems with the HVAC system, ventilation or poor living habits such as running the air conditioning with the windows open. A licensed HVAC contractor or engineer may need to be contacted.
But that sounds expensive, right?
Well another option is:
Get an external dehumidifier. This is especially good if you are just having a humidity problem in one section of the home.
External dehumidifiers can work great and don’t necessarily need to be ran 24 hours a day. You can run it for a few hours in a room while you are somewhere else in the home and it can make a big difference.
The downside about external dehumidifiers is they need to be emptied because they fill up with water pretty easily.
To prevent humidity problems that can lead to condensation, you should also make sure the air conditioning is set to the “Auto” position and not “On”. You will really start to see mold growing on your clothes if you do this.

Facts About Mold And Indoor Air Quality
As previously mentioned, mold is more than just a pricey cleanup issue. Its a health hazard! Consider these facts about how mold affects indoor air quality and can impact the health of the people who breathe the contaminated air:
- According to a recent consumer survey, 76% of people who lived in a home with a wet basement feared that they and their families were being harmed by mold. Of that group, 30% said they or someone in their household experienced symptoms of poor air quality associated with mold. These symptoms include coughing, headaches, loss of energy and general fatigue, skin issues, shortness of breath, and watery eyes.
- According to the American Lung Association, there are likely thousands of different types of airborne germs, including viruses, fungi, and bacteria. When these germs are combined with mold spores, they can cause a number of respiratory illnesses. These can be as mild as a common cold or as severe as pneumonia and other respiratory infections.
- Airborne mold spores can exacerbate allergies, asthma and other respiratory diseases. In fact, its not uncommon for allergy-sufferers to experience full blown allergy attacks when exposed to even trace amounts of mold spores. Over time, these attacks can significantly deteriorate and weaken the lungs.
Poor Reason For Testing #2 To Identify What Type Of Mold Is Present
Some testing can be used to identify a portion of the live mold in a sample by growing it in the lab. This gives only a partial description of the total amount of molds, because those not present at the sampled time and location or those that didnt grow in the sample are not seen by the analysis. Most importantly, nonliving molds will not be identifiable, but they can still contribute significantly to health complaints.
From a practical, health-protective perspective, knowing the types of molds is usually not very important because any indoor mold growth represents a problem. The problem should be corrected regardless of the types of molds that can be identified.

There are a good number of EMSL labs throughout the US, so dependant on your location, you can actually get results in 24-hours if you really need them. That is quicker than any other test kit on this list.
The kits themselves are very easy to set-up and they will grow spores within a few hours once placed correctly. They aren’t as good for HVAC testing as our top choice, but handle all other rooms with ease. Overall, highly recommended if you need to know exactly what mold you’re dealing with.
How To Choose The Best Mold Test Kit
There are a few key things to consider when selecting a mold test kit. These include the types of supplies that are included and the customer support that’s available. Here are the main factors to think about to make sure you choose the best mold test kit for your situation.
Test supplies
It is important to find a mold test kit that includes all of the equipment necessary to collect complete samples. If a test kit can collect surface samples but does not include swabs or adhesive strips, youll have to look elsewhere to buy these items at an added cost. Usually, you can determine the types of tests the kit can perform by looking at the included supplies.
Help and support
Reputable mold test companies include their telephone numbers and email addresses on their websites. In addition to contact information, you might want to select a company that has strong support options, including FAQs and video tutorials. Aside from our top two products, the Pro-Lab Mold Test Kit and the Home Mold Laboratory Viable Mold Test Kit, you can find full customer support with Healthful Home’s 5-Minute Mold Test and the Mold Check Whole House Mold Test.
It also is handy if either the kit itself or the website offers a guidebook to tell you how to test for mold and identify what you find.

High Risk Of False Negative Results In Mold Tests
Mold spore counts are questionable in the first place, given the high variability that we discuss in this article.
But “low” or “negative” mold spore counts, especially if not accompanied by a thorough visual inspection and collection of the building’s leak history and occupant complaint history, are particularly suspect.
Individual samples of particles in air show tremendous variation from minute to minute, making “ok” airborne mold spore test results a thing to view with skepticism.
Examples of factors which can cause an exponential difference in particle levels in indoor residential air over short time intervals include: mechanical disturbance , operation of hot air heating system or central air conditioning system, operation of other building fans, particularly ceiling fans and vacuum cleaners, turning lights on and off, and opening or closing windows and doors.
In situations of particular risk, additional or periodic testing should be considered. Below we list these sources of mold test variation and give photos and mold test examples for specific variation sources.
Our experience is that the variation in the level of small indoor airborne particles is so significant that any indoor airborne particle count is likely to be an inaccurate guess at the actual occupant exposure level where indoor problematic molds are present. T
At AIRBORNE PARTICLE COUNT VARIATION CAUSES we list the chief sources in the short term variation in the level of airborne particle levels.
How To Identify Mold In Walls
Identifying surface mold leads to the identification of mold inside walls. If there is a considerable amount of mold on your walls, then it may be time to look inside.
A significant amount of surface mold is a symptom of a thoroughly contaminated interior. Also, if your home has recently been flooded or water-damaged, then mold may have grown beyond the surface.
Lastly, if you smell a musty and pungent scent on your walls but cannot see any surface mold, then its likely to be an interior mold.

What Is Black Mold
When people say black mold, they refer to Stachybotrys, a greenish-black mold that grows on damp material with a high cellulose content. In our homes, that includes wood, fiber or gypsum board, paper, fabric, or green insulation. Just because mold is black doesnt mean its the dreaded Stachybotrys though, which by the way also manifests itself in blue and grey. But because Stachybotrys can off-gas dangerous mycotoxins, its the mold variety most feared.

Reply: Summary of common reasons for mold growth on drywall
A competent onsite inspection by an expert usually finds additional clues that help accurately diagnose a problem. That said, here are some things to consider:
Possible reasons for indoor mold growth ?
In all cases of indoor mold growth the mold needs food , oxygen, and water some molds thrive on light, some are tolerant or intolerant of UV, and other factors.
Moisture, water, leaks, condensationa are key determinants in indoor mold growth
Of all of these, water is the key necessary ingredient which we can track and which is inviolate that is, no water, no moisture = no problem mold growth.
I have no context for the photos, no age, no building history, occupancy, use, or other key information that an onsite inspection would disclose.
But I note that your middle photo looks as if it is a ceiling and because there is a vent therein I suspect this may be over a bathroom Common moisture sources for such an area might include
- leaks into the ceiling above
- high indoor moisture from in-building sources such as a steamy shower or clothes dryer
- leaks from the ducting for the ceiling fan

What Causes High Humidity In The Home
Think back to that locker room smell again
What happens in that locker room besides horseplay by kids?
Showering, or so we can only hope!
Well hot showers can create high relative humidity within bathrooms. If the bathroom isn’t ventilated properly this can create a dew point.
Bathrooms can be a prime source of high humidity, but most bathrooms are built to withstand it.
One of the main causes of high humidity is an air conditioning unit that is not properly functioning. If your air conditioning is not dehumidifying properly it could also be a sign that is it undersized or oversized.

How Are Air Test For Mold Conducted
Non-viable air samples are usually collected using a slit-impaction sampling device which employs a calibrated air pump to collect a measured volume of air in the environment being studied. Particles in the sampled volume of air are collected as they impact on to specially prepared microscope slides or inside of patented cassettes placed in the collection device’s air path.
The collection device may be any of several air sampling machines , or it may be a calibrated air pump, or a vacuum pump used with an Air-O-Cell cassette. Multiple period time-lapse sampling is available to diagnose difficult situations but is not normally employed.
In special cases, we may use a separate pump and cassette system to sample surfaces and wall or ceiling cavities, although in general building cavity vacuum samples made through small openings have time and again proven grossly inaccurate.
