Methods assess the presence of mold in an indoor environment
The choice of testing method depends on the specific goal
Air Samples
The most common method uses a "spore trap" and is called a "spore trap sample." Spore traps work by having a known volume of air pass impact a sticky surface as it passes through the spore trap sampling device. Most of the particles in the air also impact this sticky surface and consequently adhere to and are captured on this sticky surface. Mold spores comprise a subset of these 'particles in the air and are captured on the sticky medium inside the spore trap.
Surface Samples
Surface samples can be taken in a variety of ways. The three most common methods are:
Bulk samples
A piece of the sampled area is physically removed and sent to the mold testing laboratory.
Swab samples
Something akin to a cotton swab is rubbed across the area being sampled, often a measured area, and subsequently sent to the mold testing laboratory.
Tape samples
A piece of clear tape is pressed against and removed from the area being sampled, presumably picking up and removing part of any mold that was present on the surface, and then set to the mold testing laboratory for analysis.
ERMI Mold DNA Testing
ERMI testing uses DNA analysis to identify the mold species. The collected dust samples are analyzed using a technique called quantitative polymerase chain reaction (qPCR), which amplifies the DNA of mold spores present in the samples. This allows for the identification and quantification of specific mold species.
WHEN TO SAMPLE FOR MOLD
Here are some additional points about appropriate situations and goals for mold sampling:
- Baseline Sampling: Testing mold levels in a home when no known issues are present can provide a baseline for comparison to future tests if problems arise.
- Identify Moisture Sources: The location and severity of mold growth discovered during sampling can help pinpoint sources of excess moisture enabling the mold.
- Assess Remediation Scope: If considering professional remediation, test results determine how extensive the mold issue is, which guides the remediation plan.
- Evaluate Health Risks: Lab analysis of mold types and spore levels from sampling determine the potential severity of health impacts for occupants.
- Clearance Testing: This testing is done after remediation to verify the treatment was effective before occupants re-enter the home.
- Provide Peace of Mind: Even if no mold is visually evident, sampling can reassure occupants that mold is not present.

Ductwork provides an ideal environment for mold
Mold growth in HVAC ductwork is a common issue that arises when two key enabling factors are present - moisture and warm temperatures. Moisture accumulation happens when humidity levels inside the ducts are high, leading to condensation on interior duct surfaces, especially if there is temperature variability. Any water intrusion from leaks or external flooding can also introduce moisture. This moisture allows mold spores, naturally present in indoor air, to land on duct surfaces and propagate rapidly. Warm temperatures between 60-80°F, which are typical in ductwork, accelerate mold growth. The combination of moisture and warmth creates an ideal breeding ground for mold. Once established, mold colonies release more spores that spread through the home when the HVAC runs. This degrades indoor air quality and can cause health issues if occupants have allergies or asthma. In addition, mold buildup physically blocks airflow and reduces HVAC system efficiency. This results in higher energy bills and potential damage to HVAC components. Regular inspections, moisture control, and quick remediation are required to prevent extensive mold infestation within the ductwork.

ERMI TEST VS AIR QUALITY SAMPLING for Mold
MOLD Sampling For Mold Testing In south Florida
ERMI (Environmental Relative Moldiness Index) testing and air quality sampling are two different methods of testing for mold in a building.
ERMI testing involves collecting dust samples from a building and analyzing them for the presence of mold DNA. The results are used to calculate an ERMI score, which indicates the relative amount and types of mold species present in the building. ERMI testing is often used to provide a broad assessment of mold in a building and to identify potential health risks associated with mold exposure.
Air quality sampling, on the other hand, involves collecting air samples from a building and analyzing them for the presence of mold spores. The results provide information about the concentration and types of mold spores present in the air. Air quality sampling is often used to assess the current level of mold spores in a building and to determine if remediation efforts have been effective in reducing mold spore levels.
Both ERMI testing and air quality sampling can be useful in assessing mold problems in a building, but they have different strengths and limitations. ERMI testing provides a more comprehensive assessment of mold species present in a building, while air quality sampling provides information about the current level of mold spores in the air. Both methods can be useful in developing an effective remediation plan and monitoring the effectiveness of remediation efforts.
It's recommended to work with a qualified mold inspector or remediation professional to determine the most appropriate testing method for a specific building and to interpret the results accurately.
