Mycometer air Fungi
Examples of interpretation
Mycometer air Fungi or MAF is a method based on activated air sampling according to the “Mycometer Protocol for Activated air Sampling” (Mycometer©).
Results are divided into5 interpretation categories: A+, A, B, C and D, derived from the investigation and comparison of samples from of non-problem buildings and well as buildings with mold problem. (se table with interpretation below).
The MAF value is an indicator of potential mold exposure level.
Examples
Case 1 Shows results from an investigation of a bedroom and a living room.
The value of 117 in the bedroom is a category A value indicating the typically level found in rooms in non-problem buildings. The mold level was 1211 in the living room which is a category C result. This can indicate a mold source or an inadequate cleaning standard.
If looking for a mold source, a FAI sample is a better tool.
Case 2 Shows results from after a mold remediation where a successful post remediation verification cleaning (PRV) has been performed. Three samples in category A+.
The Value levels of A+ and A indicates that the levels of mold in the bedrooms after cleaning are low and corresponds to the level found in buildings without mold problems and with normal cleaning standards
Interpretation criteria
Mycometer air Fungi measures the level of fungal particles such as fungal spores, micro-, and hyphal fragments. The method is quantitative and shows the level of fungi present and thereby the potential exposure in the given room.
Activated air sampling means that a standard protocol defined by Mycometer A/S has been used, where settled dust particles are resuspended in the air. Activated sampling has been shown to give representative and reproducible sample results.
Hidden fungal growth e.g., within wall cavities or below the floor cannot always be revealed using air samples or dust samples independent of what method is being used. If fungal growth is effectively encapsulated so that no fungal particles can escape or have no contaminant pathway into the space, the hidden fungal growth cannot be revealed.
Non-problem buildings are defined here as buildings which after inspection show no visual signs of mold growth or visual moisture damage, no musty smell, or other indications of a mold problem.
