Many of our competitors have introduced unproven and untested products and procedures that lack credible scientific evaluation. Inadequate testing of products and procedures and unsubstantiated technology are abundant among the vast majority of companies that attempt to provide viable solutions to mold, mildew and problems associated with poor indoor air quality.
Mold Sentry has gone to great lengths (and will continue) to substantiate and document the effectiveness of our system. We’ve performed numerous performance, safety, quantitative and qualitative tests.
Independent tests have convincingly concluded that the Mold Sentry system is very effective at substantially reducing indoor air contaminant levels. Additionally, the negative affects associated with moisture and mold, as they relate to health problems and structural property damage, have been greatly reduced. Documented results of multiple tests have proven that the Mold Sentry system provides a permanent solution to problems associated with mold, moisture and poor indoor air quality.
Our system has been tested and proven so that you can breathe easier.
Our System has been independently tested by EMSL and The University of Toledo.

Conclusions:
- Data obtained during testing of the air handling system produced by Mold Sentry demonstrates that the unit reduces the number of viable and non-viable mold spores in the air and on surfaces.
- The air handling system has been found to reduce the humidity, a primary influence on the growth of fungi, within a building.
Prior to testing, the circulating fans in room C were turned off in order to simulate a space with poor air circulation. Sampling of the containment area was performed prior to activating the air handling system in order to establish the baseline for the experiment. The unit was activated for a total of three hours, during which airborne spore sampling, temperature and humidity were recorded. At the end of three hours the unit was deactivated and full sampling of the containment commenced.
Analysis and Discussion:
Airborne total spore counts were performed with Air-O-Cell cassettes using a sample volume of fifteen liters per cassette. Viable spore count sampling was performed with the Anderson Impactor using a sample volume of thirty-two liters per sample with incubation. Agar plates for sampling the concentration of viable spores that settled on the floor was performed by incubation. Adhesive lifts were used to sample the spores settled on the floor by direct contact.
Analysis was performed by direct microscopy for the total airborne mold and the adhesive lift samples to determine the total spore concentrations. Incubation with colony counting was performed on the viable airborne and settled mold spores in order to determine the Colony Forming Units (CFU).
The data obtained from the analysis of the total airborne mold testing by Air-O-Cell cassette revealed an average drop in spore concentrations of eleven percent (11%) after a three hour time period (Table D). Examination of the airborne viable mold analysis by Anderson Impactor revealed a forty-six percent (46%) reduction after a three hour time period (Table C). Analysis of adhesive lifts from four locations, two in the large room and one per small room, did not reveal any significant evidence of surface mold accumulation during the experiment. While some settling may occur, the variation between pre- and post- unit activation is unlikely to account for the decrease in airborne spore concentrations.
Analysis of the settled spore concentrations by adhesive lifts resulted in an average spore concentration near one hundred fifteen (115) structures per square inch. The average concentration of viable spores was calculated to be near fifty-three (53) structures per square inch, which is a fifty-four percent (54%) reduction in total to living fungal spores (Table A).
Analysis of the viable mold spore concentrations with respect to proximity to the UV light sources used by the air handling system revealed a distinct correlation between the distance from the light and the amount of living fungi. The average CFU per square inch at a distance of seven feet is near seventy (70). The number drops to near seventeen (17) CFU at a distance of four feet. The data shows that the UV light source produces a seventy-five percent (75%) reduction in viable spores between a direct linear distance of seven feet to four feet from the light source (Table B), which consistent with the relative intensity of the radiation at these distances.
Monitoring of the containment area for temperature and humidity during the three hour run time revealed an increase in the temperature and a decrease in the relative humidity. While the temperature increased by nearly two degrees centigrade (3.8°F), the relative humidity dropped by nearly twenty-seven percent (27%). Due to the sealed nature of the containment area it is likely that the relative humidity will experience a greater decrease in a normal building, which would have the benefits of additional airflow, including outside air. Any variation in temperature due to specific building characteristics cannot be speculated upon at this point.
The data obtained during this experiment suggests that the air handling system manufactured by Mold Sentry is effective in reducing the amount of viable mold spores in a building crawlspace. In addition, the total mold spore population is reduced. The data supports the conclusion that surface mold growth is inhibited by the presence of the UV lighting associated with the unit. The reduction in relative humidity produced by the air handling system also reduces the potential for further mold growth.
