Mold and Mildew

Mold and mildew growth occurs in stages that are based on moisture availability. In the final vigorous stage, the fungus is able to generate and maintain enough moisture through its natural metabolism to maintain growth such that moisture from the air is no longer required.

The primary method of controlling mold and mildew is to provide a dry environment. Preventing actual condensation controls the growth of most hazardous molds, but it’s the relative water content of the food source (called the “water activity”) that inhibits mold growth. As a result, cold surfaces combined with high dew points create more frequent and serious mold growth than simple high relative humidity, hence it is the combination of dry, cool, and clean air and not dry air alone, that combats mold and mildew most effectively.

A secondary method of controlling mold and mildew is to provide a clean air environment through the process of filtering. Filtering of particles larger than 1.0 micron (0.001mm) significantly reduces the number of fungi spores introduced to the environment and thereby limits their detrimental – and potentially dangerous – effects.
