As it is has been established with research and studies that mold spores causes a wide range of health hazard of varying degrees of seriousness, it has become clear that a systematic way of controlling its growth and totally eliminating it if possible is needed. To be successful in controlling mold spores, the conditions that favor its growth and proliferation should be considered. Once understood, these factors can be used in formulating strategies that will be effective in its control, if not at all its total elimination.
Molds have the capacity to grow everywhere so long as moisture is present. Since its spores are present in the air and dust, it can be found everywhere, whether outside or inside. Indoor mold growth are caused by several factors, the most prominent of which is related to water and moisture. Maintenance problems such as leaky roof, plumbing problems, and incomplete drying of flooring materials; all of these are contributing factors towards indoor mold growth. Apart from these factors, common building materials such as plywood, drywall, furring strips, carpet, and carpet padding serve as food for molds. These materials, when combined with the presence of humidity, catalyze mold growth. Mold growth itself will not appear to be suddenly obvious, but will wait for the proper timing when enough moisture is available.
There are many factors that can cause moisture build up indoors. Apart from the maintenance problems as discussed above, insufficient ventilation can contribute to moisture build up, so it is very important that air conditioning systems should be working properly. Usually, mold colonies will grow fastest where ventilation is poorest. Homes that are too air-tight will tend to experience mold problems during the warmer months. This is because humidity is normally at high levels during these months, causing moisture to be trapped inside. Drafty homes, on the other hand, usually have problems regarding mold growth during the colder months, due to the warm air escaping from the house’ living area towards unconditioned spaces, where it undergoes the process of condensation.
As can be seen from the discussions above, it is clear that molds need the following materials to grow: moisture, food (some building and/or construction materials, dust, dander, etc), and warmth. Unfortunately, HVAC (air-conditioning) systems can create exactly these factors for mold growth. This is because it causes condensation, circulation of dusty air, and regular warm conditions to occur all in a cycle. However, the use of proper filtration material should help to resolve the problem of dusty air circulation, while insulating the supply air ducts will help to eliminate the condensation which creates moisture conducive for mold growth.
