If your home has odors, it may not be because of mold. Poor ventilation could be the cause of your odors.
ASHRE recommends that the air inside your home be 'exchanged' between 18 and 48 times per day. As construction practices create more energy efficient homes, natural ventilation decreases dramatically. The higher energy efficient homes of today, are less likely to breathe to conserve energy and are tightly sealed. If odors, off gasses, Volatile Organic Compounds (VOC's), are not removed from the home, then this will dramatically negatively impact your indoor air quality. The World Health Organization estimates that 30% of all new or newly remodeled structures may be linked to sick building syndrome as a direct result of lack of ventilation.
