This consumer test kit is an effective way to screen your home or workplace for the presence of mold, both allergenic and toxic in nature from strategic surface sampling points by utilizing a revolutionary sample collection device called the Bio-Scan400. Everything we breathe will eventually fall to a surface. Some particulates (particles) are relatively heavy in nature, and will settle on various surfaces quicker than others. For example, the air you’re breathing today may not be the same as what you were breathing last month, last week, or even a few days ago. Therefore the Bio-Scan400 is a very effective tool in providing accurate, detailed analysis of the air we breathe and the pollutants that may be present.
