We use Air-O-Cell cassette sampling, which is the standard method in the indoor air quality industry. A calibrated pump pulls a known volume of your indoor air across a sticky collection slide, catching mold spores, fragments, and other particles. We sample the rooms where you actually spend time (bedrooms, living areas, wherever symptoms are worst) and one outdoor control sample so the lab has a baseline for your area. Everything goes to an independent certified lab, where a technician looks at each slide under a microscope, identifies the spores by genus, and counts them room by room. You get the full report within a few business days. This isn’t a handheld meter flashing a number at you. You get real numbers you can take to your doctor, your insurance company, or use to make a decision about your house.
