Mosynex equips you with professional-grade tools to detect hidden moldno lab background required. Your Mosynex mold testing kit includes pre-poured agar test plates, sterile cotton swabs, disposable gloves, a labeling marker, a step-by-step User Manual, a quick-scan Mold Identification Guide, a downloadable HD poster, and a free lab-analysis voucher, providing everything needed for simple testing. Three simple testing modes are available: for air sampling, close windows for 6 hours before exposing an open plate on a table for 1 hour and then sealing it; for HVAC samples, tape an open plate to a supply vent, run the fan on HIGH for 10 minutes, and seal the plate; for surface testing, swab any suspect spot and lightly streak the swab over the agar before sealing the plate. Always incubate sealed plates upside-down, checking for growth after 48 hours and then daily up to 7 days; when finished, discard the sealed plates inside a zip bag. Founded by environmental scientists, Mosynex develops easy and reliable testing kits for home mold.
