This kit comes with 4 micro5s (3 INDOOR SAMPLES + EXTERIOR REFERENCE) MUST RETURN AIR PUMP WITH SAMPLES Concerned about potentially toxic mold spores in your air? The DIY Mold Air Test Kit gives you everything you need to test for hidden mold problems in your home, office, or rental property—without the high cost of professional service. This complete kit includes a rental air pump, your selected number of spore canisters (2–15), lab analysis, expert consultation, and prepaid return shipping. Unlike many store-bought kits, this professional-grade solution captures mold spore concentrations in spores per cubic meter—the most accurate way to assess true indoor air quality. Using Micro5 spore trap canisters, the same tools trusted by IAQ professionals, you'll collect up to 20 air samples. Samples are then analyzed by an aerobiologist at a lab to identify mold types, levels, and potential toxicity—including spores that traditional petri dishes often miss. ✔ MUST RETURN THE PUMP & SPORE CANISTERS TO THE LAB using the included prepaid shipping label. ✔ An outdoor reference sample is required with all orders—for example, if you order 3 samples, use 2 indoors and 1 outdoors. You'll also receive a detailed lab report and a consultation with a mold expert to explain what your results mean and what steps to take next. Ideal for homeowners, renters, real estate transactions, landlords, and IAQ professionals, this kit is a fast, accurate, and flexible solution for identifying airborne mold—especially after water damage or if you're experiencing unexplained allergies, respiratory issues, or musty odors.
