The QWIK PRODUCTS QT4200 is a mold test kit designed for HVAC technicians, indoor air quality professionals, and service contractors who need to collect and document mold samples in the field. The kit uses adhesive sample tape to lift surface and duct samples without specialized equipment. Collected samples are submitted postage-paid to Mainstream Lab, where certified analysts produce a customized written lab report. This workflow allows technicians to provide clients with documented, professional-grade mold identification results rather than visual-only assessments.
The QT4200 is suited for residential and light commercial HVAC service calls where mold growth is suspected in ductwork, air handlers, coil housings, or on accessible surfaces. It is a practical addition to maintenance, inspection, and remediation verification workflows. Indoor air quality consultants and general HVAC service technicians are the primary installers and users of this kit.
Designed for general mold sampling on HVAC surfaces, ductwork, and building materials in residential and light commercial applications.
Mold sampling is typically performed by licensed HVAC technicians or certified indoor air quality professionals. Before collecting samples inside air handlers or duct systems, power down the HVAC unit at the disconnect or breaker to prevent accidental fan activation during sampling. Follow the collection instructions included with the kit precisely to avoid sample contamination. Handle all sample materials with gloves and avoid touching the adhesive tape surface prior to collection.
