Mold & Indoor Air Quality (IAQ) Testing: A Step-by-Step Field Guide

Written by SpecuLink Technical Research Team

The Growing Demand for Indoor Air Quality Testing

With increased awareness surrounding mold-related health concerns, home buyers frequently request Indoor Air Quality (IAQ) testing. Offering spore trap air sampling allows home inspectors to provide scientific lab-backed answers while boosting average revenue per inspection by $250 to $400.


1. Spore Trap Air Sampling Calibration & Protocol

Air sampling utilizes a calibrated electric air pump set to a flow rate of 15 Liters Per Minute (LPM) with impactor cassettes (e.g. Air-O-Cell or MoldSnap). Running the pump for 5 minutes draws a 75-liter air sample across a sticky glass slide inside the cassette.


2. The Mandatory Outdoor Baseline Control Sample

Air quality results are meaningless without an outdoor baseline control sample. Ambient outdoor air contains natural background mold spores (such as Cladosporium or Alternaria). Taking an outdoor control sample on the same day establishes normal baseline spore counts for comparison against indoor room samples.

If indoor air samples reveal high concentrations of indicator molds like Stachybotrys chartarum or Aspergillus/Penicillium that are absent outdoors, an active indoor moisture problem and mold reservoir is confirmed.


3. Automated IAQ Lab Data Uploads in SpecuLink

SpecuLink streamlines environmental lab reporting. When your lab returns spore count PDF results, SpecuLink automatically parses lab data tables, generates visual spore count comparison charts, and embeds professional remediation disclaimers into your report deliverable.
