Indoor Air Quality Testing Services

At We Know Mold, we take mold detection seriously—because what you can’t see can still affect your health. Our Indoor Air Quality (IAQ) testing process uses Air-O-Cell sampling to accurately detect and quantify airborne mold spores in your home or business.

Whether you suspect hidden mold, need clearance after remediation, or want peace of mind before buying or selling a property, our certified inspectors are here to help.

Air-O-Cells are industry-standard sampling cassettes designed to capture airborne particles—including mold spores, pollen, and other bioaerosols—for laboratory analysis. They’re highly effective for identifying:

• Hidden mold sources
   
• Elevated mold levels
   
• Cross-contamination from affected to unaffected areas
   
• Indoor vs. outdoor air quality comparisons
   

These samples are non-destructive, quick to collect, and provide valuable data to guide remediation or confirm a clean environment.

1. Visual Inspection & Moisture Mapping
   We begin with a thorough visual assessment and moisture detection using thermal cameras and moisture meters to identify suspect areas.
    
2. Strategic Air Sample Placement
   Our certified mold inspector places Air-O-Cell cassettes in:
    
   • Affected indoor areas (e.g., near visible mold or musty smells)
      
   • Unaffected “control” areas
      
   • Outdoor reference location (for baseline comparison)
      

1. Air Sampling Procedure
   Each Air-O-Cell is attached to a calibrated air sampling pump that draws a controlled volume of air (typically 15–20 liters per minute for 5 minutes). This pulls airborne particles onto a sticky glass slide inside the cassette.
    
2. Lab Analysis by Accredited Laboratory
   The samples are sealed, labeled, and shipped to an AIHA-accredited laboratory, where a microbiologist analyzes the spore types, quantities, and concentrations under a microscope.
    
3. Detailed Report & Interpretation
   You’ll receive a full lab report within 2–3 business days, along with our expert interpretation, which includes:
    
   • Spore types and concentrations
      
   • Comparison to outdoor levels
      
   • Risk assessment
      
   • Recommendations for remediation, if needed
      

• Certified Mold Inspectors with IICRC and Lead Renovator credentials
   
• Accurate, unbiased testing with third-party lab analysis
   
• Over 17 years of mold assessment and remediation experience
   
• Clear explanations—no scare tactics, just science
   

Breathe easier with answers. Whether you're concerned about mold or need post-remediation clearance, We Know Mold delivers reliable air quality testing you can trust.
