Recommended Next Steps
Keep your current filter schedule
Your filter is doing its job. Replace every 60–90 days to maintain these results.
Watch airborne particle levels
PM2.5 and dust are slightly elevated. Consider a MERV 11 or higher filter on your next replacement.
Allergy-friendly practices during high pollen season
Keep windows closed on high pollen days. Run HVAC fan continuously during peak season.
Retest in 6 months
Monitor seasonal changes with a follow-up test in late fall or early winter.
Understanding Your Results — QFF Methodology
Test Your World uses Quantitative Filter Forensics (QFF) — a method that analyzes HVAC filters that have been collecting particles for 30–90+ days. Unlike traditional air sampling, we do not take an outdoor control sample. Any filter in use will capture some outdoor spores that infiltrated the building.
Background thresholds applied: Low counts of even “dangerous” molds like Stachybotrys (≤10), Chaetomium (≤15), and Fusarium (≤20) are expected and do NOT indicate an indoor mold problem. Common outdoor molds like Cladosporium (≤500) and Basidiospores (≤1,000) at these levels confirm normal ventilation is working.
Vertical bars in the species breakdown show each organism's count against the 500-count analysis scale. The thin vertical line marks the threshold for that species.
Disclaimer: This is a screening tool for informational purposes only and is not a medical test. Results are based on debris found in your filter sample and are not a substitute for professional advice. Spore calculations are estimates based on registration data. Always consult a certified mold professional for concerns about mold in your home.
