Indoor air quality — measured, interpreted, actionable.
Bad air shows up as symptoms long before anyone agrees on a cause. Envirex measures the actual contaminants — at the right levels, with the right interpretation — and tells you what's driving them.
What's in scope.
Below is the standard scope for an Envirex indoor air quality testing engagement. We size the project to the building — line-item, fixed-fee — and write the quote against this catalog.
Volatile Organic Compounds (VOCs).Active or passive sampling for the EPA TO-15 panel — solvents, plasticizers, off-gassing from new finishes, fuel-derived vapors.
Formaldehyde & aldehydes.Targeted sampling on engineered wood, cabinetry, post-renovation interiors and complaint investigations.
Mold spores.Indoor and outdoor (baseline) bioaerosol cassettes analyzed at an AIHA-LAP lab for spore-type ratios.
Particulates (PM2.5 / PM10).Real-time and integrated measurements for ventilation diagnostics and tenant complaints.
CO₂ & ventilation diagnostics.Carbon dioxide and temperature/RH profiling to evaluate ventilation rates against ASHRAE 62.1 guidelines.
Allergens & specialty panels.Dust mite, cockroach, pet allergen, lead-in-dust, asbestos awareness — to scope.
Regulatory framework.
Every Envirex engagement is run against the regulator who will ultimately read the report. Here are the rules that shape indoor air quality testing work in New York.
EPA TO-15 / TO-17.Reference methods for indoor VOC measurement.
ASHRAE Standard 62.1.Ventilation for Acceptable Indoor Air Quality.
WELL / RESET / LEED IAQ.Where the engagement supports a building rating, sampling is performed to the rating's protocol.
OSHA / NIOSH.Occupational exposure thresholds applied to workplace investigations.
Best suited for.
Occupant-health complaints, post-renovation commissioning, schools and daycare, expert witness work, building-rating documentation.
What you receive.
Lab-backed report with measured values, contextual benchmarks (ASHRAE, EPA, WELL where applicable), and a recommended action plan.
