Air Quality Monitoring
The air you breathe indoors can be more polluted than the air outside, and poor air quality can affect your health without you ever realizing the cause. STOS Environmental LLC provides professional air quality monitoring across Phoenix and all of Arizona, assessing and monitoring indoor air to ensure safe, breathable environments.
Our team uses professional-grade monitoring equipment to detect mold spores, asbestos fibers, volatile organic compounds, particulate matter, and other airborne hazards. We help you understand your indoor air quality and take action when problems are found.

Indoor air quality monitoring is the measurement and analysis of the air inside homes, offices, and other buildings to identify contaminants that could affect health and comfort. Common indoor air hazards include mold spores, asbestos fibers, lead dust, volatile organic compounds (VOCs), carbon monoxide, and particulate matter. Many of these are invisible and odorless, yet they can cause headaches, allergies, respiratory problems, and more serious illness.
Our monitoring services begin with an assessment of your property and any concerns or symptoms you're experiencing. We then deploy professional-grade air monitoring equipment to sample the air and measure contaminant levels. This includes air pumps and cassettes for asbestos and mold, real-time particulate monitors, gas detectors for carbon monoxide and VOCs, and humidity measurement to assess mold risk.
Air quality monitoring is particularly important in several situations. If you've recently experienced water damage or a fire, airborne contaminants may be elevated. If your home or building contains older materials that may include asbestos or lead, monitoring can detect hazardous fibers or dust. If you or your family are experiencing unexplained health symptoms, air quality testing can help identify the cause. And after remediation work, monitoring verifies that the air is clean and safe to breathe.
In Arizona, monsoon season and the associated moisture can contribute to indoor air quality problems, including elevated mold spore counts. Poor ventilation in tightly sealed modern buildings can also trap pollutants indoors. Our monitoring services help you identify these issues and develop a plan to address them.
Why choose professional air quality monitoring over a DIY approach? Professional equipment and methodology produce accurate, reliable results that DIY kits can't match. We use the right sampling methods for the specific contaminants we're testing for, and we provide a clear, comprehensive report of our findings. When issues are identified, STOS can perform the necessary remediation — from mold remediation and asbestos abatement to water damage restoration.
