Provide Peace of Mind to Occupants with an IndoorAir Quality Assessment & Certification

Survey

Information is gathered about your space to uncover latent and apparent risk factors that can identify where a more in-depth focus is needed to help tailor corrective actions

Mold, Moisture & Humidity

Robust testing and analysis can identify the root cause of moisture and mold to ensure proper remediation and resolution

TVOCS, CO, NO2, Ozone

Cleaning chemicals, building materials, and combustion appliances create unhealthy IAQ. This has a variety of adverse outcomes from impaired cognitive function to headaches and irritation

Particulate Matter

PM 2.5 are microscopic particles (virus, bacteria, dust). Elevated levels can indicate an unhealthy building which needs filtration improvements or revised cleaning products

Ventilation (CO2)

Improper air exchange results in increased viral load (if lacking) and high operating costs (if excessive). We help buildings determine their air changes per hour (ACH) by conducting ventilation studies

Scorecard & Testing Plaque

Our scorecard/report provides a corrective action roadmap for how to prioritize indoor environmental quality investments. The plaque demonstrates your commitment to improving conditions
