Ensure Compliance with International Air Quality Standards

The AI-IAQ6-PH contributes to compliance with international air quality and green building standards, including: 

  1. Leadership in Energy and Efficient Design (LEED): LEED certification is one of the most widely recognized green building rating systems worldwide. LEED emphasizes sustainable building practices and includes requirements related to indoor air quality. Monitoring the specified parameters can contribute to meeting LEED certification requirements for indoor environmental quality.

  2. WELL Standard: Introduced by the International WELL Building Institute (IWBI), the WELL building standard requires the measurement of at least 3 parameters to meet indoor air quality monitoring criteria.
    PM2.5 or PM10
  • Carbon dioxide
  • Carbon monoxide
  • Ozone
  • Nitrogen dioxide
  • Total VOCs
  • Formaldehyde

    The AI-IAQ6-PH enables monitoring of CO2, TVOC, and Particulate Matter (PM2.5, PM10) contributing  positively to WELL building requirements.
