Indoor Air Quality

Indoor Air Quality & Respiratory Health -  Peace of mind. Guaranteed.

Handheld detection of gases and particulates inside buildings for a safer breathing environment.

Occupants who work indoors spend on average 8 hours a day breathing the air inside the building. Poor indoor air quality not only reduces productivity and feelings of wellbeing but can leave occupants vulnerable to developing severe, or exacerbating existing, respiratory health issues.

The air quality inside buildings is affected by:

  • Dust
  • Spores
  • Smoke
  • Organic compounds
  • Build-up of gas and/or gas emissions
  • Humidity levels
  • Inadequate ventilation

With the YESAIR Indoor Air Quality Monitor you have the power in your hands to know the level of air quality and respond accordingly.


Monitoring the indoor air can:

  • Identify the levels of indoor air contaminants
  • Determine if fresh air intake to re-circulated air ratio is adequate
  • Improve processes required to guarantee healthier indoor air 
  • Provide a log of readings for constant analysis so modifications can be made appropriately
  • Increase comfort and productivity
  • Prevent and reduce sickness

  • Ozone (O3)
  • Formaldehyde (CH2O)
  • Particulates (PM2.5)
  • Volatile Organic Compounds (VOCs)
  • Temperature
  • Relative Humidity
  • Carbon Dioxide (CO2)
  • Carbon Monoxide (CO)

If record keeping is required, an optional high capacity data logging package with a 2GB SD memory card and software for collecting, analyzing and graphing data is available.
