3. The cumulative total of various volatile organic compounds (TVOC) is shown on line (4). This
measurement corresponds to the total detected values of multiple pollutants.
Volatile organic compounds, including benzene, are pollutants derived from hydrocarbons, solvents,
exhaust fumes, etc.

RECOMMENDATIONS
Green
0–0.600 mg/m³
Good
Continue airing the room regularly to renew the
air.
Yellow
0.601–1.000 mg/m³
Modest
Air the room; leave the room for now.
Limit heating during winter.
Red
1.001–5.0 mg/m³
Bad
(danger)
Air the room and leave it.
Install a permanent ventilation system.
Identify and reduce all sources of possible
pollution (furniture, ceiling, floor and wall
coverings, home improvement work, painting,
etc.).
The values detected by the tester at a given moment can often be higher than the exposure threshold.
That’s why each threshold is coupled to a specific exposure time. If the measured values regularly
exceed these limits, a professional diagnosis is advisable to identify the source of the pollutants.
The AQI (Air Quality Index) uses coloured bands for easy interpretation of the air quality:
Green: 0-75 The air quality is good (Good)
Yellow: 76-150 The air quality is tolerable (Slight)
Red: 151-300 The air quality is poor (Moderate)
Purple: 301-500 The air quality is critical (Serious).
Reminder:
Pollutant-related risks vary with exposure levels (mild to extreme).
Formaldehyde: Tiredness, headaches, sleeplessness, skin and eye irritation, allergies, eczema,
breathing difficulties, etc.
Fine particles PM2.5: Breathing discomfort, nasal and bronchial irritation, other signs of irritation, etc.
That’s why it’s important to measure indoor airborne concentrations, which are important criteria when
drawing up room air-change regulations.
Important: the short-term actions above are intended only as a guide. They cannot be considered a
substitute for legislative or regulatory provisions or any other obligation that may exist. More specific
actions may need implementing. The values detected by the tester at a given moment can often be
higher than the exposure threshold. That’s why each threshold is coupled to a specific exposure time.
If the measured values regularly exceed these limits, a professional diagnosis is advisable to identify
the source of the pollutants. In the case of public buildings and venues, seek expert advice from the
relevant authorities, e.g., Regional Health Board or equivalent, Regional Environmental Office, etc.
