2 ways of calculation:
➡️ Simplified calculation: brief form omitting details at the expense of highly precise results
➡️ Detailed: more extensive form, fuller information, graphic analysis and refined results
🔹Suitable if a CO2 meter and / or HEPA filter is available

The monitoring of the CO2 level (NDIR technology) is a key tool, as an indirect indicator of
✅ The level of occupation of the premises
✅ Real-time ventilation efficiency
✅ Its relationship with the possible rate of transmission of diseases by aerosols
