Carbon dioxide is a heavy colorless gas that takes up 0.03% of the
Earth`s atmosphere. Although CO2 is not toxic in Its nature, Its
concentration in the atmosphere should be controlled.

When its concentration in the atmosphere exceeds its normal
measurements at 400~500ppm, you may experience difficulties
in breathing (at 1,500ppm). headache and buzzing in the ears
(at 4,000ppm). higher concentration of CO2 in the atmosphere
measuring up to 5,000ppm can even endanger your life

CO2's concentration in the air increases with the consumption of
fossil fuels and the respiration of living aerobic organisms.
Continuous and thorough monitoring of the concentration of
CO2 in the air is vital.
