Measuring and defining air quality is difficult and complex, and with the exception of oxygen, nitrogen and carbon dioxide, the air contains a number of contaminants that are harmful to people. These are present in the air we breathe.
This lab station is equipped with highly advanced measurement equipment to detect different particle sizes. The smaller the particles, the easier it is to inhale them. The larger the particles, the easier they are to capture in a filter.
This station demonstrates why high-quality air filters are required for good protection against traffic pollutants, for example.
Are you protected?
This station shows the air quality at our current location. It measures different particle sizes both before (outside) and after (inside) the filter and then displays the efficiency
of the filter. The concentration of particles of different sizes will depend on a lot of things. For example, combustion particles are small, while pollen particles are much
larger. The lab station will indicate that the most difficult particle to filter is around 0.4 μm. Small particles, also named nano particles, penetrate through the human
barrier in the alveoli out into the blood and cause cardiovascular problems. They represent 99% of the particles in air.
