When is air healthy and when is air unhealthy?

Basically, there are very simple answers, the confusion and the complicated answers to this rather simple question often comes from lobbyists who often do not think of ordinary workers and citizens, but of their lobby associations trying to protect them! For a worker in a mechanical engineering company, for an employee in an office or for a chef in his commercial kitchen, the air is healthy and harmless if it shows similarly low pollutant loads as healthy air in, for example, a tourist area in the Black Forest!

Or in other words, if air in a city, such as currently in Stuttgart, for example, classified as unhealthy and particulate matter alarm is triggered, then the same pollution in a commercial kitchens or in a mechanical engineering production can’t be considered acceptable for health and harmless, or ?

Then compare the harmful limit values ​​of pollutants from cities and interiors in which they are produced, these limits differ in some cases by a factor of 200! That’s not possible? Unfortunately it is, read more about this in our current documentation on limits in breathing air on pages 34 to 39: http://webkiosk.reven.de/english-reven-air-cleaners/59410010/34
