Particulate matter (fine dust) only exists in big cities, outside, on busy streets?
A mistake! In fact, the fine dust pollution indoors is often many times higher than outside! The pollution caused by fine dust does not begin and end at the front door.
The WHO places fine dust in the same category as formaldehyde, nitrogen dioxide or carbon monoxide in terms of its health-endangering effects. Because the dust particles are so fine that they penetrate even the finest ramifications of the lungs and even get into our bloodstream.
The smaller the particles, the more dangerous they can become for our health.
In recent years, a large number of scientific studies have been published that show the negative effects of fine dust on health, including damage to the lungs, heart and blood vessels.
