It’s thought more than 5.5 million people worldwide die prematurely every year because of air pollution.
The effects of particulate matter (PM) on human health have been extensively studied.
The experts all agree that fine dust can be a serious health hazard, contributing to and, in some cases, even causing respiratory and cardiovascular diseases.
A much less known fact is that research indicates that these smallest particles in the air are the most dangerous.
To provide a healthy and productive indoor air environment, this means that the focus should be put on filtering particles that are 1μm (micrometre) or smaller in diameter – particles also known as PM1 (Particulate Matter 1).
The human body has no protection against these very small particles.
They enter our bodies through the respiratory system – we inhale them – and a significant number go deep into our lungs and continue into our blood stream.
It’s these PM1 particles that contribute to many serious conditions including heart attacks and lung cancer.
So where do these particles come from? The main culprits are the emission of small particles (1μm (micrometre) or smaller in diameter – particles also known as PM1 (Particulate Matter 1)) from power plants, factories, vehicle exhausts and from the burning of coal and wood.
The average person breathes in about 18,000 litres of air per day. Each litre contains some 70,000 visible and invisible particles.
That’s over a billion particles per day that our lungs must filter out.
In fact, the average home collects about 1lb of dust per week! A 3m x 3m carpet or rug will collect an average of about 4.5kgs of dust per year. Every day we eat 1kg of food, drink 2kg of fluid and breathe 25kg of air.
25 million particles
We can only see with human eyes 10% of what’s in our indoor air.
Indoor air is up to 50 times more polluted than outdoor air. We spend approximately 90% of our life indoors and every breath contains approximately 25million particles.
