Each day we take around 25,000 breaths of air and some 14,000 litres (3,000 gallons) of air passes in and out of our lungs.

But floating in that air are absolutely billions of microscopic particles – dust, soot, pollen, viruses and bacteria. And that’s outdoor “fresh air”. Inside the home it gets even worse! – Indoors there are also particles of fabric, paper, hair and skin from people and their pets – not to mention the notorious dust mites and their droppings.
