What are bacteria and viruses?
Bacteria and viruses can easily be distinguished by their size. Bacteria are up to a hundred times bigger than viruses. Most bacteria have a diameter of approximately 0,6 to 1,0 micrometres (µm). They can be seen through a normal light microscope.
The much smaller viruses can by contrast only be distinguished with an electron microscope.
Bacteria are unicellular organisms. They are everywhere, but are invisible to the naked eye. The average size of a bacterium amounts one micrometre, a thousandth of a millimetre. There are malignant and benign bacteria. If malignant bacteria reach the body, they may cause diseases because they produce toxic substances.
Viruses are much smaller than bacteria. If they get into the body, they can also be causing diseases. Some viruses can make the body dangerously sick. Viruses live and multiply within the smallest parts of the body, the cells. If there are too much viruses in one cell, the cell is destroyed. If too many cells are destroyed, one may get sick or can even die.
What are bacteria doing?
They grow and multiply. The better the conditions for a bacterium, the faster it grows and multiplies. Each multiplication means, that out of one bacterium, two new bacteria can develop, which again divide into two new bacteria and so forth. If conditions are favourable, an E.coli bacterium can divide within 20 minutes. This means that after 20 minutes, two bacteria have emerged out of one and after 40 minutes 2x2 = 4 and after an hour 4x2=8. After 24 hours there are approximately 1.000.000.000.000.000. 000.000 (a trillion billion)!
What are viruses doing?
Each person gets continuously into contact with potential pathogens like for example viruses. Sometimes the virus penetrates into the body and an infection develops. If the virus spreads more and more, ailments will appear. The body reacts to the invader with an inflammatory reaction. The substances that are thereby liberated lead to illnesses. The symptoms depend on the characteristics of the virus, but also on the part of the body or the organ that is contaminated by the virus.
Colds and flus are the most common viral infections. Many viral infections are transmitted by handshakes or coughing. Cold and flu viruses can be located on the nasal mucus and in the saliva. The viruses spread through droplet infection while we are talking, coughing or sneezing. This mostly happens in rooms where people are sitting close to each other or that are poorly ventilated, for example in trains, busses, schools or kindergartens.
Deactivation of airborne microorganisms like bacteria, viruses, mould and spores
The purifying effect of Clean Air Optima air purifiers deactivates bacteria, viruses, mould and spores in the air. It reduces the risk of being subject to allergic reactions and transmitting bacteria and viruses to a minimum.
