The kind of biological pollutants commonly found in your home come from living organisms or fragments of them. Bacteria and viruses, pollen, dust mites, pet dander, and cockroach parts are among these organisms which invisibly float around in our indoor air usually without us even being aware of them. It's true that this is not a nice thought, but the fact is that biological pollutants can be found in pretty much every home and cannot be gotten rid of entirely.
It is worth noting, however, that certain environments help bio pollutants to thrive so if you want to reduce the amount of them, you will want to avoid creating those environments. For example, bio pollutants require nutrients and moisture to thrive. Bathrooms, damp basements, or any other areas with high levels of humidity are ideal for this. Air conditioners and humidifiers are also prime breeding grounds for bio pollutants so make sure that they are thoroughly cleaned, and filters are changed on a regular basis. Did you know that even some modern building materials and construction methods can increase levels of bio pollutants in the home? One reason for this is because they are designed to prevent outside air from entering the house.
Why should you be concerned about biological pollutants? As we have mentioned, bio pollutants can contribute to poor indoor air quality and are known to cause certain illnesses. If you feel your health is being affected by this problem, though, always be sure to consult your physician for an accurate diagnosis first.
