The biological pollutants that are usually found in your home come from living organisms or parts of them. Common types of bio pollutants are dust mites, bacteria and viruses, cockroach fragments, pollen, and pet dander. Most of the time these organisms invisibly float around in our air at home without us being aware of it. While this is a very unpleasant prospect, biological pollutants are found in practically every home and are impossible to get rid of entirely.
Although it is pretty much impossible to remove all biological pollutants from the home, you could try to prevent the kinds of environment where they are more likely to thrive. For example, biological pollutants require moisture and nutrients. Ideal places for this are bathrooms, damp basements, or other areas that have higher humidity levels. Humidifiers and air conditioners can also become breeding grounds for bio pollutants so be sure to clean them thoroughly and regularly. Even certain modern construction techniques that prevent outside air from entering the home could contribute to an increase in bio pollutants.
Biological pollutants are known to cause several health issues. If you are worried that you are being affected by them, be sure to consult your physician for more advice.
