When it comes to our health and wellbeing, the quality of the air we breathe plays a major role. Most of us are aware of pollution levels in our outside air, but how much thought is given to our indoor air quality? Did you know that indoor air quality is often worse than outside air? One of the reasons for this is biological pollutants. What are they and could you find them in your home?


Biological pollutants are generally derived from living organisms or fragments of them. Some of the most common types found in the home are pet dander, dust mites, cockroach parts, pollen, bacteria, and viruses. These organisms which are often microscopic are present in our indoor air and are found in pretty much every home. It is also impossible to rid your home of them completely.


Although we’ve established that biological pollutants can be found in most homes, are there certain conditions thaA hallway with a mirror and table in itt would increase their levels? Biological pollutants require moisture and nutrients so there are some environments such as bathrooms, damp basements, or places with high humidity levels where they will thrive. Air conditioners and humidifiers are also breeding grounds for this type of pollutant, so it is important that they are cleaned out regularly. Some modern construction techniques can also be a contributing factor.


For some people, biological pollutants can be the source of many health problems. If this is something you are concerned about, make sure to consult your doctor for advice.
