Should the presence of airborne particles in your home be of concern?

Airborne particles can be harmful to your health if they are 3 microns or less.  Small airborne particles can easily travel deep into the lungs.  The health risks associated with inhaling airborne particles include respiratory symptoms such as wheezing and coughing.  Children and pregnant mothers are at a higher risk for developing health problems associated with inhaling airborne particles, such as cancer, asthma, cardio-vascular disease, premature delivery, and birth defects.
