Some of the health problems related to biological pollutants are frequent headaches, dizziness or tiredness, fevers, stuffy nose, dry throat, and difficulty breathing, etc. If you or any members of your household are experiencing these, ask yourself, do the symptoms disappear when you spend some time out of doors?
Another question to ask yourself is have you recently moved house or had any work done to your home such as the installation of storm windows, weather stripping, insulation, or some other kind of energy conservation work? If the answer is yes, did your symptoms start during or after the move or remodel?
Does moisture tend to collect on hard surfaces like windows, ceilings, and walls? Do you smell moldy or musty odors in the home that would be an indication of moisture intrusion? Does the air indoors feel humid?
Have you recently cleaned your humidifiers or air conditioners, or has it been a long time since they were done?
Are there any problems with pests in the home such as rodents or cockroaches, etc.?
If you have found yourself answering yes to all or even a few of these questions, biological pollutants may be affecting the air quality and environment inside your home.
