Poor outdoor air quality gets a lot of coverage on the news. What we don’t see on the news very often is the equally important issue of indoor air quality. If you think about it, you probably spend most of your time indoors. Some government agency is constantly monitoring outdoor air, but who makes sure that your indoor air is healthy? That task is left up to you.

Indoor air problems can cause a variety of symptoms and illnesses. Some bacteria is growing in a cruise ship’s ventilation system, or people in an office building get ill from a chemical spill on some other floor of the building. Those are both dramatic problems, but indoor air quality problems occur far more frequently than we know. Often sneezing, sore throat, nausea, and headaches can result from poor indoor air.

Causes of Air Quality Problems

Pet Dander

If you have pets, you may have an indoor air quality problem. No matter how much you love them, dogs, cats, and even birds leave sheddings on furniture, rugs, and carpets. Pet dander is composed of tiny pieces of dried skin that flake off whenever animals move, and dogs and cats add hair into the mix. Where do these tiny pieces of skin and fur go? Unless steps are taken to remove them, they stay in the household air.

High or Low Humidity

Indoor humidity levels are another air quality concern inside homes. In the winter months, air is drier because cold air holds less moisture than warm air. When the moisture levels drop too low, your nose and throat may become uncomfortably dry and static electricity will build up quickly. In the summer, humidity builds up in areas without adequate air circulation, which makes conditions right for contaminant growth.


The most common and serious indoor air quality problem is the presence of contaminants. Contaminants likes dark, humid environments like basements and air ducts. Contaminants reproduce by releasing tiny spores, and these spores will travel with the slightest draft. That means that contaminants in your air ducts needs to be removed immediately. Once contaminants are in a home, it can be a real challenge to get rid of it.
