How to Look for Signs of Poor Air Quality

Signs of an indoor air quality problem in your home include musty odors, condensation on windows, discoloration of walls or ceilings, wood warping and peeling or chipping of paint. How you feel is also a good indicator of whether or not you have a problem with indoor air quality.

Preventing Indoor Air Problems

When your home’s air is clean, your family breathes and feels better. Fortunately, clearing the air can be as simple as installing a Healthy Climate® filtration system.

Other steps you can take to improve air quality include:

  • Test your home for radon, the leading cause of lung cancer among nonsmokers, according to estimates from the U.S. Environmental Protection Agency. Some states offer free or discounted test kits to the public. Information can be found on
  • Install a carbon monoxide alarm near all sleeping areas.
  • Make sure no one smokes in your house.
  • Clean regularly to get rid of dust mites, which can aggravate allergies and asthma.
  • Make sure anything that burns gas is vented to the outdoors.
  • Use cleaning supplies, paints, and hobby products that are labeled as low- or no-VOC (volatile organic compound).

The Right Humidity Levels can Make all the Difference

Properly humidified air feels better, AND allows you to heat and cool your home at more energy-efficient temperatures. A Healthy Climate® Dehumidifier removes excess moisture from your home’s air. Healthy Climate humidifiers add moisture as needed to keep it comfortable.

Impacts of Excessive Humidity

Indoor air that’s too damp feels sticky on the skin, and requires more heating or cooling to feel comfortable. Excessively moist air can also serve as a breeding ground for dust mites, mold, mildew and fungus, and it can ruin furniture, books, clothes and leather items.

What Happens When Air is Overly Dry

Indoor air that’s too dry can leave skin feeling itchy and dried out. Overly dry air can also increase static electricity, create cracks in furniture and leather, shrink wood floors and furnishings, and cause breathing difficulty or even nosebleeds. When nasal passages dry out, the body can become more vulnerable to respiratory viruses.
