Springtime Indoor Air Quality Checklist


Indoor Air Quality Checklist for Homeowners

Whether your air conditioner is old or new, the whole family relies upon it to bring cool, fresh, clean air into living spaces to make HOME a comfortable, safe place. The need for clean air is enhanced when any family member struggles to breathe due to problems with allergies, asthma, or compromised immune systems. If you seek to improve the indoor air quality in your home, here are some steps to help.

Pollutant Sources

Indoor air quality is improved by removing the largest number of airborne particles possible. Where do these pollutants come from?

  • Organic sources. This includes pollen, mold spores, mildew spores from outside, and viruses and bacteria from virtually everywhere. It also includes dust (human skin cells), dander (pet skin cells), pet hair, and microscopic dust mites that feast on many of these nutrient-rich particles.
  • Many manufactured items, such as carpets, furniture, glues, and finishes like paint or stain, give off volatile organic compounds. (They are the source of that NEW smell we associate with new installations.) The release of these gaseous compounds diminishes over time, but they will always be present.
  • Inorganic compounds. Our indoor air also includes exhaust, blowing dirt, and industrial gases; the volume of these items depends on location. We also introduce various particles when we cook, clean, and complete common grooming tasks.

Dilution Techniques

These items WILL be found in the average home in various concentrations. The key to improving indoor air quality is removing a portion of these particles. There are several ways to dilute the number of pollutants inside.

  • Introducing fresh air from outside. The US Environmental Protection Agency estimates that indoor air is 3 to 5 times as polluted as outdoor air. Opening windows and doors for short periods will push some of these particles out. However, outdoor air temperature varies greatly, so pick appropriate times for opening windows.
  • Reduce the amount of pollen, mold, and mildew spores by recognizing specific seasonal allergens. DON’T open windows when the pollen count is very high. Remove clothes and shoes quickly after entering the home during the height of allergy season.
  • Regular cleaning. Most airborne particles are heavier than air; gravity will cause them to fall when the air is not moving. Clean these particles off surfaces regularly by dusting, vacuuming, and mopping. If your home includes a pet, it may require more frequent cleaning.
  • Use cleaning supplies wisely. Choose healthy toiletry and household cleaning solutions to reduce the number of toxins introduced to the indoor air.
  • Removing particles inside. This can be accomplished by using various pieces of equipment; some equipment comes standard in most homes, and some are valuable additions.

Dilution Equipment

  • Air filters. Each HVAC system moves a tremendous amount of air through an air filter about five times per heating or cooling cycle. Air filters remove most airborne particles. If you need enhanced filtration, discuss this with your HVAC technician to determine the most efficient filter your system can handle.
  • Ultraviolet lights. UV lights installed inside the ductwork will neutralize organic pollutants, including pollen, viruses, bacteria, and dust mites. The cells die and become inert matter collected by the filter.
  • Air purifiers. There are various options for enhanced air purifiers; room-sized or whole-house versions are available. These components use a series of filter types to remove both solid and gaseous pollutants.

Use the equipment and techniques that best meet the needs of your family.
