Good air quality in the home provides the environment all of us need to live comfortably and stay healthy.

Why is good air quality important? If you suffer from respiratory conditions such as asthma or allergies, you know how important it is to reduce the odds of a flare-up or full-blown respiratory attack.

Here are some things to know about improving the air quality in your home.

Poor Air Quality Triggers

In addition to the after-effects of sewer or water damage, there are many every day biological contaminants that reduce indoor air quality and can trigger an asthma or other respiratory attacks.

  • Mold and mildew due to excessive moisture in and around the home
  • Bacteria and contaminants from water damage or sewer backups
  • Dried rodent droppings (which become airborne)
  • Contaminated insulation, carpeting

Three Ways to Improve Indoor Air Quality

Eliminate Sources of Poor Air Quality

Getting rid of the source of indoor pollutants can help improve indoor air quality.

Indoor pollutant sources include, but are not limited to:

  • Building materials (flooring, carpeting, furniture, remodeling materials)
  • Black mold and other types of fungus
  • High humidity levels (above desired humidity level of between 30-50 percent)
  • Inadequate ventilation

Improve Ventilation

A simple solution to improving indoor air quality is to let more outdoor air inside.

Even the most energy efficient HVAC system can’t bring fresh air indoors. Here are ways to bring fresh air inside:

  • Open doors and windows.
  • Running fans or an open vent window air conditioning unit.
  • Exhaust fans to not only eliminate contaminants from a bathroom or kitchen but increase the outdoor ventilation rate if vented to the exterior.

There are three different ways to ventilate your home:


From outside air entering the home through doors and windows


Outside air gets into your home through leaks, cracks, broken seals


Forced air controlled by your HVAC system

Keep in mind that venting is especially important when working directly with contaminants. It’s important to increase ventilation while using oven cleaners, bleach or strong cleaners, paint stripper, paint, or while sanding, staining wood, using gas appliances or the fireplace.

Clean the Air

Air cleaners are available for purchase in a wide range of models and price ranges.

To be effective, look for an air cleaner that both traps indoor air pollutants (efficiency rate percentage) and for how much air is processed through the filter (measured in cubic feet per minute).

Both an efficient level of trapping pollutants and amount of air processed through cleaning filter must be in place to make a difference in air quality.


One of the most common reasons for reduced air quality in the home is due to sources of moisture and dampness found in crawl spaces, basements, kitchens and bathrooms. This is because among other things, excessive moisture breeds bacteria and causes mold to grow, which decreases the air quality in your home.
