What is indoor air quality (IAQ)?

This is one of those simple questions with a sometimes-complicated answer. It refers to the air quality in and around buildings. In other words, the level of pollution and how it affects or relates to the health and comfort of the people inside. According to the EPA, indoor air quality in your Denver, CO home or business can have immediate health effects, or they may not show up until years later.

For some people, the effects are more an annoyance than anything else.

Symptoms like red watery eyes, scratchy throat, and sinus problems. For others, it can mean dangerous asthma attacks and severe respiratory problems. When testing indoor air quality, you must look at several components:

  • Particle allergens (dust, pollen, mold spores etc.)
  • Chemical pollutants (a few sources are carpets, upholstery, and paints & stains)
  • Carbon monoxide (a byproduct of any type of combustion or burning)
  • Carbon dioxide (naturally present in the air but unhealthy at high levels)
  • Humidity (humidity levels play a large role in IAQ problems)
  • Temperature

This is a good time to point out a well-maintained and properly functioning air conditioner helps improve and maintain your home’s indoor air quality. It’s another reason why calling Builder’s Heating & Air Conditioning for regular A/C maintenance is so critical. Your air conditioner filters the air as it circulates which makes changing your HVAC filters regularly even more important.  You can go one step further and install a home air purification system or UV lights. They will greatly improve indoor air quality compared to standard filtration. Your A/C also maintains a proper humidity level.

Another helpful step is to grow a green thumb.

House plants absorb carbon dioxide and give off oxygen improving you IAQ. A quick online search will tell you what are the best plants that improve indoor air quality. Just remember, this will have NO impact on the levels of carbon MONOXIDE. Testing for the presence of this deadly gas and correcting any problem requires the services of a professional HVAC technician.
