If you find that you’re sneezing indoors, you may need to look to your IAQ (indoor air quality). IAQ in the typical American home is often as bad or worse than that found outdoors. Airtight construction of newer homes may be a key factor in promoting a buildup of pollutants, leading to allergies and other breathing problems.
If you’re concerned about the indoor air quality in your home, you may have considered getting your ductwork cleaned. Many companies advertise duct cleaning as an effective way to improve the quality of your indoor air using before and after images showing extremely dirty ducts next to immaculately clean ducts.
