Indoor air quality is a significant factor in household health, with the U.S. Environmental Protection Agency noting that indoor pollutant levels are often two to ten times higher than outdoor levels. Modern, energy-efficient homes may exacerbate this issue by being built airtight, which can trap pollutants inside.

Common indoor irritants include dust mites, mold, pet dander, and pollen, which can trigger allergies and respiratory issues like asthma. Children are identified as a particularly vulnerable group. 

Beyond biological allergens, chemical exposure from conventional cleaning products is a concern. Research indicates these products can emit hundreds of volatile organic compounds (VOCs). Management strategies to improve air quality include regular HVAC maintenance, using allergen-proof bedding, switching to non-toxic cleaning products, and utilizing air filters.
