The Critical Role of Indoor Air Quality in Homes for Big Families & Remote Workers

Introduction

We spend about 90% of our time indoors — in our homes, offices, and schools. Environmental Protection Agency+1
For households with many occupants and remote workers, the quality of the air inside matters more than ever.

Why IAQ Matters for Big Families & Home Workspaces

• More people in a space means more everyday pollutants: carbon dioxide (CO₂), moisture, cleaning / cooking by-products, and volatile organic compounds (VOCs).

• Remote workers are especially affected. A U.S. study found that homes used as workspaces showed measurable declines in cognitive performance when IAQ conditions were worse. CDC Stacks+1

• One study found that the fine particulate matter (PM₂.₅) levels in many homes during remote work were higher than in the same workers’ offices before the pandemic. Texas A&M Stories

Key Statistics to Know

• Only 27% of families who experience indoor breathing issues attempt to improve them by introducing air purifiers. HouseFresh

• In one study, virtually 100% of home offices used during remote work had particulate matter concentrations above WHO or national health-based standards. HouseFresh+1

• Cooking and other indoor activities release around 10 %–20 % of the total indoor VOCs in many homes. HouseFresh

What This Means for Your Home

• If many people live together or you’re working from home, your home isn’t just a residence – it’s a combined living, working, and learning space. The air quality directly impacts health, focus, and comfort.

• Higher occupancies and more varied uses increase risk factors: inadequate ventilation, unfiltered HVAC systems, more pollutant sources (cleaning, pets, cooking).

• Regular checks and strategic mitigation matter: better filtration, more fresh-air exchange, monitoring of CO₂ and particulate levels help safeguard the indoor environment.

Practical Tips for Homeowners

• Monitor key indicators: CO₂ levels, PM₂.₅, humidity.

• Increase ventilation: open windows when weather allows, ensure HVAC filters are appropriate (look into MERV ratings).

• Reduce pollutant sources: choose lower-VOC products, use exhaust fans in kitchens, limit indoor burning (candles, wood stoves).

• For remote workspaces: ensure you're in a room with good airflow and minimal pollutant load, especially if used by multiple people or for long hours.

Conclusion

Indoor air quality is a foundational component of home safety and occupant well-being—particularly when many people live together or work from home. Prioritizing IAQ means healthier lives, more productive workdays, and a more resilient home environment.
