Indoor Air Quality: 6 Common Household Items That May Affect Your Lungs — And How to Use Them Safely

5. Gas Stoves

Gas stoves release nitrogen dioxide (NO₂)carbon monoxide, and fine particles — all of which can contribute to asthma symptoms, especially in children.

Safer tips:

  • Always cook with the range hood on, vented outdoors if possible

  • Open a window during and after cooking

  • Avoid using the stove to heat your home

  • Consider electric or induction cooktops for a cleaner alternative

 Even short-term cooking without ventilation can spike indoor pollution.

6. Old Carpets & Dust Traps

Carpets — especially older ones — trap dust, pet dander, mold spores, and chemical residues from past spills or treatments.

Vacuuming without a HEPA filter can actually release these back into the air.

Safer tips:

  • Vacuum weekly with a HEPA-filter vacuum

  • Remove shoes indoors to limit tracked-in dirt and toxins

  • Consider replacing old carpets with hard floors or low-pile rugs

  • Use a dehumidifier in damp areas to prevent mold

Soft furnishings can act as both comfort and pollution sources — balance is key.

How to Improve Indoor Air Quality — Simple Daily Habits

You don’t need expensive gadgets to make a big difference.

Try these practical steps:

  • Open windows daily — even 5–10 minutes helps flush out stale air

  • Use exhaust fans in kitchens and bathrooms — especially while cooking or showering

  • Keep humidity between 30–50% — too much encourages mold; too little dries airways

  • Ban smoking indoors — secondhand smoke is a serious health risk

  • Test for radon — an invisible gas and leading cause of lung cancer in non-smokers

 Radon test kits are affordable and widely available at hardware stores.
