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

occasional use is likely fine — just don’t make it a daily habit in closed spaces.

. Non-Ventilated Cleaning Products

Strong cleaners like bleach, oven sprays, or ammonia release harsh fumes that irritate lungs and eyes.
Mixing certain chemicals (e.g. bleach + vinegar) can even create toxic chlorine gas.

Safer tips:

  • Opt for natural alternatives like vinegar, baking soda, or castile soap

  • Always open windows or use exhaust fans when cleaning

  • Wear gloves, and don’t inhale directly — even with milder products

  • Store cleaners safely away from children and pets

 Even “green” cleaners can release VOCs — read labels carefully.

3. Plug-in Air Fresheners & Automatic Sprays

These products release fragrance continuously, contributing to long-term exposure. Some contain phthalates, which have raised concerns in hormone-related studies on animals.

 Safer tips:

  • Use them intermittently, not constantly

  • Place them in well-ventilated rooms

  • Try activated charcoal, houseplants (like spider plants or snake plants), or HEPA purifiers for natural freshness

 Remember: a clean-smelling home isn’t always a clean-air home.

4. Pressed Wood Furniture & Particleboard

Often used in desks, shelves, and cabinetry, these materials can emit formaldehyde — especially when new or low-quality.

 Safer tips:

  • Look for furniture labeled CARB Phase 2 or TSCA Title VI compliant — both ensure low formaldehyde emissions

  • Let new furniture off-gas in the garage or a sunny room before bringing it inside

  • Improve airflow in newly remodeled or furnished rooms

  • Consider solid wood options if budget allows — they last longer and emit fewer chemicals

Even the glue and varnish used on furniture can impact air quality — ventilation helps.
