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

⚠️ People with asthma, allergies, children, and the elderly are more sensitive to poor indoor air.

⚠️ 6 Common Household Items to Use More Mindfully
1. Scented Candles & Air Fresheners
They may smell pleasant, but many release fragrance chemicals like limonene or phthalates.
When limonene reacts with indoor ozone, it can form formaldehyde, a respiratory irritant.

Burning paraffin wax (a petroleum by-product) can also emit soot and VOCs, similar to those found in car exhaust.

✅ Safer tips:

Choose beeswax or soy candles with cotton wicks

Avoid synthetic fragrances — use essential oils sparingly

Always ventilate the room while burning candles

Limit use if you or someone in the home has asthma or allergies

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

2. 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
