6 Simple Practices for Cleaner Indoor Air

April 22, 2026

Did you know that we take about 23,040 breaths a day? That number is an estimate based on typical breathing rates, and each breath delivers not only oxygen but also tiny particles and fumes that can affect our health.

Indoor air can contain unwanted pollutants too, and reducing your exposure to them can help your lungs feel better and support overall well-being.

Why Does Cleaner Indoor Air Matter?

Many everyday activities and products can release things into the air that make breathing harder or irritate the lungs. For example, tobacco smoke and other fine particles in indoor air can worsen breathing symptoms.

Some air pollutants are linked with higher chances of lung cancer and chronic bronchitis, especially over long periods of exposure, so it’s helpful to reduce sources when you can.

What Pollutes Indoor Air?

Common indoor pollutants can come from smoking, the products we use, and household activities.

Examples include:

Tobacco smoke and secondhand smoke
Chemical fumes from paints, varnishes, and cleaners
Particles from cooking or candles
Fumes from attached garages or vehicles

Six Simple Practices for Cleaner Indoor Air

1. Carpool or Walk When Possible

Driving less can reduce transportation-related pollution. Even setting up a plan to carpool or walk twice a week can help reduce emissions over time.

2. Use Manual Gardening Tools

Gas-powered lawn mowers and leaf blowers can emit exhaust into the air. Choosing manual tools helps avoid those emissions.

3. Consider Plants as a Bonus

While common houseplants have not been shown to meaningfully purify indoor air in real homes, greenery can be pleasant and contribute to a sense of freshness in your space.

4. Clean Air Conditioner Filters Regularly

Filters can trap dust, pollen, and other particles, helping keep the air cleaner. Check, clean, or replace filters according to the manufacturer’s instructions.

5. Improve Ventilation for New Furniture

New furniture and products can release chemical fumes (called volatile organic compounds) when they’re new. Opening windows when outdoor air quality is good and increasing airflow around new items can help disperse fumes.

6. Keep Tires Properly Inflated

Underinflated tires increase fuel consumption, which increases emissions. Checking tire pressure regularly can help your car run more efficiently and reduce pollution.

These small steps can add up over time and help make your indoor air feel fresher and healthier.
