Toxic Indoor Air: The Invisible Threat to Your Health

Did you know indoor air can be up to 100 times more polluted than outdoor air?

What’s Polluting Your Home’s Air?

Your home may feel safe, but it’s often filled with hidden pollutants.

Cleaning, cooking, and candles release harmful particles.
Paint, furniture, and other household items emit toxic gases.
Spending 90% of your time indoors amplifies exposure.

The Hidden Effects of Indoor Air Pollution

Each breath you take could carry pollutants that harm your body.

Pollutants accumulate in organs, causing allergies, fatigue, and brain fog.
Long-term exposure increases risks of heart disease, memory loss, and cancer.
