Secondhand smoke exposure platform • Science-backed data

The inhaleyou neverchose to take.

We make the invisible, visible.

You didn't light the cigarette.

You didn't choose to breathe it in.

But it happened — in your home, in a car, beside someone you love.

Invisible Inhale makes that hidden exposure visible. For the first time, see exactly what went into your lungs without your permission — and what it means for your health.

FAQ

Is secondhand smoke really dangerous?

Yes. There is no safe level of exposure. It contains thousands of chemicals, many of which are toxic or carcinogenic, as established by the Surgeon General.

Can air purifiers eliminate secondhand smoke?

Air purifiers may reduce some particles, but cannot remove all toxins or gases from tobacco smoke. Elimination at the source is the only guaranteed protection.

What are the best ways to protect my family?

Make your home and car smoke-free, encourage smokers to quit, and avoid places where smoking occurs.
