How to Measure Passive Smoke

Secondhand smoke—also known as passive smoking—can seriously harm your health, even if you do not smoke yourself. Fortunately, there are several methods available in Switzerland to assess and reduce exposure to secondhand smoke in your home.

1. Passive smoke detectors (MoNic badges​)

Residents of the cantons of Geneva, Vaud, and Neuchâtel have access to a simple, cost-effective method for detecting the presence of nicotine in the air:

How it works​:

        • Place the MoNic badge in a room in your home.
        • After the exposure period, send the badge to CIPRET-Genève.
        • CIPRET-Genève forwards it to an accredited laboratory for analysis.
        • You will receive a detailed report indicating the nicotine level in your home’s air.

Cost: CHF 10 (includes the badge, analysis, and report)

Legal use: The report can be used as evidence in your dealings with neighbours or the landlord to request smoking restrictions.

How to get one:
Register and request your badge from CIPRET-Geneva

2. Analyses via cantonal laboratories (throughout Switzerland​)

If you live outside the cantons of Geneva, Vaud, or Neuchâtel, you can still request an air analysis from your cantonal laboratory:

How it works​:

        • Contact your cantonal laboratory directly.
        • Ask if they offer air quality or nicotine testing for private homes.
        • Most services are fee-based, and rates may vary by canton.

3. Installing home air filtration systems​

To reduce or eliminate exposure to secondhand smoke—especially if you cannot prevent it at the source—home air filtration systems can be a useful solution:

What to look for​:

        • HEPA filters and activated carbon filters are the most effective at removing smoke particles and odors
        • Choose systems designed specifically to address indoor air pollution.
