Smoking is prohibited in most public spaces and private homes in the UK for good reason, but if you’re still determined to vape inside then you might need some extra precautions. The answer to “does vape set off smoke detectors?” depends on a few factors such as how close you are to the smoke alarm, and what type of smoke detector you have in place.

Generally, you’ll only be likely to trigger a smoke detector when you’re inhaling very dense clouds of vapor. This is because smoke and vapor have very similar density characteristics. If you’re in a room with a smoke detector, it’s also important to ensure the air is well-ventilated so the vapor can disperse more quickly. Using a fan, open window, or other such device can help to achieve this.

Does Vape Trigger Smoke Detectors? Exploring Detection Mechanisms

You’re also unlikely to set off a carbon monoxide detector, as this type of detector detects the presence of high concentrations of carbon monoxide, which is an entirely different compound to smoke or vapor. However, you should still be careful when you’re in an area with a carbon monoxide detector to minimise your chances of triggering it by accident.

The best way to avoid triggering a smoke detector when you’re vaping is to use a lower-powered device such as a pod system or stealth vape, which produces less vapor. Additionally, you can try switching to a liquid with a higher ratio of VG to PG as this will create a thicker cloud of vapor and reduce the likelihood of it setting off an ionisation or optical smoke detector.
