Click in your flavour pod, hold the device about 3 cm from your mouth, and mist for 3 seconds. That’s it. Use it whenever you need a refresh - before meetings, after meals, or on the go.
Get up to 6 hours depending on your lifestyle and diet. Many customers find they use it just 2–3 times a day to stay feeling fresh.
Most gums and mints mask odour with sugar or artificial flavouring. Cool+ Spray uses an ultra-fine mist and a probiotic blend to target the root cause of bad breath, helping support your oral microbiome, not just hide it.
Plus chewing-gums rank 2nd among the most polluting wastes on the planet. Most of them are composed of synthetic and non-biodegradable plastics which causes 250,000 tons of waste each year, 80% of which is dispersed into the environment and the sea.

On average, a pod lasts about 30 days with regular use. Heavier use may shorten that time, so we recommend keeping a spare pod or two handy - especially if you like rotating flavours.

It’s small enough to slip into a pocket or handbag, and safe to carry on flights. Just follow standard airline rules for liquids.
No - and we don’t recommend that.
Cool+ Spray is designed to complement, not replace, your regular oral care routine. Think of it as a powerful boost between brushes.
