The Smoke Buddy Original Air Filter is a device that is used to eliminate smoke and odour when smoking cannabis and other substances. It is a small and easy-to-carry device that consists of a plastic shell and a replaceable carbon filter. When the user exhales smoke into the device, it is filtered through the carbon filter and the filtered air is then released through a one-way valve which prevents the escape of smoke and odour. It is intended for personal use and is discreet and effective, making it a popular choice for those who wish to smoke cannabis or other substances without attracting unwanted attention or producing a strong odour.
