A 4-hose hookah is specifically designed for group gatherings and parties, allowing up to four people to smoke simultaneously without constantly passing a single hose around.
Modern multi-hose hookahs use built-in ball bearing check valves inside each hose port. When one person draws smoke, their suction lifts the bearing to clear the airflow. Simultaneously, the bearings in the unused ports stay sealed tight to prevent fresh room air from leaking into the chamber, ensuring a thick smoke cloud for everyone.
