The patented Amy Deluxe® smoke chamber system is greatly improving your Shisha / Hookah smoking experience, due to smart engineering. The base has four chambers, the "flow passages". The smoke always travels through these chambers as they are positioned directly below the hose ports/blow off valves. Because of that the smoke always has to travel through the bowl. This way, when blowing out smoke, it will no longer accumulate in the Shisha / Hookah and all "old" and harsh smoke can be blown out at once. As a result there is no more harsh smoke, coughing and throat tickle.
