Purge is when you blow out the smoke from the chamber to clear it. That is really weird about the hose... Amira maintains that it is a surgical grade silicone so it should not ghost (hold the flavors like you are saying)..

but a cleaning with baking soda and hot water followed by a through rise in cold water should wash all the flavors out. I clean my hookah and bowl after every session to get the fullest flavor possible.

The Amira has a very wide gauge downstem, so a shallower phunnel bowl might work better than a deep bowl. So to improve your setup, I'd definitely get a HMD, and a bowl that holds it well. You can make that a 2 hose hookah very easily, if you watch this video https://www.youtube.com/watch?v=T6lfhYd_y4U. You might not be able to get a KL in SA, but you can def get a chimney, that would be my goto in case I could not get access to a HMD. something like this. https://www.amazon.com/Silicone-Narghile-Charcoal-Narguile-Accessory/dp/B078SP1LF6. Ratings are BS. If you are enjoying your session and don't burn the tobacco, It's a 10/10.
