If you search there are discussions on nebulizers. Everyone has a different preference. Personally I have always used either the Pari Vios or the Pari ProNeb Max. That is the compressor part of it. Then you also need the nebulizer or the cups called Pari Sprint or Pari LC Plus. When you order the cups they come with the tubing. So you basically have three parts: the compressor, the cup, the tube. At first it seems complicated but once you get into the routine it is not. You should replace the tube every two weeks since it cannot be cleaned. To dry it out after use you detach the cup and run the compressor with the tube (I hang mine over a dining chair back) for 3 minutes to dry it out. Then store it someplace it will stay clean. The cups you need to follow the directions for cleaning and disinfecting. But it becomes routine. The saline can be prescribed by your Dr and picked up at a pharmacy. It is called hypertonic saline 3 or 7%. 7 is more effective but some people only tolerate 3%. You can also order the hypertonic saline on Amazon and if you need the link i can message you with it. I get all my Pari equipment at justnebulizers.com. They are fast. But there are other places online. I hope this helps. Most people follow the nebulizing with the use of something called an Aerobika. It is a flutter device you breath with in a certain way to loosen the mucus. It is just as important as the nebulizing in my opinion. You could just start with the nebulizing as this all must sound like alot!
