My nebulizer is called “Drive” Power Nebultra. I’ve been using sine 2018 (i think). It was prescribed by my Pulm. And Rxd thru Medicare. I did not buy it and did not have a copay. If this helps. My Levalbuterol neb fluid takes about 10-12 mins (longest) and budesonide another 8-10 mins. Separated by waiting time of 20-30 mins. I also use an Aerobika flutter valve attached to nebulizer for Levalbuterol, but not with steroid (as instructed by Dr). There should be no water in your tubing, that does not need to be washed. If you washed it, you should through it away. Because the tubing will become moldy as you cannot get the moisture out. I hope this helps.
