@blm1007blm1007 I have the Ombra compressor. I use both Aeroeclipse XL and Pari LC Sprint nebulizer cups with the Ombra compressor. The Pari nebulizer cups come with their own wing tip tubing, but I have been using the Pari cup with the Aeroeclipse tubing as I started with the Aeroeclipse cups, and will still use if I am short on time and decide to do my Aerobika while I nebulize, which is a nice perk of the Aeroeclipse. Generally I do my Aerobika separately from nebulizing. I replace the tubing each month so will eventually use the Pari tubing, it looks similar to the Aeroeclipse tubing and should work interchangeably. Yes, again, I use the Pari LC Sprint nebulizer cups. I also ordered my supplies at Save Rite Medical. I confess I didn’t do too much (if any) shopping around as I was in the thick of all the “start up” and just followed suggestions from this group on what and where to buy. Good luck with the sputum testing!
