Hey...what type of nebulizer thingy do you have...We were told the only ones you could boil were the PARI LC and then to do that as follows:
1. Wash in sink with hot water and soap
2. Rinse very well
3. Put in microwave safe bowl and fill with plain water
4. Set timer on microwave for 5 min.
5. Allow to cool and keep in a sealed type bag until used.
And even then they need to be replaced every 6 months.
NO boiling of tubing..just replace every 6 months
hope this helps <img src="i/expressions/face-icon-small-smile.gif" border="0"> have a good day
