After a soapy soak, some people boil their equipment for 10 minutes every day or even after each use. Some boil once a week. Some sterilize using a baby bottle sterilizer. Even though we all aim to accomplish the same thing -- clean and sterilized equipment -- we each manage slightly differently. Really depends on one's disease state and risk tolerance. Since there is no home test for swabbing our equipment to find out if our method works, we look to experts like Dr. Falkinham, who published papers on NTM and its sources. His papers can be found in the ABC's on bronchiectasis thread. So you can decide what's right for you.

For me, it's a baby bottle sterilizer, Bololo, a few times a week for equipment sterilization. I have bronchiectasis without NTM (so far, working to keep it that way with 2x day clearance etc etc etc). Remember that sterilization of nebulizers etc is only one part of the equation for NTM, pseudomonas, etc avoidance.
