@sueinmn I found a research article on PubMed Central published by Dr. Falkinham, Dr. Honda and two others with in depth details of their study of water purification methods and the results. It does state that there was total removal of NTM by the LifeStraw Go Bottle they tested. It also had results for the SteriPen which was not quite as effective but more effective than the Mountop system. It's a very detailed article and for those that want to get right to these findings, you will need to scroll down into the results area for the specific headings for the LifeStraw and SteriPen products. Hopefully it's okay to post this link:
