@ana323 Did you check the Lifestraw site? AI is not necessarily a reliable source.

From the Lifestraw website:
"The first, most common filter used in LifeStraw products is a membrane microfilter capable of blocking particulates and pathogens larger than 0.2 microns in size (effectively removing microplastics based on size exclusion). In general, nanoplastics are too small to be blocked by this filtration pore size. " (https://lifestraw.com/blogs/news/filtering-microplastics-and-nanoplastics-from-drinking-water)

Based on this statement, and on the recognized standard for filtering out mycobacteria (.2 micron filter) it looks to me like LifeStraw meets the criteria. Remember, they cannot list every bacteria removed.

@sueinmn This would be great! I sent email to them to confirm....because I'm neurotic. Thank you so much.

@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:

@sueinmn totally agree. I use the lifestraw products. I do weekly cleaning of the pitcher and dispenser and I do a deep cleaning 1x a month. I do it at the first of the month along with other things that need changed.
I've found their support very helpful. I've emailed many questions for details and although it might take 3 days to get a reply they always reply and answer every detail I ask.
